The company has an industry-leading clean room workshop and a variety of imported production equipment, and has a development team composed of top overseas software, hardware and structural engineers, and has a comprehensive R&D design strength and production process technology.

When we buy anything new, we always have to get familiar with it for a period of time. Although any product comes with a manual, most people still don’t bother to look through the lengthy manual. Therefore, Nanjing Yixiou lists the necessary operating procedures for the automatic roller shutter air filter for each customer:

Roll-up filter start preparation and operation before operation

l Check whether the equipment around is firm and swaying

l Check if sealing measures are done around the equipment to prevent unfiltered air from directly entering the back end of the filter

l Check whether the external power supply is properly connected

l PLC control system debugging (omitted), linked with the main control PLC system, debugged by the main control system manufacturer

Replacement operation of the old filter material of the roll-up filter

l When the entire roll of filter material is finished, the upper travel switch will act, the control system will transmit a signal, and the buzzer will alarm to remind the filter to be replaced;

l Operate the control panel on the electric control box, enter the manual mode, and roll up the dirty filter material;

l Raise the dirty filter material from the left to the right and lift it diagonally upwards to move it out of the right shaft. Then pull the dirty filter material to the right as a whole, and remove it from the winding tube of the old filter material;

    Installation operation of new filter material of roller shutter filter

l Press down the lock of the new filter box above to open the new filter box;

l Remove the stainless steel clip strips at both ends, take out the new filter material winding round tube, stuff it into the paper tube in the middle of the new filter material roll, and then stuff the new filter material into the new filter material box;

l Both ends of the round tube are clamped between the two short profiles, and then the clip is clamped into the profile groove, and the round tube is pressed tightly;

l After completion, pass the filter material through the lower part of the compression frame made of the square tube, and then pass through the gap between the top profile and the adjustment tube, pull down at a constant speed, pass through the front and rear steel bars all the way to the end, and cover the filter box. Lock the lock.

Precautions for the operation of the roller shutter filter

l The new filter material round tube must be stuck between the two short profiles, the plug is inserted, and the filter material needs to be placed forward to confirm the winding direction. If the surface where the filter material box is located is the front, look from the right side, the filter The material is rolled down clockwise;

l The new filter material must pass under the compression frame made of the square tube, between the front and rear compression bars;

l The new filter material should be pulled down at a constant speed, and the distance between the two sides should be symmetrical, and the edges of both sides should be stuck in the baffle plates on both sides to prevent air leakage;

l After the new filter material is installed, it must be manually wound to prevent it from falling off and causing the phenomenon of inclined winding;

l When the size of the equipment is too large, especially the height is high, safety protection measures must be taken when replacing the filter material.

At present, the new air outlets of clean ventilated central air-conditioning units in China will be equipped with automatic rolling curtain air filters as standard . 2016 we had the pleasure and the tip of Dalian, Guangdong Shenling many other well-known air-conditioning manufacturers supporting the unit fresh air automatic shutter filter, so for any reason after docking technology several times, a large area of a large volume of fresh air chambers will choose automatic roll Is the winding filter the preferred primary filter method?

Since the air sucked in by fresh air contains a lot of large particulate matter, it will affect the normal operation of the air conditioning unit, and also affect the service life of the medium and high efficiency filters inside the unit. The air inlet is equipped with a roller shutter filter with excellent filtering performance and automatic winding operation, which guarantees the high-efficiency and trouble-free normal operation of the air-conditioning unit to the maximum extent; minimizes the number of shutdowns. It greatly protects the service life and use effect of the back-end equipment, and is a good way to save energy and use costs. A good fresh air filter is a prerequisite for excellent air quality and product quality in a clean room. The fundamental reason is that the roller shutter filter has the following outstanding features, which can win the love of design units, air conditioner manufacturers, and users:

1. The filter material can be automatically replaced: this is the biggest feature of the automatic winding filter, and it is also the reason why it is more popular than other primary filters. The replacement principle of the automatic winding filter is that the geared motor drives the transmission system to work, and the dirty filter material on the filter section is wound through the tube shaft, and the entire width is replaced with a clean filter material. The entire filter is accurately refueled, without any material waste, does not require any labor, and the automatic control is far more timely and accurate than manual refueling.

2. Suitable for large-area places: It is very suitable for large-area ventilation and filtration systems. The width direction is limited by the filter material (the maximum width is 2m), and multiple units can be spliced to form a wider filter section. Due to the height of the factory building, there is a certain range in the height direction, and a height of 6m is sufficient for use.

3. Easy to operate: Compared with the shortcomings of plate and frame modular replacement, a lot of manpower and material resources are required for replacement. Each time the automatic winding filter changes the filter material, the automatic control is completely induced by the differential pressure switch and the motor is started. There is no need for personnel to participate. Only when the entire volume of filter material is exhausted, the entire volume of filter needs to be replaced according to the process material.

4. Low operating cost: Compared with the shortcomings of plate and frame modular replacement, when replacing a large area, the cost of discarding the plate filter and replacing it with a new one is considerable; while the winding filter only needs to replace the filter cotton that matches the equipment. And each roll of filter cotton can be used at least about 6 times as the primary filter, which greatly saves the later operating costs.

The above is a brief summary of the editor’s summary of the reasons for the automatic winding of the central air conditioning fresh air room. Authoritative experts are welcome to guide and judge.

1. The centrifugal fan roller shutter air filter equipment is composed of a filter box and an automatic air filter (two units in parallel)

2. This type of air filtration type has the functions of large processing flow, low resistance and high filtration efficiency, so that the filtration resistance is always constant at a certain value set by the inlet differential pressure switch, and it can automatically wind the filter material and alarm at the end of the material. The control box is equipped with exquisite three-color warning lights, and the inspectors can judge the working condition of the filter according to the flashing color of the warning lights.

3. Filter box body: is a 40*40 square tube welded anti-bird net frame, filter material replacement platform, 80 channel steel chassis, main box body welded by high 5000mm, wide 4500mm and 6mm Q235 steel plate, Tianyuan local reducing joint and Composed of DN2200 elbows, this box can bear a negative pressure load greater than 15kpa, and the total weight is 7.8 tons. Thanks to the square tube frame support, the box can withstand greater negative pressure loads. The bird-proof net can prevent birds and other The fowls are sucked into the filter by the suction of the centrifugal fan. Due to the large size of the filter box, it needs to be welded and assembled on site.

4. The automatic roller shutter filter is a unique product with patented independent intellectual property rights, which is made up of the feeding box. Stopper bar, pressure bar, blanking box, column, reduction motor, transmission machinery, control box, imported differential pressure switch and winding filter material. When the filter is working, the filter resistance can always be maintained at the setting of the differential pressure switch When the resistance reaches a certain value, the wind resistance will be automatically updated and the wind resistance will drop, so that the wind resistance will always be maintained at a certain value, which can be controlled by no one. The material will alarm immediately at the end, and there is a dry contact remote transmission alarm by the operator The filter material is replaced. This type of filter has low resistance, large processing flow, and automatically updates the filter material, so that the motor of the fan will never be overloaded.

5. Automatic rolling curtain air filters are widely used in aeration and air inlet filtration of sewage treatment plants, air-conditioning fresh air inlet filtration, iron and steel plants, fan inlet air filtration and other industries.

6. The automatic winding air filter belongs to the initial efficiency level of air filter, which belongs to G3, G4 level (EN779). The winding filter adopts a stepped manufacturing method. The filter layer can effectively intercept dust particles in the air. The dust holding capacity of a square meter can reach 1kg, and each roll of filter material can be guaranteed to be replaced at least 6 times.

Warranty description: automatic rolling curtain air filter, when the equipment is installed, technicians will be sent to guide the installation on site, and free training will be provided to the owner and operators, so that they should know and should know.

As a clear stream in the air filtration industry, the automatic roller shutter filter can filter impurities and dust in the air in a large area. However, the diversified functions of the roller shutter air filter and the uneven quality of the brand have become a recognized fact in the industry. For users, the selection is also a big problem. The biggest confusion is that many roller shutter filter products are similar in appearance, but the actual prices are very different. Due to the relatively high price of a single unit, it is really very difficult to select a cost-effective manufacturer among domestic manufacturers. Some of them advertise their products with the highest market share, and those with the lowest prices of their own brands. Various market information is constantly bombarding us with business, which really hurt the purchasing staff.

With a realistic attitude, the editor has really compiled dry goods suitable for the selection of automatic roller shutter filters for the selection process, through multi-level comparisons, and more satisfactory results can be obtained.

1. Roller shutter filter is based on good technical performance

Whether the products of roller shutter filter manufacturers are based on mainstream technology design is the most important criterion for judging. Although there is no standard national standard for the roller shutter filter, there are already established standards in the design institute and professional and technical personnel, such as frame structure, transmission mechanism, and basic functions of automatic control. If the candidate manufacturer’s technology understands and can surpass these standards, then the roller shutter air filter is easy to get technical support, and its scalability is better. It can be unanimously recognized by the designer, construction party, and acceptance party. Due to the different production design and process technology of each manufacturer, the filtering effect is different. Although some manufacturers advertise low prices, they sacrifice the user experience and reduce the necessary functions. The consequences are definitely not worth the loss.

2. The roller shutter filter complies with the company’s equipment procurement strategy

In order to improve work efficiency and meet the needs of purification levels, companies are already formulating or improving procurement strategies. In this case, when choosing an automatic roller shutter filter, you need to consider whether it is in line with the company’s long-term procurement strategy. Our standard products are divided into local electric control cabinet control, standard remote control interface, and can be networked with the central control room. In the central control room, the operating status of the roller shutter filter, the missing filter material and the operation of the motor can be monitored. . It can fully match the customer’s development situation and connect with the upper-level central control PLC. At present, most suppliers do not have this function.

3. Roller shutter filters lead the development direction of filtration technology

Due to the rapid technological update of automation products, it may happen that the company’s winding filter standard formulation lags behind the filter technology update, which will lead to no standard basis for product selection. At this time, it is necessary to consider whether the candidate roller shutter filter conforms to the development direction of future technology. Although the price of some winding filters is low, customers are easy to be tempted by the price advantage when purchasing, but the automatic control function is weak, and the control system is an integrated circuit board, which is not conducive to the integration and improvement of the control system in the future. The control module is an integrated circuit board, which is not conducive to the maintenance and upgrading of the product in the future.

4. Roller shutter filter meets open and expandable requirements

The automatic roller shutter filter has good scalability, which means that the customer’s filtering needs change, the filter equipment can be adjusted and upgraded to match the variability of the demand, so that the original investment can be effectively protected and improved, so as to get a good overall Input-output efficiency. To meet the requirements of openness, not only is it required that the automatic roller shutter filter control system can be independent of hardware and PLC, more technical support can be obtained during system development and construction, and it is easy to upgrade, and the open control system can be integrated with existing information resources , The formation of a unified integrated centralized control, saving manpower, material resources and financial resources, so that it can become a true automatic control winding filter product.

5. Roller shutter filter manufacturers have successful application examples

The eyes of the masses are discerning. Generally speaking, excellent products or technologies will be more widely used. Therefore, in the process of selecting a winding filter manufacturer , try to investigate the application effect in related fields as much as possible. For the application of spray automatic rolling curtain filter, you can ask for application cases in the painting industry. Pharmaceutical factory automatic rolling filter can ask for application cases of pharmaceutical factory. The central air conditioning fresh air system can refer to the case of the large-area fresh air filter winding filter. Investigating the market share of candidate manufacturers’ technical products and cases in related fields are a powerful reference for product evaluation.

I hope that the above content will provide some help and guidance for everyone’s selection of automatic roller shutter filters. Our company’s automatic roller shutter filter products have a wealth of performance in the spraying industry, hospital medicine, laboratory clean workshops, etc. If you have any questions, please feel free to contact the professional sales staff of Nanjing Yixiou Company.
