Automatic Roll Air Filters for High-Volume HVAC and Process Air Systems

Introduction

Large industrial facilities, such as waste treatment plants, manufacturing sites, and large HVAC installations, require continuous clean air intake. Traditional filters often face rapid clogging and frequent replacement in these environments. The automatic roll air filter (ARF) is designed as a motor-driven prefiltration system that ensures reliable air quality under heavy dust loads.

What is an Automatic Roll Air Filter?

An automatic roll air filter uses a roll of nonwoven media that advances automatically when dust accumulation reaches a set resistance level. This automatic media progression ensures consistent airflow and eliminates the need for constant manual monitoring.

Key Characteristics

• Stable pressure drop maintained over long operating cycles

• Continuous operation with minimal maintenance

• High dust-holding capacity due to large filter surface media

• Flexible frame materials: galvanized steel, aluminum alloy, or stainless steel

• Efficiency grades: G3 / G4 according to EN779

Why Stable Pressure Drop Matters

In high-volume HVAC and process air systems, stable pressure drop is critical. Fluctuations in pressure reduce system efficiency, increase energy consumption, and strain downstream HEPA or fine filters. By maintaining a consistent pressure drop throughout the filter’s service life, automatic roll filters:

• Protect fans, blowers, and heat exchangers

• Extend the lifespan of secondary filters

• Lower overall energy and maintenance costs

Industrial Applications

• HVAC intake systems in airports, hospitals, and large commercial buildings
