Automatic Roll Air Filters for Subway and Tunnel Ventilation Systems – Clean Air Solutions for High-Flow Environments

Subway systems and underground tunnels present unique air quality challenges. The constant movement of trains generates massive airflow, carrying dust, particulate matter, brake residue, and exhaust gases throughout the tunnel network. Without effective air filtration, these contaminants can harm ventilation fans, reduce air quality for passengers, and accelerate corrosion in critical infrastructure.
To address these demanding conditions, HICLOVER’s Automatic Roll Air Filter provides a robust, automated filtration solution engineered for high-air-volume ventilation systems used in subways, metro lines, and transportation tunnels worldwide.

Continuous Filtration for High-Volume Airflow

Conventional filters in subway ventilation shafts require frequent manual replacement — an expensive and time-consuming task in confined underground environments. The Automatic Roll Air Filter from HICLOVER uses a PLC-controlled automatic media replacement system, continuously advancing new filter media while rolling the used material onto a collection reel.

This automatic system ensures:

• Consistent air purification under continuous high airflow conditions.

• Reduced labor and maintenance downtime in hard-to-access ventilation shafts.

• Stable differential pressure across intake and exhaust ducts.

• Improved passenger and worker safety by reducing airborne particulate pollution.

Built for Harsh Subway and Tunnel Conditions

Designed for underground tunnels, metro stations, and air shafts, HICLOVER’s filters use reinforced steel housings and high-tensile drive motors built to withstand humidity, vibration, and high-pressure ventilation currents. The Automatic Roll Air Filter effectively captures brake dust, oil mist, soot, and suspended particulates from high-speed airflow — helping maintain clean, breathable air and extending fan life.

The modular design allows easy integration into HVAC systems, air exchange shafts, and exhaust corridors, offering both vertical and horizontal installation flexibility.

Intelligent and Energy-Efficient Operation

The Automatic Roll Air Filter automatically activates when pressure sensors detect filter resistance reaching preset limits. This intelligent control maintains energy efficiency by preventing fan overload, optimizing airflow, and minimizing downtime.
Its PLC control panel supports remote monitoring, ideal for metro authorities managing large-scale underground networks.
