Performance Specifications of Automatic Roller Filter
2025.08.24
The Auto-O-Matic air filter is a newly launched type of advanced air filtration equipment. The automatic roller-type air filter is a breakthrough in the traditional filtration field. It converts the pressure difference before and after the filter into a sensing electrical signal and automatically replaces the filter material.
The main frame material can be selected from cold-rolled sheet spray coating (Cold rolled sheet), aluminum alloy profiles (Al alloy), and stainless steel (Stainless Steel).
The overall structure is made of metal, which is sturdy and reliable and can meet the most harsh working conditions.
The automatic roller-type filter is controlled by photoelectricity, truly achieving precise control of the roller filter material.
The photoelectric control uses a large LCD screen for operation status display, local sound and light alarm, and timely reminds of replacing new filter materials.
It also reserves a remote alarm interface for remote control implementation.
The modular assembly, intelligent filter material replacement system can meet the requirements of the most complex airflow systems, effectively saving energy, reducing manpower, and operating more economically.
It is suitable for various ventilation intake purification occasions, especially for the air purification effect of low-pressure high-flow air supply systems.
Working principle:
The new filter material is placed in the loading box. When the air conditioning intake air with high-concentration dust-containing air passes through the roller-type filter, the pressure difference before and after the filter gradually increases as the dust filtering increases.
When the filter resistance rises to the set final resistance value, the pressure difference switch starts to act.
The controller receives the operation signal and immediately connects the motor power supply, automatically starts the motor.
The motor rotation drives the roller in the loading box to rotate, thereby rolling up the dirty filter material and replacing the clean filter material on the filtering section.
The displacement of the filter material is controlled by the grating. When the filter material rotates to the preset length in the controller, the controller gives the motor a signal, cuts off the power supply, and the motor stops rotating.
Replacing the filter material does not require personnel to go to the top of the equipment. It can be replaced by using a bracket slide rail and a linkage device.
The automatic roller-type air filter uses a special mesh filter material. The structural form is mostly arranged in a density gradient combination, with good ventilation and dust removal ability, low resistance, high strength, stable chemical properties, resistance to certain high temperatures, and no toxicity, odor, or volatility. The operation is convenient.

Technical parameters:
Filter efficiency grade: G3/G4 (EN779)
Air velocity: Suggested < 2.5 m/s
Final resistance: Suggested value 200 - 300 Pa
Power: 100 W
Power supply: 220/380V - 50Hz
Ambient air temperature: -10°C to +40°C
Ambient relative humidity: 90%RH
Control system:
A pressure difference controller is installed on the inlet face of the filter material. According to the user's usage environment requirements, the final resistance for filter material use is pre-set.
The control cabinet is equipped with a pre-set length for each update of the filter material, and the number of times the entire roll of filter material can be replaced is input into the computer chip of the controller.
When the motor starts to drive the reel for material replacement, the laser grid photoelectric control system installed on the top of the equipment begins to work, recording the length of the downward replacement of the filter material, and transmitting the recorded data to the PLC in the control cabinet.
When the recorded filter material movement data is the same as the preset data in the computer PLC, the PLC immediately issues an instruction to stop the motor from running.
