Roller shutter air filter, also known as automatic winding filter, is an air dust removal equipment that converts the pressure difference before and after the filter into a sensing electrical signal and automatically replaces the filter material. The main material is made of polyester fiber, with a layer of fiberglass mesh cloth on the surface. When the cotton is wound up, a paper tube is added in the middle, which can be directly placed on the automatic winding filter for use. It can be controlled by the machine without the need for manual replacement of the filter cotton. After all the filter cotton is used up, it can be replaced uniformly, which not only saves labor costs but also improves work efficiency.

Characteristics of automatic winding filter:

1. The rolling shutter filter is made of compressed glass fiber, which has good strength and elasticity.

2. The air outlet surface of the rolling shutter filter can be reinforced with a grid weave to enhance its shape. In addition to strengthening the firmness of the filter material, it can also guide the air to form a uniformly distributed laminar flow effect, without compressing the filter material together due to wind resistance, which will affect the dust holding capacity. And it will not deform or cause fiber flying under vibration and rolling. The contaminated filter is wrapped inside, which is not only easy to replace but also clean and hygienic.

3. The filter cotton is sprayed with a special adhesive to enhance its ability to capture dust. The lifespan of the rolling shutter filter is long, and it does not require frequent replacement of the filter screen, reducing replacement costs.

4. The outer frame can be made of cold plate spray coating, aluminum alloy profiles, and 304 stainless steel.

5. The overall structure is made of metal, which is sturdy and reliable, and can meet the requirements of harsh working environments.

6. The CHF rolling shutter filter adopts photoelectric control to achieve precise filtering of rolling shutter materials.

7. The photoelectric control adopts a large LCD screen to display the operating status, with on-site sound and light alarms, and timely reminders to replace new filter materials.

And reserve a remote alarm interface for remote operation.

8. Modular assembly and intelligent filter material replacement system can meet the requirements of complex airflow systems, save energy, reduce manpower, and operate more economically.

9. Suitable for various ventilation and air intake purification occasions, especially for low-pressure and high air volume supply systems, the air purification effect is particularly ideal.

10. We can customize various specifications of automatic roller shutter air filters according to customer requirements.

Technical parameters:

1. Filter configuration: G4 filter cotton
2. Equipment configuration: Electrical control signal output terminal
electrical machinery*4pcs protection level: ≥ IP55

3. Filter cotton specification: 1000 * 150000 (replaced five times): Well grid backup mesh cotton
4. Operating environment humidity: 90% RH; Operating environment temperature: -10 ℃~+40 ℃.

usage method:

1. The new filter material is installed in the feeding box. When the air conditioning inlet air with high concentration of dust passes through the winding filter, the pressure difference before and after the filter gradually increases with the increase of filter dust.

When the resistance of the filter rises to the set final resistance value, the differential pressure switch starts to operate.

After receiving the operation signal, the controller immediately turns on the motor power and automatically starts the motor.

4. The operation of the motor drives the scroll inside the feeding box to rotate, thereby winding up the dirty filter material and replacing it with clean filter material on the filtering section.

5. The displacement of the filter material during operation is controlled by a grating for distance operation. When the filter material reaches the preset length in the manipulator, the manipulator will send a signal to the motor,

6. Disconnect the power supply and the motor will stop running.

7. It is not necessary for personnel to go to the top of the equipment to replace the filter material. A bracket slide can be used in conjunction with a linkage device for replacement.

8. Adopting industry covered filter materials, the structural form is mostly arranged in a density gradient combination, which has good ventilation and dust removal ability, low resistance, high strength, stable chemical properties, high temperature resistance, odorless, non-volatile, and easy operation.

Application places of roller shutter filters:

Sewage treatment plant blower inlet air filtration, textile plant air conditioning return air filtration, industrial ventilation for equipment cooling, central air conditioning inlet system pre filtration, metallurgical industry sintering system purification, power plant gas turbine inlet system pre filtration, highway equipment room or culvert ventilation, subway and civil air defense engineering ventilation, coal industry tunnel high air volume ventilation with high dust content, requiring frequent replacement of filter media environment;

A constant airflow operating system.

Automatic rolling shutter air filters, bag filters, and plate filters are used in central air conditioning systems, metallurgical sintering, chemical industries Ventilation systems such as electronics, sewage treatment, power plants, coal mine ventilation, subway ventilation, civil air defense engineering, etcDomain.
