Pre Air Filter Synthetic Fiber Auto Roll Air Filter for Large Particle Dust

Product Introduction:



Automatic winding filter is actually a new type of air filtration equipment, it is through the pressure difference before and after the filter is converted into a sensing signal, the realization of filter material replacement automation equipment. Explosion-proof winding filter is used in chemical plants and other special industries, with inflammable and explosive medium hidden danger of special filter equipment



The working principle of



It is mainly composed of filter material, explosion-proof transmission system and explosion-proof automatic control system.



The new filter material is installed in the feeding box, when the air with high concentration of dust through the winding filter, the pressure difference before and after the filter increases with the filter dust and gradually rise; When the filter resistance rises to the set final resistance value, the differential pressure switch starts to act, the winding system updates the filter material; When the curtain time is reached, stop the transmission, update the filter material work is finished, re-filtration.

B Applicable occasions Flammable and explosive gases are class B gases (including Class A gases)

T4 The maximum surface temperature of the equipment does not exceed 135 degrees



Material: high quality cold rolled steel, aluminum or SUS 304



Control: manual, time/differential pressure control, photoelectric control, PLC control



Filter material: special covering mesh filter material, G3, G4 (EN779) efficiency



Installation: the finished products can be operated only by electricity on the delivery site. If the installation space on the site is limited, the products can be packaged and shipped in pieces, and then flexibly assembled and formed on the site



Product Application:



 Effective filter for large particulate matter in the fresh air of the clean room to provide more qualified air into the clean room



 Effectively prevent the appearance of stains around the fresh air inlet of air conditioning, long after the service life of the high efficiency filter;



 Effectively prevent the waste water treatment plant blower dust accumulation serious, installed in the front of the blower blower to provide effective protection



 For chemical plant, textile factory, spraying workshop and other air filter system for primary filtration, remove most of the particulate matter, effectively improve the quality of exhaust gas and circulating gas.
