Flange disc dust removal and purification filter 320 * 900 flame retardant film

The flange disc type 320 × 900 flame-retardant film dust removal filter cartridge focuses on the safety filtration needs of flammable and explosive industrial scenes. It integrates flame-retardant materials, efficient filtration, and structural reinforcement design, and has significant advantages in fire safety, purification efficiency, ash cleaning and regeneration, durability, and adaptability. It is the core preferred accessory for explosion-proof dust removal systems. Firstly,Flame retardant and fire-resistant safety, suitable for high-risk working conditionsThe core filter material adoptsPTFE flame retardant coating+flame retardant fiber matrixAfter special flame retardant impregnation process, it hasSelf extinguishing upon ignition, non combustible and non explosive, high temperature resistantCharacteristics: It can effectively resist sparks, high-temperature particles, and contact with open flames, eliminate the risk of dust combustion or explosion, and is suitable for flammable and explosive environments such as welding fumes, aluminum magnesium powder processing, wood dust removal, chemical powders, etc; The flame retardant rating of the filter material reachesUL94 V-0 levelThe maximum operating temperature can reach 180 ℃, and it can maintain structural stability and filtration performance even under high temperature and spark splashing conditions, laying a solid safety line for high-risk dust removal systems. Secondly,Efficient membrane filtration with high purification accuracySurface coatingMicro porous PTFE film, forming a "surface filtration" mechanism, with stable filtration accuracyF8 级 （0.4μm）The filtration efficiency for fine dust, smoke, and powder particles is ≥ 99.9%, which is much higher than that of ordinary filter cartridges; The surface of the film coating is smooth and non sticky, which can effectively intercept sub micron dust, prevent dust from embedding into the deep layers of the filter material, prevent the attenuation of filtration efficiency, and maintain high purification effect even after long-term use, ensuring that the exhaust meets the standard and the workshop air is clean. Thirdly,Pulse self-cleaning regeneration, long lifespan and low resistance. AdoptingExternal inlet and internal outlet airflow design+dense folding structureThe effective filtration area is 3.8-4.5 square meters, with an initial resistance of ≤ 120Pa and an operating resistance of ≤ 280Pa. It can be cleaned online with a pulse blowback system, and the dust on the surface of the film can be instantly peeled off without residue. The filter cartridge has excellent regeneration performance and a service life of up to8000-12000 hoursExtended by more than 30% compared to ordinary filter cartridges; After self-cleaning, the resistance quickly recovers, avoiding a surge in wind resistance and an increase in fan energy consumption. It is suitable for continuous operation of high concentration dust and reduces the frequency of shutdown maintenance. Fourthly,Flange disc seal, securely installed and leak proof. AdoptingThickened carbon steel flange disc end cover, MatchingHigh strength metal frame+inner and outer protective meshThe overall structure has strong rigidity, outstanding resistance to compression, deformation, and pulse impact, and can withstand back blowing pressure of 0.6-0.8MPa. It can operate for a long time without collapse or damage; The flange end face adoptsAging resistant nitrile rubber gasketHigh sealing adhesion, effectively blocking unfiltered air bypass, preventing air and powder leakage, and ensuring filtration efficiency; The disc flange design is compatible with standard chuck/bolt installation, easy to disassemble and assemble, and can be quickly replaced by a single person without the need for special tools. Five of them,Waterproof, moisture-proof and durable, suitable for multiple scenarios. Filter materialWaterproof and oil resistant immersionProcessing, with excellent moisture-proof, anti condensation, and anti oil adhesion properties, can operate stably in environments with humidity ≤ 95% and temperature -20 ℃~+80 ℃, and is not easily affected by moisture, mold, or powder blockage; The outer protective net adoptsGalvanized/stainless steel material, anti-corrosion, anti-aging, suitable for outdoor humid, dust, corrosive gas and other harsh environments; 320 × 900mm is a universal standard specification, suitable for various types of flange self-cleaning dust collectors, pulse dust removal equipment, welding smoke purifiers, and powder recovery devices. It has strong interchangeability, stable supply, mature domestic substitution, high comprehensive cost-effectiveness, and is an ideal choice for dust removal and purification in flammable and explosive working conditions.
