Replaceable Air Filter

2025/08/21

The key data of the Replaceable Air Filter is as follows: Model RA2146, filtration class to EN779 is G3/G4, standard air volume is 4250m³/h (G3) and 3400m³/h (G4) respectively, face velocity is 3.3m/s (G3) and 2.7m/s (G4) respectively, initial pressure drop is 100Pa (G3) and 85Pa (G4) respectively, average capture efficiency is 88% (G3) and 90% (G4) respectively, recommended final resistance is 200Pa, standard product size is 592x592mm (customizable, optional overall depth of 46mm and 21mm), and effective filter material area is 1.0m².
It is applicable to the pre-filtration stage in ventilation and air conditioning systems, and can also be used in air intake systems, effectively extending the service life of high-efficiency filters. The filter medium is a progressive structure non-woven fabric made of tear-resistant synthetic organic fibers, which has the characteristics of high dust holding capacity, low pressure loss and stable filtration efficiency. Special properties include moisture resistance and structural stability under high relative humidity, heat resistance up to 70°C, filter materials meeting flame retardant standards (fire resistance), and filter materials with antibacterial, antiviral and mildew-proof functions.
