Flanged Compressed Air Filters - TRF* Series
The flanged compressed air filters and elements provide high-efficiency filtration for flow rates from 23 to 320 m³/min. Engineered for high contaminant-holding capacity, strong corrosion resistance, excellent temperature tolerance, and long service life, these filters ensure reliable removal of impurities from compressed air systems.
The flanged filter adopts a multi-layer construction, combining borosilicate, glass fiber, activated carbon fiber, non-woven fabric, and stainless steel mesh. This advanced multi-stage filtration guarantees the delivery of oil-free, contaminant-free compressed air, supporting superior air quality across industrial applications that demand large flow capacities with consistent performance.
"*" stands for filtration grade
- Grade C filtration: solid 3μm, oil content 3ppm
- Grade T filtration: solid 1μm, oil content 1ppm
- Grade A filtration: solid 0.01μm, oil content 0.01ppm
- Grade X filtration: solid 0.01μm, oil content 0.003ppm
- Grade H (activated carbon) filtration: solid 0.01μm, oil content 0.001ppm
- Grade F high efficiency dust removal: 0.1μm
- Grade FF super high efficiency dust removal: 0.01μm
