Pleated Pre Filter
Pleated primary filter mainly filters dust particles ≥5μ m. Mainly used in commercial and industrial ventilation systems, air conditioning system pre-filtration.
Product features:
· the outer frame is strong and detachable: it adopts a strong plate-type aluminum alloy frame with aluminum alloy Angle, and the structure is firm and stable to ensure that the filter will not be deformed or damaged in the poor working environment. The outer frame adopts a detachable design to facilitate the replacement of filter material to achieve the purpose of frame reuse;
· folding shape. In addition, the filter material is fixed diagonally at the front and back of the frame. The filter material is closely bonded with the outer frame to prevent any air leakage.
· the filter material is made of high-quality polyester synthetic fiber, which can be cleaned and reused many times with long service life; The fluffy and dense fiber structure ensures high dust accumulation rate and large dust capacity.
