The cardboard frame pleated air filter is mainly suitable for filtering particles with a diameter of 5um.It is made of non-woven fabricglass fiber and synthetic fiber by blending or polyester fiber as the filter material.The wedge-shaped folding shape has a large filtering areaand is equipped with a high-strength cardboard frame to make a plate structure.
The cardboard frame pleated air filter element is a kind of pre-filter,which is mainly suitable for filtering 5um particles.It is made of non-woven fabric,glass fiber and synthetic fiber by blending or polyester fiber as the filter material.The wedge-shaped folding shape has a large filtering area,and is equipped with a high-strength cardboard frame to make a plate structure.The balanced spacing and the design of double ribs ensure the contoured pleats of the filter net,so that the filter can achieve a large dust holding capacity when the resistance is small.Folded shape,the filter material is fixed diagonally at the front and rear of the outer frame,the filter material and the outer frame are tightly bonded to prevent any air leakage,and its filtering area is 2-5 times that of a normal plane.
Features:
1. High performance,strong structure Contour pleated design
2. Imported high-quality fluffy filter material,large dust holding capacity and good general performance
3. DK expanded pleated plate disposable filter adopts a complete set,hard mold cutting,contour pleated,double-layer moisture-proof and high-temperature resistant cardboard frame plate structure design,compact structure,light and convenient.
Filtration Efficiency:
G4(ISO 16890)
Applicable conditions:
Maximum temperature (°C): 93 (200°F)
Material:
1. Frame:paper frame
2. Optional thickness: 22mm, 44mm, 95mm
3. Filter material: a mixture of non-woven fabric and synthetic fiber
Resistance & air volume:
Based on 594*594*44mm 300E air flow m³/h
Application:
1. Pre-filtration of air-conditioning and ventilation systems to avoid dust accumulation inside the system from polluting large-scale air compressors.
2. Clean room centralized ventilation and air-conditioning system and return air filtration, prolonging the service life of the post-stage high-efficiency filter The ventilation system of ordinary industrial plants meets the general cleanliness requirements for air.
3. Coarse dust filtration system for air conditioners in general buildings
