It is very important for element design and material.
Element Struction
FPM seal ring ensure the air-tightness between filter head and filter element, to achieve a positive filtration Effect.
Double stainless steel support layer to ensure the fulter element strength, deep bed Multi-wrap borosilicate glass microfibre large flow passage prevent high pressure drop.
With 96% porosity high dirt holding capacity, lifespan up to 6000 to 8000 hours. The general differential pressure is 0.17~0.25 kg/cm, less than 0.65kg/cm.
The element cover is made of PA+GF, free from deformation at 1.8Mpa pressure and high temperature of 240℃ and capable of resisting general acid and alkali chemical corrosion and withstanding the severe compressed air environment.
Special material for the outer layer of filter element, with strong hydrophobic and oilphobic, prevent the oil or water being blown away and received drying and filtering effect.
