Denotation of product types
 
● The screen material of air filter is of high performance non-woven fabrics, an anti-cracking synthetic fiber without breaking danger as that of glass fiber, which reduces the risk of breaking leakage.
●The screen material of gas filter is of progressive increase structure, namely the density of fiber layer in the clear air direction increases progressively.
● The screen material of air filter is processed for its viscosity. The binding agent fully permeates into the fiber so as to block particles.
● The filter features large quantity air wind with low pressure loss, high filtering efficiency and reliable operation.
● The filter performs combination filtration suitable to different filtration needs.
● Unique filter assembly design ensures to replace and maintain conveniently
● The filter element doesn’t contain PVC coloring agent and balogen. It can be used for foodstuff grade filtration.
Typical applications:
●Combustion turbine, centrifugal compressor inlet filtration
●High pressure blower inlet filtration of power plant, foodstuff and beverage factories
●Purification systems of pharmaceutical, Chemical, Metallurgical and biological engineering industries.
●Central air conditioning and ventilation system
