Frame material : Galvanized frame/ Aluminum alloy frame/ Stainless steel frame Frame thickness:10/21/46/96 etc Filter material:aluminum wave nets/stainless steel nets Maximum temperature:above 250â?? Maximum humidity:100% Optional aluminum depth 7~96mm Efficiency:G1 G2 (EN779)45%~95%@0.5�¼ Customized size: Available Packing : Inner packing is carton ,outer packing is pallet Port: Qingdao SPECIFICATION The metal mesh pre air filter adopt multi-layer expanded aluminum foil mesh or stainless steel mesh and the metal mesh is pressed into undulations and intersect each other at appropriate angles Metal meshes are arranged from thick to fine according to density and pore size, thus increasing the dust collection capacity and filtration efficiency. The initial resistance is lower than 20Pa. APPLICATION 1.The metal mesh pre air filter can used for clean room conditioning system ,pre-filtration through fresh air venting units ,and exterior air conditioning connection . 2.Primary filtration for central air conditioning system . 3.Pre-filtration at the intake of Air purification equipment . 4.Primary filtration in a filtration system . 5.Ventilation system for outdoor and other harsh environments. 6.Pre-filtration in Ventilation system for outdoor fire-proof and high temp resistance working condition .
