HS-Mikro Pak 4V compact lters serve as pre- lter and main lter when high ow rates and high initial efficiency are required. These filters offer more filter surface than the classic HS-Mikro Pak and can therefore achieve a higher dust storage capacity and thus longer service life. Thanks to the aerodynamically shaped inlet profiles, these filters offer significantly lower initial pressures than comparable filters from other manufacturers. The robust plastic frame is corrosion-free and allows easy disposal due to it's incenreability.

For applications with the highest demands, these filters can be reinforced on the clean air side with burst protection grids.
