panel prefilter with metal frame

1.It is normaly prefilter used in air conditianer system

2.choose good quality's synthetic media

3.choose metal frame

4.filteration efficiency (test by weighing dust):90%-95%

5.efficiency rate :G1-G4

6.a welded wire grid ,spot welded on one inch centers and treated for corrosion resistancece ,to maintain the radial pleat velocities

7.thinkness:17mm ,21mm ,25mm, 46mm

8.media and wire formed in radial pleats for high duat loading

9.radial pleat configuration for full use of the media area and high dust holding capacity

10.a media to frame sealant ensuring that all of the air seen by the filter will be treated by the filter .frame to media for high dust is eliminated
