Gas Exhauster Fans GXZ Fans & Blowers

In the early days of landfill gas extraction our customers adopted the well proven Fans & Blowers GB gas booster fan. Since those early years we have worked closely with our customers to evolve the GB design into a special purpose gas exhausting fan, the GXZ, designed for the arduous requirements of landfill gas extraction. By its nature, landfill gas compared to natural gas can contain many various contaminates including solids, H2S and water vapour.

The GXZ exhauster is therefore of robust construction, with drain plug, inlet & outlet flanges to PN16 (others available) fully welded gas tight casing. Casing, impeller, seal housing and motor pedestal all 304 stainless steel for maximum protection against internal and external corrosion. The gas seal at the point of shaft entry to the fan casing is the well proven Fans & Blowers double Viton lip seal, grease packed for lubrication and maximum sealing efficiency. Grease nipples are fitted to enable the correct re-greasing schedule to be carried out.
