Air Fan Units
The Air Fan Purge Unit are easy to use and allows safe purging of gas to air in various circumstances, for example when decommissioning gas pipe work and vessels or pressurising pipe work for strength and tightness testing. If required, the Unit will work in conjunction with a Gas Purge Unit.
The Air Fan Purge Unit is mounted in a durable vinyl coated aluminium-framed box that provides a stable base when the Unit is operational. The Unit's fan is fitted with a check valve to prevent gas reversing into the fan assembly. Two different versions of the Air Fan Purge Unit are available for use with pipe work up to 150mm and up to 200mm. Both are compliant with IGEM Utilisation Procedures UP/1 and 1A.
