Mount the Polyfan2 in the wall of your greenhouse and connect it to a 240volt single phase power supply.

Individual fans may also be purchased in the form of the single outlet INF90C blower unit or the INF160C twin outlet fan is a 160cfm air flow fan and is supplied with two connector outlets which fit inside the 65mm air transfer pipe.
Note: Always use a qualified electrician to connect and appropriate RCD protection to suit individual application. 

Twinskin air pipe flanges are designed to securely hold the 65mm air transfer pipe in place where it enters the twinskin cladding. These two piece flanges have a locking flange and spigot part, that lock together to form a tight seal and solid connection point for the air pipe where it enters the inner layer of the twinskin. 

Twinskin ribbed pipe 65mm – the ribbed is used to transfer the inflation fan air from the fan unit or in between the various sections of the twinskins covering. The pipe is supplied either per meter or in a 30m length coil.

Redpath Manometer air pressure gauges are a simple water gauge to measure twinskin air pressures. Instructions are supplied with each gauge.
