No belts and no routine maintenance
The Secomak 669/HP3 is a direct drive centrifugal blower: the impeller sits straight on the motor shaft, so there is no belt or bearing assembly to wear out. On an Australian 50 Hz supply it delivers up to 1,200 m³/h of air and up to 33 mbar from a 0.55 kW three phase motor.
The 669/HP3 is the high pressure three phase version of the 669, rated by Secomak at up to 1,200 m³/h and 33 mbar on 0.55 kW. Direct drive blowers pair easily with Secomak air process heaters when hot air is needed.
Only essential components are used, which keeps the blower compact and cost effective and means there is no routine servicing. Secomak has built industrial fans and blowers in the UK since 1930, and every blower is hand built and tested before it leaves the factory.
