Product Introduction
Furnaces that run long and hot ask a lot of their exhaust blowers, and the Heat Resistant Boiler Fan 90W is built to answer. Air delivery sits at 350m³/h against 360Pa, enough for fireplaces, small central boilers and workshop heaters that need reliable negative pressure. Its 2800r/min two-pole motor runs on either 220V single-phase or 380V three-phase supply, and the high-temperature housing protects windings from radiated heat. Bearing set 202 front, 201 rear plus a 4μF capacitor keep operation smooth in single-phase mode. Units are packed two per wooden crate with a combined 15.5kg weight, an arrangement that trims freight bills for dealers and multi-unit buyers. For retrofit work, the Heat Resistant Boiler Fan 90W bolts straight onto most standard flue collars. Mounting points line up with ordinary boiler flanges, and the impeller can be wiped down after a season of use. Technicians often pick this rating when a 60W model is too weak for a longer chimney run. Make the switch to the Heat Resistant Boiler Fan 90W for fewer blockages and a noticeably fresher boiler room this winter.
