EC/DC Combustion Fans DSB144-22 HEV

The first combustion fan produced by Torin-Sifan was over fifty years ago. It was from this time that Torin-Sifan was able to establish itself as the clear market leader in the home market in the UK for the supply of combustion fans to the residential gas boiler industry.

Modern burner systems such as gas condensing boilers need to be supplied with a consistent flow of air-fuel mixture across all ambient conditions and operational modes.

The production of the complete range is in-house at our UK factory. This includes the winding and production of low voltage DC & 230 V EC motors and the final assembly of the blower.

The typical applications for boiler or combustion fans and blowers include domestic boilers, burners and equipment that requires a high-pressure air-flow delivery.

As with all Torin-Sifan products, the key is in the flexibility within our development and manufacturing processes – working closely with your own design team to ensure optimal design and performance of the fan for each application -meaning your products are at the forefront of their markets.
