DC/EC Combustion fans
A combustion fan pushes air at the right temperature and pressure into the chamber to ensure combustion. DC/EC combustion fans typically feature backward curved impeller designs suitable for higher speed and higher pressure operation 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.
Custom Solutions
The combustion fans can also be adapted to offer customised solutions. Options available can vary from plug type and mounting hole position to fully bespoke, low-profile designs for specific applications. If you’re interested in our customised solutions, take a moment to view the services we have on offer.
- Brushless DC or 110/230V EC motor drive
- Backward curved anti-static plastic impellers suitable for premix applications
- PWM speed control and tachometer feedback
