Forced draft industrial fans
Forced draft (FD) fans are most often associated with the supply of combustion air to boilers, particularly in power generation where the forced supply of oxygen increases the heat transfer rate and enables a smaller boiler to produce more heat.
Control of the airflow utilising variable speed or damper control of the fan may be required. Clean-rooms or operating-rooms may require constant pressurisation of the space and FD fans are ideal for these applications. However, noise may constitute a problem in such applications and filters and acoustic enclosures may be called for.
