Product Overview
Ducted Ventilation
Powerflow models provide a compact yet versatile range designed with the installer in mind, combining the acoustic benefits of a tough plastic casing with the pressure characteristics of a centrifugal fan.
A range of eight models from 100 to 315mm dia. duct sizes. The 300mm dia. model has been specifically developed for use with rigid ductwork. Air volumes from 0.059m³/s to 0.42m³/s at free air and capable of pressure development up to 550 Pa.
Powerflow has 50-80mm long inlet and discharge spigots allowing easy installation and fixing. The adjustable mounting foot allows the terminal box to be rotated to any angle and allows plenty of space and adjustment for screw fixing. The robust fire retardant polymeric casing combined with outlet guide vanes ensures optimum airflow management through the unit.
