Fans for Ventilation and Air Conditioning


Scroll casing with backward curved profile blades – double inlet

The high-performance RDP fan is a double-inlet, direct-drive centrifugal fan with backward curved blades. With a combination of integral motor, lightweight aluminium impeller and on-board electronics, it is particularly compact and robust. This makes the RDP the ideal partner where you are looking to replace a fan with a more energy-efficient product, for example. Modernisation always pays off.
