Project Description

Hybrid fan with backward curved hollow profile blades

The new RQM MultiEVO combines the easy handling of free-running centrifugal fans with the effectiveness of traditional housing fans. In principle, it is a directly driven centrifugal fan with spiral-shaped guide vanes. The unique design of the guidelines and housing exceeds the energy savings of the free-running RQM fans and traditional EC fans significantly.

  • Up to 15 % more efficient than conventional or EC fans
  • Easy installation on the floor, wall or ceiling
  • Simpler component replacement while servicing and maintainance
  • Easy accessibility, for example, in case of cleaning


Always reach the optimal duty point with maximum efficiency – often at just one motor power rating lower than traditional free-running fans. Just plug in and switch on. Eachsystem solution comes parameterized and ready for operation – including a prior functional test and test run. That saves time and money.


Horizontal or vertical: Install the RQM MultiEVO with integrated electronics directly to the floor, wall or ceiling – without having to install the inverter separately outside of the system. An unshielded power supply cable is required for the connection. All components can be replaced quickly and easily. That makes initial operation, maintenance and service extremely easy.


Regular inspections of AHUs require absolute cleanliness. For this reason, when designing the RQM MultiEvo, we have taken care to ensure that the impeller is easy to clean via the guide vanes or the optional opening flaps. It can’t be simpler.
