The RA 15-60 is the perfect unit for the exhaust air rooms such as bathroom, WC and kitchen. Like the AB 30/60 it is an exhaust air unit with an ec-motor, which can also be combined with the LUNOtherm facade element. Due to the same design the e², RA 15-60 and AB 30/60 fans are predestined for hybrid ventilation, in which ventilation with heat recovery is combined with exhaust air technology in a cost and energy efficient manner. ... learn more
Lowest noise: Quiet at high pressure build-up
Radial fans are already known from the exhaust air series of LUNOS. However, this is the first time a radial system has been used in a 160 mm pipe. This combines the advantages of both designs: The quiet and pressure-constant running of the centrifugal fan combined with the renovation-friendly installation dimensions of the pipe fan. In addition, aerodynamically optimised fan blades in combination with the multi-surface sound absorbers give the RA 15-60 undreamt-of low running noise as well as optimum sound insulation from the outside.
Modern engine technology
The new radial ec-motor in combination with the pressure housing gives the RA 15-60 its exceptionally good pressure characteristic curve. Depending on the control program, the volume flow can be adjusted in three or four stages (15, 30, 45 and 60 m³/h).
Best performance for the environment
With a converted power consumption of only 0.04 - 0.12 W/m³/h, the RA 15-60 is unsurpassed in energy efficiency, thus making an active contribution to environmental protection and saving money.
