RFE: Tube fans of seires RFE and RFG are axial flow fans with integrated guide fan. Both sides of the fan can be fitted into the tube and be fixed with fast clamps.
The housing is made of injection moulded PP in black. The series is designed in a way that by putting on a flange on each side of the housing the actual size becomes the next smaller size. Efficient storing facilities are the result. The fans have protection class IP 44. These fans have a 3-step single-phase motor. For simple controls, a step switch is sufficient. More fine tuned control can be achieved by standard controllers for single phase AC. The performance curves in this catalogue have been established using the inlet test method in the test chamber according to DIN 24 163, mounting position B. The curves indicate the static pressure increase ΔPfa as a function of the volume flow. This type of inline tube fans are directly mounted into the tube, fixed by clamps. Due to the very low height these fans are ideal for use in false ceilings. Please refer or download our catalogue for more information.
