Olmo REVR Range (Backward Curved Fans)

OLMO’s REVR range of fans are composed of an external rotor motor and a backward curved, single-inlet plastic or zinc-coated fan. The OLMO fan is directly coupled with the rotor, which is dynamically balanced with a degree of G 6.3. This means that the fan can be mounted in its housing without the necessity of vibration dampers.

The 190mm diameter fans are supplied with a plastic impeller; all other models are supplied with zinc-coated impellers. The standard product range offers a significant protection against corrosion under normal weather conditions

OLMO’s standard fan is single-phase rated 230V – 50Hz and/or 60Hz, 2 or 4 poles, insulation class “B” and internal protection IP44. On request alternative voltages and frequencies may be produced other than those under European standards.

Units are supplied with clockwise rotation from inlet side.
