LMP Mini Prop
Propeller fans are by no means new to the ventilation industry. They have been in existence ever since a rotating blade was first combined with an electric motor. Probably the most reliable, robust and versatile air mover available, the LUFT series LMP ‘mini’ propeller fan continues to meet the demand for a competitive, easy to install ventilation fan. Available in six models, delivering volume flow rates of 300m³ to1700m³ per hour, the LMP ‘mini’ prop is no doubt the most cost effective air
mover in the smaller range of propeller fans.
The fans are produced in three diameters 200, 250 and 300mm. The aluminium impeller is formed to enable the fan to deliver an equal amount of air in both directions when fitted to the motor in a form ‘A’ or form ‘B’ configuration. This concept is shown on the reverse of this brochure.
Because of the smoother bell mouth entry, the blade delivers slightly more air when running in form ‘A’. The motor is supported by a rigid electro-galvanized wire guard, which is fixed to a pre-galvanized steel plate. The guard supports the motor and doubles as a protection screen to avoid accidental contact with the rotating impeller and prevents airborne objects from passing through the fan.
Totally enclosed shaded pole motors, specifically designed to match their respective impellers, are protected to IP42 standards, with sealed for life ball bearings and class ‘B’ insulation. Standard motors are impedance protected with thermal contacts for temperature ranges between –30ºC and +40ºC. All models are supplied with a short electrical cord, which may be
connected to a 15-amp switch socket or a suitable isolator at the fan. Exposing motors
to the weather or other arduous conditions should be avoided.
