JM short casing
Short cased axial fan
General ventilation and extraction, cooling and refrigeration, environmental control, crop storage, petrochemical process ventilation and emergency ventilation up to 400°C/2h.
JM Aerofoil fans short cased for duct or plate installation. Casings are spun from sheet steel with integral pre-drilled and radiused inlet flanges. The galvanised finish gives a high resistance to corrosion and is ideal for external as well as internal use
A unique high efficiency aerofoil section blade with a purposely smoothed hub and clamp plate for adjustable pitch angle availability.
The Fläkt Woods impellers are all high pressure die cast to offer thin aerofoil sections for low generation of noise.
Every cast aluminium component is X-ray examined using Real Time Radiography inspection prior to assembly.
The maximum pitch angles shown allow for speed control by frequency inverter (3ph only).
Squirrel cage asynchronous motors totally enclosed.Insulation class F and protection F
Suitable for horizontal through to vertical shaft operation
Sealed for life bearings lubricated with wide temperature range grease. The motors are fitted with overheat protection thermostat.
Supply:230V 1ph 50Hz or 400V 3ph 50Hz
