Flakt Woods 31JMV14/2/6/33 - Long Cased Axial Fan 315mm
All fans are tested to the latest internationally recognised
standard IS05801 Part 1 (1997), installation category
D (AMCA approved) for aerodynamic performance and
BS848 Part 2 (1985) for acoustic performance. Coupled
with a wide range of fan diameters, the adjustable pitch
Aerofoil impeller gives the exact performance required,
with a non overloading fan characteristic.
A unique high efficiency aerofoil section blade with a
purposely smoothed hub and clamp plate for adjustable
pitch angle availability.
The Flakt 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).
All motors are totally enclosed air stream rated class
F insulation. Constructed from aluminium or cast iron
as standard with special T slot or pad mounted fixings.
Single speed motors are suitable for speed control by
voltage regulation where indicated. Three phase motors
are suitable for use with frequency inverters. Two speed
motors where available are pole change type. Suitable for
horizontal through to vertical shaft operation. Supplied
IP55, with removable drain plugs.
Sealed for life bearings lubricated with wide temperature
range grease. The BT and CT frames are fitted with
overheat protection thermostat as standard. 80-160
frame motors are fitted with Thermistor OHP. These
motors are suitable for inverter speed control down to
20% of full speed and where within scope incorporate IE2
compliant motors.
-40°C to 50°C as standard. (All motors are not suitable
for starting at temperatures lower than -20°C.). When
fans are operating in excess of 50°C they should be run
at full speed only, fans can be operated up to 70°C with
appropriate deration of motors.
Most standard 3 Ph fans can be offered for a one off
emergency operation at 200 ÌŠC for 2 hour
