The Square bifurcated axial flow range of fans consists of 7 duty sizes with a maximum air flow of 5.60 m3/s. The units are manufactured from galvanised sheet steel to BS. 2989. 1982. All units are suitable for internal and external applications at any installed angle
Always handle the units carefully to avoid damage and distortion. Care must be taken to ensure that any slings used for hoisting do not damage the casing or fan impeller.
Installation must be completed by competant persons, in accordance with good industry practice and should conform to all governing and statutory bodies i.e. IEE, CIBSE, COHSE etc. The unit can be installed at any angle and is suitable for internal or external use. Ensure that the air flows over the impeller before the motor. The unit is flanged at both ends and can be connected to the system by either bolting directly to the ducting or via flexible connections [optional extra]. Optional mounting feet and anti vibration mounts are available. The method chosen is the responsibility of the installer.
Check that the fan details on the rating plate correspond with the supply voltage and frequency. Motors up to 4.0 Kw are designed for Direct on-line starting. Motor overloads should be set to the full load current on the fan rating label. Supply fuses should be H.R.C. type.
The single phase rotational direction is set at works and should NOT be altered. For 3 phase units check that rotation is correct, if not interchange two phases. [Refer to rotation arrows on outside of fan case]. Equipment should be run for approximately 30 minutes to ensure correct operation. If a fault occures, switch off. DO NOT restart until fault has been rectified.
Electrically isolate before commencing work. Remove fan unit from system. Carefully clean rotating parts and check for damage and security of components. The motor is fitted with sealed for life bearings and does not require any further lubrication. Refit fan unit into system.
