- Powerful, ideal for high pressures
- Rigid galvanised steel frame construction for internal or external use
- Motors fitted with thermal contact switch preventing overloading
- Speed controllable
- Wide range of models and easy to install
The square cased mixed flow range of fans consists of 9 duty sizes with a maximum flow rate of 3.75 m3/s. The units are manufactured from galvanised sheet steel to BS. 2989. 1982. The fan is designed to operate in atmospheres up to 95% RH and ambient temperatures up to 70ºC
Always handle the units carefully to avoid damage and distortion. Care must be taken to ensure that any slings used for hoisting do not pass through the impeller.
Installation must be completed by competent persons, in accordance with good industry practice and should conform to all governing and
statutory bodies i.e. IEE, CIBSE, COHSE etc. The units can be installed at any angle and are suitable for internal or external use. The fans are designed to be bolted into proprietary ductwork and 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 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 units incorporate a
terminal box on the casing exterior. Units for external use require weatherproof conduit and glands.
Start up Procedure
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. Equipment should be run for approximately 30 minutes to ensure correct operation. If a fault occurs, switch off. Do NOT restart until fault has been rectified.
Electrically isolate before commencing work. The first maintenance should be carried out three months after commissioning. Inspect and clean the impeller and motor assembly with care. The motors are fitted with sealed-for-life bearings and do not require any further lubrication.
One Year Warranty
The 1 year warranty starts from the day of delivery and includes parts and labour for the first year. This warranty is conditional on maintenance being carried out after the first 3 months.
