Specification

Casing

The all metal fan casing provides a long lasting and robust construction. The units have been constructed from sheet steel with both motor and impeller mounted within the length of the unit casing. The motor is located out of the airstream in a single entry tunnel into the casing making the unit suitable for temperatures up to +200 ℃. All casing parts are heavy gauge mild steel sheet, roll formed and welded, then hot dip galvanised to BS EN ISO 1461:2009 after fabrication.

Motors

Motors are to be foot mounted totally enclosed metric type to IP55, with sealed for life bearings, standard industrial paint finish and Class H insulation to EN 60034-5.

Impellers

Adjustable pitch aerofoil impellers are provided with blades made from high quality pressure die cast aluminium (LM6), natural finish. Impellers are factory set at an angle to provide maximum performance. The hubs are manufactured from die cast aluminium alloy (LM24). Assembled impellers are to be dynamically balanced to ISO 14694 Grade G6.3.

Quality Management

Units are to be designed and manufactured with procedures as defined in BS EN ISO 9001. All Biflow SB (CYL) units are to be tested to ISO 5801 (airside performance) and BS 848 Part 2 (sound performance).
