Features & Benefits

Higher performance

Adjustable pitch impellers mean the pitch angle of the impeller can be adjusted on site (within limits) if a commissioning problem were to occur.

Ease of installation

The centrally mounted motor is wired via a flexible weatherproofed cable system to an externally located IP55 protected terminal box.


All motors are fitted with integral ‘Thermal overload protection’ preventing the motor from overheating.

Material strength

Revolution SLC axial fans have a robust, heavy duty construction for added strength and durability. Fan casings are heavy gauge, sheet steel, roll formed and welded and hot dipped galvanised after fabrication to BS 729.

Quality impellers

Adjustable pitch aerofoil section impellers with blades made from high quality pressure die cast aluminium. Hubs are pressure die cast aluminium.

Cost effective

Fully speed controllable fans which means flexibility in performance.

Quality assurance

All units are designed and manufactured with procedures as defined in BS EN ISO 9001: 2008.


The all metal fan casing provides a long lasting and robust construction. The units have been constructed from a single sheet of steel, with both motor and axial impeller mounted within the length of the unit casing. All casing parts are heavy gauge mild steel sheet, roll formed and welded for added strength and durability, hot dip galvanised to BS EN ISO 1461:2009 after fabrication and drilled to BS ISO 6580:2005 The fans are suitable for external mounting as standard.


Motors are to be foot mounted totally enclosed metric type to IP55, with sealed for life bearings, standard industrial paint finish and Class F insulation to EN 60034-5, suitable for operating temperatures up to +54°C. Motors are to be wired via a weatherproofed cable to an IP55 protected terminal box mounted on the outside of the unit casing.


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 9001:2008. All SLC units are to be tested to ISO 5801:2007 (airside performance) and BS 848 Part 2:1985 (sound performance).
