Features and Benefits:

Easy Installation
Motors are wired via a weatherproofed cable to an IP55 protected terminal box mounted on the outside of the unit casing for ease of electrical connection.

Efficient Performance
High efficiency adjustable pitch aerofoil impellers are provided with blades made from high quality pressure die cast aluminium. Increased blade chord and twist provides 7% higher efficiency reducing overall energy consumption. Increased blade root reduces stress levels which make our range of impellers ideal for arduous fan applications.

Corrosion resistance
Suitable for external mounting as standard.

Controllability
The Eltadrive range of inverters has been designed encompassing the latest technology and combining robustness with reliability. Using an inverter to control fans via sensors to reduce fan speed can provide significant cost-savings through lower energy consumption.

Warranty
Each SLC has a 12 month warranty.

Specification:

Casing
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
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 mountedon the outside of the unit casing.

Impellers
Adjustable pitch increased twist 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.

Control
Speed control shall be via stepped Transformer or Eltadrive VSD, dependant on model. Eltadrive VSD IP20 or Switched IP66 shall provide precise motor control and energy savings. The Eltadrive range of inverters have been designed encompassing the latest technology and combining robustness with reliability. Using an inverter to control fans via sensors to reduce fan speed can provide significant cost-savings through lower energy consumption.

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