SLC400/4-3AC – Long Cased Axial Flow Fan – Elta

SLC400/4-3AC – Long Cased Axial Flow Fan – Elta

A true industry workhorse, this extensive range offers superb performance characteristics, combined with strength, durability and corrosion resistance for a longer life.

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.

Suitable for external mounting as standard.

The Elta drive 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.

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 ℃. 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 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.

Speed control shall be via stepped Transformer or Elta drive VSD, dependant on model. Elta drive VSD IP20 or Switched IP66 shall provide precise motor control and energy savings. The Elta drive 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.
