Max Airflow: 4896 m3/hr
Power consumption: 318W

Featuring our high efficiency Series 1 impeller, the Compact SCD makes light work of handling large volumes of air against low resistance. The fan design, construction and finish provide a strong, durable and weatherproofed range.

Easy Installation
Fans are supplied with a fitted IP55 terminal box, which allows the fan to be positioned conveniently to incoming electrical inputs.

Efficient
Performance Impellers are adjustable pitch aerofoil with blades made from high quality GRP. Combined with increased blade chord and twist, we have achieved 7% higher efficiency, reducing overall energy consumption. Increased blade root reduces stress levels making our range of impellers ideal for arduous fan applications.

Corrosion Resistance
Specially treated against corrosion, powder coated with polyester epoxy paint in pastel beige (RAL 7032).

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 speeds can provide significant cost savings through lower energy consumption.

Warranty
Each SCD has a 12 month warranty.

Construction
Constructed from mild steel and suitably treated to ensure full corrosion protection, with both motors and axial impellers mounted within the length of the unit casing. All casing parts have a powder coated polyester epoxy paint finish in pastel beige (RAL 7032).

Motor
Three phase multi-voltage motors are wound for either (Delta) 230V/3Ph/50Hz or (Star) 400V/3Ph/50Hz connection, suitable for speed control up to 50°C when used with the Eltadrive VSD range of frequency inverter controls.

Impeller
Increased twist aerofoil impeller provides improved efficiency and acoustics suitable for higher stress applications.
