The unique and new blade geometry in this square, duct mounted, mixed flow fan offers increased airflow with smaller diameters.

Easy Installation
Lightweight construction with Ductmate flanges allowing easy installation.

Efficient Performance
High volume flow rates, high efficiency, low acoustic emissions due to special three-dimensional blade geometry with diagonal air discharge, reduced rotational tone.

Controllability
A range of transformer voltage controllers can be used to provide five speed step control of single phase or three phase motors.

Energy saving
Backward-curved, aerofoil section blades provide high volume flow rates and high efficiencies.

Construction
Manufactured using pre-galvanised sheet steel suitably stiffened. Casings incorporate Ductmate flange connections at each end. Motor supports are constructed from steel sheet, hot-dip galvanised to BS EN ISO 1461:2009 after manufacture and have an aerodynamic profile.

Motor
The motor contains sealed for life bearings and have a Thermal Class of to THCL 130 or 155 dependent on size. All motors are suitable for use in ambient air conditions up to +60°C.

Impeller
Made from high-performance composite material with 7 backward-curved, aerofoil section blades.

Typical Applications:
• Kitchen Canopies
• Restaurants
• Lift Motor Rooms
• General HVAC installations

Warranty
Each SMB has a 12 month warranty.
