Features & Benefits
The inherent aerodynamic benefits of good mixed flow impeller design provide marked advantages over axial and centrifugal air performance characteristics.
Quality impeller design.
Aluminium spinnings and pressings in a natural finish, together with steel hubs which are suitably zinc plated and dynamically balanced to Grade G6.3 for maximum efficiency.
Installer friendly simplicity.
All motors are pre-wired to an integral IP55 terminal box so they are ready for customer installation.
All units are supplied with an inspection hole which means the correct rotation of the impeller can be checked for ease of commissioning and general maintenance checks.
The unique design of Multiflow SMC fans enables the required performance to be attained from a smaller fan size than is normally achievable with typical conical style, fixed blade mixed flow fans.
Mixed flow “non-stall” airflow properties and a non-overloading absorbed power curve allow a wide range of operating performance to be achieved.
Multiflow SMC mixed flow fans have a long lasting, robust casing design for added strength and durability. Casings are manufactured from heavy gauge steel, roll formed and welded, then hot dipped galvanised to BS 729 after fabrication. All the motor supports are hot dipped galvanised to BS 729 after manufacture.

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 motors and impellers mounted within the length of the unit casing. All casing parts are heavy gauge mild steel sheet, roll formed and welded, then hot dip galvanised to BS EN ISO 1461:2009 after fabrication.
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 +50°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 mixed flow impellers shall be provided with the blade angles set to meet the required duty. The impeller construction shall comprise of aluminium spinnings and pressings in natural finish, together with steel hub assemblies, suitably zinc plated. Assembled impellers are to be dynamically balanced to ISO 14694 Grade G6.3.
Units are to be designed and manufactured with procedures as defined in BS EN ISO 9001:2008. All SMC units are to be tested to ISO 5801:2007 (airside performance) and BS 848 Part 2:1985 (sound performance).
Typical ApplicationsWhere higher pressure developments are required, such as:
- Kitchen Canopies
- Lift Motor Rooms
- General HVAC installations
