SPP Features and Benefits
 

Features & Benefits


Aerodynamic appeal

The inherent aerodynamic benefits of good mixed flow impeller design provides 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.

Material strength.

Multiflow SMB mixed flow fans have a robust casing design for added strength and durability. Casings are manufactured in pre-galvanised sheet steel which is suitably stiffened, with all motor supports hot dipped galvanised to BS 729 after manufacture.

Distinctive

The unique design of Multiflow SMB 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.

Outstanding performance

Mixed flow “non stall” airflow properties and a non overloading absorbed power curve allow a wide range of operating performance to be achieved.
