Features & Benefits
Powerduct SPD 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 powder coated after manufacture.
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.
Quality Impeller Design
Aerodynamically designed backward curved impellers which are constructed from aluminum or galvanised sheet steel and dynamically balanced to quality class G6.3 to maximize efficiency.
Casings incorporate metric flange connections to suit industry standard duct sizes which means they can be installed quicker and easier.
All units are designed and manufactured with procedures as defined in BS EN ISO 9001: 2008.
Ease of installation
All motors are pre-wired to an integral IP55 terminal box on the outside of the casing so they are ready for customer installation.
Full accessory range
Speed controllers, mounting brackets, anti-vibration mounts, flexible connectors and silencers.
