These centrifugal backward curved fans are available in 2 models, 190mm and 220mm diameter, incorporating the highly efficient motor rotor. Applications include mini roof units, inline centrifugal fans, range hoods and others where pressure is a consideration.
The ZO Series in line ducted centrifugal fan provides a high performance supply or exhaust system where a small or medium volume of air is required to be moved against a medium to high static pressure to and from enclosed spaces.
Stocked in 400mm 450mm and 560mm diameters these runners can be incorporated in roof extract units or SISW centrifugal fans suitable for air movement applications where higher pressure development is required.
Our low-profile roof extract units are available in a range of sizes from 150mm to 760mm providing extract capacity from 300 to 8000 cubic feet per minute. Units are available incorporating both axial and centrifugal fans.
With a body and wind cone made of 6mm fiberglass, aluminium shutters, radial mounted motors, prewired on board IP66 isolator and poly 760mm impeller these fans are ideal for heat, steam and general roof extract applications. Manufactured unchanged since 1986 these fans have a proven history of reliability and longevity even in arduous service applications.
A compact, inexpensive and flexible in line filter suitable for new installations and retrofitting into existing ducted systems. Available with either washable EU3 or disposable EU5 filter bag the ILF200 will comfortably handle air volumes up to 200 litres per second with minimal pressure loss.
