Medium Pressure Fans:
These are employed for air containing dust or particles, fibers, flakes and having higher temperatures than ambient. Usually offered in Single inlet styled fans are moderately efficient and useful for dust collection, Drafting and exhaust/pollution control duties. Impellers are Radial tipped or Backward inclined bladed type having flat of Airfoil designs, with closed or open constructions. The P-V characteristics is flatter and blowers are designed for long hard duties.
- Air flow (capacity) range : 170 CMH to 102000 CMH
- Static Pressure Range : 150 mm WC to 600 mm WC
- RPM variation : 800 to 3000
- Inlet/Outlet Velocity : Accurately design to suit the application and noise levels
- Noise at 1 m distance : Less than 85 Db
High Pressure Fans:
Employed for medium to high pressure blowing jet duties in processing, combustion or agitation, these blower are offered in single or two stage constructions. These can also be applied to partial vacuum duty negative suction requirements. Impellers are radial or radial tipped. Usually running at higher revolutions and having high tip speeds. Efficiencies are relatively lower.
The P-V characteristics is flat over a wide range of volumes. Static pressure ranging up to 60o WG and drive style of direct, coupled or v-belt type.
- Air flow (capacity) range : 170 CMH to 10000 CMH
- Static Pressure Range : 600 mm WC to 1000 mm WC
- RPM variation : 2000 to 3000
- Inlet/Outlet Velocity : Accurately design to suit the application and noise levels
- Noise at 1 m distance : Less than 90 Db
