PRESTUR Medium Pressure Centrifugal Fans
Available in standard and ATEX Construction
Manufacturing Features:
Medium pressure centrifugal fan with direct coupling.
Reinforced housing made of carbon laminated steel with a powder coating polyester resin, RAL 5010, for enhanced corrosion resistance. Finish C3.
Casing fully latched and adjustable.
Self-cleaning turbine and reinforced impeller with high-performance backward (reaction) blades made of carbon laminated steel dynamically balanced to minimise noise and vibrations. Black painting RAL 9005.
Motor with flange (B5), airtight axle.
Double suction flange.
Available in the following guidelines (to be indicated in case of order): LG and RD.
Maximum working temperature in continuous: transported air: 130ºC, ambient: 60ºC.
Squirrel cage standardised asynchronous IEC motor with IP55 protection and class F electrical insulation. Standard voltages 230/400V 50Hz for 3~ motors up to 4kW and 400/690V50Hz for higher powers.
Ideal for Moving Clean or Dusty Air in Medium Pressure Applications
PRESTUR centrifugal fans are designed to be fixed in the double suction flange, with the motor in vertical position. They are suitable for moving clean or dusty air in medium pressure applications including paint booths, food processing, incineration, extraction of smoke and the manufacture and treatment of chemical products.
