Farm building fan WPM series

for air circulationcentrifugal

MEDIUM PRESSURE WPM -high efficiency impellers (consuming less power) -wide range of centrifugal impellers ensuring availability in systems with various motor powers and allowing high design flexibility -rigid, durable casings that guarantee the long-term operation of the fans without any failures -availability of motors with 3000, 1500, 1000 rpm -availability in all instalation position -drainage for installation position which require it -carefully selected solutions in order to ensure easy mounting and transportation of the fan to its destination. Apart from our standard production, we manufacture fans in high-temperature-resistant or explosion-proof versions, in soundproof or thermal casings, in mobile versions, with cage guards etc FAN HOUSING Each housing has an external spiral outline specifically designed by our engineers to optimise the flow. A standard fan housing is made of welded steel. It is protected against corrosion by paint or galvanisation. Paint coatings protecting the housing are available in the full RAL range of colours. MOTOR Asynchronous, in a closed casing made of die-cast aluminium or iron, equipped with maintenance-free bearings, 1 (230V) or 3 (3x400V) phase. Power supply frequency: 50 Hz. Insulation class: F or H. IP 55 protection level. Operating temperature: -20 to +40 °C. Optional possibility of operation with a frequency inverter and a higher protection level of IP56 or IP66. IMPELLER Impellers of the centrifugal fans manufactured by Planetfan are welded. The types of steel used for their production ensure reliability and long-term operation. The structure has been developed to achieve top efficiency.
