Type WPK
The basic purpose of WPK fans is to ensure the main ventilation in mines. They boast a special centrifugal design that ensures a silent and cost-effective operation. A WPK fan has a 1-side exhausting impeller, which also adds to the power efficiency of the fans at peak output times and ensures a long-lasting, failure-proof operation.
The power efficiency of WPK fans helps protect the main fan motor from being overloaded if plugged to the wrong electric network.
WPK fans are easy to assemble and they can operate reversibly, if necessary, thanks to the in-built system of flaps and air-supplying ducts.
WPK fans are designed to operate in an open space. However, the rest of the equipment including the motor, the control system and the control-measuring tool, must be installedinside a building.
