heavy duty, vertical exchaust
WPV are industrial roof fans with vertical air discharge. The WPV series fans have been created especially for users who need a quiet roof fan to work in difficult conditions. Industrial facilities such as production halls, workshops or large-scale warehouses require very effective ventilation. In such facilities, the air is often polluted with various types of harmful substances (dusts, gases or mists). In this type of installations, an ordinary lightweight fan does not work (frequent component failures, poor flow parameters). The WPV fan has been designed for facilities with such contaminants as: welding dust, harmful gases, exhaust fumes, oil mist or technological slurry from the coolant.
The WPV fan uses an additional motor rain cover directing the air discharge upwards. As a result, the fan emits much less noise to the environment. An additional advantage of this solution is the emission of pollutants upwards, which increases their dispersion. Pollution does not settle directly on the roof.
The WPV series fans have a radial impeller with backward curved blades. The blades and rotor discs are made of steel and joined by welding (in light clean air fans, the blades are usually welded or pressed to the carrier disc). The WPV fan impeller is distinguished by very good flow parameters with low noise emission (models with low-speed and medium-speed motors). WPV fans are also available in a high-pressure version (high-speed motors), thanks to which they can also work with local exhausts, e.g. catering hoods, welding arms or exhaust fumes.
The advantage of WPV type roof fans is their high resistance to weather conditions. The fan is protected against corrosion with polyester (powder painting using the oven method). The engine is covered with a dome that guarantees very good ventilation of the engine and protection against rain.
All WPV fans are designed for continuous operation. They can pump air with a constant temperature up to 40 degrees Celsius. Fans can also be made for higher temperatures up to 100 degrees Celsius. Thanks to this, they will prove themselves as extractors of technological heat from furnaces, smokehouses, as well as supporting the extraction of fumes and exhaust gases. All WPV fans are designed for very precise speed control with frequency converters. For users who do not require precise regulation, some WPV models have been adapted for simple and very effective voltage regulation with transformer regulators. (medium and low speed models with single-phase motors).
