PFD OH

roof

Materiály:

PFD OH  are chemically resistant roof fans with horizontal air discharge. The fans of this series are dedicated to all branches of industry where there is a chemically aggressive environment, high humidity and light dustiness with an aggressive medium. They are used in the following facilities: sewage treatment plants, industrial washing plants, chemical industry plants; mushroom farms, fertilizer storage facilities, food industry enterprises.

What distinguishes PFD OH fans?

One of the most common causes of damage to fans operating in chemically aggressive environments is mechanical damage due to corrosion. The PFD OH fans feature double anti-corrosion protection. All elements in contact with the pumped medium are made of acid-resistant steel with an additional polyester powder coating. In addition, the surface of the rotor blade has been covered with a smooth anti-electrostatic coating, thanks to which dirt settles on the rotor to a lesser extent.

High-efficiency impeller guarantees economic operation.

The fans of the PFD OH series have a radial impeller with backward curved blades. The rotor blades and discs are made of acid-resistant steel and joined by welding (in light clean air fans, the blades are usually welded or pressed to the support disc). The PFD OH fan impeller is distinguished by very good flow parameters with low noise emission (models with low-speed and medium-speed motors). PFD OH fans are also available in a high-pressure version (high-speed motors), thanks to which they can work with local exhausts, e.g. as fans for fume cupboards or fans for extraction arms.

Easy assembly and cleaning.

The fan is equipped with a round mounting flange for mounting on B/I and B/II type roof bases. Thanks to the use of a flange, the fan can be easily removed from the installation for service or cleaning. The air outlet has been covered with a special protective mesh, which protects against rodents and birds and at the same time allows easy cleaning of the rotor blades, e.g. washing with a pressure washer.

Simple and accurate controls.

All PFD OH fans are designed for continuous operation. They can pump air with a constant temperature up to 60 degrees Celsius. Fans can also be made for higher temperatures up to 150 degrees Celsius. All PFD OH fans are designed for very precise speed control with frequency converters. For users who do not require precise regulation, some PFD OH models have been adapted for simple and very effective voltage regulation with transformer regulators. (medium and low speed models with single-phase motors).
