PRF-EX Centrifugal Fans

Speed controllable, explosion-proof efficiency

Certified according to ATEX 2014/34/EU
Handles Aggressive Media
Flexible Use

Safety first

PRF-EX fans are designed for challenging environments where explosive atmospheres can occur. Which is why they are tested according to ATEX directive 2014/34/EU – to ensure they’ll perform as intended after installation.

Flexibility

Where dirt, corrosive gases or other problematic elements occur, fans are exposed to particular challenges. Our PRF-EX range were specially developed for such applications in the food, electronics, medical facilities and chemical industries. With the help of robust and carefully selected components, there function reliably in unfavourably conditions.

Modularity

The position of the unit’s antistatic casing, which is made from UV-resistant and watterproof PP or PE, can be easily adapted. This making the PRF suitable for various configurations.

Performance

PRF-EX could be used for temperature classes T1 to T4. Exhaust of potentially explosive gases in Zone 1 and Zone 2, as well as Groups IIA, IIB and hydrogen is also possible.

Features

Construction

Sintered casing made of UV-resistant PP or PE, waterproof. The casing can be easily adjusted through turning it (Standard position is LG270). The pedestal is manufactured of stainless steel, abrasion-resistant lacquered.

Impeller

The PRF-EX fans use single-flow impellers made out of PP or GFK (PRF-EX 500D4 Ex d) with effective blade geometry, dynamically balanced and paired with corresponding IEC Ex db motor.

Motor

Explosion proof motor Ex db with terminal box Ex eb on the motor.

Motor protection

Integrated PTC thermistors, to be connected to a motor protection device.

Control

Speed controllable by frequency converter.

Installation

PRF-EX fans can be stand on floor with mounted pedestal. For preventing vibration to the duct is recommended to use flexible connection.
