Fans
They don’t mind a rough working environmentWe offer a wide range of fans for use with extraction systems. They meet your highest demands, even under tough operating conditions. In addition, correct design and short delivery times are standard for us.
Our fans are produced by renowned specialists and have outstanding features.
The fans are typically used to convey dirty, greasy, hot (up to + 100° C) and humid air against high resistance in industrial and commercial applications.

Pre-separator systems
Spark extinguishing system to prevent filter firesWith certain dusts from cellulose and metal processing, there is a constant risk of filter fire. If the sensor of this high-performance separator detects sparks being sucked in, the air supply is immediately interrupted to prevent the spark from reaching the inside of the dust extraction system.
The spark extinguishing system consists of coordinated components: Spark detector, evaluation electronics, actual separator. The high-performance separator with its collection container can be installed at any point in the pneumatic transport channel. In the event of an alarm, the control system takes all measures to raise the alarm and switch off machines and fans in stages. The smallest sparks are detected and extinguished using highly sensitive infrared sensors.
The spark extinguishing system complies with VDS guideline 2106.
