The DU-PUY centralised industrial vacuum cleaner systems allow the suction of solid or dusty material in hazardous conditions. Available with Atex certification, thanks to a power and piping that can both be modulated, they can also vacuum up material over a long distance, or in several places simultaneously. 
The Du-Puy Atex certified central vacuum cleaners include as standard several features and functionalities including remote local switch-on and switch-off and safety systems to protect the turbine, such as the limiting valve.
Suction is provided by a large side channel blower type unit, with direct coupling between the fan and the motor shaft and no transmission system.
It is therefore completely maintenance-free, suitable for 24/7 service, very quiet and provides exceptional suction performance for working in Atex certified areas.
A safety switch stops the motor in case of overheating.
The control board is located inside a metal casing, in a safe position at the back, and includes two independent ON and OFF switches, an emergency safety stop button and a star delta motor starter.
A vacuum indicator allows constant monitoring of suction performance and detection of filter clogging.
A pressure relief valve protects the motor from overheating in the event of filter clogging or other blockages in the suction system; a diffuser filter reduces the speed and noise of the exhaust air.

DU-PUY central vacuum cleaners are available in three versions: from 4 to 25 kW.
The configuration of the production plant entirely determines the characteristics of the vacuum cleaner. Each extraction system is designed according to the specific dimensions and characteristics of the area in which it is to be installed, and the suction performance required.
Together we will work out how to meet your needs comprehensively, to ensure long-term production efficiency.
