CVAC ATEX – ATEX-certified vacuum units for central vacuum systems of all sizes

DU-PUY centralized industrial suction systems enable the suction of solid or dusty material under hazardous conditions. Available with ATEX certification, they can vacuum material over large distances or in several places simultaneously, thanks to modular turbines and piping.
Our ATEX-certified suction units for centralized suction systems are distinguished by different features and functions including remote local on/off and safety systems to protect the turbine, such as the limiting valve.

DU-PUY central vacuum cleaners are declined in three versions: from 4 to 25 kW.
The configuration of the production plant is decisive in the design of the vacuum system. In fact, each suction system is designed and adapted according to the specific size and characteristics of the area involved as well as the required suction performance.
We will study together how to comprehensively respond to your needs to ensure productive efficiency over the long term.

Suction is provided by a large side channel blower type suction unit, with direct coupling between the fan and the crankshaft. Since it has no transmission systems, it does not require any ordinary maintenance and is suitable for prolonged continuous service. It is therefore completely maintenance-free and suitable for 24/7 service. Provides exceptional suction performance for working in ATEX certified areas. A safety switch stops the engine in case of overheating. The control board is housed within a metal enclosure, securely positioned at the rear, and includes two independent ON and OFF switches, a safety emergency stop button and a star-delta motor starter. A vacuum indicator allows you to constantly monitor the suction performance and detect any blockages in the filter. A pressure relief valve protects the engine from overheating in the event of a clogged filter or other blockages in the intake system; a diffusing filter reduces the speed and noise of the air at the exhaust.
