What are Process Gas Blower or Atex blowers?


A blower is a rotary, positive displacement type of machine used to move gases or mixture of gas. They can be with Two-lobe or Three-lobe rotors design.

Two parallel rotors with identical profiles rotate in the opposite direction in the blower housing. A set of timing gears keeps the rotors in synchronization.

While rotors are spinning, gas is routed into the housing of the blower. This gas is trapped, transported and evacuated by rotation. There is no internal compression and no mechanical contact (no lubrication). Thus, the fluid carried remains free of oil and impurities.

We talk about a process blower when it is designed with specific seals, materials of construction, or special painting, Atex compliance for hazardous areas.

Generally it is used in a complex process or particular conditions as potentially explosive atmospheres.

Benefits Of Positive Displacement Blowers

By their principle, it is a volumetric machine, offering numerous advantages and particularly for process duties:

  • volumetric efficiency;
  • constant massive flow (kg/h);
  • oil-free conveying, 
  • constant air flow, 
  • robust, 
  • without internal compression, 
  • reliable and high performance, 
  • simple operation, 
  • widely used, 
  • belt or direct coupling possibilities, 
  • large volume of flow possible,
  • Cooled by ambient air,
  • Easy to start.

ATEX certification and compliance possibility

All the category 2 ATEX-compliant blowers have been specially developed to pump/compress a flammable atmosphere, classified as an internal zone 1 or 2, without needing to install protective devices such as flame guards.The blowers have also been designed to function in an exterior flammable environment classified as zone 1 or 2. They are explosion proof. The blowers are certified (according to directive 94/9/CE) as category 2 or 3 equipment according to the European ATEX directive.

The blowers are suitable for pumping/compressing a wide range of flammable gases and vapors.The temperature classification that applies to the category 2 or 3 ATEX-compliant blowers refers to the spontaneous combustion temperature of flammable materials that can be pumped/compressed, or that may be present in the external atmosphere.

Process Gas Blower packages

Hibon systems custom packages are designed to meet customer specifications and international codes and standards.

We offer you the know-how to evaluate and produce custom packages.So, the packages can be personalized.
