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.

Construction Materials & Manufacturing Codes

To meet your requirement, HIBON blowers are designed in a wide range of materials:

• Cast iron, 
• Cast iron low temperature,
• Carbon steel,
• Stainless steel,
• Nickel coating. 

Rotors

We can offer you trilobe (Three-Lobe) or bilobe (Two-Lobe) rotor design depending on your application.

Specific Seals

Seals are selected according to the applications.

Their variety allows answering numerous applications on:

• neutral gases,
• aggressive gases
• hazardous gases,
• flammable gases.

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. 

It could include:

• drives,
• silencers,
• heat exchangers, 
• acoustic enclosures, 
• full instrumentation, 
• control gear, 
• valves and complete piping systems, 
• thermal insulation on casing and on silencer. 

There are also some package versions in direct coupling for using a VSD driver.

Quality control

Hibon is ISO 9001 certified.

Hibon applies to the process gas blowers a quality assurance plan. This level of requirement is stringency applying to all the suppliers of the components used in the final equipment.

HIBON ensures optimum quality through the skill of its employees and the performance of its production equipment.

We supply technical files. They could include specific tests, specific certificates on demand, and certification as ATEX zone 1 or Zone 2, and Gost R.

Flow And Pressure Range of Hibon Process Gas Solutions

The equipment is used in a single configuration, the maximum discharge pressure is 14,5 PSIG (1 bar). Negative pressure attains 50%.

The range of gas blowers produce flow rates of up to 7 800 CFM (13 000 m³/h).

Hibon Case studies are numerous.
