Air Ejectors for Gas, Vapour & Fumes Venting

Multiple Industrial Process end up generating gases and fumes during operation. In some cases these gases and fumes are toxic or corrosive in nature and are an environmental hazard while in some cases the gases & fumes tend to accumulate and disturb operation.

Hence it is important to collect and vent these gases / fumes appropriately.
But at the same time the venting equipment needs tp overcome the below challenges
• Corrosion due to corrosive vapours coming from the Chemical media
• Should be able to handle solid particles as in some cases the venting gas may contain solid powders.
• Should be able to handle liquid carryover in form of oil mist in case of venting of oil tanks.
• Some of the vapours and fumes may be inflammable so non sparking operation is essential.

Air Ejectors are simple devices that operate on the basis of the jet Venturi principle.
Air Ejectors utilize the energy in compressed air for their operation and can be put to use to create vacuum conditions at their suction inlets. The generated vacuum is used to suck the vented gases, vapours and fumes and transport them to a safe location for disposal.

Air Ejectors designed for venting application have large suction capacities and can suck large amount of gases while consuming relatively less compressed air.

Air ejectors are suited for the gas, vapours and fumes venting because of their inherent characteristics

• Can be manufactured in a large range of materials (Plastics, Stainless Steels, Exotic Materials)– it helps to select the best possible material compatible with the involved vapours and reduces the risk of corrosion
• Air ejectors do not contain any moving parts and have large internal passage areas, hence are not vulnerable to liquid entry or clogging by solid particles.
• As they have no moving parts, maintenance requirements are very less. Also it reduces largely the risk of abrupt breakdowns, helps in maintaining the regular production schedule
• Suitable for inflammable substances as Air Ejector have a non sparking operation.
• Compressed air is a commonly available utility and hence no additional infrastructure is typically required.
