In the 39 years that Pressure Tank has been in existence, we have manufactured in excess of 34200 vessels. We currently manufacture in excess of 1000 vessels per year.

Air receivers are used as storage vessels/ tanks, for the pressurized compressed air that is created by an air compressor.

The purpose of an air receiver is to store compressed air, as this reduces the fluctuations arising from changes in load and compressor switching.

An air receiver also compensates for peak demand and helps balance the supply of the compressor with the demand of the system.

 Air receivers act as an air reservoir of compressed air for peak demands.

An added benefit of an air receiver tank is that it helps to remove moisture/water from the compressed air system.

An air receiver also helps minimise pulsation in an air system (especially for reciprocating compressors or a cyclic process downstream)

Air receivers can be manufactured to stand one of two ways-

Vertically – when there are space restrictions, or for bigger air receivers, air receivers stand upright, or

Horizontally – there are generally your smaller air receivers, and the air compressor is then mounted on top of the air receiver via a baseplate/ mounting plate.

Vessels manufactured for the storage of compressed air.

Vessels manufactured for the storage of air under a vacuum.

An air manifold is another form of an air receiver, they can be either vertical or horizontal in orientation.

Air manifolds/buffer tanks are air receivers that can be installed further away from a compressor, close to a specific machine that requires a constant air supply, more than what the compressed air line can provide instantly.

An air manifold (distribution manifold) can also be mobile/ movable- so when onsite you can couple one compressor or a few compressors into it, and then have multiple outlets (feeding many different machines – sandblast pots, air grinders, air drying units, etc).

Compressor tanks are air receivers that are situated next to, or underneath a compressor.

These air receivers store the compressed air, until the air is required from the pipeline.

Once the air is required, the air is discharged – either directly into the pipeline or through compressed air dryers and filters (the air dryers and filter clean the air if contaminants – from oil to dust to fine metal shaving), they also remove moisture (water from the system).

Vacuum receivers are another form of air receiver, however instead of being pressurised with a positive (pushing pressure), they are subject to a vacuum/ negative pressure (sucking pressure).

Vacuum receivers are piped up to a vacuum pump.

Vacuum receiver can also be vertical or horizontal, free standing or have vacuum pumps mounted on top of them.

Vacuum receivers are of critical importance in hospitals.

We build desiccant air dryer vessels and air filter casings for various companies that specialise compressed air quality.

Air dryers and compressed air filter vessels, work together to lower the temperature of the compressed air (helping to cool the air and thereby making it easier to remove water condensate), other than water they also then remove contaminants from the air – from oil to dust to fine metal shaving).

Pressure vessels are vessels or tanks that are designed to store a solid, liquid or a gas under pressure.

The contents of these tanks range from air, to nitrogen gas, to fire suppression powder or foam,/water along with many other substances.

We manufacture fire retardant vessels for reputable fire suppression companies – for both mobile and stationary purposes.

Compressed air/ oil separator vessels are generally built inside the compressor housing/ canopy.

The separator vessels have a removable filter element inside, and this helps to separate the oily from the compressed air.

Sandblast vessels come in various shapes/ configurations and sizes.

The purpose of a sandblasting vessel is for surface preparation before painting or galvanizing, etc can take place.

A sandblast vessel is filled up with the correct media/ sand for the surface preparation required.

The vessel is then sealed off pneumatically, while the compressed air is fed into the blast vessel.

Once the vessel is pressurized, you release the pressure via a remote and pressurized sand is expelled onto the surface you’re cleaning- ie. You’re now sandblasting.

Vaposol tanks are generally installed on a drill rig, and it stores water under pressure.

The pressurised water is released while drilling to reduce the dust made by the drilling process.

VPI tanks and systems are used in armature winding.

Whereby a vacuum/pressure tank is opening, and the armatures are inserted, the tank is then closed.

Various valves are opened and closed, and the vacuum pump is started and sucks resin from the resin storage tank.

Once sufficient resin is in the VPI tank, the valves are closed and the pressure is exerted into the VPI tank, enabling the resin to adhere to the armatures.

Air cannons are air storage pressure vessels that are mounted onto the side of a silo, and when a silo is struggling with media blocking the outlet flow of a silo.

Then the air cannon will be charged with compressed air, once fully charged the air cannon will discharge the pressurised air into the silo and hopefully dislodged the blockage.

Sand transfer vessels are installed in foundries to help with the transportation/ flow of the sand media used in making castings.

The vessel is loaded with sand, sealed off, compressed air inserted and then the bottom valve released, which then forces the sand to where it is required.

Manufacture/ fabricate water purification/ softening vessels.

These include but not limited to – Anioin/ Cation vessels, water filter vessels, carbon filter vessels.

We can supply the various safety fittings required for air receivers- so long as sufficient information is provided.

We supply, but not limited to-

Pressure safety relief valves, Pressure Gauges, reducing sockets, plugs, manual and automatic drain valves and a host of other fittings.

According to the law, it is mandatory for an air receiver to a have a pressure relief valve and a pressure gauge.

The relief valve is generally set at a 10% higher than the working pressure of the system.

It also important to install either a manual or an automatic drain on the receiver tank.
