Vertical Air Receivers

A vertical air receiver - sometimes referred to simply as an air receiver tank - is a pressure vessel installed in a compressed-air system to provide a buffer between the compressor and downstream usage. It acts much like a storage “reservoir” of pressurised air, enabling the system to:

• Smooth out pressure fluctuations, especially when demand surges
• Reduce the number of compressor starts and stops (improving efficiency and lifespan)
• Allow condensate to drop out of the system before the air proceeds downstream
• Provide a reserve of air that helps maintain stable pressure during peak use

Because it is oriented vertically, it has a small footprint compared to a horizontal version, making it ideal for plant rooms or workshops with limited floor space.

In effect, you can think of the air receiver like a “battery” for compressed air - it stores energy (air under pressure) ready for use when needed.

This is the standard painted-finish model offering a robust, general-purpose option for industrial compressed air systems.

Key details:

• Working pressure: up to 11 bar (some up to 12 bar) with maximum pressure values around 160–174 psi
• Outlet BSP size ranges from ¾″ to 3″
• Vertical orientation saves floor space, making it suitable for plant rooms, workshops and systems where space is at a premium
• Supplied with a fittings kit for straightforward installation
• Painted finish adds a layer of corrosion protection for general industrial use

Use case:

Ideal for a standard workshop compressed air system where ambient conditions are typical and the receiver doesn’t face severe corrosive or outdoor conditions.

This variant is designed for higher-pressure applications where system pressures exceed standard levels.

Key points:

• Working pressure up to 16 bar (or 15 bar in some models) with maximum pressure values around 232 psi
• Available in capacities from 200 L upwards in the high-pressure range
• Painted finish remains, so suitable where corrosion is moderate but elevated pressure demands exist

Use case:

When your compressor or downstream equipment operates at higher pressures (e.g., heavy-duty industrial uses) and you need a receiver rated accordingly.

This model addresses environments where corrosion resistance is a key concern. The galvanised finish offers superior protection compared to painted steel.

Highlights:

• Working pressure up to 11 or in some cases 12 bar (maximum around 160–174 psi)
• Finish: fully galvanised steel (zinc coating) to stand up to harsher ambient conditions
• Vertical orientation retains the space-saving benefits

Use case:

Ideal for workshops or plant rooms where humidity, external weather exposure or corrosive atmospheres (salt spray, chemical exposure) are present.

For the most demanding situations - high pressure and high corrosion resistance.

Key features:

• Rated up to 16 bar (maximum approx. 232 psi) in a galvanised finish
• Combines heavy-duty pressure capability with galvanised steel protection

Use case:

For industrial plants, offshore or coastal applications, or any compressed air system that must withstand elevated pressures in aggressive environments.

Installing an air receiver is straightforward when planned correctly; here are the key steps and best-practice considerations presented in a clear, professional yet accessible manner:

1. Pre-installation checks

• Verify the receiver’s specification (working pressure, maximum pressure, outlet size) matches your compressor and downstream system requirements
• Ensure you have a suitable location: flat, stable floor or base, appropriate lifting access, and clearance for service (valves, drain, gauge)
• Confirm whichever finish (painted or galvanised) is suitable for the environment (corrosive vs general)
• Ensure pipework and connections (outlet size, BSP/thread type) match the receiver’s provisions

2. Positioning

• Place the receiver in the chosen spot, ensuring it’s level and anchored as required (especially for large sizes)
• Leave sufficient clearance around the vessel for maintenance - drain valve access, safety relief valve, gauge view
• Ensure lifting equipment and rigging is available if the receiver is large/heavy

3. Connections & commissioning

• Connect the receiver outlet to the compressed-air system using appropriate pipework of correct size (as per the receiver’s outlet specification)
• Install a safety relief valve, a pressure gauge, and an automatic drain to the vessel base. These are included in the accompanying receiver kits
• Ensure all connections are pressure-tested (to appropriate test pressure) before connecting to the compressor
• Slowly bring the vessel into service: open the supply line, allow the vessel to fill, check for leaks, and confirm stable pressure build-up

4. Operational checks

• Monitor the system pressure and ensure the receiver holds pressure as expected without undue drop when demand surges
• Regularly drain condensate via the base valve (at least daily, or as per system requirements) - this helps prevent corrosion and downstream water contamination
• Inspect the exterior finish (paint or galvanised) periodically for signs of corrosion or coating damage; early remedial action extends service life
• Check safety relief valve functionality at defined intervals (in line with your maintenance regime and relevant pressure-vessel regulation) to ensure safe operation
