Air Receiver / Air Compressor Thorough Examination
Air Receivers Within Industry
Air receivers are pressure vessels designed to store compressed air and maintain a stable and reliable supply within compressed air systems. They act as a buffer between the air compressor and the equipment using the air, helping to smooth out pressure fluctuations and reduce sudden demand on the compressor. By storing compressed air, air receivers improve system efficiency, reduce energy consumption, and extend the lifespan of compressors and associated components.
One important function of an air receiver is moisture separation. As compressed air cools within the receiver, water vapour condenses and can be drained from the system. This helps protect downstream equipment from corrosion, damage, and contamination. Air receivers also contribute to safer system operation by allowing pressure relief valves and monitoring devices to operate effectively, ensuring pressure remains within safe limits.
Air receivers are used across a wide range of industries where compressed air is essential. In manufacturing and engineering, they support pneumatic tools, automated production lines, and machinery control systems. Construction sites use air receivers to provide a steady air supply for power tools such as drills, breakers, and nail guns. In automotive and aerospace industries, they are critical for assembly processes, painting, and testing operations.
Other key industries that rely on air receivers include food and beverage processing, pharmaceuticals, chemical production, and energy generation. In these sectors, compressed air is often used for packaging, conveying, process control, and instrumentation. Overall, air receivers play a vital role in ensuring compressed air systems operate efficiently, safely, and reliably across many industrial applications.
What’s Covered During Your SEIS Thorough & In Service Examination.
A PSSR (Pressure System Safety Regulations 2000) Thorough and In Service Examination of an air receiver is a legally required examination to ensure the vessel is suitable for further service, and safe to used as part of the pressure system. If the vessel has a pressure x volume product greater than 250 bar/litres, and a relevant fluid is present within the system, or the vessel holds steam at any pressure, a written scheme of examination must be drawn up and certified. The competent person must carry out the examination in line with the written scheme of examination. Below is a details description of what is typically covered during a Thorough and In Service Examination;
 General Examination
Verification that the vessel complies with it’s manufacturers specifications and current legislation. Check all relevant documentation such as;
- CE/ UKCA conformity documents.
- Maintenance records.
- Previous hydro-static test pressure certificates.
- Previous reports of thorough examination.
- The written scheme of examination.
- Confirmation of all vessel markings (serial number, safe operating limit, design code, vessel volume etc).
 Structural Integrity
- Base of the vessel check supporting feet and ensure vessel is securely affixed.
- Vibration dampening mountings ensure suitability and that they’re not damaged or perished.
- Vessel shell check for no mechanical damage, erosion or excessive corrosion.
- Guarding check the integrity of any guarding covering any moving parts.
- Mounting of system protective devices check for correct fitment and security.
- End caps remove from the vessel, check the securing threads and integrity of the end caps.
- Internal and external examination of the vessel check for any water build up, corrosion, emulsified oil, pitting or wastage.
 Auxiliary Components
- Air lines and hoses check any hoses and air lines associated with the vessel.
- Auto-drain valve check suitability, security and correct fitment.
- Isolation valve(s)Â check suitability, security and correct fitment.
- Drain valve check suitability, security and correct fitment.
- Compressor unit and guarding (if fitted) check suitability, security, drive belts and correct fitment.
 Electrical System
- Electrical isolator switch check suitability and functionality.
- Pressure switch or pressure cut out check functionality during working examination.
 System Protective Devices
- Pressure gauge remove from vessel, check the threads, the gauge face, check for damage and test for calibration.
- Safety valve remove from vessel, check the threads, the valve face, check for damage and test for calibration.
 In Service Examination And Functional Testing
- Allow system pressure to build and ensure the pressure cut out functions correctly.
- Pressure gauge reads correct and gives a smooth and accurate reading throughout its range.
- Safety valve is free to lift by hand at system operating pressure.
 Supplementary Tests
The competent person may use any, or all of the following supplementary tests to supplement their examination.
- Hydro-static pressure test.
- Ultrasonic thickness readings.
- non-destructive testing (NDT) by means of ultrasonic flaw detection, radiographic, magnetic particle or dye penetrant.
Common Defects:
- Manufacturers name plate illegible or missing.
- Pressure gauge damaged or out of calibration.
- Safety valve damaged or out of calibration.
 Documentation and Reporting
After the inspection, the competent person will issue a PSSR Thorough Examination Report. This must include:
- Date of the examination
- Details of the equipment inspected
- Findings, including any defects
- Recommendations or required actions
- Date of next examination due
- Statement on whether the equipment is safe to continue using
If any serious defects are found that pose immediate danger, they must be reported to the duty holder and the enforcing authority (e.g., HSE) immediately.
 Summary
An air receiver PSSR inspection ensures that your pressure systems are safe, compliant, and fit for use. It helps prevent accidents caused by damaged vessels, poor equipment practices and ineffective system protective devices. While it does not replace regular maintenance, PUWER and PSSR inspections are a crucial legal requirement for keeping pressure safe and avoiding costly breakdowns or incidents.
Why Air Receiver Thorough Examinations Matter For You & Your Business.Â
Why PSSR2000 Thorough & In Service Examinations Matter
PSSR2000 thorough & in service examinations are a legal requirement in the UK for all pressure systems used at work and must be carried out in line with their written scheme of examination, and for good reason. These inspections ensure that pressure systems and their equipment, such as air receivers, pressure vessels, steam boilers, and other vessels containing a relevant fluid are safe to use, and fit for purpose. The nature of pressure systems and their associated vessels means that equipment failure can lead to catastrophic consequences, including serious injury, fatalities, and significant damage to property. By carrying out regular, scheduled thorough and in service examinations by a competent person, businesses can identify failure mechanisms, structural damage, or faulty system protective devices before they result in an incident.
Pros of Getting a Thorough and Working Examination in line with PSSR2000
Legal Compliance and Risk Reduction: The most obvious advantage is staying compliant with health and safety law. Compliance avoids potential legal action, fines, or even prosecution. More importantly, it drastically reduces the risk of workplace accidents caused by lifting equipment failure.
Improved Safety Culture: Regular inspections foster a proactive safety culture within the organisation. Employees are more likely to trust equipment and feel safe in their work environment when they know thorough checks are in place.
 Extended Equipment Lifespan: Regularly maintained and inspected equipment typically lasts longer. Examinations can identify early signs of damage or fatigue, allowing for preventative maintenance that avoids costly replacements or repairs.
 Insurance and Liability Protection: Insurers may require evidence of PSSR compliance in the event of an incident. Without valid inspection records, insurance claims could be denied or reduced, leaving the business liable for damages.
 Operational Efficiency: Detecting potential issues before they lead to equipment failure helps prevent unscheduled downtime. This keeps operations running smoothly and avoids the knock-on effects of delayed projects or interrupted workflows.
Cons of Failing to Carry Out PSSR Thorough and Working Examinations
 Legal and Financial Consequences: Failing to comply with PSSR can result in enforcement action from the Health and Safety Executive (HSE), including improvement notices, prohibition notices, fines, or even prosecution. Legal battles and associated costs can be financially crippling.
 Increased Risk of Accidents: Equipment that hasn’t been thoroughly examined is far more likely to fail. Such failures can lead to injuries or fatalities, particularly in high-risk environments like construction or manufacturing. Beyond the human cost, the reputational damage to a business can be severe and long-lasting.
 Higher Repair and Replacement Costs: Neglecting inspections can allow minor issues to develop into major faults. These may require costly emergency repairs or complete equipment replacement, expenses that could have been avoided through routine examinations.
 Loss of Business and Clients: Clients often expect their contractors or suppliers to uphold strict safety standards. A failure to meet legal obligations like PSSR can result in lost contracts or blacklisting from future work, especially in regulated industries.
 Increased Insurance Premiums or Invalidated Coverage: As mentioned, insurers may increase premiums or deny coverage entirely if a business can't provide evidence of up-to-date PSSR compliance, placing a heavier financial burden on operations.
PSSR thorough and in service examinations aren’t just a box-ticking exercise - they are an essential component of a responsible, safety-first approach to using pressure systems. The benefits of compliance are wide-ranging, from protecting human life to reducing costs and maintaining operational integrity. Conversely, the risks of neglecting these inspections can be devastating on multiple levels.
