💰 A LOW PURCHASE PRICE CAN BECOME AN EXPENSIVE BUSINESS DECISION
Before buying a new, used or imported compressor, check the pressure equipment compliance evidence.
If equipment does not meet applicable South African requirements, your purchase could bring unexpected costs:
• Delayed commissioning.
• Additional technical assessments.
• Remedial work or replacement.
• Temporary compressor hire.
• Production interruptions and missed customer commitments.
PER places duties on importers and suppliers, while users also have responsibilities. SANS 347 provides the categorisation and conformity assessment framework.
✅ Before committing, request:
• Traceable identification for the separator vessel and air receiver.
• Applicable manufacturing and conformity documents.
• Inspection, test and repair history for used equipment.
• Confirmation of commissioning requirements and AIA involvement where applicable.
Equipment age, category and legally applicable exceptions must be considered. Appearance and operating condition alone cannot establish conformity.
Make compliance evidence part of your buying decision—not an expense discovered after delivery.

📅 SERVICED DOES NOT MEAN STATUTORILY INSPECTED
Your compressor may have fresh oil and new filters while its pressure vessel inspections are overdue.
Routine maintenance and statutory inspections serve different purposes.
PER Regulation 11 generally requires applicable pressure vessels to undergo inspections and hydraulic testing at intervals not exceeding 36 months, subject to category-specific provisions and approved alternatives.
⚠️ Why does this matter to your business?
An unplanned withdrawal from service can mean idle staff, emergency hire, missed deadlines and overtime to recover lost production.
Where an inspection identifies a defect that endangers people, PER requires use to cease until the prescribed corrective requirements are satisfied.
✅ Confirm:
• Which requirements apply to each vessel.
• The last inspection and test dates.
• The next due dates and any written approvals.
• Who is responsible for arranging the work.
Include both the internal separator vessel and external air receiver in your planning.
Schedule compliance work before it becomes an urgent production problem.

⚠️ HIDDEN INSIDE. STILL UNDER PRESSURE.
A compliant external air receiver does not establish compliance of the separator vessel inside your screw compressor.
The internal air/oil separator vessel also needs attention under South Africa’s Pressure Equipment Regulations and applicable SANS 347 requirements.
🚨 The business impact can extend beyond one component:
• Taking the affected compressor out of service can interrupt your compressed-air supply.
• Production delays can affect customer deliveries.
• Emergency compressor hire can add unexpected costs.
• Remedial work—or replacement where conformity cannot be established—can strain your budget.
• A pressure containment failure can injure people and damage surrounding equipment.
✅ Ask for the separator vessel’s identification, applicable conformity documents and inspection history. Have the requirements verified by an Approved Inspection Authority (AIA) where applicable.
Replacing the separator filter element does not establish compliance of the vessel containing it.
Check inside the cabinet before a hidden compliance problem becomes an operational problem.

📁 CAN YOU PROVE YOUR PRESSURE VESSEL COMPLIES?
Missing compliance documents can become a costly business problem—especially when equipment needs to be commissioned, inspected, repaired or sold.
PER Regulation 14 requires users to retain applicable manufacturing certification and records of inspections, tests, repairs and modifications.
⚠️ What could this mean for your business?
• Delays while missing documentation is recovered or verified.
• Additional assessment costs.
• Disrupted production if equipment cannot lawfully remain in service.
• Potential prosecution for specified PER breaches, with fines or imprisonment upon conviction.
✅ Check your records for BOTH the compressor’s internal air/oil separator vessel and the external air receiver. Make sure the documents match the equipment’s identification.
SANS 347 determines the applicable categorisation and conformity assessment requirements. Requirements depend on the equipment and relevant exceptions.
A service invoice alone does not establish pressure vessel compliance.

⚠️ IS YOUR COMPRESSED-AIR EQUIPMENT LEGALLY COMPLIANT?

Pressure vessel compliance goes beyond the air receiver standing next to your compressor.

The internal air/oil separator vessel in an oil-injected screw compressor is also pressure equipment. Being inside the compressor cabinet does not automatically exempt it from South African requirements.

South Africa’s Pressure Equipment Regulations (PER), under the Occupational Health and Safety Act, govern applicable pressure equipment. SANS 347 sets out its categorisation and conformity assessment requirements.

✅ What should your business check?
• The requirements applicable to BOTH the internal separator vessel and external air receiver.
• Correct vessel identification and data plates.
• Manufacturer’s certification and conformity documentation, with Approved Inspection Authority (AIA) verification where required.
• Suitable pressure and safety accessories.
• Required commissioning inspections, periodic inspections and tests, with records retained.

PER Regulation 11 generally requires applicable pressure vessels to undergo inspections and hydraulic testing at intervals not exceeding 36 months. Category-specific provisions, exclusions and approved alternatives must be considered.

🚨 What can non-compliance mean?
• Serious injury and property damage if equipment fails.
• Equipment being taken out of service and production interrupted.
• Costly investigations, remedial work or replacement.
• Prosecution, with fines or imprisonment upon conviction for specified offences.

Buying a compressor does not remove your responsibilities as the user. Routine servicing alone does not establish pressure vessel compliance.

Before purchasing—or continuing to operate equipment with uncertain compliance—request the documentation and have the requirements verified by an AIA where applicable.

🔧 PLAN YOUR MAINTENANCE BEFORE PRODUCTION PEAKS

When orders increase and deadlines tighten, an unexpected compressor stoppage can disrupt your entire production schedule.

Planning maintenance ahead of your busiest period gives you time to address wear, arrange parts and book servicing during a convenient shutdown—helping reduce unplanned interruptions when reliable compressed air matters most.

Before the rush:

✅ Review service intervals against operating hours and manufacturer recommendations.
✅ Have filters, lubricants, coolers and other service components checked.
✅ Include dryers, drains and inline filters in the maintenance plan.
✅ Investigate leaks, unusual noise, high temperatures or pressure changes early.
✅ Test your standby compressor and confirm backup arrangements.

A scheduled service window is easier to manage than an unexpected production stoppage.

Contact Airstream Compressors SA to plan your next service.

🔧 IS YOUR BACKUP AIR READY?

A standby compressor can spend weeks waiting for its moment—but low running hours don’t guarantee it’s ready to perform. Leaks, overdue servicing or control faults can go unnoticed until your main compressor stops.

Keep your backup ready with regular checks:

✅ Test under load: Confirm it builds and maintains the required pressure while supplying air—not simply that it starts.

✅ Check the changeover: Have your technician verify that the standby unit takes over as intended, including automatic start controls where fitted.

✅ Monitor performance: Watch for unusual noise, vibration, temperature changes, leaks and fault messages.

✅ Keep maintenance current: Follow the manufacturer’s running-hour AND calendar-based service intervals. Include drains, dryers and filters in your checks.

✅ Record and resolve: Log each test and fix problems before the next emergency.

Arrange a testing schedule with your compressor service team that suits your equipment and operation.

Test today. Be ready when it matters.

🏭 Planning a factory expansion? Don’t forget your compressed air!

New production lines, machinery and workstations can place extra demand on your compressed-air system. Planning ahead can help you avoid pressure problems, interruptions and costly changes later.

Before your expansion gets underway, consider these four areas:

💨 Future air flow: How much air will the new equipment need, and will several machines operate at the same time? Check your existing compressor capacity against expected demand.

🔧 Pipework: Can your distribution network carry the additional flow to the new equipment without excessive pressure drop?

🛢️ Air storage: Is your receiver capacity suitable for demand peaks and stable system pressure?

💧 Air treatment: Can your dryers and filters handle the increased flow and provide the air quality your new processes require?

Looking at the complete system together helps you plan an installation that supports your operation as it grows.

🔄 Are your compressors working together—or working against each other?

When multiple compressors supply the same air system, uncoordinated pressure settings can cause unnecessary loading and unloading, pressure fluctuations and wasted energy.

Compressor sequencing gives each machine a clear role:

✅ Lead compressor: Responds first to air demand.
✅ Lag compressor: Adds capacity when demand increases beyond what the lead machine can supply.
✅ Coordinated pressure settings: Carefully matched load/unload settings—or a compatible central controller—help machines respond in the correct order. As demand falls, surplus capacity is taken out of service in a controlled way.

Where suitable, the lead role can also rotate between machines to balance operating hours and support maintenance planning.

The result? A more stable air supply, less unnecessary cycling and more efficient operation.

Settings should suit your compressor types, air demand and required operating pressure.
