Dental COMPRESSOR UK GUIDE

When you walk into a clean, modern dental surgery, everything seems in place. The chair is pristine, the light is perfect, the layout is efficient. But step into the back room, and you’ll often find something else entirely a forgotten compressor sitting in a dusty corner, humming along without much thought.

It’s oil-less, sure. Most of them are these days. But does that mean it’s right for the job? That it’s set up properly? That it’s being looked after? Not always.

Oil-less Isn’t Always Enough

We see it all the time. A practice invests in a decent compressor, but installs it in a cramped cupboard with no ventilation. The filters are left unchanged, the dryer is saturated, and the dew point the measure of how dry the air is slowly creeps up without anyone noticing.

Then one day, a handpiece starts rusting. Or the CQC inspector asks about maintenance records. Or a dentist wonders why their new scaler feels sluggish.

It’s easy to assume that once the label says oil-less, the job is done. But in reality, the quality of air your compressor delivers depends on where it’s kept, how it’s maintained, and how well it suits your surgery’s needs.

Think About This: Would You Put Your Server in a Dusty Room?

Your air system is a critical part of your clinical setup. It’s no different to your IT or your sterilisation workflow.

Imagine running your computer network in a mouldy cupboard. Overheating, dust, no airflow. You wouldn’t dream of it.

So why treat your compressor that way?

It’s Not Just Air. It’s Dental Grade Air

Your compressor needs to do more than just push air through pipes. It needs to supply:

• Clean air, free from bacteria and oil residue

• Dry air, with a low dew point

• Consistent flow, especially during busy clinic hours

• Silent or near-silent operation so it doesn’t disturb patients or staff

Some systems do this brilliantly. Brands like Cattani and Dürr are built with these things in mind and that’s what we include in our portfolio at Diamed Engineering.

What You Can Do

Whether you’re setting up a new practice or reviewing an existing one, here’s what we suggest:

• Check where your compressor is located. Is there airflow? Is it clean?

• Look at your service records. Has the dryer been replaced or tested?

• Match the system to your actual usage. One size doesn’t fit all.

• Confirm your compliance. Has your compressor had its Pressure Vessel Inspection (PVI) this year? Are maintenance logs up to date for CQC?

And if you’re not sure where to start simply ask us. At Diamed Engineering, we don’t just sell compressors. We offer a comprehensive service package, including installation, annual servicing, and statutory PVIs, so your equipment stays safe, reliable, and compliant.

A Final Word

Just because something is labelled oil-less doesn’t mean it’s perfect. A well-installed, well-serviced compressor will save you money, protect your equipment, and help you meet the standards your patients and inspectors expect.

At Diamed Engineering, we support practices across the UK , with advice, supply, installation, and compliance services for dental compressors that do more than just tick a box.

If you want help reviewing your setup or are planning a new fit-out, get in touch. Let’s make sure your air is working for you, not against you.

A Note on UK Guidance and Regulations

In the UK, dental practices are expected to follow HTM 02-01 and HTM 2022 standards, which outline the requirements for safe and compliant dental air systems. These cover everything from air quality and dew point control to installation, servicing, and risk assessment.

If you’re not familiar with these documents or would like to double-check your compliance, we recommend reviewing:

👉 NHS HTM 02-01: Medical gas pipeline systems

👉 HTM 2022 (Archived but still referenced for dental air and vacuum systems)

We’re happy to help translate all of this into practical, real-world steps for your practice.
