Airmaster Air Compressor Buying Guide 2026

1. About Airmaster — A Trusted UK Brand

Airmaster air compressors have been sold in the United Kingdom since 1989, giving the brand well over three decades of presence in the workshop and trade market. Sold exclusively through Machine Mart — Britain's largest specialist tool retailer, with stores nationwide — the Airmaster range is firmly positioned as a high-value alternative to more expensive professional brands without compromising on reliability.

Unlike many budget compressor brands that disappear after a few years, Airmaster has built a loyal following among hobbyists, small garages, joiners, painters, and light industrial users who want a dependable machine that won't break the bank. Machine Mart backs the range with in-store expertise, a nationwide network of service centres, and ready access to spare parts.

2. What to Look for in an Air Compressor

Before diving into specific models, it's worth understanding the key specifications you'll encounter when shopping for a compressor. These figures determine whether a machine will comfortably handle your intended tasks or leave you frustrated.

Air Flow (CFM)

CFM — cubic feet per minute — is arguably the most important spec. It tells you how much air a compressor can deliver continuously. Always check that your compressor's CFM rating exceeds the requirement of your most demanding tool. A typical nail gun needs around 2–3 CFM, a blow gun 3–5 CFM, and a spray gun 6–12 CFM or more depending on the cup size.

Tank Size (Litres)

The tank stores compressed air to handle peak demands and allow the motor to rest. A larger tank means longer working periods before the motor kicks in again — crucial for tasks like painting large surfaces. For intermittent jobs (nailing, inflating, cleaning), a smaller tank is perfectly adequate. For sustained spraying or running multiple tools, go bigger.

Maximum Pressure (Bar / PSI)

Most Airmaster models operate at a maximum of 8 bar (116 PSI), which comfortably covers all common trade and DIY applications. Check that your tools' minimum pressure requirements fall within the compressor's operating range — most pneumatic tools need 4–7 bar.

Drive Type: Direct Drive vs Belt Drive

Direct drive compressors — like the Airmaster Tiger range — connect the motor directly to the pump. They're compact, affordable and great for intermittent use. Belt drive compressors run slower, run cooler and last longer under sustained heavy use — the professional Airmaster 14-series models use this design. If you're using a compressor daily in a commercial environment, belt drive is worth the additional investment.

Power Supply

All Airmaster models in this guide run on standard 230V single-phase power, meaning they plug into a normal 13-amp domestic socket. This makes them genuinely portable and convenient — no need for a dedicated 3-phase industrial supply, even with the heavier belt-driven units.

3. The Airmaster Range at a Glance

Machine Mart's Airmaster lineup divides neatly into two distinct families. The Tiger series covers the DIY and semi-professional market with direct-drive, portable models in a range of tank sizes. The Professional Belt-Drive series — the 14-series models — targets tradespeople and light industrial users who need sustained, heavy-duty performance from a single-phase supply.

4. DIY & Semi-Pro: The Airmaster Tiger Range

The Tiger range is Airmaster's answer to the demands of home workshops, garages, small trade use and occasional professional applications. All Tiger models are direct drive, meaning they are compact and lightweight relative to their power output. They feature fully automatic stop/start controls, twin air outlets for multi-tool use, a safety pressure release valve, and a regulator with gauge as standard.

5. Professional & Industrial: Airmaster Belt-Driven Models

For tradespeople and workshop owners who need a compressor that can run hard, day after day, without overheating or excessive wear, Airmaster's belt-driven professional range is the answer. These machines use V-belt drive technology to run the pump at a lower RPM than direct-drive equivalents — generating less heat, less noise and significantly extending the lifespan of the pump. They're built for garages, bodyshops, joiners' shops and light industrial environments.

7. Which Airmaster Air Compressor Is Right for You?

Choosing the right Airmaster compressor comes down to three questions: how frequently will you use it, what tools will you be running, and does the machine need to be portable?

For occasional home use — inflating car and bike tyres, powering a nail gun for fencing, blowing out dust — the Tiger 7/260 or 8/260 are ideal. They're affordable, compact and perfectly adequate for light intermittent work. If you expect to do any spray painting, step up to the 8/260 which offers slightly higher output and the added benefit of a built-in intake filter.

If you're a keen DIYer who regularly takes on larger projects — spray painting a shed, running an impact wrench during car maintenance, stapling flooring — the Tiger 11/550 is the best value choice. The 50-litre tank makes a genuine difference to how long you can work before the motor cuts in, and 9.3 CFM handles most tasks without breaking sweat.

Tradespeople and serious workshop owners should look to the belt-driven range. If you move between sites, the 14/50P balances portability with professional output. If the compressor will live in one place, the 14/150 is our top overall recommendation — it represents the best combination of capacity, longevity and price in the entire Airmaster range. Only step up to the 14/200 if you're running a genuinely busy professional operation where two or more tools might be in use at the same time.

8. Tips Before You Buy

• Check your electrical supply. While all Airmaster models run from 230V 13A sockets, older circuits can deliver lower voltages. If your workshop supply is at the lower end, consider having it checked before buying one of the larger 3HP models.
• Think about placement. Belt-driven compressors are large and heavy. Measure your workshop space before purchasing and plan where the unit will sit. Allow clearance around the motor for air circulation.
• Drain the tank regularly. All piston compressors produce condensation in the receiver. Make it a habit to drain the tank after each use via the ball valve at the base — this prevents internal corrosion and extends the life of the machine significantly.
• Match the compressor to the tool, not to the task. Always check the CFM requirement of your most demanding air tool and ensure your compressor exceeds it — ideally with 20–30% headroom for comfort.
• Consider an air hose reel. If you're buying a larger workshop model, a wall-mounted hose reel makes an enormous practical difference to day-to-day usability and is available as an accessory from Machine Mart.

9. Our Overall Verdict

Airmaster air compressors represent some of the best value available in the UK market today. The range's longevity — sold continuously since 1989 — is a testament to consistent reliability, and Machine Mart's nationwide presence means you're never far from in-person support or spare parts.

The Tiger direct-drive range is exceptionally well-suited to DIYers, hobbyists and semi-professional users who need a capable, portable compressor without professional-level expenditure. The belt-driven professional models, meanwhile, are the choice of workshops and tradespeople across the UK — machines that will run for years with only basic maintenance.

Whatever your requirements, there is an Airmaster model that will meet them — and at a price that makes choosing this brand an easy decision.
