Jargon Buster

CFM (Cubic Feet per Minute)

The volume of air that a compressor can deliver. This is the most critical specification when matching compressors to tools. Most air tools list their CFM requirements, and your compressor must meet or exceed this figure for proper operation.

PSI (Pounds per Square Inch)

The pressure at which air is delivered. Standard UK workshop tools typically operate at 90-100 PSI (approximately 6-7 bar). Higher PSI ratings provide more headroom and consistent performance across multiple tools.

Tank Capacity

Measured in litres in the UK, this indicates how much compressed air can be stored. Larger tanks mean longer run times between compressor cycles and more consistent pressure delivery for demanding applications.

Direct Drive vs Belt Drive

Direct drive compressors connect the motor directly to the pump (more compact, noisier), whilst belt-driven models use pulleys and belts (quieter operation, longer lifespan, easier maintenance).

Duty Cycle

The percentage of time a compressor can run within a given period. A 50% duty cycle means the unit needs equal rest and run time. Professional workshops require higher duty cycles for continuous operation.

SCFM (Standard Cubic Feet per Minute)

CFM measured under standardised conditions (specific temperature, pressure, and humidity). This provides a more accurate comparison between different compressor models than basic CFM ratings.

How to Choose the Right Air Tools & Compressors

Selecting appropriate air-powered equipment requires careful consideration of several key factors:

Assess Your Tool Requirements

Start by identifying which air tools you'll use most frequently. Each tool has specific CFM and PSI requirements – your compressor must meet the demands of your most air-hungry tool. For professional workshops running multiple tools simultaneously, add the CFM requirements together with a 30% safety margin. Common requirements include: impact wrenches (4-5 CFM), spray guns (8-12 CFM), and nail guns (2-3 CFM).

Compressor Size and Portability

Consider where you'll use the equipment. Site workers and mobile tradespeople benefit from compact, portable compressors with wheels and carry handles, typically ranging from 6-50 litres. Stationary workshop compressors (100-270 litres) provide sustained performance for demanding professional applications but require dedicated space and potentially three-phase electrical supply for larger models.

Power Supply Considerations

Most UK domestic settings provide single-phase 230V power through standard 13A sockets. Compressors drawing more than 13A require dedicated circuits or three-phase industrial power. Check your electrical capacity before purchasing larger workshop compressors, and consider consulting a qualified electrician for proper installation.

Noise Levels

Workshop and domestic users should consider noise output, measured in decibels (dB). Oil-lubricated, belt-driven compressors typically run quieter than oil-free direct-drive models. For noise-sensitive environments, look for models rated below 75dB. Remember that HSE regulations require hearing protection above 85dB in workplace settings.

Oil-Free vs Oil-Lubricated

Oil-free compressors require minimal maintenance and produce clean air suitable for spray painting and food-safe applications. Oil-lubricated models demand regular servicing but offer longer lifespans, quieter operation, and better performance for continuous professional use. Consider your maintenance capabilities and application requirements.

Quality and Budget

Entry-level compressors from manufacturers like Einhell suit occasional DIY use, whilst professional tradespeople should invest in established brands such as DeWalt, Makita, or Milwaukee. Professional-grade equipment offers superior build quality, longer warranties, readily available spare parts across the UK, and consistent performance under demanding conditions.

Popular Accessories

Maximise the versatility and performance of your pneumatic equipment with these essential accessories:

• Air Hoses – Available in various lengths and diameters (typically 6mm or 8mm in the UK). PU coil hoses provide flexibility and space-saving storage, whilst rubber hoses offer durability for workshop use
• Quick Couplers and Fittings – PCL-type couplings are the UK standard. Quality brass or steel fittings ensure secure connections and minimise air leaks
• Air Line Filters, Regulators, and Lubricators (FRL Units) – Remove moisture and contaminants, control pressure precisely, and lubricate air tools automatically for extended service life
• Tyre Inflators and Pressure Gauges – Essential accessories for automotive work and general maintenance, ensuring accurate tyre pressures
• Blow Guns and Cleaning Attachments – Versatile tools for cleaning workpieces, machinery, and workshop areas
• Compressor Oil – Regular oil changes are essential for lubricated compressors. Use manufacturer-specified grades for optimal performance
• Storage Reels and Holders – Keep hoses organised, prevent trip hazards, and extend hose lifespan
• Airline Manifolds – Allow multiple tools to connect to a single compressor outlet, ideal for busy workshops
• Condensate Drains – Remove moisture automatically from compressor tanks, preventing corrosion and ensuring dry air delivery

Safety Information

Working safely with compressed air equipment is essential for preventing injuries and maintaining a safe working environment:

Personal Protective Equipment

Always wear appropriate safety glasses or goggles when operating air tools, as compressed air can propel debris at dangerous velocities. Hearing protection is recommended for prolonged compressor use, particularly in enclosed workshops. The HSE requires hearing protection in workplaces where noise levels exceed 85dB. Dust masks or respirators should be worn when air tools generate airborne particles.

Pressure Safety

Never exceed the maximum rated pressure for your tools or hoses. Inspect hoses regularly for wear, cracks, or damage, and replace immediately if compromised. Always release pressure before disconnecting hoses or servicing equipment. Never direct compressed air at yourself or others – even low-pressure air can cause serious injury if it enters the bloodstream through cuts or body openings.

Compressor Operation

Ensure adequate ventilation around compressors, particularly for petrol-powered models used on construction sites. Electric compressors should be earthed properly and connected to appropriate electrical circuits. Drain compressor tanks regularly to prevent moisture build-up and potential corrosion. Always follow manufacturer guidelines for maintenance schedules, and never modify safety valves or pressure relief systems.

Workplace Considerations

In professional settings, ensure air tools and compressors comply with relevant UK safety standards and HSE guidelines. Provide adequate training for all operators, maintain equipment service records, and conduct regular safety inspections. Secure air hoses to prevent trip hazards, and clearly mark emergency shut-off locations in busy workshops.

Frequently Asked Questions

What size air compressor do I need for home use?

For typical DIY applications like inflating tyres, powering nail guns for decking or fencing, and occasional spray painting, a 24-50 litre compressor delivering 6-8 CFM at 90 PSI will suit most needs. This size offers good portability whilst providing sufficient capacity for common tasks. If you plan to use air-hungry tools like spray guns or impact wrenches regularly, consider a 50-100 litre model with higher CFM ratings.

Can I run multiple air tools simultaneously from one compressor?

Yes, but your compressor must deliver sufficient CFM to meet the combined requirements of all tools being used concurrently. Add up the CFM ratings of each tool you'll run simultaneously and add 30% as a safety margin. Professional workshops often require large stationary compressors (150+ litres) with high CFM outputs to support multiple operators. Most portable compressors suit single-tool operation or sequential use of multiple tools.

What's the difference between CFM and SCFM?

CFM (Cubic Feet per Minute) measures air volume output, but can vary based on ambient conditions. SCFM (Standard Cubic Feet per Minute) measures the same output under standardised conditions (typically 20°C, 36% humidity, at sea level), providing a more accurate comparison between compressor models. When matching compressors to tools, ensure you're comparing like-for-like specifications – SCFM provides the most reliable figure for making purchasing decisions.

How often should I service my air compressor?

Oil-lubricated compressors require oil changes every 50-100 hours of use (or annually for light-duty applications). Check oil levels before each use. Drain moisture from the tank daily or after each use to prevent corrosion. Replace air filters according to manufacturer recommendations, typically every 100-300 hours. Belt-driven models need belt tension checks every 50 hours. Professional workshops with continuous use should follow manufacturers' detailed service schedules and keep maintenance records for insurance and warranty purposes.

Are air tools more powerful than cordless electric equivalents?

Air tools typically deliver higher power-to-weight ratios than cordless alternatives, making them lighter and more manoeuvrable for extended use. They also maintain consistent power output regardless of duty cycle, whilst battery tools experience performance decline as batteries discharge. However, pneumatic tools require compressors and hoses, reducing portability. Professional mechanics and workshops favour air tools for sustained performance, whilst cordless tools excel for site work and locations without compressed air infrastructure. Consider your working environment and application when deciding between pneumatic and battery-powered equipment.
