Air Polishers

About Air Polishers

Air polishers are pneumatic tools that deliver professional-grade buffing, polishing and finishing results across automotive, metalworking and surface preparation applications. Powered by compressed air rather than electricity, these versatile tools offer consistent speed control, reduced heat generation and excellent manoeuvrability, making them essential equipment for automotive detailing, body shops and professional finishing work. MyToolShed.co.uk stocks both standard 180mm disc air polishers for larger surface areas and compact 75mm mini air polishers for detailed work in tight spaces.

Connecting directly to workshop air compressors via standard quick-release fittings, air polishers typically operate at 6-7 bar (90 PSI) and require 4-6 CFM for optimal performance. The lightweight pneumatic design eliminates motor overheating issues common with electric alternatives, allowing continuous operation during extended polishing sessions. Their construction also removes electrical hazards in damp environments, whilst variable speed control enables operators to match tool performance to specific materials, from aggressive cutting compounds to delicate finishing work on sensitive surfaces.

Applications

• Automotive Detailers – paint correction, swirl removal and achieving showroom finishes on vehicles
• Body Shop Technicians – preparing and finishing painted panels before final inspection
• Marine Engineers – polishing gel coat, metal fittings and maintaining watercraft appearance
• Metal Fabricators – achieving mirror finishes on stainless steel, aluminium and brass components
• Classic Car Restorers – detailed polishing work on vintage vehicles and chrome components
• Maintenance Engineers – refurbishing machinery guards, equipment housings and industrial metalwork
• Professional Valeters – maintaining vehicle fleets and commercial transport to professional standards
• Furniture Restorers – polishing lacquer finishes and preparing surfaces for refinishing

Choosing The Right Air Polishers

Disc Size: Standard 180mm air polishers suit larger panels and expansive surface areas, whilst compact 75mm mini polishers excel at intricate detail work, recessed areas and curved surfaces. Many professionals invest in both sizes for comprehensive polishing capabilities.

Air Compressor Compatibility: Check your compressor's CFM output and working pressure against the polisher's requirements. Most air polishers need 4-6 CFM at 90 PSI (6 bar). A minimum 50-litre receiver tank is recommended for continuous operation, as smaller compressors may struggle to maintain consistent pressure during extended use.

Speed Control: Variable speed models offer greater versatility, allowing RPM adjustment for different compounds and materials. Lower speeds suit delicate finishing work and heat-sensitive surfaces, whilst higher speeds provide aggressive cutting power for correction work.

Build Quality: Professional-grade air polishers available at MyToolShed.co.uk feature metal gear housings, sealed bearings and robust air motors that withstand daily workshop use, ensuring consistent performance and reduced maintenance requirements.

Safety Information

Always wear safety glasses to shield against polish spray and airborne particles. Dust masks or respirators are essential when polishing generates fine particulate matter. Never exceed the manufacturer's recommended operating pressure, and always disconnect the air supply before changing accessories or performing maintenance. Regularly lubricate air tools with pneumatic tool oil through the air inlet to prevent internal corrosion. Ensure adequate workplace ventilation when using solvent-based compounds, and follow COSHH regulations when handling chemical polishing products.

Frequently Asked Questions

What size air compressor do I need for an air polisher?

Most air polishers require a compressor capable of delivering 4-6 CFM at 90 PSI (6 bar). A 50-litre or larger tank is recommended for continuous operation, as smaller compressors may struggle to maintain consistent pressure during extended polishing sessions.

What's the difference between 75mm and 180mm air polishers?

The 180mm models suit larger flat surfaces like car bonnets, doors and panels, providing efficient coverage on expansive areas. Mini 75mm polishers excel at detailed work, tight spaces, curved surfaces and intricate areas where larger tools cannot reach effectively.

How often should I lubricate my air polisher?

Add 3-4 drops of pneumatic tool oil through the air inlet before each use, or at least daily during regular operation. This prevents internal corrosion, maintains seal integrity and ensures smooth performance throughout the tool's lifespan.
