Air Staple Guns

About Air Staple Guns

Air staple guns are pneumatic fastening tools that use compressed air to drive staples quickly and efficiently into wood, fabric, insulation, and various other materials. Powered by workshop air compressors rather than batteries or 240v mains electricity, these professional-grade tools deliver consistent driving force throughout extended working periods, making them ideal for high-volume applications in carpentry, upholstery, roofing, and construction. MyToolShed.co.uk stocks air staple guns from leading manufacturers including DeWalt, Makita, Bostitch, Rapid, and Sealey, with models accommodating staple lengths from 10mm to 38mm.

The pneumatic design eliminates battery weight, resulting in lighter, well-balanced tools that reduce operator fatigue during prolonged use. Most air staplers connect to standard compressors via quick-release fittings and operate efficiently at 4-8 bar pressure. Professional models feature adjustable depth settings, tool-free jam clearing mechanisms, ergonomic rubber grips, and safety triggers. Versatile 2-in-1 models like the DeWalt DPSB2IN1 can fire both staples and brad nails, offering excellent flexibility for varied fastening tasks.

Applications

Air staple guns are used across numerous trades and industries, including:

• Carpenters and Joiners – Securing trim, mouldings, drawer bottoms, and furniture assembly
• Upholsterers – Attaching fabric to frames, fitting webbing, and securing foam padding
• Roofers – Installing roofing felt, breathable membranes, and insulation materials
• Shopfitters – Fitting display panels, backboards, and decorative trim in retail environments
• Picture Framers – Assembling wooden frames with minimal surface marking
• Fencers and Landscapers – Attaching mesh, wire, and fabric to wooden posts
• Insulation Installers – Fixing vapour barriers and membrane materials to studwork
• Cabinet Makers – Assembling drawer boxes and fitting back panels

Choosing The Right Air Staple Guns

Staple Size Compatibility: Verify the staple length range matches your applications. Most models handle 10-38mm staples, with narrow crown widths (6-12mm) ideal for finish work and wider crowns providing greater holding power for structural tasks.

Air Compressor Requirements: Check your compressor delivers adequate CFM (typically 2-4 CFM) and pressure (4-8 bar). Ensure sustained operation won't deplete tank capacity during high-volume work.

Magazine Capacity: Professional models typically hold 80-120 staples. Larger capacities reduce reloading frequency on demanding jobs.

2-in-1 Versatility: Tools accepting both staples and brad nails eliminate the need for multiple fastening tools, offering excellent value for varied applications.

Ergonomics: Consider weight, grip comfort, and exhaust deflectors. Models from Makita and Bostitch available at MyToolShed.co.uk incorporate excellent ergonomic features for extended use.

Adjustment Features: Tool-free depth adjustment and quick-release jam clearing minimise downtime and allow rapid adaptation between materials.

Safety Information

Always wear safety glasses when operating air staple guns to protect against flying debris. Ensure hearing protection during extended use, as pneumatic tools generate significant noise levels. Verify operating pressure matches tool specifications before connection—excessive pressure can cause dangerous misfires. Never point the tool at yourself or others, and always disconnect the air supply before maintenance, clearing jams, or loading staples. Keep your free hand clear of the discharge area and maintain a firm grip throughout operation. Inspect air hoses regularly for damage and ensure all connections are secure. Comply with HSE guidelines for pneumatic tool operation and proper user training.

Frequently Asked Questions

What size air compressor do I need for an air staple gun?

Most air staple guns require a compressor delivering 2-4 CFM at 6 bar (90 PSI). A 24-litre or larger tank is recommended for sustained use, though professional tradespeople typically benefit from 50-litre or larger models that maintain consistent pressure during high-volume applications.

How often should I oil my pneumatic staple gun?

Add 3-5 drops of pneumatic tool oil into the air inlet before each day's use, or after every 2-3 hours of continuous operation. This essential lubrication maintains internal seals, prevents corrosion, and ensures smooth operation. Alternatively, install an inline oiler for automatic lubrication.

What's the difference between narrow crown and wide crown staplers?

Narrow crown staplers (6-12mm width) leave a smaller footprint, making them ideal for finish carpentry and trim work where appearance matters. Wide crown staplers (12mm and above) provide greater holding power for structural applications, insulation installation, and situations requiring maximum grip strength.
