Air Tool Kit: Will a Small Compressor Run It, and What's Missing?

You have a modest compressor and an air tool kit in mind. Before buying, you want to know which tools it will keep up with, whether spraying is realistic, and what else you need.

Short answer: compare each tool’s air use with the compressor’s free air delivery (FAD), and budget for hose, oil and fittings. PartsForMachines lists 52 Sealey, PCL, Draper, Sykes Pickavant and Tigren products in its air tool kits range.

I Have a Small Compressor: Which Tools in a Kit Will It Actually Run?

A small compressor copes best with tools used in short bursts, such as blow guns, nailers and air hammers. Compare each tool’s cfm at 90psi with the compressor’s FAD rather than its displacement: the 04397 24-litre compressor, for example, displaces 8cfm but delivers 5cfm FAD.

Between bursts, the tank has time to refill. Air motors in sanders and grinders draw air for as long as they spin, so a small compressor soon falls behind. The GSA12 medium-stroke air hammer kit, at 4cfm, is an easier match than a 7cfm die grinder such as the GSA67.

Will a Small Compressor Run a Spray Gun, or Should I Go Electric HVLP?

For a quick touch-up, yes; for a whole panel or a set of wheels, rarely without stopping. The gravity gun in the GCK01 compressor accessory kit uses 4.2 to 7.1cfm, and on long passes that can be more than a compressor delivering 2.4 to 5cfm FAD can replace, so the pressure sags.

Spray light coats and let the tank recover, or skip the compressor. The HVLP3000 electric HVLP spray kit is a 700W, 230V unit that makes its own air, with an 800ml pot and a 3m hose. It takes water- and oil-based paints, lacquers, preservatives and stains.

Starter Kit or Separate Tools: What Does an Air Tool Kit Actually Include?

Most kits fall into three types. Accessory kits cover the basics: the SA320K 19-piece blow gun kit has a palm blow gun, a 7m 6mm hose, couplings and adaptors, inflating needles, a tyre gauge and PTFE tape.

Single-tool kits pair one tool with its accessories in a case; the 83985 impact wrench kit adds eight sockets, an extension bar, a mini oiler and an oil pot. The 83431 68-piece multi-tool kit holds an impact wrench, ratchet, air chisel, die grinder and blow gun. A bundle is only good value if you will use most of it.

What Else Will I Need That the Kit Doesn’t Include?

Usually a suitable hose, the right plug for your coupling and some air tool oil. Many kit tools ask for a hose of at least 3/8in (10mm) bore, while the hoses in accessory kits such as the GCK01 and SA320K are 6mm.

Most kit tools have a 1/4in BSP inlet, so fit a plug that suits your compressor’s coupling. Keep the tools oiled: the SA2/TS impact wrench kit, for example, includes an in-line oiler and an oil pot. If you also paint, add a filter, because oil or water in the air can leave fisheyes and blisters in the finish.

What Should I Check Before I Buy?

• your compressor’s FAD (not its displacement) against each tool’s cfm at 90psi
• whether your jobs are short bursts or steady running (sanding, grinding, spraying)
• what is in the box: tool only, accessories, oiler, case or hose
• the inlet thread and your coupling type, so you buy the right plug once
• the hose bore the tools ask for (often 3/8in or 10mm), and clean, dry air if you will paint

Frequently Asked Questions

Which oil should I use in air tools?

Use an oil made for air tools, and check the tool’s manual before substituting anything else. SIP, for example, says its air tool oil helps stop scum building up and vanes scorching. Several kits, including the 83431 and 83985, come with an oil pot.

Can I spray paint through the hose I use for oiled tools?

Not if an in-line oiler has been feeding that line. Oil or water in the air reaching a spray gun can cause fisheyes or blisters in the paint, so keep the oiler out of the line that feeds your gun.

Do I need a filter at the gun end as well as at the compressor?

For painting, it helps. Water vapour condenses as compressed air cools, so moisture can form in the line after the compressor’s own filter. A filter close to the gun catches it; the 04397 compressor, for example, has its own filter regulator.

Will an extra air tank let my small compressor spray for longer?

A little longer, but it will not raise the delivery. A bigger tank stores air for short bursts above the compressor’s output; if the gun keeps drawing more than the FAD, the pressure still falls and you wait for it to recover.

Will a 6-litre compressor kit run a nail gun?

Yes, for trim nailing and stapling. The SAC0620AKIT compressor and nail/staple gun kit pairs a 6-litre, 2.42cfm FAD compressor with a gun for 10–50mm nails and 10–40mm staples, plus a 5m hose and a coupling kit.

Can I run an airbrush from a workshop compressor?

Yes, as long as you regulate the pressure down to the brush’s range. The 70831 airbrush kit works at 15–50psi and also includes an adaptor for compressed air canisters, handy for small jobs away from the compressor.

What pressure should I run a blow gun at?

Within the gun’s rating, and lower for cleaning. Kit blow guns such as the SA914 are rated to 110psi. Use a safety nozzle and never point it at anyone. Some countries set limits: US workplace rules require cleaning air below 30psi.

Is an adjustable blow gun better than an all-or-nothing one?

For delicate work, yes: a trigger that varies the flow lets you feather the air instead of blasting it. The blowgun in the GCK01 kit has trigger-adjustable flow of up to 270 L/min from a supply of up to 10 bar.

Do kit tools come with a plug for my compressor?

Some do. The 83738 air hammer kit and 83985 impact wrench kit each include an airline connector, but not every kit does. Most kit tools have a 1/4in BSP inlet, so fit a plug that matches your coupling’s profile.
