Can your compressor keep an air tool running?

Air tools have no electric motor of their own, so the compressor sets their limits. Each tool lists its air consumption in CFM at a working pressure, usually 90 PSI. Sustained users such as sanders and grinders need a compressor that can deliver that flow continuously, while impact wrenches and nailers work in bursts and are more forgiving. Check the inlet thread, commonly 1/4-inch NPT, and keep the hose bore at least as wide as the tool inlet. For square-drive tools, 3/8 inch suits lighter work and 1/2 inch suits larger fasteners.

Discs, cups, fittings and oil fit one system only

Many listings are consumables or parts rather than tools: sanding discs, spray gun cup lids, nozzles, grease fittings and hydraulic oil. These fit specific systems. A cup lid belongs to one gun family, a disc must match the sander's pad size and hole pattern, and hydraulic oil comes in viscosity grades such as ISO 68, which the equipment's manual names. Exhaust routing matters on sanders and grinders: an exhaust through the handle lets used air be piped away from the work. Tools listed for commercial use are built for long daily running.

Questions about Air Tools and Hydraulic Equipment

Why does my air tool lose power after a few seconds?
The compressor is probably not keeping up. When the tool uses more air than the compressor delivers, pressure falls once the tank empties. Check hose diameter and fittings for restriction as well, and compare the tool's consumption with the compressor's rating at the same pressure.
Do air tools need oil?
Most air motors need a few drops of air tool oil at the inlet each day, or an inline oiler, so check the manual. Use oil made for air tools rather than general-purpose oil. Tools marked oil-free skip this step.
What drive size does an air impact wrench need?
Match the drive to your sockets and the torque you need: 3/8 inch for small fasteners and tight spaces, 1/2 inch for lug nuts and general automotive work, and larger drives for heavy equipment. Use impact-rated sockets, not standard chrome ones.
