1/2 in x 12 in Air Belt Sander

The Ingersoll-Rand G1A120RS812 is a straight-grip air-powered belt sander built for heavy-duty material removal. Its fixed arm and 0.4 hp motor deliver a constant belt speed of 700 SFPM on a 1/2 in by 12 in belt. The tool suits metal fabrication, weld blending and surface preparation where consistent linear sanding is required.

Fixed arm, 1/4 in NPT inlet, non-locking lever

The fixed arm keeps the belt path rigid for repeatable contact on flat or contoured workpieces. A 1/4 in NPT air inlet accepts standard shop couplers, while the 3/8 in minimum hose size and 19 cfm consumption at 90 psi demand a capable compressor supply. The non-locking lever throttle requires continuous hand pressure, and the tool weighs 1.2 lb at 10 3/4 in long.

Verify compressor flow, hose size and oil routine

Before ordering, confirm your compressor can sustain 19 cfm at 90 psi through a 3/8 in or larger hose to avoid pressure drop. The 1/4 in NPT inlet must match your quick-connect fittings or be adapted. Plan for regular pneumatic-tool oiling and note the 93 dBA sound level requires hearing protection.
