Industrial Air Disc Sander 0.4 hp

The Ingersoll/Rand G1A200RS4 is a new pneumatic disc sander rated at 0.4 hp for industrial surface preparation. It runs at a free speed of 20000 RPM with a 1/4 in.-20 spindle and requires 90 psi supply pressure. Composite housing and handle materials reduce weight while a rear exhaust directs airflow away from the work surface.

Suited for continuous finishing tasks

Operators who need a lightweight right-angle sander for blending, deburring or rust removal on metal and composite panels will benefit from the 6.0 average CFM draw and lever throttle control. Buyers who need variable speed control or a larger pad diameter for heavy stock removal should look at alternative tool configurations.

Lever throttle and rear exhaust included

The lever throttle provides immediate on-off control without a separate speed regulator, simplifying operation during repetitive passes. Rear exhaust routing keeps the work area cleaner by directing spent air away from the disc, while the composite grip insulates the hand from vibration and cold air discharge.

Questions about this item

What compressor output do I need to run the 0.4 hp sander at 90 psi?

The tool requires 6.0 CFM average and 25.0 CFM at full load at 90 psi.

Will the 1/4 in. NPT air inlet connect to my existing 3/8 in. hose without an adapter?

The inlet is 1/4 in. NPT; the minimum hose size is 3/8 in., so a fitting or coupler is needed between them.

How can I confirm the sander is reaching its rated free speed after installation?

Under no load at 90 psi the spindle should turn at 20,000 RPM; use a contact tachometer to verify.
