SPEEDAIRE 3AAH8 Needle Scaler

The SPEEDAIRE 3AAH8 is a pistol-grip needle scaler built for general-duty surface preparation. It uses a 2 5/8 inch stroke and delivers 3,000 blows per minute to remove rust, scale and coatings. The tool operates at a required pressure of 90 psi with a 1/4 inch NPT air inlet.

Sustained air consumption

Average air consumption during a 15-second run is 2.8 CFM, while demand at full load rises to 11.0 CFM. The gap between the two figures shows that continuous heavy use requires a compressor and supply line capable of delivering the higher flow without pressure drop.

Supply hose and pressure limits

A minimum hose size of 3/8 inch is specified to feed the tool at 90 psi. Undersized hose or long runs will restrict flow and prevent the scaler from reaching its rated 10.0 CFM performance. The fixed collar housing lock and push-button throttle are the only controls provided.

Questions about this item

How much compressed air does the 3AAH8 needle scaler consume during continuous operation?

The tool averages 2.8 CFM at a 15-second run interval and draws 11.0 CFM at full load, both measured at 90 psi supply pressure.

What air-supply components are required before the scaler can run?

A compressor capable of 90 psi, a minimum 3/8 in hose, and a 1/4 in NPT fitting at the tool inlet are all required for operation.

Will the 1/4 in NPT inlet on this scaler connect to the fittings on my older air hoses?

Yes, the 1/4 in NPT air inlet is a standard thread size used on many legacy hoses and couplers, so existing lines can be attached directly.
