Proto J150WA Air Impact Wrench 1/2 in Drive 200 Ft/lb

Product Description

The PROTO J150WA is a 1/2 inch drive inline air impact wrench designed for high-demand fastening and removal work in automotive, industrial, and mechanical service environments. It delivers 200 ft/lb of torque at 7,200 RPM with a rate of 1,600 blows per minute, making it well suited for lug nuts, heavy fasteners, and stubborn bolts. The tool operates at 90 psi and requires 5 CFM of air flow, connecting through a 1/4 inch NPT inlet. Exhaust exits from the bottom of the handle, directing air away from the work surface. At 4 pounds, it balances power and manageability for extended use.

The J150WA fits standard shop and field service setups where a reliable 1/2 inch drive impact wrench is needed. The inline handle style suits tight access applications and overhead work. It is appropriate for use by automotive technicians, mechanical contractors, and industrial maintenance crews. A minimum hose size of 3/8 inch is required to maintain adequate air delivery at the tool. This model ships individually and is well suited for single-technician toolkits or shop floor deployment.

Installation Notes

This tool is installed and operated by automotive technicians, industrial mechanics, and maintenance professionals working with compressed air systems. Before connecting to an air supply, confirm that the line pressure does not exceed the rated 90 psi operating pressure. Always use a minimum 3/8 inch air hose to avoid flow restriction that can reduce torque output. The 96 dB noise rating requires appropriate hearing protection in accordance with applicable workplace safety standards.
