Why Choose Pneumatic Over Cordless?
Pneumatic impact wrenches deliver constant torque without battery fade. This 1,000 ft-lbs wrench weighs just 4.2 lbs — roughly half the weight of an equivalent cordless, reducing fatigue during extended use. No batteries to charge, no motors to overheat, and the twin hammer mechanism is built to last 10+ years with proper maintenance. Read our full pneumatic vs cordless comparison.
Air Supply Requirements
This impact wrench operates at 90 PSI and requires 5-7 CFM for average intermittent use. A 20-gallon compressor with 5+ CFM output handles most applications. For continuous heavy-duty use, a 30-gallon compressor with 7+ CFM is recommended. See our complete CFM & PSI requirements chart for compressor sizing details.
Recommended Accessories
For best performance and tool longevity, pair this impact wrench with an inline filter/regulator to deliver clean, properly pressured air. Add 2-3 drops of pneumatic tool oil before each use session. See our maintenance guide for the complete care routine.
Frequently Asked Questions
What size compressor do I need for a 1000 ft-lb impact wrench?
A 20-gallon compressor delivering at least 5 CFM at 90 PSI handles intermittent use. For sustained heavy-duty work, size up to a 30-gallon compressor with 7+ CFM output. Apply the 1.5x rule: your compressor should deliver 1.5 times the tool's CFM requirement.
How much does this impact wrench weigh?
This impact wrench weighs approximately 4.2 lbs — significantly lighter than comparable cordless models (6-8 lbs with battery). The lightweight aluminum housing reduces fatigue during extended professional use.
What applications is the 1000 ft-lb impact wrench best for?
This wrench excels at automotive work (lug nuts, suspension bolts, brake calipers), equipment assembly, structural bolting, and any application requiring high torque in a compact form factor. The twin hammer mechanism provides smooth, controlled torque delivery.
