Frequently Asked Questions
What air compressor do I need for the LE-R2550B 1/2" Air Ratchet?
This tool requires approximately 4-6 CFM at 90 PSI. A compressor with at least a 20-gallon tank provides sufficient air volume for intermittent use. For continuous operation, a 30+ gallon tank is recommended.
Is the LE-R2550B 1/2" Air Ratchet compatible with my existing air setup?
Yes. Like all Le Lematec tools, it uses a standard 1/4" NPT air inlet fitting that's compatible with most compressors, hoses, and quick-connect couplers from any manufacturer.
Why does this ratchet have a safety throttle lock?
The thumb-operated throttle lock prevents the tool from activating when accidentally bumped or dropped. This is a critical safety feature in crowded shop environments and is required by many industrial and manufacturing facilities. It also prevents unintended fastener loosening during transport or storage.
Is 70 ft-lb enough to replace an impact wrench?
No — air ratchets and impact wrenches serve different purposes. The LE-R2550B is designed for controlled fastener tightening and removal in accessible areas. Impact wrenches (like the Le Lematec 1,000 ft-lb model) use concussive blows for frozen, rusted, or very high-torque fasteners. Use the ratchet for speed and access; use the impact wrench for raw power.
How It Compares
The LE-R2550B prioritizes safety with its one-hand forward/reverse switch design, compared to the LE-R2150B which emphasizes raw torque output. Both are 1/2" drive, but the R2550B's ergonomic controls make it better suited for overhead work and confined positions where accidentally engaging reverse could cause injury. Compared to the LE-RW57, the R2550B offers smoother operation while the RW57 delivers higher maximum torque.
