Frequently Asked Questions
What air compressor do I need for the GP-250?
The GP-250 requires approximately 4 CFM at 90 PSI. For continuous use in a workshop, we recommend a 2HP or 3HP compressor with at least a 50L tank.
What is the difference between the GP-250 and GP-150?
The GP-250 is a long-stroke hammer (89mm) that hits harder but slower. The GP-150 is a short-stroke hammer (41mm) that hits faster but with less individual impact force. The GP-250 is better for heavy-duty demolition.
