Showing Questions of 1

My current compressor is a 5hp 21.5 cfm. Will this be enough power to handle this unit. Your spec says 7.5 max. If this one will not fit do you have one that compares to mine?

A: When using a true 5 hp motor, this compressor could be run at 800 rpm. At that rpm, it would provide 20.52 cfm open flow, and 16.01 cfm at 175 psi. If your compressor is not a true 5hp, there could be issues. Some manufacturers overstate the capabilities of their motors. A true 5hp motor will pull approximately 23-25 amps on 230vac power.
