Showing Questions of 6

can be driven by honda 2.2 hp petrol engine? many thanks

A: As long as it's driven at the correct direction and rpm, it should work from that.

what HP and speed motor is right for this?

A: The compressor is rated for up to 1 HP. The speed at the compressor is 1000 rpm max. It would be a simple matter of sizing the pulleys to get the correct final rpm as long as the flywheel diameter and motor rpm are known.

I just purchased an air compressor of your company. Item # 4-1904. I think I need to add oil to it. Can't see any in sight glass. What kind of oil should I use? Is there a manual I can download off internet?

A: Any non detergent petroleum based oil can be used. SAE 30 is a common weight to be used. No manuals are available.

Is this oil cooled? SC

A: This is air-over cooled, splash lubricated.

With a proper motor hook up to this could I use it to blow out my sprinkler system

A: It probably could, would not be real fast but should do the job.

Is this one CCW as looking at the pulley end ?? Thanks very much ..

A: Yes, CCW when looking at the pulley with the air pump behind it.
