Question

Is this compressor suitable for a staight line sander?

Would it work for intermittent use, or not at all? I have a project that would benefit from a line sander, but after it is done I likely won't be using the sander very often, so I can't see spending big bucks on a high capacity compressor.

This compressor is suitable to run any air tool that requires 5.5 or less CFM at 90 psi. The straight line sanders sold by Northern Tool does require a compressor that produces higher CFMs.

The pump has a capacity of 16.9 oz. You would use SAE 30 non-detergent pump oil prior to break in. After 50 hours of break in you may use synthetic type lubricants.

Question

Outlet size

I use a air gun that requires 3/8 fitting & line. Spec states 1/4 outlet. Is that just a matter of changing coupler to 3/8 or is there more to it.

You would just unscrew the 1/4" fitting and replace it with a 3/8" fitting.

It can be transported on its side prior to adding oil to the pump and installing vented oil cap. After the oil and vented cap are installed, it must be hauled vertically.

I transported mine from the store to my home on its side. They brought it out to my truck on a fork lift on its side. It is packed VERY well and it is dry, you must add your own oil.

This does not come with anything to set it up for 230 volt. The wiring and the plug would have to be purchased locally and wired by a qualified technician.
