And in the world of amateurs
...
After trying several things, I screwed a 6 ft hose into the regulator then use a separate hose from there to the tool. its easier to wrap the short hose around the compressor for storage. Then coil the long hose separately. The Earthquake Version1 impact wrench is the most air-hungry tool I use. It had been starving for air. Now using these larger couplers it works great.
I am curious,,, what is wrapped for storage, it is not left connected? Seems like you might be a candidate for a reel?
Hobby farmer here. Retired. The orchard is contracted to a local guy to till and harvest. So my shop is what you would expect for a DIY'er with lots of hobbies. Not agribusiness, or welding for others. I maintain the road, dig out stumps etc with two elderly tractors and various stuff bought used. Nothing is urgent like it would be in a commercial operation.
My compressor is HF's 20 years ago, $99, 10 gallon unit. HF claimed 5 CFM. Same as their present 4 SCFM model.
When I bought the Earthquake impact wrench I tried everything to get maximum air from this cheap compressor. The high-flow fittings in my photo above were the improvement I needed for the impact wrench to get its rated torque. Everything works well now.
A hose reel would be handy but that would mean more couplers. Taking down an air hose from its garden-hose rack when I need it, is simple and sufficient. The short 6 ft hose is screwed into the compressor's regulator for fewer fittings and to put the first coupler out where its convenient.
I bought first class tools when I used them to earn a living. (And still have them). This HF air stuff, and welders bought used etc, are good enough for the projects I do now.
And a question: the compressor's switch is set to cut out at 125 psi. Is the 90 psi regulator beyond that switch, really needed? Seems to me its just another obstacle to air volume. Why not remove it when the main use of air is for air tools? For painting, I have a separate regulator/water trap out where I paint. Advice?
