Emglo Information

The big question is “who makes emglo air compressors?” Well, they were commonly referred to as DeWalt Emglo air compressors, let’s take a look at the DeWalt emglo compressor journey! In 1992, a man named Peter Leiss purchased the Jenny division of Homestead Industries and relocated the plant to Somerset, Pennsylvania across the way from his privately owned Tool & Die, Machining, Welding, Fabricating and ASME Code Air Compressor Tank Shop.

In 1998, Davey Compressor Company was purchased and joined the Jenny product offering. Davey Compressor, an off-shoot of the Davey Expert Tree Company, was a leading innovator in the air compressor field. The company designed and built the world’s first, portable, air-cooled air compressor in the late 1920s and has remained on the cutting edge of compressor technology.

On November 20, 2003, Jenny air compressors purchased the Emglo line of Industrial Stationary Air Compressors and the entire air compressor pump manufacturing facility from Black & Decker/DeWALT prior to the relocation of their plant to Renosa, Mexico. . Jenny and their affiliated companies had been supplying and manufacturing a large number of parts, components, and assemblies for Emglo for over 30 years.

Because Jenny is formerly known as Emglo air compressors, virtually all of the part numbers are interchangeable.

I have an Am-780 What part is this above the unloader tube ?


I have an emglo 4 gal 2 hp hand carry compressor. When the tanks are empty it starts and fills up, no problem. when i use a tool and the motor needs to restart and top off the tanks it just humms and struggles and eventually trips the breaker. I have replaced the pressure switch which includes an external unloader valve twice, no change., each time. I have replaced the AC cord ( it was frayed). not sure of the next step? please help, its too heavy to throw out the window….

If you run it up the first time, and then just leave it for a spell, does it hold the air pressure?
If not, try checking the check valve. It might just be gunked up and cleaning usually fixes them.

It holds the air, but will struggle to refill and almost always trips the breaker.

In that case, the unloader tube is probably clogged, or crimped shut. Unless it’s the much less likely cold start valve.

Use a bigger awg extension cord maybe 14 or 12ga. 12/3 extension cord. Does your compressor do this when plugged directly into plug socket?

What is the cylinder head bolt torque for Emglo am700-hc4v, there are two different size bolts.

I’ve been looking, but can’t find a spec anywhere. But you could try

I didn’t check if that number works.
If not, given the nature of the gasket, I’d just snug ’em down and then maybe a quarter turn more. Looks like the middle pair are smaller just because they fit there.

Good luck. And please let us know if you get an answer.
