I've bought 3 of the Ridgid OF50150TS Tri-Stack 5 Gallon Air Compressor in the last two years. With 2 air outlets on the bottom tank and a separate air regulated outlet on the top tank this air compressor make our job easier as a framing contractor. The top outlet air pressure is turned down to 80 psi for our positive placement nail gun for installing nails into our structural hardware without denting the metal. The bottom tank air pressure is turned up to about 150 psi for our framing nail guns.
However, this Ridgid air compressor has broken down on us 3 times. The air compressor turns on, but wouldn't put out more than 30# of air pressure. We exchanged the first one that quit running correctly. A couple of weeks ago our third compressor quit running correctly. With two of these air compressors not working I went to the Ridgid website and contacted them on replacing parts in the air compressor. They didn't even respond. So I went to eReplacementParts.com and ordered 4 of the Outlet Reed Valves. Simple to install and now I have two of these Ridgid air compressors that work correctly.
Here's the Outlet Reed Value that broke.
