Knowing a good deal when I come across one, and wanting to increase the capacity of my air supply in my garages. I purchased a new model LS580V-601 TriMax compressor. The Trimax is a 5 HP three cylinder air compressor by Bendpak. The 80 gallon vertical A.S.M.E. tank is manufactured by Manchester. The motor is a massive Baldor 213T frame TEFC. Baldor is one of the top American brand motors. And being totally enclosed fanned cooled makes it more suited in adverse operating conditions. It came standard with a Siemen’s magnetic starter. And a Furnas pressure switch. The heart of the compressor is the three cylinder two stage Puma cast iron compressor that is made in Taiwan. The compressor’s 950 RPM is relatively low thusly makes for lower noise level and last longer. Having two first stage cylinders that feed into a third second stage cylinder. All mounted on a common cast iron crankcase. The big argument for three cylinders verses inline two, is that it has more even cooling.
Being a two stage, it has a working pressure as high as 175 PSI. with an impressive output of 20.2 CFM and 22.8 @ 90 PSI. .
I have the new TriMax compressor plumbed into my BelAir 55 CFM refrigerant air dryer. My DevAir compressor will be the primary air source. And is set to come on at 130 PSI and kick off at 150 PSI. While the TriMax compressor is set to come on at 125 PSI and shut off at 135 PSI. Consequently it will only run when the Devair cannot keep up with my air demand.
With the two compressor located next to each other. I thought it would be good to compare the to units. Though there not in the same class, DevAir is a 100% duty rated industrial compressor with cast iron cylinders, heads, connecting rods, forged crank shaft, and a pressurized lubrication system. And has a Seven year warrantee covering the compressor. More ever the Devair comes at a premium price compared top the TriMax. However the TriMax is a great value not only for commercial use; but for home use.
The first half of the following video sound clip below has the Devair running by itself. It has a *********** slower pitch rhythm sound. Due to its’ larger diameter pistons and stroke along with its’ Low 635 RPM. Midway through you’ll hear it unload and the TriMax will start,, no pause. But you’ll notice a higher pitch sound along with a higher rhythm. In my opinion the Devair produces about a third less sound.
I set the clock on the post to compare the time each compressor takes to hit 150 PSI. Unfortunately the video clip didn’t workout. But I can tell you the results. Both tanks were emptied. With all valves closed I simultaneously started both compressors. After the 7 minutes and 10 seconds the Devair shut off as it hit 150 PSI. The TriMax continued on for another minute and 10 seconds. For a total time of 8 minutes 20 seconds to reach 150 PSI. That’s about 15% longer run time to reach 150 PSI.
