Compressor Works Great

The Quincy compressor runs our whole shop with ease. Our router, plasma cutter, and tools. Very quiet which is a big change from our old piston unit. The Compressor World website was great to work with. Easily found the compressor, customized to our voltage, and placed the order. It was here in a week and installed in a day. Great overall experience and will definitely look to Compressor World for all of our maintenance needs.

System Works Great

We needed to build a portable air purifier skid to handle transformer work on the oil derrick tanks that we monitor and test. An air purifier combined with this Quincy compressor and additional filtration makes for a great system meeting all OSHA requirements. Compressor World was great in helping us meet the specifications that were required and providing all the equipment information that we needed and terms of delivery and installation. Pricing was budget friendly and dealing with Compressor World was great. Will look to use Compressor World again when we build out our next skid. Thanks for the follow up.

All good with the compressor. It is very quiet and reliable. Easy start up and runs through our 2 shifts with no problems. Impressed with the selection on the Compressor World website but we had a Quincy piston unit before and we are very happy with the Quincy brand. All questions that we had were quickly answered and we felt real comfortable with the purchase. We will look to Compressor World again.

An Excellent Compressor

The Quincy compressor works very well in our new location. Space was a concern so having an all in one unit with dryer and tank is a space saver while supplying the necessary air that we need. Matt at Compressor World was great in helping us with the best option and it was delivered in no time. Very happy with both the compressor and the experience with Compressor World and really appreciate the follow up to see how things are going. Very professional.
