Two massive quincy air compressor pumps for sale. Model qt150, capable of over 50cfm.
One pump has an issue with the head, check valves maybe?, but spins freely and sounds fine. Other is in good working order.
No longer have a use for these, would be great for a sandblasting compressor build, or upgrade your current compressor.
500 obo for both, these things are close to 9k new.
