Porter Cable C5510 Compressor Cast Iron Cylinder Pump Oil Lubricated 20 Gallon Tank 150 PSI 10.1 CFM 1.9 HP 110/220V (currently set up as a 220 unit as it has been my shop compressor) but it can easily be switched to 110. Tank has been drained at the end of every day since new and never used outside. Very quiet for a compressor. New hose fittings installed a year ago. The horizontal style of Porter Cable is hard to find and is an excellent, well maintained unit so don't bother low balling me as I won't respond. The compressor is located in my shop down in Ladysmith so we'll need to arrange a time for my bud to meet you if you want a "test drive".
