Quincy 230-33 Single Stage 2 Cylinder Air Compressor Pump

The Quincy 230-33 is a robust, single-stage, two-cylinder air compressor pump designed for industrial applications requiring reliable compressed air delivery. Manufactured by Quincy Compressor in Quincy, Illinois, USA, this model features a 3.5-inch bore and 3-inch stroke, making it suitable for light to medium-duty tasks such as powering pneumatic tools, spray painting, and general shop air supply. Its forced lubrication system ensures longevity and smooth operation under continuous use, with a belt-driven pulley for easy integration with electric motors or engines. Advantages include durable cast iron construction for vibration resistance and heat dissipation, outperforming lighter aluminum models in harsh environments. However, as an older design, it may require more maintenance than modern oil-free units and is noisier in operation. This used unit shows signs of wear including surface rust and paint chipping but appears mechanically intact with no visible major damage. Ideal for workshops, garages, or small manufacturing setups, it offers cost-effective performance compared to new equivalents, though buyers should verify compatibility with existing systems. Estimated market value reflects its refurbished potential and vintage appeal.
