Quincy QR-25 Overview

The QR-25 is pressure lubricated in all critical areas, runs at slower speeds and features durable cast iron construction for longer life and less downtime. Because the QR-25 operates at slower speeds, it’s capable of producing more CFM per horsepower. The QR-25 can also deliver up to 500 psig, making it suitable for the most challenging air compression tasks.

The Quincy QR-25 also features a revolutionary disc valve design that enables it to operate efficiently at lower temperatures. The intake loaders are designed to reduce horsepower during low-demand applications, which helps to extend valve life. Loadless starting reduces much of the strain on the motor, which also lowers energy consumption — and costs. The positive displacement rotary oil pump provides sufficient lubrication to all vital compressor components, which ensures smooth operation and further reduces oil temperature.

Maintenance of your QR-25 is a breeze, which contributes to the ease of operation and low cost of ownership. While most of the required maintenance involves the valve system, the valves are designed for easy accessibility – you won’t have to worry about dealing with cumbersome processes such as removing the cylinder head or unhooking the discharge line.

The Quincy QR-25 Delivers Excellent Long-Term Value for Your Money

The selection process for purchasing an air compressor should entail much more than looking at the purchase price: You should also consider how much it will cost to own and operate the compressor over time. Because the Quincy QR-25 produces more air per horsepower than other compressors on the market, you’ll notice a significant reduction in your energy costs which will save you a substantial amount of money. The QR-25’s built-in reliability also greatly reduces the possibility of compressor failure and costly downtime.

A Proud Legacy of Excellence

The modern-day Quincy QR-25 traces its roots to the 1930s when it was introduced as a member of what was simply known as “the Quincy Line.” A portable QR-25 version was introduced during the 1950s and was used to provide heated compressed air to keep lenses clear on military equipment. The first four-cylinder QR-25 was unveiled during the 1960s and the Coast Guard began using the QR-25 as part of its tug boat starting procedures in the 1970s.
