Not long ago, Quincy pioneered the modular approach to rotary screw compressors with its QMA line. Now, they've taken that approach to the next logical step.

With the QMB And the QMT, Quincy has built the modular advantage into two new attractive, compact, and efficient rotary screw air compressors. Smaller than the QMA, the 10-30 horsepower QMB and QMT are both manufactured at Quincy's facility in Bay Minette, Alabama, one of the most technologically advanced compressor plants in the world.

Since the QMB and QMT airends are contained within their fluid reservoirs, they require fewer external piping connections and, therefore, less maintenance. Easy serviceability is assured with a quick-change separator, quick-release cabinet latches, a spin-on fluid filter, and convenient access to routine maintenance areas.

The QMB and QMT also feature full cabinets for quieter operation, and an instrument panel with large, 2-1/2" dampened movement gauges, for quick reading of critical operating data. In addition to these standard features, the QMB and QMT can be tailored to your individual requirements with such options as WYE-DELTA reduced voltage starting, a super-low sound attenuation cabinet, modulation with auto-dual control, and a host of other features. Add to all this their highly sophisticated, computer-aided design, and you'll see why the QMB and QMT are two more examples of why Quincy compressors are undeniably the world's finest.

Are You comparing apples to oranges when it comes to separation systems?

Fluid carryover can be measured in two ways. The first method measures the fluid carryover downstream from the aftercooler, moisture separator and trap. The amount of carryover is normally stated in ppm(parts per million) and is typically in the 3-5 ppm range. Most compressor manufacturers publish carryover rates based on this information, and while it is a relatively accurate measure of downstream fluid carryover(relative because the effectiveness of the moisture separator and trap at fluid removal will vary with the ambient air conditions) - it measures only 1/3 to 1/4 of the actual fluid passed by the separation system.

The second method, fluid make-up, is the method Quincy has traditionally used and measures the total amount of fluid lost in both the downstream air system and through the moisture separator and trap. This method provides the most accurate measure of fluid loss.

Don't be misled. Quincy's QMB and QMT products use a unique, highly efficient separation system and separator element that keeps fluid make-up under 3 ppm and, remarkably, fluid carryover under 1 ppm.

So be sure you're comparing apples to apples. When we say excellent fluid carryover, that's exactly what we mean-by-anyone's definition.
