The Convincing Benefits of Screw Technology

Are you considering a piston compressor? The rotary screw technology of the QRS 3-20M offers much stronger benefits. A quick comparison of performance, noise, and air quality shows the QRS to be the better workshop solution.

Stronger performance

The QRS generates more air
and does so more efficiently
thanks to its superior
compression technology.

Longer working hours

While pistons need
cool-down periods, the QRS
can be used all day long.

Lower sound levels

The QRS 3-20M emits just
61 to 71 dB(A). Pistons are
typically 20 dB(A) louder.

Cleaner air

With an oil carry-over of
less than 5 ppm, the QRS
generates much cleaner
air than a typical piston
compressor (more than
30 ppm) to protect
your pneumatic tools.

Small footprint
Our QRS rotary screw compressors can be base or receiver mounted, with or without dryer to have a compact and all-in one system.

Fast & cost effective maintenance
No wearing parts: increases reliability and reduces maintenance costs.

Cost-effective to buy and own
The QRS doesn’t require a separate compressor room. That reduces logistical hassles such as piping and lowers your operational and investment costs. How? The QRS does not have to push its air through an elaborate network of pipes. This means less pressure drops and a higher Free Air Delivery, which generates significant energy savings. But it often also frees up the possibility of choosing a lower pressure and power variant of the QRS, and thus to lower your investment cost significantly.

Low noise
Quiet by design, the QRS can be installed almost anywhere, without disturbing your working environment. That is why we made the unit extra quiet. With a sound level as low as 61 dB(A), the QRS is comparable to a household appliance.

Built to last
Designed for continuous duty and very hard working conditions.

IE3 efficiency motor allows for continuous operation while reducing energy costs.

Refrigerant dryer can be added to your QRS for dry, quality air.

Super-silent canopy reduces sound emissions to a comfortable 61-68 dB(A).

Unique Condensate Prevention

If you don’t use your compressor continuously, investing in condensate prevention is a smart choice. The QRS eliminates the risk of condensation with a host of features, including an oil heater, a tropical thermostat, and a 60-gallon tank.

Equipped with the latest generation of screw element for improved free air delivery and efficiency

Easy to use, efficient, and reliable, the QRS range meets the compressed air demands of tire shops, paint shops, car dealers, maintenance shops and more. The range is quiet by design, allowing it to be installed almost anywhere in the workshop, without disturbing your working environment. Base mounted or tank mounted, with or without dryer, and with 100-175 psig pressure variants available, the QRS is a complete solution for your business.
