Solid, Simple, Smart

The Mark MSU 3-10 is the ultimate workshop compressor: powerful, easy to use and always reliable. Thanks to its rotary screw technology, you get more air while enjoying lower energy costs. Better yet, you can use it all day long without cool-down periods. Of course you can tailor the MSM to your specifications and preferences. We have a 3-10 HP power range, and both floor- and tank-mounted models.

Cost-Effective to Buy and Own

The MSU doesn’t require a separate compressor room. That reduces logistical hassles such as piping, but also lowers your operational and your investment costs. How? The MSU 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 MSU, and thus to lower your investment cost significantly.

Cleaner Air

With an oil carry-over of less than 3 ppm, the MSU generates much cleaner air than a typical piston compressor (more than 30 ppm) to protect your pneumatic tools

Advanced Screw Air End

The MSU 3-10 comes with a new high-efficiency air end that delivers 15% more air and is 12% more efficient than its predecessor.

IE3 Efficiency Motor

Allows for continuous operation while reducing energy costs.

Refrigerant Dryer

If your application requires little to no moisture in the compressed air, a refrigerant dryer can be added to your MSU for dry, quality air.

Built to Last

Its automated screw air end manufacturing line prevents human error and ensures the MSU is as powerful and reliable in real life as it was designed.

Comfortably Quiet

The MSU 3-10 was built to be installed and used right where you need it: on your shop floor. That is why we made the unit extra quiet. With a sound level as low as 61 dB(A), the MSU is comparable to a household appliance.

More Air, Lower Energy Costs

The MSU series gets 15% more air using 12% less energy compared to its predecessor. Enjoy continuous use without cool-down periods.
