Efficiencythat shows up on your bill
Soft start
With the drive, the starting current never exceeds the rated value, compared with 8 to 10 times for a direct or star-delta start.
Constant pressure
Smart PID regulation and dynamic control that prevent generating excess pressure in the network.
Air-oil separation
Two stages (centrifugal and a high-efficiency 8,000-hour separator) with less than 3 ppm of oil.
Up to 46 °C ambient
Oversized coolers that keep the unit running smoothly up to 46 °C (115 °F).
Internal designof the MNA series
The components that make the MNA an efficient, easy-to-maintain unit.
- New compressor unitImproved rotor profiles, developed in Japan and designed for many years of operation.
- IE4 permanent magnet motorIE4 standard efficiency, oil-cooled, with variable speed (VSD) and IP65 protection.
- Heavy-duty intake filterFilters 99.9 % of particles larger than 0.3 microns, with a differential gauge and a 2,000-hour service interval.
- VSD fanDrive-controlled, compact, low-noise, with high cooling capacity and low power consumption.
- Oil cooler and aftercoolerEasy access for maintenance and a surface with anti-corrosion paint.
- Flow Vector inverterWide-voltage design, integrated DC reactor and independent cooling air duct.
- PLC with IT 7000 touchscreenController designed for permanent magnet motors, with a rugged enclosure for trouble-free operation.
- Intake valveOptimizes air intake to the compressor unit; aluminum design and vacuum of up to 700 mmHg with low power consumption.
Everything in one placeintegrated dryer and tank
Integrated dryer
The all-in-one system includes a high-efficiency, reliable air dryer.
- Temperature differential of only 5 °C (41 °F) between inlet and outlet, with eco-friendly R134a refrigerant.
- Water-air separator with 99.9 % efficiency and automatic drain.
- Ultra-quiet refrigeration compressor and condenser with anti-corrosion nanocoating.
Large-capacity tank
A large-capacity tank reduces discharge flow pulsation and stabilizes system pressure.
- Fewer compressor cycles and less wear.
- Air reserve on hand.
- Masia synthetic lubricants rated up to 8,000 hours, made in the U.S.
