- Soundproofed E version with dryer: Particularly suitable for applications where dry, moisture-free air is of crucial importance for production.
- Soundproofed S version on receiver: version mounted on 80- or 120-gallon horizontal ASME certified air receiver tanks.
- Soundproofed SE version with dryer on air receiver tank.
- Version with IE4 energy-efficiency motor.
Equipped with high efficiency IE3 electric motors. The low rotation speed of the air end and the 1:1 direct coupling between the electric motor and the compressor ensure energy savings of more than 15% compared to other rotary compressors.
When compressed air is required within 100% and 40% of flow rate values, the compressor rotation speed adjusts to maximum efficiency levels, with notably lower energy consumption in comparison with traditional inverter systems.
Optimized Cooling System
Oversized coolers are rated for 115°F ambient conditions. A permanent magnet motor driven variable speed electric fan regulates the cooling air flow depending on the machine oil temperature.
Simple, Economical Maintenance
Maintenance is limited to changing the oil at scheduled intervals, cleaning or changing the air filter and cleaning the radiator. The absence of roller bearings contributes significantly to reducing maintenance costs. These standard maintenance costs are, however, low due to the almost unlimited lifespan of the vanes, rotor and stator if proper maintenance is performed. Over 100,000 hours of operation are guaranteed without the need to replace the compression unit.
Compact Design and Silent Operation
The compact design and small footprint allow installation even in confined spaces. Large hinged doors and easily removable panels allow complete accessibility for all maintenance and service operations. The base is equipped with openings that permit easy lifting and handling.
Mattei air compressors are coated with epoxy powders, resistant to both corrosion and scratches. The interiors are also coated with abundant soundproofing material.
The 99% efficient filtration system ensures quality compressed air for every application, while the special multi-stage oil separation guarantees a residual oil content in the air of less than 3 ppm w/w.
RVD 7i-11i series compressors are equipped with a Maestro XB electronic controller, whose graphic display allows constant monitoring of oil temperature, line pressure, operation, and load hours.
