15 through 350 SCFM: AC Series sets a new standard in air compressors with sophisticated high-efficiency performance, quiet dependable operation and low maintenance. Featuring quiet {as low as 66 dB(A)} cabinet enclosures, electronic controllers, energy saving soft-start Wye-Delta motor starters, premium efficiency TEFC motors, air-cooled aftercoolers and optional integrated refrigerated air dryers, to deliver unbeatable performance and energy savings.

Featuring our most advanced airend designs, AC Series must be compared on an SCFM basis – not based on HP. Why? AC Series produces more SCFM per HP than typical rotary screw air compressors. So, to do a fair comparison you usually need to select the next smaller size. In fact, it is not uncommon to select a smaller HP AC Series model to meet your air demands. AC Series For example, say you need about 130 SCFM. MATTEI can offer you our traditional 30 HP ERC Series model (129 scfm) or, we can offer you our 25 HP AC Series rated at 130 SCFM. Each produces about the same volume of air, but that 5 HP difference saves you money the moment you turn it on, month-after-month, year-after-year.

Mattei is friendly to your wallet and the environment, too. Each unit holds very little lubricant (typically less than half that of a rotary screw air compressor) which saves you a small fortune on oil changes and disposal costs. The oil filter is cleanable – yes, cleanable. The highly efficient mechanical air/oil separation chamber delivers high quality air to the air/oil separator filter thus, it sees very little lubricant and provides up to 10,000 hours of service, and low 1-3 ppm oil carryover.

Standard Features

  • Condensate Drain and Separator Kit " The kit includes a condensate separator and a timed electronic drain.
  • Energy Consumption — Thanks to the thoroughness these compressors were designed with, the energy consumption per kW/100 CFM is among the lowest in the industry. The regulation system is continuous and automatic with off-load operation and allows a very economic adaptation to the installation demands.
  • Reliability — These compressors are designed for industrial use 24 hours a day and 12 months a year at constant pressure. Mattei compressors’ running often exceeds 100,000 working hours, as evidenced by our Revolutionary 10 Year Warranty.
  • Incredibly Quiet — AC Series compressors are cabinet enclosed machines that operate at a constant 1,800 rpm and deliver sound levels as low as 66 dB (A).
  • Bearingless Airends — Much like the connecting rods on your engines crankshaft, the heart of the Mattei rotor stator unit (RSU) is the rotor which is simply supported by two (2) white metal Babbitt bushings that routinely deliver >100,000 hours of life. Screw type compressors use up to six (6) radial and thrust bearings engineered for only 50,000 hours (ASME B-10) of life.
  • Air Quality — The exclusive three-stage oil separating system guarantees a maximum oil carry-over in the air lower than 3 ppm. Moreover, the air cooled aftercooler ensure approach temperatures of 18°F or less.
  • High Efficiency Motor — High efficiency totally enclosed fan cooled (TEFC) electric motors is standard on AC Series
  • Direct Coupling — This is obtained with a flexible coupling between motor and compressor, without any need for belts. It is without gears or roller bearings needing maintenance.
  • Motor Starter — Energy saving wye delta motor starters is standard on AC Series
  • Air Treatment — Air cooled aftercooler with 18°F approach temperature. Moisture separator with automatic drain valve is optional on AC Series.
  • Maintenance — Maintenance operations only include changing the oil at predetermined intervals, cleaning or replacing the air filter and cleaning the radiator. Benefit from half the oil volume of rotary screw types, and oil separating filters that can reach 10,000 working hours, for significant savings over the life of the machine.
  • Capacity Controls Adapt to Your Demands — The layout and design of every air system is different. Thus, Mattei provides a variety of control schemes as standard to better adapt to the demands and dynamics of your system, to save energy and prevent short-cycling and ambient oil misting problems created by inflexible control schemes and underutilized compressors.
  • Modulation Operating Mode at Constant Pressure — Thanks to a modulating proportional intake valve that supplies air at constant pressure, these compressors can even work without air receivers. This method automatically adapts to system demands and is ideal for applications with little storage or continuous high air demands.
  • Automatic On Load / Off Load — Load/Off Load maintains line pressure within a minimum/maximum pressure range, and the compressor may stop and restart according to air demand. Ideal for applications with adequate air storage tanks or large variations in air demand.
  • Combined On/Off Load and Modulation Regulation — This regulation allows Mattei compressors to modulate within a set pressure range (for example, ± 4-5 psi). Should the air demand decrease, the compressor will off-load and stop, with evident energy savings. Ideal for applications with little storage and large variations in demand.
  • Electronic Controllers — 5 HP and 7.5 HP models are equipped with the MicoC controller.
    Models 10 HP and larger are equipped with an exclusive state-of-the art computerized controller, Maestro XS.
    Maestro XS, automatically controls, monitors and programs the unit’s operation, and has an option to connect to a PC for a remote control. If connected to other compressed air packages equipped with Maestro XS, the unit can become master of a compressed air plant, thus saving on the installation of a superior controller. Maestro XS can be interfaced via web or cellular technology to provide remote service monitoring.

Optional Features

  • High Efficiency Air Intake Filter Kit — Heavy-duty high efficiency air intake filter is an option for dirty, dusty environments. Removes solid particles > 3µ with a filtering efficiency up to 99%
  • Tank Mounted Compressors — MATTEI® even delivers superior value for your money with AC Series compressor packages from 5 thru 15 HP mounted onto 90 gallon air receiver tanks. Our 90 gallon tanks give you more than 10% extra energy saving air storage than common 80 gallon tanks.
  • Integrated Refrigerated Dryer — Integrates a refrigerated dryer into cabinet. Reduces installation costs and space requirements. space requirement.
  • Oil-Water Separator Kit — Oil-water separator is fitted inside the cabinet, to ensure separation of oil from the condensate drain water. (Models AC 15 and larger)
  • Converting Serial Board — Allows communication with the protocol converter. One serial board is required for each compressor. (Models AC 15 and larger)
  • Integrated Heat Recovery Kit — Plate type oil/water heat exchanger, thermostatic valve and connecting pipes mounted inside cabinet. Ideal for hot liquid process applications. (40 HP and larger)
  • Soundproofing Intake Air Duct — Fitted externally to the intake end of the cabinet. Reduces the sound pressure level by about 3 dB(A). (Models through 30 HP)
  • Air Treatment Products — Mattei offers comprehensive air treatment accessories to complete your air system including: in-line coalescing filters, refrigerated air dryers, desiccant air dryers, sterile in-line filters, air receiver tanks, timer and demand style condensate drains, and oil/water condensate separators.
