243 through 1,206 SCFM: Maxima Series is Mattei’s commitment to energy savings and environmental protection. This energy saver is ideal as a base load machine and unrivaled in combination when using an energy saving Optima VSD compressor as a trim machine. Together, they generate energy savings that are hard to beat.
Engineered like all Mattei’s to operate at standard motor speeds, Maxima’s massive airends turn at just 1,200 rpm versus our usual 1,800 rpm speeds. It is the incredible mechanical efficiency of Mattei airends that leverage this reduction in speed to deliver some of the lowest kW/100 CFM performance in the industry. In fact, the efficiency and output of single-stage Maxima rivals that of two-stage rotary screw type air compressors.
However, Maxima’s airend uses but two (2) Babbitt bushings versus the eight (8) roller bearings and (4) thrust bearings found in a two-stage screw, and about 1/3 of the oil. Maxima’s simplicity and durability will save you a fortune on energy, and simply deliver superior value and unrivaled durability over the life of the compressor, particularly when compared to rotary screw air compressors.
Benefit from sophisticated superior efficiency performance, quiet dependable operation and low maintenance costs. Featuring quiet (as low as 65 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 get superior performance and energy savings.
Save Energy, Save the Environment
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 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.
Available in 460v & 575v, 3Phase/60Hz.
CONDENSATE DRAIN AND SEPARATOR KIT
The kit includes a condensate separator and a timed electronic drain.
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%. (Model Maxima 55 and larger)
Leveraging the superior slow speed advantages engineered into all Mattei airends, Maxima boasts some to the lowest energy consumption per kW/100 CFM performance in the industry. Which rivals two-stage rotary screw air compressors with a fraction of the complexity and low cost of operation.
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.
Maxima Series compressors are cabinet enclosed machines that operate at a constant 1,200 rpm and deliver sound levels as low as 65 dB (A).
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. Single-stage screw type compressors use up to six (6) radial and thrust bearings engineered for only 50,000 hours (ASME B-10) of life.
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.
PREMIUM EFFICIENCY MOTOR
Premium efficiency totally enclosed fan cooled (TEFC) electric motors is standard on Maxima Series.
This is obtained with a flexible coupling between motor and compressor, without any need for belts. It is without roller bearings needing maintenance.
Energy saving wye delta motor starters is standard on Maxima Series.
Air cooled aftercooler with 18°F approach temperature. Moisture separator with automatic drain valve is optional on Maxima Series.
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.
Maxima Series is 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.
