The Best Solution for Savings 68 through 1,254 SCFM:

Optima Series leverages the superior mechanical efficiencies engineered into Mattei’s rotary vane technology to lower your operating costs, particularly when compared to typical rotary screw air compressors. Benefit from sophisticated high-efficiency performance, quiet dependable operation and low maintenance. Featuring quiet (as low as 65 dB(A)) cabinet enclosures, electronic controllers, energy saving soft-starting AC inverter drives, premium efficiency TEFC motors, air-cooled aftercoolers and optional integrated refrigerated air dryers, to deliver unbeatable performance and energy savings across the entire range of variable air demands.

Turn Up the Savings
Don’t get caught up in the hype the rotary screw air compressor folks refer to in who’s got the better “turn down” ratios for VSD type air compressors. Every airend technology has an ideal speed range for best efficiency and performance. Rotary screw airends are very sensitive to variations in speed. Turn them too fast or too slow and the efficiency drops off significantly. Whereas, Mattei’s rotary vane airends never run too fast and deliver better energy efficiencies as they slow down, which lets you turn up your savings through lower operating costs at comparable flow rates.

How Can This Be?
Simple. Mattei’s rotary vane airend technology uses very little lubricant in the compression process to deliver ~90% mechanical efficiency air production, whose efficiency does not deteriorate as it slows down in speed. Conversely, rotary screw airend technology uses a lot of fluid to compress the air and delivers much lower mechanical efficiencies. Much like blowing through a straw into a glass, the air bubbles up through the oil and flows along the “blow hole” recirculating back to the suction side due to the high differential pressures along the length of the screws. Thus, rotary screw inefficiencies become more evident as speed increases, but more so as it slows down.

For example, say you need about 30 HP worth of air for a period of time and you have a 100 HP VSD type rotary screw air compressor. The performance curve shows higher kW/100 cfm requirements as the machine slows down in essence costing you 40 HP worth of energy to gain 30 HP worth of air. On the other hand, our Optima will reach minimum speed and begin to operate load/off load saving you significant power. That’s why we say, “Don’t let the rotary screw boys throw you a curve in saving energy.”

Save Energy, Save the Environment
Mattei compressors are not only friendly to your wallet, but the environment as well. 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 through most models; 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.
