Mattei's ERC Series contains traditional open-frame air compressors designed for performance and value. Known for reliability, this series features sleek in-line construction, simple controls, quiet dependable operation and low maintenance.

ERC Series is friendly to your wallet and the environment as each holds very little lubricant (typically less than half that of a screw type 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, so it sees very little lubricant, provides up to 10,000 hours of service and low 1-3 ppm oil carryover.

STANDARD FEATURES:

STANDARD EFFICIENCY MOTOR
ERC models are equipped totally enclosed fan cooled (TEFC) drive motors through 30 HP as standard. 40 -60 HP models are equipped with open-drip proof (ODP) as standard and TEFC motors are available as an option.

MOTOR STARTER
Full voltage motor starter (to 30 HP), wye delta starter (40 HP – 60 HP).

AIR TREATMENT
Air cooled aftercooler with 18°F approach temperature, moisture separator with automatic drain valve.

MAINTENANCE
Maintenance operations only include changing the oil at predetermined intervals, replacing the air filter and cleaning the radiator. Benefit from oil separating filters that can reach 10,000 working hours, for significant savings over the life of the machine.

RELIABILITY
These compressors are designed for industrial use 24/7 at constant pressure. Mattei compressors are engineered to operate >100,000 hours.

INHERENTLY QUIET
ERC Series compressors are open-frame machines that operate at a constant 1,800 rpm and deliver sound levels as low as 64 dB (A) WITHOUT a sound enclosure – try that with a rotary screw compressor.

BEARINGLESS AIRENDS
Mattei Rotor Stator Units (RSU) consist of a single rotor supported by two (2) white metal bushes that routinely deliver >100,000 hours of life and never require and overhaul. Compare that to screw type compressors that use six-or-more radial and thrust bearings and typically provide a fraction of that time before overhaul.

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
On/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.
