Small-Sized Type / EFBS Series

Redesigned Oilfree Booster Compressor!

Top-runner standards are applied to motor of ESBS15-10.
More efficient energy savings!

Lowering pressure for energy saving

Why not lower the supply pressure of the compressor?

While 60 to 70% of the equipment used in a manufacturing plant is designed to operate on low pressures, pressures as high as 0.7 MPa are typically supplied.

Lowering the supply pressure of the compressor can bring these energy-saving effects:

●Energy-saving effect ①
The power consumption of the compressor decreases.
●Energy-saving effect ②
The air consumption (including air leaks) decreases.
●Energy-saving effect ③
The load of the compressor decreases.

Lowering the supply pressure by 0.3 MPa leads to an energy saving of about 20%!

CO2 emissions are cut by about 50 tons annually!

　　Three 37-kW compressors are used.

　　Operation time: 4,000 hours/year

　　Emission factor: 0.000555t-CO2/kWh

Calculated using the above conditions.

Motor output≒2.6 kW(100L/min→0.75 kW)

Power consumption kWh≒3.3 kWh(2.6 kW÷0.8)

CO2 emissions ≒7.3 t/year

(Operation time 4,000 h/year)

CO2 emissions ≒ 2.2 t/year

(Operation time 4,000 h/year)

Power consumption can be reduced by 70 %, and air consumption can be halved.

More than half of the energy is wasted during boosting.

Compared to the air-driven type, power consumption is reduced to 1/3!

Furthermore, the booster compressor ESTIBO reduces CO2 emissions by5.1 tons annually compared to the air-driven type!

●Features

The world's first oil-free type

The world's first oil-free compact booster compressor
The compressor can be installed easily even in narrow spaces where it was formerly difficult to install.

Low noise and low vibration

The closed-type compressor generates no valve noise. It is very quiet.

Long life

The compressor main unit requires intermediate maintenance at intervals of 10,000 hours.

A microcomputer board is included (EFBS15).

Pressure can be set arbitrarily.

Compact structure with an internal pressurizing mechanism (*) (EFBS04/07)

Compression loss is reduced to ease the motor load. No leak occurs during boosting.
Since the compressor can maintain gas purity, it is recommended for nitrogen gas boosting as well.
