Package Oil-Free BEBICON : Features

V-type (Variable Speed Control)

Energy-saving! 15% *1
Power-saving (Constant-pressure control with Inverter)
Constant-pressure control system can keep discharge pressure in the range of +/- 0.03MPa of setting pressure and can control motor rotating speed in proportional to air consumption.
This system allows lower pressure setting than conventional control system, such as pressure switch or unload valve control system, and saves electric cost. Pressure setting can be done with switches on the compressor panel at every 0.01MPa in the range of between 0.60 and 0.88 MPa of 5.5kW model and between 0.60 and 0.78 MPa of 7.5 & 15 kW models.

Condition : constant-pressure control comparison with conventional model at air volume ratio of 70%

Power-saving

VM Combi System

Ideal power saving with the V-type and M-type BEBICON combined operation

Environmentally-friendly with oil free structure

  • Oilfree air supply
  • No oil exchange program
  • Oilfree drain
  • No oil contamination

Digital indication

time counter

time counter

Easy-to-see time counter provided as standard

  • The compressor is provided with a time counter(standard feature)for digital display of not only air pressure but also operating time.
  • The digital display panel and the MAINTENANCE lamp positively indicate the time when to overhaul the compressor.

Simple operation by coordinated control of compressor and air dryer.(types with built-in air dryer)

Pre-operation of the air dryer or simultaneous operation of the air dryer and compressor can easily be selected by a single switch.

Simple operation by coordinated control of compressor and air dryer.(types with built-in air dryer)

Conventional Type

Conventional Type

  • Regardless of the mode of operation, the air dryer starts or stops automatically according to the amount of air used, ambient temperature, etc.
  • If any abnormal condition occurs with the air dryer in operation, the compressor and air dryer are automatically stopped and the MAINTENANCE lamp lights. *1
  • Use of a smaller-sized air tank made it possible to design a more compact compressor. *2

Note

*1
Even in this case, the compressor can be put into independent operation from the operation panel.
*2
The air tank need not be drained. However, when the compressor has not a built-in air dryer and neither an independent air dryer nor a vertical tank is installed. It is recommended that the air tank be provided with a drain or air filter.
