Description

A Series Fixed Speed Screw Air Compressor

1.Twin-screw

Optimized design of airend allows enlarging capacity of compressor at same energy consumption, and it enables screw air compressor reduce your energy expense.

 

2.Computer control system

Display real time pressure and temperature and maintenance notice. Historical high temperature and high pressure is available to review.

 

3.Protection system

Motor overload protection, stop

High discharge temperature protection, stop

Over-pressure protection, stop

Phase fault protection, phase loss protection, stop

Lubrication display

Air oil separator block alarm

Oil filter block alarm

Air filter block alarm

Stop alarm

 

4.Display system

Discharge pressure

Oil pressure

Discharge temperature

Accumulated running time

Motor overload

Running condition

Stop

 

5.Air/oil separator

Oil flooded screw air compressor needs oil to absorb heat and noise, lubricate and seal air-end. It leads compressed air to be mixed with oil and needs air oil separator to reduce some oil. We use internal air oil separator, oil content less than 2 ppm which maximally reduce oil loss.

6.Cooler

Cooler is enlarged by 30% and prolong cleaning period.

 

7.Admission valve

Admission valve special design prevent reflowing. According to history air consumption, pressure signal is sent to control system and adjust air absorption by the way of controlling valve’s opening angle. It makes air delivery more efficient.

 

8.Minimum pressure valve

The non-metal double vertebral body structure design is sensitive and close quickly to avoid air back-flowing and pressure loss.

 

9.Motor

Use closed air cooled design, IP54, insulation grade F, service factor 1.15, SKF bearing
