Fixed Speed Screw Air Compressor

1 Two screw air compressor

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

a.Motor overload protection, stop

b.High discharge temperature protection, stop

c.Overpressure protection, stop

d.Phase fault protection, phase loss protection, stop

e.Lubrication display

f.Air oil separator block alarm

g.Oil filter block alarm

h.Air filter block alarm

i.Stop alarm

4 Display system

1.Discharge pressure

2.Oil pressure

3.Discharge temperature

4.Accumulated rum time

5.Motor overload

6.Running condition

7.Stop

5 Air oil separator

Oil flooded screw air compressor needs oil to absorb heat and noise, lubricate and seal airend. 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 2ppm which maximally reduce oil loss.

6 Cooler

Cooler is enlarged by 30% and prolong cleaning period.

7 Admission valve

Admission valve special design prevent backflow. 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 backflow and pressure loss.

9 Motor

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