1. What is rotary air compressor?

Rotary Air Compressor is also called a Rotary Screw Air Compressor. As we mentioned before, there are two main types of air compressors: positive displacement type and dynamic type. The rotary screw air compressor belongs to the family of positive displacement air compressors.

working principle of rotary screw air compressor

The basic principle of this rotary air compressor is trapping air between two meshed rotors and reducing the volume of this trapped air as it moves down through the rotors. These two meshed rotors are the female and male rotors, which are driven either by the male rotor or by a timing gear. And the rotary air compressor is also called twin screw compressor.

2. What is a Single Phase Rotary Screw Air Compressor?

As a professional air screw compressor, the Single-Phase Rotary Screw Air Compressor is one of our star products.

Single Phase Rotary Screw Air Compressor

The “single-phase” comes in the terminology of electricity: in electricity, the word “phase” refers to the distribution of a load. The single-phase power is a two-wire alternating current (AC) power circuit: there’s one power wire (phase wire) and one neutral wire.

Single phase power supply

The single-phase power is also known as “residential voltage” for it’s widely used in residential homes.

For this reason, our Single-Phase Rotary Screw Compressor can be used in many applications, even in the residential application where the starting current of the residential power supply is relatively smaller.


3. What is the advantage of the rotary air pressor?

There are many advantages of the rotary screw air compressor, which mainly are the followings:

* Continuity of operation:

Unlike the piston compressor where there’s too much pulsation of surging of airflow, the rotary screw air compressor ensures a continuous sweeping motion.

Rotary air compressor vs Piston compressor

* Low noise:

Unlike the piston compressor where there’s a significant mechanical force to motivate the piston, the rotary air compressor works on a continuous and quieter sweeping motion. As a result, there’s less vibration and less noise from the rotary air compressor.

* Functions on extreme weather conditions:

This sweeping motion made by the two rotors makes the crucial components never wear out even in extreme weather conditions. So the air compressor works normally at high or low temperatures.

* Simpler maintenance:

The basic mechanism of the compressor is a rotary-type displacement made by two rotors, which is 70% fewer parts compared with other types of air compressors. Naturally, this simpler mechanism requires less maintenance work.

* Less heat-generating:

This rotary air compressor generates less heat during the air compression, which helps to reduce the water generated during the operation. And less water will get into the compressor or final application.

* Energy efficiency:

The biggest advantage of this air compressor is energy efficiency.

In particular, the single-phase screw compressor can be motivated by the electricity of a wide range of voltage. The single-phase screw air compressor even can work using a lower starting current of residential electricity. It costs only half that the compressor powered by industrial electricity does.
