Variable Speed Air Compressor

Minnuo develops and produces variable speed air compressors (VSD compressors) that dramatically improve the efficiency of air compression,saving over 30% efficiency and reducing energy consumption by 26%.

What is VSD Air Compresor?

The so-called variable frequency is to change the power supply frequency of the motor, which is abbreviated as VSD (abbreviation of Variable Speed Drive), that is, the meaning of variable speed drive. Variable Speed Air Compressor can bring many benefits, it can reduce the starting current of the motor, reduce the impact on the user’s power grid, automatically adjust the load to reduce power consumption, reduce losses and extend the service life of the equipment.

Advantages of permanent magnet VSD Compressor

  1. Energy saving:
    The most significant advantage is energy saving, generally can save 10%~35% energy.
  2. Operating cost reduction
    After the frequency conversion starts, the impact on the equipment is reduced, and the amount of maintenance and repair is also reduced, so the operating cost will be greatly reduced.
  3. Reduce production losses.
    Energy-saving controllers are used to monitoring more than 20 parameters simultaneously, making the air system more stable and reliable, reducing downtime, and reducing production losses.
  4. Reduce the noise of the air compressor.
    After the frequency conversion speed regulation, the motor running speed is slowed down, and the noise is reduced.
  5. the pressure stability
    The frequency converter has step-less speed regulation, and it can start smoothly through the controller. For occasions where the gas consumption fluctuates greatly, it can quickly adjust the response.

  • The extra investment cost of inverter air compressor can be recovered in 1 to 2 years compared with fixed speed air compressor.

We focus on saving energy - VSD

The most important feature of VSD air compressor is that the motor speed is changed according to the air consumption to ensure the precise matching of air volume and demand, thus achieving energy saving and constant pressure.

vsd air compressor annual electricity use

For example 37kw screw compressor, the average annual operation is 8,000h, and the cost of electricity is $0.1. We save electricity than ordinary screw compressor per year.

218500-165620=52880KW

52880✖0.1=$5288

each year save $5288

Frequent Asked Question

By adjusting the power supply frequency to regulate the compressor motor’s speed and the central compressor’s speed, the compressor’s air output and the customer’s air consumption can be consistent. This flow regulation method can avoid a large amount of energy wasted in the imported flow regulation method and is the market’s most efficient air compressor flow regulation method.

In recent years, variable speed air compressors have become popular in the market because of their unique energy-saving effect. greatly improve the efficiency of the process (variable speed does not depend on the mechanical part) and can be more energy efficient than the original fixed speed operation of the motor. Here are ten examples of reasons to use variable speed to illustrate the basic understanding of the increasing popularity of inverter applications:
(1) Control the starting current of the motor

(2)reduce the power line voltage fluctuations

(3) the power required for starting is lower

(4) Controlled acceleration function

(5) Adjustable operating speed

(6) adjustable torque limit

(7) Controlled stopping method

(8) energy saving

(9) reduce mechanical transmission parts

Yes.Air compressors create compressed air, which is then stored in tanks. There are 3 general uses.

The first is the air for pneumatic doors, the speed and reliability of pneumatic doors are generally better than electric doors.

The second is a lot of valves, check valves, instrument lights are pneumatic valves, need to use compressed air to control the valve switch and instrument indication, etc..

The third is the air for blowing, generally used to blow the pipeline.

rpm refers to the speed of the air compressor spindle per minute.

VSD air compressor is 30%~50% energy saving than ordinary air compressor, the specific amount of energy saving depends on the working condition of the air compressor and the parameter setting of the inverter. The biggest influence factor is the working condition of the air compressor, under normal circumstances, the greater the fluctuation of gas consumption, the better the energy saving effect, and the most direct data is the proportion of no-load time to the total working time. Specifically, we can measure the daily, weekly and annual working hours of the air compressor with an electric meter, so that we can count how much money is saved.
