More and more people choose or update a VSD (Variable speed drive) or VFD (Variable frequency drive) air compressor for their industry. What are the benefits of a VSD air compressor compared with a Fixed-speed air compressor? Is a VSD compressor the right choice for your facility? What is a Variable
What is the difference between an oil-free and oil-lubricated air compressor? The difference is the oil content in compressed air. For the Class 0 oil-free air compressor, we use water as the lubricating medium instead of oil(Water-injected oil-free single-screw air compressor) or use no lubricating medium(Dry oil-free double twin-screw air compressor), so there
In recent decades, there has been more and more research on the oil-free screw air compressor. According to the type of lubrication, the Screw type air compressor has two kinds: the water-lubricated single-screw type and the dry twin-screw type. For the Dry oil-free screw air compressor, most are twin-screw air compressors. Water-lubricated oil-free screw air
When it comes to the screw type air compressor, generally, there are two kinds, single-screw type and twin-screw(or double-screw) type. We will make a comparison between these two kinds of air compressors. Differences Single-screw air compressor Twin-screw air compressor Structure A screw rotor and two symmetrically starwheels. The screw
In recent years, screw air compressors have gradually replaced piston type air compressors. They become the mainstream in the air compressor market. The following mainly introduces the difference between screw type and piston type. Differences Screw air compressor Piston air compressor Scope of application The widest scope of application. The large scope
An appropriate selection is beneficial to both the end-user and the compressor equipment. A too-large selection is too wasteful. A too-small selection may lead to the compressor in a long-term loading state or insufficient airflow or pressure. The pressure and flow requirements for your facility are essential when choosing an air compressor.
For buying an air compressor, how to choose the right one for your industry? you should ask yourself these questions: What is the compressed air applied to? How much flow does my facility use? What is the pressure of my facility need? What is the compressed air quality you need? Do
With constant power, when the rotation speed changes, the flow and pressure also change. For example, a 22KW air compressor: when the pressure is determined to be 7 bar, the airflow is 3.7 m3 / min. when the pressure is determined to be 8 bar, the airflow is 3.4 m3
The VSD(Variable Speed Drive) air compressor uses the variable frequency inverter compared with the regular Fixed speed air compressor. The advantages as follows: Achieve constant pressure air, provide stable air source for users Stable start reduces the impact on the power grid, extends the service life of the
For most small models, it is better to use the air cooling type air compressor. There are four shortcomings of Water cooling type air compressors: It needs a water supply and discharge system, which requires a large investment The life of water-cooling coolers is short In the winter,
