 Brand Name



The air compressor is a specific type of gas compressor. Its main components are dust screen, oil filter, oil separator, lubricating oil, suction pressure regulating valve, compressor body, motor, oil cooler, post-refrigerator, belts, automatic temperature adjuster, unidirectional valve , and electromagnetic valve. Our company uses air compressors from Yaoquan Electrical Equipment Co., LTD as part of the auxiliary equipment to manufacture footwear. It can work with a single power supply and condensed air. This gas compressor has a cooling system inside which makes installation easier.


An air compressor is widely used in manufactures, including the production of footwear, trademarks, stickers, umbrellas, raincoats, portfolios, reticles, school supplies, inflatable toys, waterbeds, blinds and vacuum packages. In addition, hard / soft leather and PVC clothing (20% -100%) can be processed by this air compressor.


The gas compressor has a large volume compression set and the rotor rotation speed is low enough to perform optimum oil injection, which provides great efficiency and reliability. The last improvement ensures a low temperature of the compressed air, so all parts of the compressor can work better within a long hour of work.

(1) It has the properties of high stability, efficiency in addition to low vibration and low noise.

(2) Double screw rotors are coordinated, through control, with the machine housing, which reduces the return flow of the air and increases efficiency due to lack of internal space.

(3) The lubricating oil has functions of sealing, cooling and lubrication of the machine.

(4) Compared to the reciprocal compressor, our air compressor has advantages that it has a low failure rate and less vulnerable parts. In addition, vibration and noise is lower than in other compressors of other manufactures.

(5) It has water and air cooling. The gas compressor cooling system is designed with a fin plate structure. The high quality of the materials provides the compressor with a high heat dissipation rate of the cooling system and makes the cooling system resistant to pressure and corrosion.

(6) The multiple air filter in the air compressor can remove 98% dust (with the accuracy of 1um). It has a large work surface and a long working life.

(7) With the latest materials, the oil / gas separator can achieve a higher oil / gas filtration rate, and the ratio between air and oil is less than 2ppm.

(8) The process is carried out under intelligent control. In the control panel the static ones are shown with precision, which makes the handling of the air compressor more comfortable.

Installation and debugging

1. Choose the most suitable place for the air compressor before installation, because the first key point is to establish an independent air compression center. Experience has shown that using the machine as a set is the best way to carry out an economical operation, comfortable maintenance, and comfortable handling. In addition, air compressor integrity management can reduce noise and help keep the shop ventilated.

2. It is necessary to choose a special area to locate the gas compressor, because the damage caused by noise, machine ventilation and high temperature must be taken into account. In addition, several issues have to be considered, including the discharge of condensate, fuel, harmful substances, the extension of the workshop, the maintenance of the workshop, etc. The air compressor can also be installed outside if there is no room inside the workshop. A protective enclosure for air intake and antifreeze measures for the cooling jacket and the discharge opening will then be necessary.

   Purchase Orders

Clients have to take pressure into account when they are going to buy an air compressor.The diameter of the pipe and the inflection points also have an impact on the pressure. The less diameter and less inflection points, the lower the pressure lost. Therefore, the compressor must be close to the pipes and the diameter of the pipes should be amplified. That is why the pipes should be installed near the compressor as soon as possible.

Two facts to which we must pay attention are volume and flow.

(1) Have a general knowledge of gas volume and flow applications, and then multiply by 120%, the answer will be the data you need

(2) Choose the correct machine according to the data provided by the designers before starting a new project.

(3) Get information about the specifications of the air compressor.

(4) The modification of the gas compressor is based on the original data and demands.

A good compressor choice can benefit the employees and the working time of the compressor. A compressor that is too large can result in a waste of resources. While a compressor that is too small may result in an overload at work or insufficient air supply.

It is very important to control the relationship between power and the other three elements, including working pressure, volume and flow.

If the power is constant, the flow, volume and working pressure will change with the rotation speed change
