15KW 20 HP 80 CFM Rotary Screw Air Compressor For Sale

Compared with the power frequency air compressor, it can generally save energy by 10%~35%. Of course, how much energy is saved depends on two aspects. That is, the working conditions and the setting of the parameters of the inverter. The biggest factor is the working condition of the industrial air compressor. When the customer’s actual air consumption fluctuates greatly, then the energy-saving effect will be better. The direct data is the ratio of the no-load time to the total working time.

The soft start of the air compressor reduces electrical shock to the motor components. The starting current is small. Therefore, it extends the lifetime of the motor. At the same time, it also reduces the mechanical impact on the equipment. Correspondingly, it improves the service life of motor bearings, main engine bearings, and gearboxes.

In addition, the energy-saving controller keeps the air compressor in a loading state most time. It reduces the action number of both solenoid valves and pneumatic components. Therefore, the failure rate without these accessories becomes lower. Moreover, the reverse filtration time of the inlet filter is greatly reduced. It extends the filter lifetime of a 20 hp screw compressor.

When the exhaust air volume decreases, the speed of the compressor motor slows down. So the noise is much less than when running at full speed. The unloading run time becomes less, venting noise is also reduced.

Permanent magnet motors can maintain extremely high motor efficiency at low speeds. At the same time, it allows the max speed to exceed the upper limit of the rated speed. Therefore, the adjustment range of exhaust volume can reach 15%-115% of the rated flow. So the application of a 15 kw air compressor will be more flexible.

Belt drive efficiency is typically 0.94 – 0.96. Our 7.5 hp 5.5 kw screw compressor is belt drive type. In addition, the direct drive efficiency is above 0.99. This 20 hp rotary screw air compressor is a direct drive type. The permanent magnet motor does not have any mechanical friction loss or transmission loss. The transmission efficiency is 1.

It can filter out dust and other dirt in the air. The best time for maintenance is once a week. The specific method is as follows: Firstly, take out the air filter of 20 hp screw compressor. Then use a certain amount of compressed air to blow the inside out. Clean up the dirt on the surface of the part. Finally, wipe it clean with a clean cloth.

For the new 15 kw air compressor, replace the oil filter after use for more than 500 hours. After that, we can change it every 2000 hours or so.

The best replacement time is around 3,000 hours. But in the case of relatively bad conditions, it is necessary to shorten the replacement time. At the same time, we need to take the oil separator out in due course for cleaning.

The quality of lubricating oil directly determines the performance of the oil-injected screw compressor. Good oil can make the machine run normally and efficiently. And for a new industrial compressor, it is best to replace the oil after 500 hours of use. After that, we can replace it after every 2,000 hours.

The cooler can cool down and dissipate heat. After long use, the 15 kw air compressor will become hot. If there is a problem with the cooler, the screw compressor will collapse. In addition, the air cooler has a special structure. This makes it prone to dust accumulation. So it is necessary to regularly clean the dust.
