Hot selling Screw type Energy Saving 7.5kw 10hp air compressor Industrial Rotary Compressor
Short Description:
The biggest advantage of permanent magnet variable frequency air compressor is energy saving. Generally, it can save energy by 30%~40%. The amount of energy saving depends on the working conditions of the air compressor and the setting of the parameters of the inverter. The biggest factor is the working condition of the air compressor. When the customer’s air consumption fluctuates greatly, the energy saving effect will be better. The most direct data is the proportion of the no-load time to the total working time.

PM VSD air compressor features
1. Fast response to load
The load reaction action is very fast, the traditional screw machine will affect the reaction speed with the change of processing time during the operation, but this new frequency conversion screw machine will not;
2.Low motor friction
In the structural design of the body, there is no bearing, which effectively avoids the friction between the bearing and the rotor, and there is no need to do too much maintenance on the motor during daily use;
3.High transmission efficiency
This variable frequency permanent magnet screw machine has undergone a great change in transmission, and adopts the direct transmission mode to reduce the energy loss during the transmission process, especially when the main engine and the motor are connected together;
The frequency conversion permanent magnet screw machine has fast response speed, low motor friction, high transmission efficiency, and high use value of the body, especially suitable for large factories.
Product Description
The ALANDA permanent magnet variable frequency screw air compressor has energy-saving effect. It adopts the frequency converter of well-known Chinese brand and adopts the high-efficiency energy-saving control system. The software startup of the air compressor reduces the electrical shock to the electrical components of the motor, and the startup current is small, which prolongs the The life of the motor’s contactor.
The software start of the air compressor reduces the mechanical shock to the equipment, and the motor bearings, main engine bearings and gearboxes all prolong the service life. The high-efficiency and energy-saving controller control device keeps the air compressor in a loaded state most of the time, and all kinds of related solenoid valves and pneumatic components greatly reduce the number of actions, so the failure rate of electrical and mechanical parts is greatly reduced. Feeds the cost of replacement parts and labor. In addition, the inverter control device keeps the air compressor in the loading state most of the time, and the air inlet filter is always in the forward filtering state. When unloading, the air filter is in the reverse filtering state, and the use of the inverter is greatly reduced. It shortens the reverse filtration time of the inlet filter and prolongs the service life of the filter element.
