Two Stage Permanent Magnet VSD Electric Direct Driven Rotary Screw Air Compressor

Efficiency Saving Energy Air End Screw

The air end features a big rotor with a low speed and two independent compression units.

High efficiency and dependability Low vibration and low noise. Per stage, there is a low compression ratio. Volumetric efficiency is improved. Leakage is reduced. The shaft bears less

force and has a longer life since the same power is used by two heads to bear the load.

The air end has a large rotor that rotates slowly and comprises two separate compression units, it has a high efficiency, low noise, low vibration, and high reliability, as well as a low

compression ratio in each stage, reduced leakage, and a higher volume efficiency. Two units take the load under the same power, reducing the stress on each bearing and extending the

life of the part.

Permanent magnet motors that save energy

The main motors are energy efficient IP54 rated permanent magnet motors that have been carefully chosen to meet the needs of the air compressor application, all of which meet national level energy efficiency standards, torque, and load to meet specific design criteria in order to optimize motor efficiency and power factor under load conditions. Other motor efficiencies are about 5-8 percent better than this optimum factor.

Oil separation system with high efficiency and low energy consumption

Oil filter, low pressure drop design, service life of up to 4000 hours, high filtration accuracy to effectively protect the bearings and screw machine rotor, high efficiency oil and gas separator, special simplified design, aggregated separation core and the composition of the oil return device, service life of 6000 hours, oil filter, low pressure drop design, service life of up to 4000 hours, high filtration accuracy to effectively protect the bearings and screw machine rotor Air filter, no need to alter air flow direction when filtering, air flows directly through the filter media, reducing pressure loss, more energy efficient than standard air filters, larger filter area, higher precision, longer life.

The cooling system is well-designed.

Adopt a high efficiency warp type large area heat exchange cooler with a 30% heat exchange surplus for greater cooling effect and the ability to work normally in temperatures as low as 45°C.

Double-stage compressor with permanent magnets

When compared to standard industrial frequency machines, the new energy-saving setup saves 35% on electricity.

Mainframe with two compression stages

When compared to a regular frequency machine, it is more efficient and saves energy by 35 percent.

With 8000 hours each set per year, it may save around 200.000CNY in annual electricity costs.

Features of the permanent magnet double-stage compressor

1. Two-stage compression lowers each stage`s compression ratio: minimizes internal leakage, increases volumetric efficiency, lowers bearing load, and extends the life of the main engine.

2. When two-stage compression is used instead of single-stage compression, the exhaust volume increases by roughly 15%, resulting in a 15% improvement in energy savings.

3. The rotor uses the most up-to-date design of the rotor UV patent profile, which has through more than 20 stages of finishing to ensure the rotor profile`s precision, dependability, and efficacy.

4. The double-stage compression mainframe is more efficient and energy-saving than the ordinary frequency machine, saving up to 35% energy and saving 200.000CNY in annual electricity costs with 8000h/set/year.
