Drive Coupling Type Screw Air Compressor

Premium Efficient Motor The motors’ horsepower is extremely strong, lower energy consumption, higher reliability; protection Class is IP54/55, prevents the dust to enter the motor inside, insulation Class is F.

Microprocessor Control System Friendly menu interface, multiple units’ interaction control achieved by RS485 communication interface.

Minimum pressure valve With a most reliable valve, to ensure the required pressure by oil circulation in the compression system and to stop the gas from flowing backwards.

Air Exhaust Over Top Cooling air is from the low lateral part of the unit and the hot air is discharged from the top of the unit with the cooling fan’s rotation, the heat was take off fast away, furthermore the hot air is discharged from the tip the unit to allow convenient recycle and reuse of heat.

Air Filter Special paper air filters can purify the absorbed air, avoiding wearing of the rotor and bearings, extended the life of oil, oil filter and oil separator.

Efficient Separating System Dual oil/air separator ensure the oil carryover is no more 1PPM, meeting the demand of higher quality compressed air, and oil recycling rate so low to ensure the longer service the life and quality of lubricants.

Air END Performance Excellent Efficient Compression The air is the heart of the compressor, which is the base of thigh quality, high efficiency, high reliability of the air compressor. It is the result of the technology and experience.

Perfect Rotor Teeth Profile The rotor adopts the third-generation-symmetric-rotor profile with ratio of tooth numbers being 5:6. This mean less pressure loss and return loss, compared with 4:6 rotor profile, the efficiency is improved 10-20%.

Direct Coupling System The air end and motor is connected with a flexible coupling. This coupling design achieves an efficient transfer of power and the lower energy consumption, which can be called a real sense of 1:1 transmission, not only without any transmission loss, reducing the number of parts and maintenance costs, but also reducing noise level.

Air filter Design from professional manufacturer, have the ability of overload and multilevel high-efficiency.

Driving organization with high-effect and long using year Whether belt drive or spring unite-axis drive the designed using year is twenty-five thousand hours and insure can use until eight thousand hours or above two years.

Inlet Valve With a most reliable vale to automatically adjust the air inflow within 0-100% in accordance with the requirement for air consumption so as to minimize the running cost.

Screw air compressor planning

1. Decision of Pressure

• The higher of pressure, the bigger of electrical consume.
• List the using of pressure, if the difference of using pressure is too big, should purchase air compressor with different pressure or supercharger. Don’t reduce pressure to use. That will increase the electrical consume.

2. Quality and requirement for compressed air

• Compressed air includes so much water, will damage the machine and equipments, water corrupt and jam the machine. User will lose money on service. So should install air clean system

3. The choose of model

• Calculate the total using air and allowance. (THE PRODACT IS PRODUCED ACCORDING TO GB/T15487-1995 STANDARD BY INSPECTION)
• Notice the electrical consume ratio, to save electrical. The air delivery (m³/min) divide horsepower (HP) the ratio is bigger more save electrical.

4. Ground

• Should choose the expense ground with good daylight.
• Low temperature, few fly ash, cleanly air and good aeration.

Frequency converting screw air compressors

The most efficiency of an air compressing system is achieved by ensuring amount of in-flowing air equals to out-flowing air. In a traditional air compressor, this is done by using such as “loading/unloading”, “system on /off”, “in-flow air congestion control” processing methods.

However, the disadvantages of those mentioned methods involve limited adjustable levels, frequent usage of the air value and some electronic components therefore reduced air compressor life-cycle. Aiming on making a breakthrough on the traditional technology, our frequency-controlled air compressor controls the in-flowing air by controlling the rotating velocity therefore it’s rotating velocity of the electronic motor. The varying of out-flowing air now is varying as the adjustable level, also reducing the frequency of turn on /off the air-valve and usage of other electronic elements. Therefore energy efficiency and increased life-cycle are the outstanding highlights of our designed frequency-controlled air compressor.

The frequency of the input pressure can be varied to meet various individual needs. The recommended pressure is normally set to be no greater than the maximum processing pressure which is the unloading pressure. In this case air compressor works more efficiently, with minimized chance of occurring such as lines leakage.

Reduce more than 30% energy consumption

• Accurate pressure-control allow smaller pressure-range
• Reduce the unload loss
• Reduce the running cost of energy and get more benefit
• Avoid conversion loss between load and unload
• Highly improve the efficiency of the compressed air Features
• Install the transducer inside if the air compressor to save space
• No energy loss. No peak value current for constant pressure
• Vector type transducer can make constant
• Low rotating speed. Start without load. High reliability
• The transducer integrate with the PLC easy to operate

Frequency-converting function approved for every type of screw air compressor Frequency-converting function can be activated according to various needs of clients.

We may provide all kinds of frequency-controlled screw air compressor, the power from 5.5 kW to 280 kW, the air delivery from 0.6m³/min to 45m³/min, the pressure from 0.5 MPa to 1.3 MPa, and with water cooling, air cooling, belt drive or coupling.
