Product Description Product Description 60 HP Double Stage Rotary Screw Air Compressor Supplier in ChinaPermanent magnet variable frequency two stage screw air compressorThe two-stage compression screw variable frequency air compressor combines the advantages of two-stage compression technology and variable frequency control, and has outstanding performance in energy efficiency, stability, life and applicability. The following are its main advantages and characteristics:1. Ultra-high energy efficiency, significant energy savingTwo-stage compression optimization: The air is compressed in two stages (low pressure stage + high pressure stage), and the cooler is used in the middle to reduce the compression power consumption, which saves about 15%~20% energy compared with single-stage compression.Variable frequency regulation: The variable frequency drive (VFD) adjusts the motor speed in real time according to the gas demand to avoid unloading waste, especially in scenarios with large load fluctuations (such as intermittent gas use), which can save 30%~50% energy.2. More stable air pressure and air supply qualityConstant pressure output: Variable frequency control realizes precise pressure regulation (±0.1 bar), avoids air pressure fluctuations, and meets the needs of precision manufacturing, electronics, etc. that are sensitive to air pressure.Low temperature operation: Two-stage compression reduces the single-stage compression ratio, reduces the heat load of bearings and rotors, extends the life of lubricants, and reduces high temperature failures.3. Long equipment life and low maintenance costLoad balancing: Two-stage compression shares the compression ratio, reduces the mechanical stress of single-stage bearings and rotors, and extends the life of core components (such as screw main engine).Soft start protection: The variable frequency starting current is small, which reduces the impact on the power grid and mechanical components, and reduces the wear of the motor and transmission system.4. Low noise and environmental protectionVariable frequency noise reduction: The noise is significantly reduced when running at low speed (10~15 decibels lower than the industrial frequency machine), which is suitable for quiet environments such as hospitals and laboratories.Emission reduction effect: High efficiency and energy saving reduce carbon emissions. Some models use environmentally friendly lubricants (such as synthetic esters) to reduce environmental pollution.5. Wide range applicabilityHigh pressure demand: Two-stage compression can easily achieve high pressure output (such as above 1.3MPa), which is suitable for high pressure scenes such as laser cutting and CNC processing.Adaptation to variable working conditions: Variable frequency technology is compatible with continuous adjustment from low load to full load, and can cope with seasonal or gas consumption fluctuations.6. Intelligent controlRemote monitoring: integrated intelligent controller, supports Internet of Things (IoT) access, real-time monitoring of energy consumption, fault warning, and optimization of maintenance cycle.Multi-machine linkage: can be combined with multiple air compressors to form an intelligent joint control system, start and stop on demand, and further improve energy efficiency.Typical application scenariosHigh-energy-consuming industries: continuous production fields such as automobile manufacturing, metallurgy, and chemical industry.Precision industries: semiconductors, medicine, and food processing (oil-free models are required).Fluctuating load scenarios: intermittent gas-using equipment such as injection molding machines and textile machinery.Technical ParametersTwo-stage PM VSD Screw Air CompressorModelAir Delivery (m3min)Power(kW/hp)NoisedB(A)OutletdiameterDimensions(mm)Weight(kg)7 bar8 bar10 bar13 barL*W*HRK30APMI1.4-4.51.3-4.21.1-3.50.8-2.7 22/3068 G1121350*850*1110600 RK40APMII1.8-6.01.7-5.91.4-4.7 1.2-4.0 30/4068 G1121200*1000*1350700 RK50APMII2.3-7.52.1-6.91.8-6.0 1.6-5.4 37150 68 G1121500*1000*1350750 RK60APMII3.2-10.53.0-9.92.3-7.8 2.0-6.8 45/6072 G22100*1300*16501250 RK75APMII4.1-13.63.8-12.53.0-10.1 2.3-7.5 55175 76 G22100*1300*16501300 RK100APMII4.8-16.04.7-15.53.8-12.83.1-10.2 75/10076 G22100*1300*16501350 RK125APMII6.2-20.75.9-19.54.8-16.24.2-14.0 90/12576 DN802500*1650*19002700 RK150APMII7.4-24.87.2-24.06.1-20.24.8-16.0110/15076 DN802500*1650*19002800 RK175APMII8.7-29.08.4-28.07.1-23.75.7-19.0132/17578 DN802500*1650*19003000 RK220APMII10.2-34.09.8-32.58.4-28.06.9-23.0160/22078 DN803000*1900*19504300 RK250APMII11.7-39.010.8-36.09.6-32.08.3-27.5185/25078 DN803000*1900*19504400 RK275APMII13.1-43.512.3-41.010.7-35.59.5-31.5200/27578 DN1003600*2200*22005000 RK300APMI15.5-51.514.5-48.311.6-38.510.7-35.5220/30082 DN1003600*2200*22005500 RK350APMII16.2-54.015.3-51.013.5-45.011.4-38.0250/35082 DN1003600*2200*22006000 RK375APMII18.0-60.017.1-57.015.0-50.012.9-43.0280/37582 DN1253600*2200*22006800 RK420APMI19.5-65.018.6-62.016.8-56.015.2-50.5315/42082 DN1254200*2300*23508000 RK480APMII22.5-75.021.9-73.019.2-64.016.5-55.0355/48082 DN1504200*2200*23508500 RK540APMII25.2-84.024.6-82.021.6-72.018.3-61.0400/54082 DN1504200*2200*23509800 CertificationsPackaging & Shipping1.Packing Details: Plywood crate pallet plus foam board and bubble film, Full closed wooden case. 1pcs/each package (for stationary screw air compressor)2.Shipping method: by sea, by LCL/FCL or as requested3.Delivery method: FOB, CFR, CIF and EXW etc.4.Delivery time: in 7-15 days after receiving deposit (customized machines not included)Successful casesCompany ProfileShanghai Rocky Machinery Co., Ltd. was established in 2003 and has 18 years of experience in the air compressor industry.
