Screw Compressor ( OGLC 250A)Specifications: Displacement / discharge pressure ( m3/min.Mpa-1 )45.0 / 0.7Transmission wayshaft coupling transmission42.0 / 0.8Air Supply Oil Content ( PPM ) ≤338.0 / 1.0Caliber to take over ( Ømm ) 10033.0 / 1.3Cooling fan power ( KW )4.0×2Gas temperature ( )≤Ambient temperature +15SizeLight ( mm )3085MotorPower ( KW/HP )250 / 340Width ( mm )2050Speed ( r/min )2970Height ( mm )2200Way to startY-starWeight ( Kg) 5440Voltage( V )380Noise [dB(A)]±275Features :1.Rational Structure The star wheels are paired on both sides of the screw shaft to counteract the radial force acted on the shaft and the axial force on the channel by air. Hence the screw is free from any radial or axial force to achieve the absolute balance status. 2.High-efficiency While running, each screw works twice per rotation so the channel space is fully utilized to achieve more exhaling volume compared with the same structural & dimension air compressor. The screw slot depth of screw decreases with the increase of pressure. When exhaling finishes and the star wheel separate from the screw slot, the depth is zero without any clearance volume, then high volume efficiency is achieved. As apply unloading device and servo automatic air volume adjustment, the energy save effects is significant which as much as more than 60% of lower consumption when running at no load. 3 .No Vibration and Low Noise As every rotation of the screw results in 12 compression cycles with 35280 times of exhaling per minute to achieve dynamic balance running, the exhaling process is free from pulses, so the machine vibration is close to zero that a coin can stand still on a running machine. In addition the adoption of sound eliminator and isolator reduces the noise level considerably lower than the other brands of air compressors. 4.Extended Maintenance Cycle Free from any radial or axial forces and pressures in the air compression process, the shaft life of the air compressor can be as long as 50,000 hours, overcoming the easy wearability of the bearing and shaft seals of double screw air compressor, extending the maintenance cycle, and its durability exceeds other counterparts.5.high reliability The star wheels of air compressor is made from PEEK materials, which has been proved of its high reliability in terms of air quality, energy saving, continual running, and low maintenance etc. over the years.We are a professionalAir compressormanufacturerin Shanghai,China , Wesupplysingle screw air compressors,water-cooled compressors,air-cooled compressorand accessories parts etc.Our products have been exported to Europe ,America ,Africa and Australia and so on .We adopt perfect quality management system and have passed ISO9001-2000 quality control system & ISO 14001: 2400 environment systems .
