Oil-free Screw Air Compressor
BESTRAND oil-free screw compressor adopts a water lubricating screw unit developed with European technologies. Being resistant to corrosion, it's free ofdeformation in high and low temperature environments, and a separate lubricating watercourse is adopted inside to minimize abrasion ofthe main unit and reduce air pollution.
With a higher air flow velocity, it adopts original water separation and softening systems imported from Germany to increase the water separation speed inside the vapor bucket, yield the best water separation effect and make sure ofa water content in the exhaust being less than 2mg/m3. Itadoptsthecopperscrew andsealingmaterialsimportedfromDOS.DSso thatthescrew'ssealingandengagementare tighter and the sealing materials are more anti-wear. It adopts imported SKF bearings plus the separate internal hermetic seal technology to guarantee absolutely zero contact between lubricating water and bearings, reduce rustiness ofbearings caused by lubricating water and make sure ofthe service life ofbearings exceeding 50,000hours. Its water system adopts the unique water filtration and lubrication system ofGerman DOS.DS to make the best use oflubrication, sealing ,noise reduction and cooling functions. The full automatic water control system ensures reasonable water flow and reduces the compressor's power loss. It adopts a design ofdouble systems: air and water cooling, to ensure easy use and installation for customers. It all adopts direct connection transmission with the lowest
power consumption.
