Kaishan Compressors has introduced a high-performance double screw blower for Australian industry wanting a high efficiency, energy saving, low noise blower for critical contamination free applications. The advanced JNb series of lubricantil free rotary screw blowers adopts a patented, double screw rotor profile with 6-4/5-3 male and female rotors. The advanced air end utilizes a pair of high precision, synchronous gears for the meshing operation.
The blower includes a Y-4 profile double screw rotor; The Vi design includes multiple pressure ratios. For different discharge pressure applications. Pressure ratios are configured to achieve the maximum efficiency.
The intake, exhaust noise reduction technology and fully sealed noise enclosure ensure the noise level meets international standards.
With balanced power operation the blower can be easily installed without special foundations.
Frequency converter adjusts air volume to meet demand thereby reducing energy usage.
With a dedicated microprocessor providing frequency conversion, interlock and air output variation, operation is easy to control and manage either remotely or at the machine.
Compared with a Roots blower*, the energy saving ratio of an Oil-free rotary screw blower increases with the increase of operating pressure. Screw blowers operate at considerably lower temperatures and the sealed bearings remove the need for lubricants in the air end.
*Roots type blowers are commonly referred to as air blowers or positive displacement blowers
