What Ampere fuse (A) is needed?
At 575 volts, a 3-phase motor draws 1 amp per horsepower.
At 460 volts, a 3-phase motor draws 1.27 amps per horsepower.
At 400 volts, a 3-phase motor draws 1.5 amps per horsepower.
At 230 volts, a 3-phase motor draws 2.5 amps per horsepower.
At 230 volts, a single-phase motor draws 5 amps per horsepower.
At 115 volts, a single-phase motor draws 10 amps per horsepower.
These numbers above have no safety margin. For example, a 10hp compressor=15A and the standard fuse size is 16(A). To be safe for peaks we recommend the 20(A) fuse. Please check with a certified electrician.
In order to ensure that our screw compressor operates as efficiently as possible, Jinjing has independently developed its own special rotor profile. Compared with other traditional rotor profile designs, Jinjing rotor can save up to 15% energy.
Our precision machined large-size roller bearings help to make our air end have a long service life. All these, together with our state-of-the-art internal manufacturing processes and strict manufacturing tolerances, provide excellent quality synonymous with the Jinjing name.
Jinjing adopts an international advanced frequency conversion module, a special motor with speed up and down characteristics, and a set of PID parameters especially suitable for screw compressors. The control software has been tested by hundreds of thousands of compressors, with simple parameter settings and a friendly man-machine interface. The cooling of the frequency converter is specially designed. In order to support the user to set the best working pressure, the filtering area of the filter element of the oil-gas separator is increased.
