I am setting up my compressors in a new location. I have three phase 380 volts outside my door, but they want $3000 to run the wire ! UNBELIEVEABLE....there was another dive shop here, and they moved 5 times at $3000 a pop for the three phase....
I want to swap over to 220 single, which is household current here.
My compressor has a 112M frame 5 h.p. 3 phase 380 volt motor. Manufacturer says I need 4 KW.
I have found a replacement 112M 1 phase 220 volt motor rated at 3.7 K.W.
The compressor is good for 300 bar, but I have down rated it to 220, as we only fill Al 80`s with it.
I am having a very hard time determining if they use the same motor for the 300 bar and 200 bar versions. The manufacturer is of no help.
If indeed they use the same motor.....will the 3.7 K.W. (Draws 26 Amps) be adequate to pump 220 bar ?
If not I have to make a jump up in frame size, and I will have to remachine the pulley to accept the shaft.
This unit delivers quite close to 200 l/min.
BTW this motor is costing me $190 !!!!!
1 year guarantee, TEFC, 1.15 load factor, dual ball bearing, continuous compressor rated. 45* C. 1,200 mFD capacitors....92 pounds !
Original motor was 1350 rpm, the new is 1450.
Next question...I am aware that moisture is the enemy of a filtration system.......I have available to me second hand Hitachi air dryers. I can get a 400 lit/min for about $300.
Is it worth drying the air ? I know there is massive moisture removal during compression, but how will it effect my filter life if my intake air is humidity is reduced from 90 % at 30 *C ( Dew Point about 28*C ) to an outlet dew point of 10* C ?, or about 30 % R.H at 30 *C . If I understand all that I am learning correctly.....
