Key features

Oil cooled IP65 PM motor with VSD cuts energy 30 to 45 percent versus fixed speed units, removes no load loss, and survives dusty 45 degree tunnel and quarry sites where air cooled motors overheat.

12.3 to 13.5 m3/min at 8 bar steady output feeds 4 to 6 jack hammers or 1 to 2 light rock drills simultaneously, pressure held within plus minus 0.01 MPa by inverter control for consistent chisel impa

Direct coupled IE4 drive, G2 outlet, soft VSD start avoids peak current and star delta wear, runs 68 to 72 dB(A), no foundation needed, 380V/415V/440V/60Hz customizable for export jobsites.

Product Q&A

Q:Q1: What is the real air flow at 8 bar for this 75 Kw PM VSD unit?

A: About 12.3 m3/min at 8 bar, 11.6 at 10 bar, 10.2 at 13 bar per ISO 1217. VSD modulates 30 to 100 percent of this range to follow jack hammer duty cycle.

Q:Q2: Why oil cooled PM motor instead of air cooled for jack hammer use?

A: Tunnel and quarry sites have silica dust and 40 to 50 degree ambient. Oil cooling circulates compressor oil through motor jacket, keeping magnet under 120 degree and IP65 rating blocks dust entry. Air cooled PM motors demagnetize faster in such sites.

Q:Q3: Can it run 4 jack hammers at once?

A: Yes. A single 5/8 inch jack hammer consumes 0.9 to 1.2 m3/min at 6 to 7 bar. 12.3 m3/min supports 4 to 5 hammers with margin for hose loss. For 6 plus tools pick 90 to 110 Kw class.

Q:Q4: What voltage and start method are standard?

A: 380V/50Hz/3phase VSD soft start standard. Custom 415V/50Hz, 440V/60Hz, 460V/60Hz with ABB or Inovance inverter. No star delta, no contactor wear.

Q:Q5: Is stationary only or can it be skid or trailer mounted?

A: Base model is stationary with lift eyes. Optional skid frame with drag hooks or trailer chassis with lights and brakes for jobsite move between tunnel faces.
