2.4. Compressed Air & Gas
The plasma torch requires clean, dry, oil free air, i.e. it must be filtered. Poor
quality air will reduce cutting speeds, produce poor cut quality and reduce
torch parts life. Ensure that adequate air supply is available for stable
operation. Air must be delivered at the pressure and flow rate specified.
CAUTION: Do not use any quick disconnects in the air supply line to the
machine as these have small flow areas that will restrict the air
flow rate to the machine.
2.4.1. Gas Supply Requirements
Gas Supply: Clean, dry, oil-free air
Air inlet pressure for machine: ................................................80-110 psi
Gas inlet flow rate/pressure for Hypertherm plasma systems:
Powermax 45 ............................................. 360 scfh; 6.0 scfm @ 80 psi
Powermax 65 ............................................. 400 scfh, 6.7 scfm @ 85 psi
Powermax 85 ............................................. 400 scfh, 6.7 scfm @ 85 psi
Powermax 105 ........................................... 480 scfh, 8.0 scfm @ 85 psi
Powermax 125 ........................................... 550 scfh, 9.2 scfm @ 85 psi
2.4.2. Option A: Air Dryer Unit
(Piranha Part Number 230579 or equivalent)
Piranha recommends using a stand-alone air dryer unit that consists of a
water-oil-separator and a post filter for the plasma system to protect your
machine. Piranha offers a dryer / filter combination.
2.4.3. Option B: Three-Stage Filter System
(Piranha Part Number 230634
or equivalent)
This option uses a series of three different filters to remove moisture, oil, and
particulate. The filtration should be located as close to the machine as
possible. An outlet valve should be installed to isolate the air supply.
Using this option requires more maintenance than the air dryer option since
there are three different filters to monitor and maintain.
