GAS SUPPLY REQUIREMENTS
The gas supply for the Powermax900 can be either air or nitrogen. Air can be supplied as shop
compressed air or cylinder compressed air. Nitrogen can be supplied from compressed gas cylinders
or liquid containers. A high-pressure regulator on either type of supply must be used and must be
capable of delivering the following:
360 scfh/6 scfm (170 l/min)
at a pressure of
90 psi (6.2 bar)
to the filter on
the power supply.
The filter is mounted at the rear of the Powermax900 power supply. See Fig. 3-12.
WARNING
Do not allow the gas inlet pressure to the filter on the power supply to exceed 120 psi (8.2
bar). The plastic filter bowl is rated for 150 psi (10.3 bar) and may explode if this pressure
is exceeded. See the label on the filter bowl for other safety warnings.
Air Supply Quality
The cylinder or shop compressed air supply must be clean, dry and oil-free. If air supply quality is poor,
cut speeds decrease, cut quality deteriorates, cutting thickness capability decreases, and parts life
shortens.
Additional Air Filtration
Use a three-stage coalescing filtration system as shown in Fig. 3-11 when site conditions introduce
moisture, oil or other contaminants into the air line.
Nitrogen Quality
Nitrogen must be supplied to the Powermax900 at 99.995% purity. If the purity level of the nitrogen is
too low, cut speeds decrease, cut quality deteriorates, cutting thickness capability decreases, and parts
life shortens. (Note: These conditions also occur if there are leaks in the gas supply hoses or
connections.) The nitrogen supply can be compressed gas cylinders or liquid containers.
