Air Requirements - WORKMASTER GO-A8-PW Operator's Manual

V. AIR REQUIREMENTS
An Air Compressor of sufficient capacity is needed to provide the necessary air
volume (CFM), at the most efficient operating pressure (PSI), to ensure effective
and economical operation of the GO-A8 Opener.
IMPORTANT
1. Air Pressure of 85 to 90 PSI is recommended for maximum performance.
This setting represents required
at the Compressor. There is always a pressure drop between the
Compressor and the Opener; only the pressure and volume at the Opener
is effective in doing work. If the hose is relatively short (25' to 50'), and
in good condition, the pressure drop between the Compressor (or Air
Receiver Tank), and the Opener should not exceed 15% of initial
pressure. Adjust Compressor output to compensate for drop.
2. Clean, moisture-free, lubricated air should be delivered to the Opener at
all times. The air line delivering air to the Opener should be equipped
with a coalescing type filter/dryer to collect and remove moisture and
contaminants.
3. Quality air hose designed especially for heavy-duty service should be
used. It should be constructed with an outer covering that resists
abrasive wear, an oil-resistant inner tube, and should be able to withstand
temperature extremes. It should have a working pressure of at least
200PSI.
4. All hose couplings and fittings between the compressor and the Opener
should be full bore type, be in good condition, securely attached, and kept
as tight as possible (check Coupling gaskets). Elimination of air leaks
involves making the air system tight and then keeping it tight. At a typical
unloading site, air losses through bad connections, too many connections
and worn hose often reaches 25% of the total air compressed.
Low or inadequate air pressure at the opener is costly
and wasteful. An insufficient air volume will not allow
the GO-A8 Opener to operate effectively.
