The supply of clean, dry air is essential to the operation of
pneumatic powered tools. Use only clean filtered air for
longer tool life. Provide proper airflow (CFM) and regulate
air pressure (PSI) for optimum performance.
Air Preparation Units: Basic Functions
To determine unit size for application, you need to know:
PRESSURE VESSEL
• Total air flow (CFM) required for application
Contaminated
compressed air
- oil water, solids
(scale, etc.)
Stored compressed air,
oil-water emulsion from
condensate and
lubricating oil
LUBRICATOR
LS
IN/MM
• Size of incoming air line and size of air line required
by tool
FILTER
REGULATOR
• Air supply pressure (PSI)
• Allowable pressure drop
Clean, regulated,
and lubricated
compressed air for
AIMCO tools
Clean, dry
compressed air,
regulated at
desired pressure
Clean
compressed air
with pressure
fluctuations
• Does the application require lubrication?
• Does the overall system have the required capacity?
