6.5 Air Filter/Regulator and Lubricator Precautions
CAUTION
Failure to follow the following precautions
and instructions could allow the air filter/regulator and/or
air lubricator bowl to rupture. Minor or moderate personal
injury could result:
• The bowls of the air filter/regulator and air lubricator
are made of a durable thermoplastic material.
• To prevent the bowls from becoming cracked or
damaged, avoid the use of chemicals or solvents
(either in the airflow or used as cleaning agents). Use
only mild soap and water for cleaning.
• Consult the manufacturer of the air filter/regulator
and air lubricator for additional information if you are
uncertain if substances present in the compressed
air system or work environment will be harmful to
these components.
CAUTION
Always shut off compressed air supply and
disconnect air hose from pump before removing the air
filter bowl or air lubricator bowl for any reason. Failure to
follow this instruction will result in the uncontrolled release
of pressurized air or air lubricant oil. Minor or moderate
personal injury could result.
6.6 Air Lubricator - Adding Air Lubricant Oil
The air lubricator injects oil into the compressed air stream,
providing lubrication for the pump air motor. See Figure 6.
Air lubricant oil (user-supplied) must be added to the air
lubricator before pump initial start-up.
The recommended air lubricant is a petroleum based oil of
100 to 200 SUS viscosity at 100°F. [38°C] and an aniline
point greater than 200°F [93°C]. Do not use alcohol or
ethanol based lubricants as these may cause damage to
lubricator components.
Add oil to the air lubricator as described in the following
steps:
1. Shut off compressed air supply. Disconnect air
supply line from air inlet connection on pump.
2. Remove the fill plug at the top of the air lubricator.
3. Slowly add air lubricant oil as required. See oil level
graphic in Figure 6.
• To prevent spillage, use a funnel or a bottle with a
long spout. Fully insert end of spout or funnel into
the recessed area of the lubricator oil fill port.
• The air lubricator is completely filled when the oil
level is up to - but not above - the top window of the
lubricator bowl. DO NOT OVERFILL!
4. Reinstall the fill plug after adding oil.
NOTICE
DO NOT OPERATE PUMP WITHOUT AIR
LUBRICATION. Maintaining the oil level in the air lubricator
is critical to the life of the air motor.
The air lubricator must be periodically refilled with the
proper lubricant BEFORE it becomes empty. Premature
air motor wear will occur if pump is operated without air
lubrication.
To ensure adequate air lubrication, also be sure that the
air lubricator oil drip rate is properly adjusted as described
in Section 6.7 of this manual.
