Product Usage Instructions
What is Air-Lock?
Air-Lock protects oil drums against contaminant ingression
during storage. It prevents contamination by increasing headspace
air pressure, acting as a barrier against contaminants. The yellow
fluorescent indicator shows a good seal and maintained
pressure.
Features
- Fluorescent yellow indicator for easy visibility
- Sight Glass Vent
- Eyelets to attach ID tags and other information
- Hex design for easy installation
- Relief Valve to prevent over pressurization
- Schrader Valve for pumping air into the drum
How to Use Air-Lock
Check Air-Lock daily to ensure the drum remains sealed. If the
yellow indicator is visible, the drum is sealed and protected. If
not visible, increase pressure using compressed air through the
Schrader Valve. Stop pressurizing five seconds after the indicator
stops rising. Air compressor regulator must be set to 100 psi or
less.
How to Remove Air-Lock
Air-Lock should only be removed when the drum is not
pressurized. Rotate Air-Lock 1/2 turn counterclockwise to relieve
air pressure. Wait until the sound of escaping air stops before
removing Air-Lock.
Warnings and Disclaimers
Do not remove the drum lid, bung plugs, or Air-Lock while
pressurized. Do not use Air-Lock with water-filled drums. Do not
block the relief valve or vent.
FAQ
What is the purpose of the fluorescent indicator on the
Air-Lock?
The fluorescent indicator helps users easily identify if the
drum is properly sealed and if pressure is being maintained.
Can Air-Lock be used with any size of oil drum?
Air-Lock is designed for drums with a male thread size of NPT 2,
which is a typical drum bung thread size.

Air-Lock protects oil drums against contaminant ingression during storage.
Temperature changes frequently cause breaches in drum seals allowing
contaminated air (particles and moisture) to enter the drum headspace. Such
contaminants during storage harm additive packages, increase oxidation, and
leads to higher filtration costs. Air-Lock’s patented design prevents
contamination by increasing the headspace air pressure, which acts as a
barrier against contaminants. Air-Lock also features a yellow fluorescent
indicator to indicate a good seal, and that pressure is maintained. Stop
contamination with confidence and get Air-Lock today.

Threads 2″ NPT
· For use on 55-gallon steel drums that are in good condition and capable of
holding air pressure.
· Do not remove the drum lid, bung plugs, or Air-Lock while the drum is sealed
and pressurized. There may still be pressure even though the Indicator is not
visible.
· Do not use Air-Lock if ambient temperatures are greater than 200°F (93°C) or
if ambient temperature fluctuations are greater than 75°F (24°C).
· Do not use Air-Lock with a drum desiccant breather, pump, or filter cart. ·
Do not expose Air-Lock to chemicals not compatible with Tritan® or Viton®. ·
Do not clean Air-Lock with high-pressure water. · Be careful not to damage or
puncture the Diaphgram at the bottom of Air-Lock. · Do not plug or block the
relief valve or sight glass vent. · Visit Luneta.com for more details.

Installation Instructions
· Steel drums typically have two openings (bungs holes), one with a 2″ plug
and another with a ¾” plug.
· To install Air-Lock, remove the existing 2″ bung plug and replace it with
Air-Lock. Do not use thread sealing tape or other sealers on the Air-Lock
threads.
· Tighten Air-Lock by hand or wrench until the O-ring is fully compressed. Do
not tighten more than 12 ft-lbs. Do not use the schrader valve as leverage.
· Check to ensure the ¾” bung plug is tight and sealed. · Attach an air
compressor to the schrader valve and pressurize the drum.
The air compressor regulator must be set to 100 psi or less. · The yellow
fluorescent indicator will begin to travel and become visible
when the headspace pressure reaches 1.0 psi. The indicator will stop and reach
its limit at 1.5 psi. · STOP pressurizing five seconds after the indicator
stops rising, or when the headspace pressure is around 2.5 psi. · As a safety
measure, the relief valve will open at 4 psi. Do not use the relief valve as a
stopping point. · Check for audible leaks. If you hear escaping air, follow
the air leak instructions below. · Wait a few minutes to check and ensure the
indicator doesn’t drop back down. If the indicator remains visible, the drum
is now sealed and protected from contamination. · If the indicator drops back
down, see the air leak instructions below. · Attach the included drum lid
decal to the drum lid next to the Air-Lock for future reference.
Solving Air Leaks
If the indicator drops back down or you hear escaping air, there is an air
leak. If the leak location is unknown, use soapy water and look for bubbles.
Below is a list of possible leak locations: · Relief Valve. Wait several
minutes until the pressure drops below the
reseal pressure of the valve, or 3 psi. · O-ring. Tighten Air-Lock by hand or
with a wrench. Do not tighten more
than 12 ft-lbs. Do not use the schrader valve as leverage. If this doesn’t
work, relieve the pressure, remove Air-Lock, and inspect the O-ring and
sealing surface. · Schrader Valve. Tighten the valve with a 13mm wrench. Do
not tighten more than 18 in-lbs. · ¾” Bung Plug. Tighten the plug. If this
doesn’t work, relieve the pressure, remove the plug, and inspect the plug
gasket and sealing surface. · Open Head Drum Seal. Tighten the bolt or lever
lock ring closure that secures the lid to the barrel. If this doesn’t work,
relieve the pressure, remove the drum lid, and inspect the gasket and sealing
surface. · Sight Glass Vent. Contact Luneta for further instructions.
How to Use Air-Lock
· Check Air-Lock daily to ensure the drum remains sealed against outside
contaminants.
· If the yellow indicator is visible, the drum is sealed and protected. · If
the yellow indicator is NOT visible, the drum is not sealed, and action
must be taken to increase the pressure and/or investigate why the pressure
dropped.

Removal Instructions
· Air-Lock will need to be removed to access the oil in the drum. · Never
remove Air-Lock while sealed and pressurized. There may still be
pressure even though the indicator is not visible. · To relieve air pressure,
rotate Air-Lock 1/2 turn counterclockwise and
wait until the sound of escaping air stops. Only then is it safe to remove
Air-Lock.
