HIGH LIFT REVERSIBLE DRUM VAC
INSTALLATION & MAINTENANCE
COMPRESSED AIR LINE SIZES
Compressed air lines should be sized to hold pressure drops to a minimum. When installing supply lines, use 1/4" pipe
up to 25' (7.6m) long, 3/8" up to 50' (15.2m) long. Compressed air hose (not included) should be 3/8" I.D. up to 25'
(7.6m). Do not use restrictive fittings such as quick connects that can “starve” the High Lift Reversible Drum Vac by
causing excessive line pressure drop.
COMPRESSED AIR SUPPLY
The High Lift Reversible Drum Vac uses normal shop air supplies of up to 100 PSIG (6.9 BAR, 689 kPa). With proper
filtration and separation of dirt, moisture and oil from the compressed air supply, the Reversible Drum Vac will run for
years with no maintenance required. Maximum pressure is 120 PSIG (17.2 BAR, 1.72 MPa).
Use a 10 micron or smaller filter separator on the compressed air supply (Model 9001 Automatic Drain Filter Separator
not included). To prevent problems associated with oil, use an oil removal filter (Model 9006 Oil Removal Filter, not
included). The oil removal filter should be used downstream from the automatic drain filter separator. Filters should be
used close to the High Lift Reversible Drum Vac, within 10 to 15' (3 to 4.6m) is best.
If air preparation units other than EXAIR models are being used, please note the following:
PRESSURE REGULATORS – Must be pressure relieving and rated for a supply pressure of 250 PSIG (17.2 BAR,
1.72 MPa). Suggested operating pressure is 5-125 PSIG (0.3-8.6 BAR, 34-862 kPa). Flow should be minimum 24
SCFM (680 SLPM).
AUTO DRAIN FILTER SEPARATORS – Must be rated for a supply pressure of 250 PSIG (17.2 BAR, 1.72 MPa)
and have 5 micron filtration. Flow should be minimum 24 SCFM (680 SLPM).
OIL REMOVAL FILTERS – Must be rated for a supply pressure of 250 PSIG (17.2 BAR, 1.72 MPa) and have
0.03 micron filtration. Flow should be minimum 24 SCFM (680 SLPM).

USING THE HIGH LIFT REVERSIBLE DRUM VAC
Use a drum that is in good condition and is free of contaminants (drum not included except with the Model 6395
Systems). Connect the valve outlet to the compressed air inlet of the High Lift Reversible Drum Vac. The High Lift
Reversible Drum Vac pump assembly mounts into the small 3/4 NPT threaded hole of the drum (see diagram above).
Insert the white stand pipe suction tube into the 2 NPT threaded hole of the drum and secure by turning clockwise.
Attach threaded elbow adapter to the suction tube (clockwise). Slide the vacuum hose onto the quick-release elbow
fitting. Secure the quick-release elbow to the adapter (lever locks point upward when locked). Insert a tool that best
suits the application at the other end of the vacuum hose.
Connect compressed air line (not included) from the filter to the 1/4 NPT shutoff valve. Secure all vacuum connections
to prevent loss of suction.
Upon opening the shutoff valve, it is normal for the drum to make a “popping” sound as the High Lift Reversible Drum
Vac begins to fill or empty the drum.
The high powered vacuum can fill the drum in less than 2 minutes. An automatic safety shutoff valve prevents spills or
overfilling.
FLOOR SPILL APPLICATIONS
Systems using the Model 6901 Spill Recovery Kit will only pick up liquid only when the floor tool is pulled toward the
operator.
WARNING: Do Not Use With Any Material With A Low Flash Point Or With
Flammable Liquids Such As Fuel Oil, Alcohol, Mineral Spirits, Gasoline Or Kerosene.
TROUBLESHOOTING & MAINTENANCE
Clean air is essential for proper operation of the High Lift Reversible Drum Vac. A 10 micron or smaller filter
separator must be used on the compressed air supply in close proximity to the Reversible Drum Vac. If the filter
element becomes clogged with dirt, or a filter with a larger micron rating is us used and passes dirt into the pump, the
airflow becomes restricted and the pump can cease to operate.
For replacement or repair filter and regulator parts, contact EXAIR at 1-800-903-9247 or [e-mail].
Call [phone] for outside the US and Canada.
CLEANING
The safety shutoff valve that extends into the drum may require occasional cleaning. Immerse the Reversible Drum
Vac assembly in a mild cleaning or degreasing solvent. After cleaning, be sure the float moves freely. Use an air gun to
remove solution and contaminants.
If the Reversible Drum Vac becomes clogged, it can be disassembled for cleaning. Use a wrench to hold the hex body
firm while turning the cylindrical muffler assembly counterclockwise with a strapping wrench. Once the muffler
assembly is removed, use a pin-style spanner wrench to unscrew the threaded plug. Carefully remove the shim and
clean it, the O-ring and the pump body using a mild cleaning solvent. Pull the foam insert out of the muffler assembly,
being careful not to rip or tear it, and flush it out with a mild cleaning solvent. Be sure all components are dry before
reassembling. Note the orientation of the shim as shown in the illustration below and reinstall the threaded plug. Be
careful not to over tighten the threaded plug as this can distort the shim and restrict airflow.
Always clean the vacuum hose and attachments after every use.
If routine cleaning does not solve your performance problems,
