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 Reversible Drum Vac by causing
excessive line pressure drop.
COMPRESSED AIR SUPPLY
The Reversible Drum Vac uses normal shop air supplies of 80 to 100 PSIG (5.5 to 6.9 BAR). 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.
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 9005 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 Reversible Drum Vac, within 10 to 15' (3 to 4.6m) is best.
USING THE REVERSIBLE DRUM VAC
Use a drum that is in good condition and is free of contaminants (drum not included except with the Model 6196-5,
6296-5 and 6396 System). Connect the valve outlet to the compressed air inlet of the Reversible Drum Vac. For the
Model 6196-5 and 6296-5 Mini Reversible Drum Vac System, place the drum lid on the 5 gallon drum and secure in
place with locking ring. The 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.

USING THE REVERSIBLE DRUM VAC (Cont.)
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 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
The Model 6191 Reversible Drum Vac includes a floor tool for spill pick-up. The Floor Tool Picks Up Liquid Only
When It Is Pushed Away From The Operator. Systems using the Model 6091 Spill Recovery Kit work when 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 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].

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. 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,
