Machine Compatibility

This style of filter is used on select Prochem, Kärcher and Sapphire Scientific truckmount systems. Applications may include certain versions of:

• Prochem Apex truckmounts
• Prochem Everest truckmounts
• Prochem Blazer truckmounts
• Prochem PTO truckmount systems
• Select Sapphire Scientific truckmounts
• Other machines originally equipped with filter 20-071 or 86193540

Why This Filter Is Important

The recovery tank collects dirty water along with lint, hair, carpet fibers and other debris. The blower inlet filter forms an important barrier between that debris and the vacuum blower. Operating with a missing, damaged or severely clogged filter may reduce airflow and can allow contamination to reach more expensive truckmount components.

Possible Signs of a Clogged or Damaged Filter

• Reduced vacuum or water-recovery performance
• Slower drying times
• Restricted airflow
• Vacuum blower operating at a higher temperature
• Vacuum-relief system activating more frequently
• Torn, crushed or separated filter media
• A warped frame that no longer fits or seals correctly

Cleaning and Maintenance

1. Turn off the truckmount and allow the system to stop completely.
2. Remove the filter from the waste or recovery tank.
3. Remove loose lint and debris from the filter surface.
4. Rinse the filter with clean water as needed.
5. Allow the filter to drain before reinstalling it.
6. Replace the filter if the media, frame or seal is damaged.

Inspect the filter regularly and clean it before airflow becomes restricted. Cleaning frequency will depend on the type of carpet, debris level and amount of daily use.

Ordering Assistance

To confirm compatibility, email your machine’s complete model number, serial number and a photograph of the original filter before placing the order. Serial-number verification is recommended because truckmount manufacturers may change components during a model’s production run.
