Maintenance for Dental Vacuums: Dry and Wet

To keep your dental vacuum in good working order, there are some regular maintenance tasks that need to be done. These tasks will vary slightly, depending on whether you use a wet vacuum or a dry vacuum in your practice. Doing the maintenance will extend the overall life of your vacuum, so it is well worth the time investment.

Wet vacuums require water to create a vacuum in the lines. Though reliable, these systems require a lot of water to operate. Because of the need for water, sediment and minerals from the water supply can wear the pump and cause damage – hence the need for regular maintenance. Dry vacuums require no water. They have little maintenance, but still need to be maintained to extend the overall lifespan.

Daily Maintenance Tasks for All Vacs

Flush the vacuum lines every day. Make sure this includes all lines and tubing in your system. You should use a non-foaming Evacuation System Cleaner 2 to 3 times a week to ensure you get the best possible results. Check solids collectors and clean daily and change as needed. When cleaning solids collectors, keep in mind there may be biologically hazardous material in the collector. Use gloves & face mask while cleaning the unit to protect yourself.

Weekly Maintenance Tasks for Wet Vacs Only

Inspect the main intake filter. Clean the filter and screen, or replace as needed. If you do not have replacements on hand, contact the service department to order more.

Monthly Maintenance Tasks

For Wet Vacs Only

Change the main intake filter. Check and change the water filter. If the filter is not changed regularly, sediment from the water supply can work its way into the various parts of the vacuum and cause permanent unit failure, leading to an expensive replacement.

Wet and Dry Vacs

Clean the vacuum motors to prevent buildup of dust and debris. Dust and debris can block the flow of air from the cooling fan and create issues with heat and performance.

Quarterly Maintenance Tasks for Dry Vacs Only

Check the vacuum relief valve filter. If your dry vacuum system uses oil lubricant, check the oil levels. If your system requires an oil change, contact the manufacturer or review your owner’s manual to determine how to proceed. Some systems are closed and sealed, but will still need to have their oil checked regularly. If lubricant is low, contact the service department for your unit. Newer dry vacuum systems are oil free, therefore you only need to check the inline micron filter periodically and change it every 3-6 months, contact dealer for replacement filters.


Schedule an appointment with the service department for your vacuum. They will check and replace all lines, filters, belts, oil, etc. as needed, depending on the model you use. Remember, this system is the “heart” of your business.

If you have any questions or concerns about the maintenance on your vacuum system, contact the service department or manufacturer right away. Review the owner’s manual to ensure you are performing all necessary tasks as required, and using the appropriate cleansing products to keep the lines and motor clean. Using the wrong cleaning products can create issues with vacuum operation, and may lead to the need for repair or replacement.
