Thank you for following our series on commonly asked question and answers about BaseVac Dental dry-vacuum systems. BaseVac has created this blog series to provide Dental Professionals the answers they require during the experiences of purchasing, installing and maintaining a BaseVac Dental dry-vacuum system.
Thus far, we have covered;
- Common questions before upgrading to a BaseVac dry-vacuum
- Common questions during the BaseVac installation
- Common questions after a few months of service
- Common questions after 2-3 years of service
Today we will be beginning the last segment of our Commonly Ask Questions about BaseVac, which is commonly asked questions after the first five years.
The motor runs but I get no suction
· This is normally a sign that the vacuum pump vanes have worn to the point they have broken. The vanes have an 8,000-hour normal life span.
· New vanes properly installed will correct the problem.
· The inline inlet check valve may have rusted closed, restricting the air flow.
The suction is much noisier than before
· This is normal after four or five years of operation. It is a signal that the vanes have worn and should be replaced. The vanes have a normal 8,000-hour life expectancy. Scheduling a change of vanes will prevent unexpected failure of your vacuum pump.
· The blow off exhaust valve may have stuck partially closed, restricting the air flow. A simple replacement of the inexpensive valve can help the system function more efficiently.
