Frequently Asked Questions
How do I install the dome top cleanstream filter?

Warning: DO NOT vacuum oily or hazardous materials such as asbestos, lead, pesticides or other health endangering materials. DO NOT vacuum burning objects, embers or warm fireplace debris. Warning: Remove plug from outlet before removing the tank cover.

How often should I clean the filter?

This can vary widely depending on how often your dust collector is used, and what kind of dusts it's exposed to. You should typically clean it only once you've noticed a considerable drop in suction performance. In our experience this can be around 1x per year, but with heavy amounts of sanding it could be as often as 1x per month. A pressure meter such as our Filter Efficiency Gauge can also be used to monitor pressure buildup.
