You should look at the following factors when choosing a dust extractor:
Most dust extractors available in today’s market have their capacity in the range of 8 to 14 gallons. However, you shouldn’t view the capacity of an extractor in isolation.
For, the capacity of a dust extractor has an impact not only on its portability but also on its ease of use. For instance, if your dust extractor has a large-sized tank, while it would require less frequent cleaning, it will be difficult to move. The reverse is true – more cleanings, more portability – for low-capacity dust extractors.
The power of a dust extractor is measured in cubic feet per minute – or CFM. It is the measure of air volume that the extractors pulls through its filter. On the smaller side, you can get ultraportable, cordless models offering 50 CFM. However, if you can afford to spend extra, there are models which can offer as much as 150 CFM.
The hose length of an extractors effects not only its agility but also its suction power. Greater the hose length, the more agile the extractor will be – which means you’d be able to clean a variety of surfaces in one go. However, the increase in hose length decreases the suction power of the device.
Variable Suction Speed
Rarely, if ever, we need to run the extractor at its highest speed setting. Therefore, what you need is an extractor which offers variable suction speed. So that you could be able to adjust its speed based on the task at hand.
Want your extractor to turn on alongside your woodworking unit? Then a tool-trigger system is a must-have. As its name implies, a ‘’tool-trigger’’ system turns on with your power tool to work in tandem. As a result, you won’t have to turn it on separately.
In addition to picking up fine dust particles, some dust extractors also offer to clean up liquid messes. You should go for this feature because no one knows what could happen in a workshop.
