Frequently Asked Questions
Can I vent my system outside?

If you have conditioned air in your shop, (Heat or cool) then exhausting outside can be costly. If your building is small and well-sealed, you can interfere with flue exhausts as well. Close neighbors might object. If the Dust Collection system is run intermittently it is generally not a problem. Most buildings have enough leaks and crevices where the aforementioned volume of air does not cause problems. If you have a problem opening or closing an outside door when the DC is running, crack a window slightly. The rule of thumb is for every 500 CFM have at least 1 sq/ft of return air coming back into the shop. A lot of our customers blow exhaust air outside successfully.

Can I use this steel cyclone with smoldering or abrasive debris?

Yes, absolutely. This cyclone is built with heavy-gauge, powder coated steel for industrial applications collecting highly abrasive or smoldering materials e.g. hot ash/soot, blasting powders, concrete, grinding dust, etc. Please note that you should also ensure that your vacuum/dust collector is rated to accept these same types of materials i.e. do not collect hot/smoldering materials if your vacuum isn't normally capable of collecting this type of waste.

Is the steel cyclone rust-proof?

In short, no. The steel cyclone has a powder-coat finish, ensuring that it's durable and rust resistant, but if you expect to have your cyclone exposed to water on a regular basis (e.g. exposed to harsh weather, submerged in water, etc.) we recommend you find additional covering to prevent corrosion over time.
