What kind of fans are used?

  • We use 3 different types of fans depending on the model. We use Axial, Centrifugal and Dayton blowers. Each unit has more information listed in the photos (e.g. wattage, voltage, weight, etc.).


What size hoods do you offer?

  • Please visit our shop page to see our current models. If you would like a custom flow hood, please contact us so that we can get you a quote.


How can I tell if my flow hood is blowing enough air?

  • Hold a lighter in front of the flow hood, roughly 3-6 inches away from the face of the filter. The flame should have a 30-90 degree bend.

  • You can also run regular open air petri dish tests in front of the unit to ensure you are working with the cleanest filter possible.


Do you ship to other countries?

  • Yes, we do! Please research your voltage requirements. Our units are 110-120v and will require a voltage converter if being used outside of the U.S. We offer voltage converters in our shop. We will not be liable for any damages if you choose not to purchase a converter direct. Please message us if you have any questions.

  • *Please note that voltage ADAPTERS will NOT work*


How much is a custom engraving?

  • We are not currently offering custom engravings.


How long do the filters and fans last?

  • The filters are rated for up to 3,000 hours. 

  • The fans are rated for 30,000 hours.

  • All fans are covered for 1 year from the date of purchase.


What maintenance does my flow hood need?

  • We recommend replacing the filters about every 6 months to one year depending on frequency of use. Routine cleanings will optimize results and prolong the longevity of your filter.

  • We recommend getting inside of the unit and cleaning it every few months. This can be achieved by using a vacuum to suck out any debris that may have accumulated inside.
