Product Q&A

Q:What is a fume hood?

A fume hood is laboratory equipment designed to minimize exposure to hazardous chemicals by drawing away harmful vapors and filtering them before exhausting or recirculating the air.

Q:How does a fume hood work?

It uses a sash to contain vapors and blowers to draw air through filters. For safety, keep work at least six inches from the sash plane and keep the sash closed as much as possible.

Q:Why do fume hoods use so much energy?

Energy is consumed by moving large volumes of air through the building and conditioning 100% outside air for lab comfort, rather than by the hood unit itself.

Q:How does shutting the sash save energy?

Variable air volume (VAV) hoods reduce fan speed and air volume when the sash is lowered, as the sash position is connected to the building's ventilation system.

Q:Is it safe to shut the sash?

Yes, shutting the sash is the safest option when not setting up experiments, as it acts as a safety barrier while maintaining airflow to remove fumes.
