How do I remind myself and my roommates to close the sash?

You can post a sticker near the hood to remind users to close the sash when not in use, educating them that a lower sash is safer and should only be open during experiments.

What are the limitations of ductless fume hoods?

They are not suitable for high evaporation, viruses, bacteria, trace metals, perchloric acid, acid digestions, or radioisotopes due to specific filter affinities and potential chemical reactions.

What is the average lead time for this product?

The lead time is one month during peak season and within 15 workdays during the off-season.

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, filtering them, and either exhausting them outside or recirculating clean 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 ensure the sash remains closed as much as possible.

Q:Why do fume hoods use so much energy?

Energy is consumed by the air being sucked through the system. Labs use 100% outside air that must be heated or cooled, plus electricity to run large fans to move the air.

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 actively setting up or modifying an experiment, as it acts as a critical safety barrier while maintaining some airflow.
