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

You can post a sticker near the hood to remind users to close the sash when not in use. This also educates new users that a lower sash is safer.

What are the limitations of ductless filtering fume enclosures?

They are limited to certain chemicals based on the manufacturer's guide. Filters have a finite adsorption capacity and must be monitored for saturation and replaced periodically (annually or every 600 hours).

What are the key advantages of ductless fume hoods over ducted ones?

They require no costly ducting or venting, avoid permitting issues, are adaptable for layout changes, are environmentally friendly, and offer significant energy cost savings.

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 back into the lab.

Q:How does a fume hood work?

It uses a sash to contain vapors and blowers to draw air through filters. To work safely, keep work at least six inches from the sash, keep the sash closed when not in use, and ensure baffles are free of obstructions.

Q:Why do fume hoods use so much energy?

Energy is consumed by the air being sucked through the hood. Labs use 100% outside air that must be heated or cooled, and large fans are required to move this air through the building and the hood.

Q:How does shutting the sash save energy?

Most hoods are variable air volume (VAV). Lowering the sash reduces the building's fan speed and the volume of air moved, thereby saving energy.

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. It acts as a safety barrier while still allowing some airflow to remove fumes.
