When is it time to replace your fume hood? 

When your hood sash wears out

The sash is a movable panel that covers the opening of the fume hood. Sashes are usually the first component to fail as there is constant tension on its cables and sash glides. If the sash cannot be repaired or replaced, it may be necessary to consider purchasing a new fume hood to ensure the safety and effectiveness of your laboratory’s ventilation system.

When it fails a safety check

Regular safety checks are crucial to maintaining an effective fume hood and a safe lab environment. If your fume hood does not pass its annual filtration efficiency test, you should replace it with a new hood.

When your fume hood begins to degrade

If your fume hood begins to degrade, it is a good time to replace it with a new one.

Signs of degradation include:

  • Discoloration of materials
  • Fogging on the sash
  • Loud noises from the internal fan 
  • Corrosion 
  • Rust
  • Permanent stains
  • Warping

While these issues do not all necessarily require immediate replacement, they serve as indicators that your fume hood is no longer functioning at an optimal level and may not be filtering air effectively. If immediate fume hood replacement is not necessary, it may be in the near future.

When your lab size changes

If your lab is growing, it may be time to update your fume hood. Fume hoods will be used more as your lab grows, causing more wear and tear and potentially putting employees’ health at risk. If your lab is expanding, it might be time to update your fume hood to a newer, more efficient model.

How to select a new fume hood

When selecting a new fume hood, consider factors like size, material, and ventilation requirements to ensure you are choosing the optimal hood for your unique lab applications. Also, be sure to follow all manufacturer guidelines and recommendations for installation and ongoing maintenance.
