When it comes to safety, it always pays to know more. Fume hoods come in a number of airflow types. Each has its own strengths and weaknesses. Knowledge of airflow types plays a vital role in deciding which fume hood is best suited to your needs.

Auto Bypass: (Used in Maxima range)
Auto bypass systems ensure that a constant airflow is maintained through the fume hood. This is done by means of a bypass valve that lets in more air as the sash is closed. The bypass system ensures that the HVAC system does not have an unnecessary load on them. This system is cheaper in terms of initial cost, but in case of AC labs, the large volume of air lost increases operating costs.


High performance hoods (Technology used in Inventa Range):
LabGuard’s own research has led to the development of this system. Our research team has incorporated a number of aerodynamic enhancements into the fume hood. The system requires significantly less airflow than conventional auto bypass hoods, while giving you total safety. This leads to great savings in airflow and is economical in the long run.


Variable Air volume (Available with Inventa Range):
One of the latest advances in fume hood technology: variable air volume (VAV) fume hoods change the blower fan speeds as the sash is closed. In case of AC labs this system leads to great savings in the long run, reducing the amount of air lost. Click here to view the demo for Airflow types

Auto Sash system

Reduce operating costs while working conveniently.

The AutoSash system is an intelligent system that detects operator presence. It sets the sash at a safe working height when it detects an operator and closes the sash if it detects no operator present for over 2 minutes.

The automatically closed sash ensures that the minimum amount of Air Conditioned air is wasted from the lab and gives you the maximum benefit of the VAV airflow system.
