Supreme Air Venturi Fume Hoods Features
Electromechanical
Sash Stop
The Venturi is equipped with a sash stop located within the sidewall of the fume
hood. A raised sash will meet the sash stop at a preset height and will stop upon
its encounter. To defeat the sash stop, press the “Sash Release” button. The sash
stop will release for 1½ seconds so the sash can be raised to full open. The sash
stop will not impede sash movement when the sash is being closed.
In the event of a power failure the sash stop may be released manually. To
manually override the sash stop, remove the protective plug button located just
behind the sash track, midway up, in the left end interior liner. Using your finger or
a probe, find the sash stop mechanism, and slide the plunger to the rear.
Belt Drive Pulley System
Venturi employs a low maintenance, dual shaft, belt and gear driven sash system.
It is recommended that a user check the hood roof mounted sash support system
annually to ensure no foreign objects or obstructions have found their way into
the belt and gear path. A user should annually lubricate the pulley shaft bearings
with white lithium grease. The belt and gear has been tested to 300,000 cycles.
Dynamic Barrier Bypass
The Venturi fume hood Upper Bypass is factory set and should not be modified.
In the event of a significant change in airflow application please contact
Kewaunee to see if the Upper Bypass requires modification.
Airfoil
The Lower Airfoil should not be removed or altered to ensure safe fume hood
operation. Airfoils should be cleaned of all exposed chemicals in accordance to
the MSDS sheets and your laboratories safety guidelines.
