Process
Effective against chemical vapors generated during processes including reflux, distillation, flash chromatography, evaporation, etc.
Containment
Unique design includes a bypass system using air entrapped by the hood to actively engage, contain, and exhaust fumes from the containment area.
Design
Similar overall design structure used in standard sizes to simplify lab planning, layout, and HVAC coordination.
Fume Hood Series
Overlapping Sash Bypass (OSB)
The overlapping sash bypass provides better containment and never needs to be removed or replaced if Variable Air Volume conservation systems are retrofitted into an existing SAF T Flow installation. In all exhaust applications, bypass air does productive work clearing fumes from behind the sash and means all exhausted air does containment work at all times.
We have tested our OSB from 100 FPM full open sash down to 60 FPM at 18″ sash opening with ASHRAE 110 containment equipment and cannot tell any difference in containment performance at any selected face velocity or opening with this range. Breathing zone containment from 0.005ppm down to undetectable.
Slide-out Top System
The slide-out feature allows complete top replacement without lifting the fume hood superstructure and disconnecting plumbing or ductwork.
STABILIZING BAFFLE CONTROL SYSTEM
Slots oriented in both X and Y axis promote even airflow back into the hood interior, from the top to the bottom of the sash opening. The rear baffle is removable for easy cleaning.
QUICK-SET SCAFFOLDING SYSTEM
Detachment knobs make for quick scaffolding setup and easy rear baffle removal for cleaning.
CLEAR CORD FLIP-UP AIRFOIL
Used for safe cord routing and air flow direction.
Steel SUPERSTRUCTURE AND CHAIN DRIVE
14 – 18 gauge framing system and #35 steel chain drive will run 50,000 cycles without breaking.
