SAF T FLOW™ Fume Hood
Superior Engineering, Assembly & Performance
Our SAF T FLOWTM fume hood series contains processes that create fumes, particulate, and dust. Secondarily, these fume hoods protect users from application hazards such as fires, chemical spills, and adverse reactions. Their durable construction ensures containment under a wide range of applications. It’s modular construction enables easy access to valve configurations and plumbing for easy modifications.
Process
Processes include research chemistry, chemical synthesis, acid etching, petroleum synthesis or analysis, mineral diagnostic, and many more.
Containment
Conforms with ASHRAE–110 standards. Additional testing shows excellent vapor and powder containment during processes following ISPE guidelines.
Equipment
Accommodates glassware, heating mantels, weighing devices, packaging equipment, pressure bombs, distillation columns, ovens, pumps, RF heaters, etc.
Benefits
Applications & Materials
The SAF T FLOW™ fume hood series is expertly crafted to handle APIs and various toxic powders. Built from heavy-gauge steel, the fume hood is robust enough to support its entire weight, ensuring safety in diverse applications.
Design & Durability
Boasting a glass sash and sash bypass, with outer panels made of powder-coated stainless steel, the design ensures longevity. A chain drive, complemented by a counterweight system, guarantees at least 50,000 easy-lift sash cycles.
Airflow & Containment
The Overlapping Sash Bypass (OSB) employs bypass air to efficiently clear fumes. Tests from 100 FPM to 60 FPM have confirmed consistent containment performance, regardless of sash position, ensuring safety and effectiveness.
Interior & Maintenance
The interior is accentuated by a stabilizing baffle, which promotes even airflow. This baffle, having slots on both X and Y axes, is removable, facilitating easier cleaning and maintenance.
Base & Safety
The standard phenolic resin base, with its channeled edges, effectively contains spills. This base not only offers chemical resistance but also ease of replacement, enhancing the hood’s overall safety features.
Standard Sizes
This series caters to varied width requirements, available in standard widths ranging from 3′-10′. Custom dimensions are available based on need.

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 500,000 cycles without breaking.
