About

Contained Vented Enclosures (CVEs) – Laminar Flow Hoods

Single HEPA Filter – Bag Out Series

Flow Sciences’ Single HEPA Series Contained Vented Enclosures are designed for maximum containment with the use of airfoils and plenums, creating a laminar airflow across the work surface, which reduces eddies and turbulence. The ETA Series features a front door lift that allows for easy loading and unloading of equipment. The single 4” thick HEPA filter and fan is ideal for benchtop / scale up and nanotechnology applications, and has been proven by an independent test organization to contain loss to below 1 µg/m^3 based on process and quality. The top-mounted exhaust system can recirculate air into the lab or send it directly to the house exhaust without transferring vibration from the fan unit to the work surface. As an additional safety measure, FSI’s Contained Vented Enclosures feature a face velocity alarm that visually and audibly alerts the operator when airflow is compromised. These features allow for reproducibility and accuracy of weighing. In case of an accident, the dished phenolic base is chemically resistant and designed to contain spills.  The ETA Series is available in 3’ or 4’ standard width units and features options such as LED lights and waste ports to safely transfer contaminants from the enclosure.

Dual HEPA Filters – Bag In / Bag Out Series

Flow Sciences’ Dual HEPA BIBO Series of Contained Vented Enclosures are designed to prevent loss of containment with the use of airfoils and plenums, creating a laminar airflow across the work surface, which reduces eddies and turbulence. The ETA Series features a front door lift that allows for easy loading and unloading of equipment. The single 4” thick HEPA filter with fan is ideal for benchtop / scale up and nanotechnology applications, and has been proven by an independent test organization to contain loss to below 1 µg/m^3 based on process and quality. FSI’s state-of-the-art BIBO feature allows the operator to safely remove and replace the main filter while maintaining maximum containment from toxic fumes and particles. The top-mounted exhaust system can recirculate air into the lab or send it directly to the house exhaust without transferring vibration from the fan unit to the work surface.

OVERLAPPING SASH BYPASS PROVIDES BETTER CONTAINMENT AND DOES NOT REQUIRE CHANGES IF VAV IS INSTALLED IN THE LAB FUME HOOD
 

SAVE OVER 60% OF ENERGY WITH THE SAF T FLOW FUME HOOD SERIES OVER OTHER LAB FUME HOODS

GREAT ANSI/ASHRAE 110 CONTAINMENT RESULTS UNDER A WIDE RANGE OF CONTSTANT VOLUME AND VAV CONDITIONS IN THE LOW FLOW SAF T FLOW CHEMICAL FUME HOOD SERIES

DESIGN. Uniquely designed for safety and convenience, the SAF T FLOW™ features include a different kind of bypass system that assures all airflow entrained by the hood is actively used to engage, contain, and exhaust fumes from the containment area. High efficiency allows a high degree of energy saving which saves lots of money.

SAFETY. The SAF T FLOW™ lab fume hood series provides safety from chemical vapors generated during chemical processes including reflux, distillation, flash chromatography, evaporation, and other process equipment applications.
 
FLEXIBILITY. SAF T FLOW™ chemical hood uses the same overall design structure in all standard fume hood sizes to maximize simplicity in lab planning, layout, and HVAC coordination. This approach allows any popular low flow exhaust option without requiring expensive retrofits to the hood.

SLIDE-OUT TOP SYSTEM.  Sometimes tops shatter. The slide-out feauture allows complete top replacement without lifting the fume hood superstructure and disconnecting plumbing and ductwork.

STABILIZING BAFFLE CONTROL SYSTEM.  Slots orented in both X and Y axis promote even air flow back into the hood interior from top to bottom of the sash opening. The rear baffle is also removable for easy fume hood cleaning.
 
QUICK-SET SCAFFOLDING SYSTEM.  Detachment knobs make for quick scaffolding setup and easy rear baffle removal for cleaning of the fume hood.
 
CLEAR CORD FLIP-UP AIRFOIL.  Used for safe cord routing and airflow direction in the chemical fume hood.
 
HEAVY GUAGE SUPERSTRUCTURE AND CHAIN DRIVE.  14 and 18 guage framing system and #35 steel chain drive will run 500,000 cycles without breaking.

OVERLAPPING SASH BYPASS

OVERLAPPING SASH BYPASS

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, with any exhaust strategy.
 
 
Keep in mind, volumetric reductions in fume hood exhaust can save thousands of energy dollars each year on each hood. This is the main reason traditional constant volume hoods have been frequently converted to VAV to save exhaust air and energy.
 
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 within this range. Breathing zone containment ranged from 0.005ppm down to undetectable. Fantastic containment at very low exhaust volumes! 

Sustainability


When Considering Sustainability,
Which Fume Hood is Really the Best Deal?


In the present cost-conscious economy, there is substantial pressure on building contractors to buy the least expensive exhaust hood and focus on sustainability. What is saved on such inexpensive hoods at the outset is often sacrificed over time in higher maintenance and energy costs. The true cost of a fume hood is made up of the following:

1) The Original Cost to Purchase & Install

2) The Yearly Maintenance Cost

3) The Yearly Energy Expense

Since building contractors typically only focus on hood costs; maintenance and energy costs have become the problem of someone else. Fume hood cost of ownership should include an analysis of all three costs to reach a sensible overall purchase and construction plan for the lab owner. If cost, maintenance, and energy consumption are all minimized, the final hood choice will also be the most sustainable.


COST

OF

OWNERSHIP

Here’s why all three costs are relevant. FSI and Wave Consulting evaluated the SAF T FLOW™ fume hood and ten competitors for purchase price, maintenance cost, and energy consumption. The initial purchase price of the FSI unit was more expensive, but by comparing the energy usage and maintenance costs of the SAF T FLOW™ unit versus Brand G and Brand I, we can clearly see that after 15 years (an often-used construction cycle time for labs and leased equipment), the FSI hood is the most cost efficient option.



Exhausting Conditioned Air and
Maintenance Costs are Very Expensive.

Obviously, any lab owner should recognize that the initial costs of containment systems are not the only price that should be taken into account during the hood selection process. The technology used in the SAF T FLOW™ Fume Hood series requires less CFM and still maintains excellent containment. This results in significant yearly savings, and drastic savings over a 15 year lab cycle time. The SAF T FLOW™ Fume Hood performs better and more efficiently and includes advanced design features which cost more on the front end. This extra initial cost is rapidly recovered; usually in the second year of service.



When you puchase a SAF T FLOW™ Fume Hood, you will see the break even point in 1.8 years compared to legacy hoods that require more energy and require more maintanance. Total cost of ownership is the only way to evaluate any purchasing decision. Many companies are considering the equipment purchase based on cost of ownership, and you should too.



Learn more about the sustainability of the SAF T FLOW™ Fume Hood series by contacting an FSI containment expert and asking for the SAF T FLOW™ Cost of Ownership white paper. There you will see these statistics and more!

Exhaust Option B

FAN / BIBO

The bag in / bag out (BIBO) filter cahnge method is unique to FSI and we are very proud to provide double HEPA filtration and ease of filter change. This system allows for circulation into the lab and also connection straight to house exhaust. The BIBO system allows for the filter to be changed in a clean environment where the saturated filter is not exposed to the lab environment.

Exhaust Option C

NO FAN / WITH FILTER

This enclosure is designed for applications that need to be filtered but still go to house exhaust. Featuring a 4″ HEPA filter and exhaust cap, a 6″ exhaust port should be attached to existing house exhaust. This is enclosure can also be used for explosion proof (XP) applications.


Exhaust Option D

NO FAN / NO FILTER

This exhaust option is the most similar to the original VBSE™ from Flow Sciences. With no fan and no filter, this enclosure is versitile and can be used to connect directly to house exhaust or to a remote fan/filter. Labs with upper cabinets could benefit from this enclosure as the total height is lesser than any other exhaust option.


Exhaust Option E

NO FAN / BIBO

This exhaust option is engineered for applications that need dual HEPA filtration and also sent directly to house exhaust. The Bag in / Bag out (BIBO) filter change procedure includes two 4″ HEPA filters with a simple primary filter changeout method that never exposes the lab to the saturated filter. This enclosure is also used for explosion proof (XP) applications.


Exhaust Option F

MESH FAN / FILTER


Exhaust Option G

MESH FAN / BIBO


Exhaust Option H

MESH FAN / INVERTED
