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.
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.
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.
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.
