💨 Few Factors You Have to Know Before Buying a Fume Hood
Fume hoods are the common and reliable engineering control deployed for safe labs. But selecting a fume hood can be a confusing task. Fume hoods come in various configurations and sizes, complicating the choice.
First, spend a few minutes to know the answers to the questions below — this will help you select the right fume hood and place the right enquiry with our specialists.
❓ Seven Key Questions Before You Order
-
1
What is the purpose of a fume hood? Define the type of chemicals, reactions, and processes the fume hood will be used for — this determines the required filtration, material, and exhaust type.
-
2
What size of fume hood do you need? Available in widths of 900mm, 1200mm, 1500mm, and 1800mm with depth options of 750mm and 900mm. Size depends on the equipment and procedures to be carried out inside.
-
3
What are fume hoods made of? Fume hoods are typically made of chemical-resistant materials — the interior lining, worktop, and frame materials vary based on the chemicals handled. Options include epoxy resin, phenolic resin, stainless steel, and polypropylene.
-
4
What are the required accessories outside of the fume hood? Accessories include blowers, ducts, canopy, internal lighting, electrical sockets, water taps, cup sinks, and safety features like airflow monitors and alarms.
-
5
How will the fume hood be exhausted? Determine whether the exhaust will be ducted directly to the outside atmosphere, or if a ductless/recirculating model with filtration is required. External ducting provides higher performance for volatile chemicals.
-
6
Do you need a built-in blower or a remotely located blower? Built-in blowers are simpler to install but generate heat inside the lab. Remote blowers are located on the roof or outside the building, reducing noise and heat inside the laboratory.
-
7
What is the plan — layout of the duct run? The duct run layout determines the length of ducting required, number of bends, and the static pressure that the blower must overcome. A well-planned duct layout improves energy efficiency and performance.
