Product Description
1. Product Description
Fume hoods are an integral part of most labs. These ventilated enclosures enable laboratory personnel to safely work with materials that produce hazardous fumes and volatile vapors. Selecting a fume hood that is the right fit for your laboratory is important and there are many different ducted and ductless designs to choose from. Traditionally, fume hoods consume large amounts of energy, but many newer units are designed with energy efficiency in mind, which reduces operating costs while providing the necessary protection.
6 Questions to Ask When Buying a Fume Hood:
- Which chemicals will you use within the hood?
- Is a ducted or ductless hood best suited to your needs and available space?
- Where will you place the fume hood in the lab? Consider workflows, access to external exhaust systems, and competing air patterns.
- What size fume hood will best suit your needs? Be sure to consider what (if any) equipment will be enclosed in the hood.
- Are any service fixtures or accessories such as airflow monitors, electrical outlets, water, or gas fixtures required?
- Are base cabinets for acid, solvent, or non-chemical storage required?

3. Type of Fume Hood
General Lab Use: Conventional hoods found on Purdue's campus and are approved for general chemistry, radioisotopes, and carcinogen or toxic chemical work.
High Performance: These fume hoods have containment-enhancing features allowing them to operate at lower face velocities while protecting the operator. Since less room air is exhausted, energy is conserved. REM will tag high performance hoods with a special standard operating procedure sticker, informing users of the appropriate air velocity range determined by the University.
Perchloric Acid: Special hoods equipped with a stainless steel or PVC duct and properly timed water wash down system. The wash down system must be used following each use of the acid hood. Using perchloric acid in a general lab fume hood may cause the acid vapors to settle onto the ductwork and create explosive perchlorate crystals. Serious injury or fatality may result to hood users or maintenance staff if the acid crystals are exposed to vibration and detonate.
Polypropylene (Acid Resistant): Dilute acids may be used at room temperature in most fume hoods, but if you are performing acid digestion, heating, or working with concentrated acids such as: HF, Aqua Regia, Nitric Acid, Piranha Solutions, etc., acid resistant hood and ductwork is required. Strong acids are corrosive to the duct work found in general lab fume hoods. Fume hoods constructed from polypropylene material are long-lasting and designed to resist harsh chemicals for years.
Walk-In: Equipped with a floor-mounted design, walk-in hoods specialize in exhausting chemicals that are used alongside large laboratory equipment. When using a walk-in hood, close the bottom sash to the floor and only raise the top sash to REM's designated working height. Do not obstruct the area at the face of the hood.
Ductless Filtered: Designed to remove potential hazardous fumes and vapors from the work area as the exhausted air passes through absorbent material, such as activated charcoal. Occasionally, the REM department is asked to approve purchases of ductless, filtered fume hoods for use in research labs. We do not recommend ductless fume hoods. We do not believe ductless fume hoods provide reliable protection against chemical exposure, and think they may, in fact, give workers a false sense of security.

5. FAQ
The process of researching and purchasing the right fume hood for your laboratory can seem overwhelming and choosing the right one is crucial to ensuring safety from dangerous chemicals and vapors in your lab.
Here are a few important questions and considerations to help you choose the right fume hood for your lab.
- What type of work are you conducting inside your fume hood
- Review your experiment methods and material lists.
- Document which chemicals, or solvents, you will be using and the concentration of each chemical
- Determine the evaporation rate of the chemicals.
- Chemical solvents evaporate at different rates and if not accounted for, can overwhelm the fume hood by evaporating at a rate too fast for the fume hood to ventilate
- What size lab hood do you need?
- Will you have equipment inside your laboratory fume hood?
- How large is the equipment?
- If your application involves extra-large equipment, such as drum containers, a walk-in fume hood might be appropriate.
- How many people will be working simultaneously under the fume hood?
- Depth - Consider buffer space.
- Perform your work at least 6 inches behind the sash to ensure a safety buffer zone is maintained.
- Height - Make sure your lab has ample height clearance for a larger bench top or floor mounted fume hood.
- How will fumes be filtered and exhausted?
- Duct or ductless
- A ducted fume hood connects to a remote blower of the facility HVAC system to safely remove noxious or dangerous chemicals from the work area.
- A ductless fume hood contains an integral blower, carbon filters to capture chemical vapors and, if required, HEPA/ULPA particle filters to allow recirculation of exhaust air.
- Which ventilation system should you use for a ducted fume hood?
- A ducted fume hood has two (2) options for ventilation control, constant air volume (CAV) and variable air volume (VAV).
- To choose between CAV and VAV, you will need to take into consideration both operating duration and budget.
- What are the Operating costs and install of a fume hood?
- Operating Costs:
- Ductless fume hood = the majority of operating costs for a ductless fume hood will come from filter charges.
- Ducted fume hood = The cost of operating a ducted fume hood can be calculated as a function of how much air the blower is exhausting. Thus, the operating cost increases as a function of volume of air (DFM) being moved.
- What accessories will you need for your fume hood?
- Fume hood accessories include base cabinets, light fixtures, airflow monitors, electrical outlets, cup sinks, and service fixtures for water, vacuum, or gas.
