Lab research and analysis benefit significantly from specialized equipment that keeps potentially hazardous materials away from the technician or student. Laboratory fume hood and exhaust systems allow research to be performed safely on materials emitting toxic, flammable, or corrosive vapors, gasses, and dust.

Ravensberg is pleased to provide fume hood and exhaust systems for laboratory settings needing such equipment. As a dealer for Air Master Systems, we work to provide quality products that allow research without putting individuals at risk of dangerous exposure.

What Are Fume Hood and Exhaust Systems?

A chemical fume hood is an enclosed workspace where a researcher or student may work with hazardous materials and not be openly exposed.

Paired with a ducted or ductless exhaust system, it allows the safe handling of dangerous materials without exposing the technician to harm as they work. A ducted hood filters the laboratory air and funnels it outside to prevent contamination. In contrast, a ductless hood system utilizes a certified filter to return clean air to the space.

Before scientists and researchers had safe environments to test and evaluate substances, they would use an open lab that could expose themselves and others in the area to dangerous materials. Today, technology has evolved to allow for controlled research and experimentation within a fume hood.

How Does a Fume Hood Work?

Laboratory fume hoods are paired with an exhaust system to remove the potential fumes from their housed environment while allowing the technician safe access to substances. In addition, some systems do not require exhausting vapors into the outside environment. 

They instead use an in-house filtering system, eliminating the need for added ductwork and fan housings. Whatever your requirements, we will provide the best lab hood for your space.

Things to Consider When Purchasing a Fume Hood

We specialize in designing and installing the perfect fume hood and exhaust system for your laboratory needs. Our experienced technicians will help you find the right size, filtration type, and fume hood style to meet your lab environment’s specifications.

When purchasing a fume hood, there are notable items to consider:

  • Size: The fume hood is the “heart” of any lab, so its size and capacity are vital. It must fit within your laboratory’s space requirements but must also be large enough to accommodate everything necessary for a successful workflow.
  • Ventilation System: Consider whether you need an exhaust system that vents outside the building or an in-house filtering system.
  • Type: Knowing the kind of substances you’ll be working with helps determine the best fume hood for your needs. It could range from a standard chemical hood to one with unique features like UV protection.
  • Material: Selecting the right materials for your fume hood is critical to ensure its long-term durability and safety. Options include steel, aluminum, polypropylene, and more.
  • Safety Standards: The fume hood must meet the safety standards and regulations set forth by your local health department to protect you and your team.

Fume Hood FAQ

Choosing the right fume hood and exhaust system for laboratory activities can be daunting. We’ve gathered a list of frequently asked questions to aid you in your decision.

When are fume hoods necessary?

Fume hoods are necessary for any activity that may cause hazardous materials to be released into the air. Whether a laboratory experiment or commercial production, a fume hood will protect everyone from toxic exposure.

What kind of filter does a fumehood use?

The type of filter used depends on the type of fume hood you have. Ducted fume hoods use an external fan and ductwork to remove vapors from the lab. In contrast, a ductless enclosure uses an integrated filter to clean the air before returning it back to the laboratory space.

How should you organize a work area within your fume hood?

Organize your work area to ensure the safety of everyone in the lab. It’s essential to have clear pathways and avoid overcrowding the hood.

When would I need a high-performance hood?

High-performance hoods work best when the quantity or concentration of hazardous materials is higher than usual. These hoods use a low air volume to maintain the necessary protection while reducing energy costs associated with regular fume hoods.

What safety considerations should I follow when using a fume hood?

Always wear appropriate personal protective equipment (PPE). Additionally, regularly inspect and test your fume hood to ensure it works properly.

How often should I maintain my fume hood?

Ensure a professional inspects and tests your fume hood annually. Moving parts or filters should be cleaned regularly to prevent clogs and maintain the system’s integrity. Ravensberg provides expert fume hood inspections and repairs should your system require it.

What type of materials can I use for a custom fume hood?

When designing a custom fume hood, you can choose from many materials. Options include painted steel, stainless steel, polypropylene for the inner walls, and painted or stainless steel for the outer shell. Additionally, you can create viewing panels with glass.
