Fume hoods, also known as fume cabinets, are an essential component of any laboratory that handles volatile chemicals, biological agents, or potentially hazardous substances. Their primary function is to provide a safe environment by capturing and containing hazardous fumes, vapors, gases, and particles, preventing exposure to laboratory personnel. For over a century, Kewaunee has been a trusted name in laboratory design and equipment, offering cutting-edge fume hoods that ensure safety, reliability, and efficiency in laboratory environments.
Whether you’re working in a research facility, pharmaceutical lab, or industrial setting, Kewaunee’s fume hoods are designed to meet the highest standards of safety and performance, protecting both the user and the environment from hazardous materials.
What Is a Fume Hood?
A fume hood is a ventilated enclosure that captures and exhausts harmful fumes, vapors, and particulate matter produced during chemical processes, biological experiments, or laboratory testing. Fume hoods are designed to protect laboratory personnel by drawing toxic gases or airborne contaminants into the hood and away from the operator, preventing exposure to harmful chemicals.
The basic structure of a fume hood includes a sash (movable glass or acrylic barrier), which allows the operator to control airflow and adjust the work area’s exposure. The hood operates by creating a negative pressure environment that draws air into the work area, where the contaminants are filtered or exhausted outside the building.
Fume hoods come in various types and configurations to suit specific laboratory needs, including constant air volume (CAV), variable air volume (VAV), and walk-in fume hoods. Each design offers specific benefits for various laboratory settings, ensuring that safety is always prioritized.
Why Fume Hoods Are Essential in Laboratories
Fume hoods serve a critical role in ensuring the safety and efficiency of laboratory work. Here are the primary reasons why fume hoods are indispensable in research, industrial, and healthcare laboratories:
-
Protection from Toxic Exposure Fume hoods are designed to capture and contain hazardous fumes, gases, and particulate matter, preventing them from escaping into the laboratory environment. This protects researchers and technicians from inhaling toxic substances, which could lead to acute or chronic health issues.
-
Preventing Contamination Fume hoods also help prevent cross-contamination in the laboratory. By containing volatile chemicals or biological agents, they ensure that experiments and samples remain uncontaminated by external airborne agents. This is especially critical when working with sensitive materials, such as pathogens or highly reactive chemicals.
-
Compliance with Safety Regulations Laboratory safety is heavily regulated, and fume hoods are integral to meeting standards set by organizations like OSHA (Occupational Safety and Health Administration) and ANSI (American National Standards Institute). Using fume hoods ensures that laboratories comply with health and safety regulations designed to protect personnel from exposure to hazardous chemicals.
-
Improved Laboratory Efficiency With the assurance that harmful substances are contained, laboratory workers can focus on their tasks without worry. Fume hoods create a safe working environment that allows researchers to conduct experiments, prepare chemical mixtures, and handle volatile materials with peace of mind, which ultimately improves productivity.
Why Choose Kewaunee Fume Hoods?
Kewaunee is a recognized leader in laboratory equipment and design, offering fume hoods that are engineered for maximum safety, reliability, and performance. Here’s why Kewaunee’s fume hoods are the preferred choice for laboratories:
1. Advanced Airflow Technology
Kewaunee’s fume hoods are designed with cutting-edge airflow technology to ensure optimal containment and exhaust efficiency. The precise airflow design creates a protective barrier that safely directs harmful fumes away from laboratory workers. These fume hoods maintain a constant airflow rate to protect the operator from toxic exposure and ensure that hazardous materials are safely filtered or exhausted.
- Constant Air Volume (CAV): Kewaunee’s CAV fume hoods maintain a fixed airflow, ensuring consistent protection by exhausting a set volume of air regardless of sash height.
- Variable Air Volume (VAV): Kewaunee’s VAV fume hoods automatically adjust airflow based on sash position, helping to conserve energy while maintaining the necessary face velocity for safety.
2. Durable and Reliable Construction
Kewaunee’s fume hoods are constructed from high-quality materials, such as stainless steel, polypropylene, and powder-coated steel, ensuring long-lasting durability in demanding laboratory environments. These materials are resistant to corrosion from chemicals, easy to clean, and designed to withstand the wear and tear of daily use. The robust construction ensures that the fume hood remains operational for many years, reducing maintenance costs and extending the lifespan of the equipment.
3. Energy Efficiency
With a strong focus on sustainability, Kewaunee’s fume hoods, particularly the VAV models, are designed to reduce energy consumption. By adjusting airflow based on the sash position, VAV fume hoods help lower energy use without compromising safety. This energy-efficient design not only benefits the environment but also reduces operational costs for laboratories, making it an economical choice for labs that need to manage their energy consumption.
4. User-Friendly Design
Kewaunee’s fume hoods are designed with user safety and comfort in mind. The sashes are easy to operate, and the interior is spacious enough for workers to perform their tasks effectively. The hoods feature intuitive controls and monitoring systems, allowing laboratory staff to easily adjust settings to ensure optimal performance. Clear markings and signage help ensure that users operate the fume hoods properly and safely.
The ergonomic design of Kewaunee’s fume hoods ensures that workers can access the work area comfortably without straining or working in cramped spaces.
5. Customizable Options
Every laboratory has different requirements, which is why Kewaunee offers customizable fume hoods. Whether your lab needs specific sizes, configurations, or special features, Kewaunee’s team can design and build a fume hood tailored to your needs. Custom features may include variable sash height, specialized filtration systems, or special material choices to accommodate the unique needs of your laboratory.
6. Compliance with Safety Standards
Kewaunee’s fume hoods are built to meet or exceed industry safety standards, including those established by ANSI, NSF (National Sanitation Foundation), and OSHA. With Kewaunee, you can be assured that your fume hoods will meet the highest levels of protection for your laboratory workers, ensuring that your facility stays compliant with global safety regulations.
7. Quiet Operation
Kewaunee’s fume hoods are engineered to operate with minimal noise, which is especially important in shared lab environments or teaching laboratories. The low-noise operation helps maintain a conducive work environment while still providing effective containment and exhaust.
