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.

Product features:

1. Easy to assemble; Anti-corrosion and high temperature resistance;2. Unique down return air, timely and effectively exhaust without residual;3. Special flow-equalized design makes the flow even without any blind angle;4. The internal visual range will not form condensate due to temperature difference, therefore no drip will form;5. The internal airflow direction is not affected by the volume of the exhaust air, thus will not cause turbulence;6. Low energy consumption, easy to operate;7. Has air compensation channel and connection, saves energy, comfortable;8. Drainage will not be limited by the height of the drain,since it has pump to lift the sewage;;

Laboratory fume hoods can be fabricated from different materials and include specific surface types, such as stainless steel, fiberglass, PVC or even polypropylene.

Chemical fume hoods are a mainstay for most research and educational labs. They protect users from chemical and radiological exposure. Ideal if you plan on conducting experiments that use toxic or volatile chemicals to lower the chances of inhalation.

Laminar flow hoods protect the samples from contamination. They do not offer lab personnel any protection; thus, you must not use them when working with toxic or infectious chemicals.

Demonstration or educational hoods: These are optimized for teaching. An example is the double-faced fume hoods, which have entrances on both sides, allowing for 360-degree viewing.

Biological Safety Cabinets (BSCs) have a different application and do not fall within the fume hood category. They are, however, a must-have for labs that handle viral microbes and infectious diseases.4. Detailed Photos

5. FAQ

How to Choose the Right Size for Your Fume Hood Blower

Next, you'll need to decide what size you'll need for your operations. This refers to the power of the fume hood blower and is essential to ensuring your equipment transfers enough air to keep your lab free of contamination.

It's worth noting that choosing the most robust blower is not immediately the best option. If a blower is too powerful, it could strain the ductwork and create turbulence.

Calculating the required power isn't easy. You'll need to consider the static pressure present in your duct system. This is calculated based on the diameter, duct length, number of bends, and velocity at which the fume will operate.

Talk to your manufacturer or reach out to CFI and consult a fume hood expert for the right choice.

How Many Operating Speeds Does Your Blower Need?

Exhausting tempered air from your fume hood is often one of the most costly energy uses for laboratories.

That's why depending on your operations, you might benefit from a blower with multiple speed settings that will allow you to alleviate the burden of these costs.

Intelli-sense multi-speed blowers can operate at up to three speeds which are programmed through a control box. This is located on top of the hood.

A blower with this function is very versatile. It could operate at lower speeds during the night, using the least amount of air. More extensive labs that operate on a constant volume can instead use belt-driven single-speed blowers.

The Right Material for Your Exhaust System

To ensure a safe exhaust system, you need to consider the correct material for your ductwork.

Your ducting should be compatible with local fire codes. Most importantly, make sure it's compatible with the chemicals it will be exposed to in your lab. Most commonly, duct systems will be fashioned from:

• PVC: This is intended for use with corrosives.
• 316 Stainless Steel: Suitable for use with solvents.

6. What Type of Fume Hood Fan or Blower Do You Need?

Which type of blower you need depends on the intended use. If you are venting non-toxic materials, for example, you could use a steel blower coated with epoxy.

If the purpose is to mix acids, you will need an acid-resistant blower. PVC is often the best material choice for perchloric acids and other corrosive operations.

Where the chemicals in your lab are moderately or highly corrosive, fiberglass is also a good option. If your work is volatile, there are even blowers with explosion-proofing and those that are resistant to sparks.

These fume hood blowers will often come with an enclosed motor that ensures fumes in the air stream won't encounter a spark or touch the motor.

If there's any chance of fumes in your lab catching on fire, spark resistance should prioritize.
