Polypropylene Fume Hoods- What Are Their Advantages?

Polypropylene me hoods are made with polypropylene. It is a hydrocarbon and a versatile polymer. The polymer is widely used to prepare industrial and medical applications. The biggest advantage of polypropylene is that it is lightweight,  can provide coatings, and is also durable.

Polypropylene fume hoods are often a better choice because they offer a lightweight hood with better visibility. 

 Why is polypropylene a better choice for designing fume hoods?
 Well, if you check with attention, Polypropylene is a better choice for designing fume hoods, But, why? Here are the answers- 
  • It is a non-porous material. Hence, it creates a complete barrier and a contained and secure chamber. It prevents any fumes or odor from going outside from the chamber, Hene, the lab workers, are safe and can complete their experiments without any problem. 
  • Polypropylene is strong and durable like tempered glass. It offers better visibility and is fully transparent to view everything from outside.
  • On top of that, polypropylene is customizable, and it can be used to make fume hoods of different sizes.
  • The polypropylene fume hoods often come with superior airflow that prevents air backflow and also decreases the chance of air turbulence. 
Polypropylene fume hoods are best for clean rooms, restricted laboratory work environments, laminar flow applications, wet-processed hood labs, and other scientific research areas. In general, the polypropylene fume hood come with wires and pre-plumbed features. Hence, they are easy to install and are easier to operate also.
You can find these types of fume hoods as-
  1. Robotic fume hoods
  2. Fume lip exhaust fume hoods or wet bench-style fume hoods
  3. Laminar fume hoods
  4. Bench fume hoods
  5. Tabletop fume hoods
  6. Isolated fume hoods
  7. Slope front and sliding sash fume hoods
  8. Straight front with sliding sash fume hoods
 How a fume hood works

 Polypropylene fume hoods are closed and ventilated enclosed chambers. They contain toxic gases and vapours and protect the lab workers. The fume hoods in the past used to have an exhaust fan on top of it to pull out the air containing toxic materials. The present fume hoods are way advanced and come with HEPA or any other advanced filters to filter the poisonous air and then release it in the air.

A conventional or regular fume hood comes with a movable or sliding front sash and an interior baffle. The sash can also be different in different models. Some fume hoods have a horizontal sash, some have vertical ones and many models have a combination of horizontal and vertical sashes. These sashes create a barrier and protect the lab worker from inhaling the toxic or dangerous airborne particles.

The baffles direct the air to the filter for exhaustion. In the case of advanced fume hoods, the slots and baffles allow an even flow before exhaustion for a comprehensive and effective result. 
The baffles and slots should not be blocked. Because, if they are blocked, the air path is blocked, and air exhaustion does not work properly. The baffles are used to eliminate dead spots or the air backflow to ensure nothing toxic remains there.
There are mainly two types of polypropylene fume hoods-
  • Ductless fume hoods
The ductless polypropylene fume hoods are also called carbon-filtered fume hoods or filtered fume hoods. It is a type of filtered and self-contained lab fume hoods that do not come with a  duct. It is the more advanced fume hood. The ductless fume hoods come with HEPA filters or other kinds of filters. The air passes through these filters and gets filtered. Since the filters are advanced, the airborne toxic particles are filtered and only pure and filtered air is released.

Ductless fume hoods are better and cost-effective. It is because these fume hoods do not throw unfiltered air in the environment. Hence, they are effective in curbing air pollution to a good extent. On the other hand, they do not require ducts to pass the air. Therefore, the installation charges are lesser than the traditional fume hoods. At present, more laboratories prefer using ductless polypropylene fume hoods. 
  • Ducted fume hoods
The ducted fume hoods are traditional fume hoods that operate through a duct. It has an exhaust opening that is connected to a conduit that has an exhaust fan motor. The fan regulates air circulation and allows the sir to pass out from the fume hood through the duct. On top of that, the exhaust ensures no virus left behind. 

But, it is not ideal for the environment as the polluted air is released into the atmosphere and can cause air pollution. Additionally, the installation cost is also quite higher.
Polypropylene fume hoods are better, durable, and offer great service in a laboratory. If you want to buy the best quality polypropylene fume hoods, contact GloballabSupply.com. It is a well-known supplier of laboratory equipment and machines.
