Canada Laminar Flow Hood Models
You can choose from one of the standard models or request a custom size laminar flow hood from us. We can produce a hood that fits the space you have available. Feel free to inquire if you think that our standard models do not fit your needs. Do not worry if you are not a 100% sure what kind of a machine you need in your line of work. Once we start communicating, it will be clear what may be the best cost effective solution. We will prepare a short, one page proposal and a drawing outlining how we intend to realize your idea. It will include costs and estimated time-frame.
What determines the cost?
There are several factors that greatly affect the cost of a custom laminar flow hood. Some things to keep in mind are the size of the filter, the speed and the level of comfort. In general, the bigger the filter, the higher the cost. This is because more air needs to pass through a larger area in order to achieve the same speed. When we need to push more air through a larger filter we need to install a more powerful blower. However, we have managed to achieve lower noise levels in our latest models.
What is the difference between a vertical and a horizontal laminar flow hood?
The difference between a horizontal laminar flow hood and a vertical model is in the location of the filter. In the vertical model, the clean air is flowing down, while in the horizontal model, the air is flowing toward your body. You can choose between the models based on the space you have available and whether you plan to work primarily with liquids. A vertical flow hood takes up less footprint on the bench and having the filter on top, it is less likely that you will spill any liquid on the filter.
What determines filtration efficiency?
Filtration efficiency is determined by the grade of the filter. Learn more about HEPA filtration efficiency. We can produce machines with either an H13 or H14 filter.
Why is testing done?
This is the most confusing thing that new hood owners face. A novice is led to believe that spending more money is directly proportional to more “safety”. You can test your machine to check the efficiency of the HEPA filter and also air flow. The regulatory body of a professional organization can choose which recommended standard their membership should follow and how often they should test the hood.
