The Max-Fan is the first fan that has been developed with a Computational Fluid Dynamics (CFD) program. CFDs are used for engineering aircraft propulsion engines. The perfectly designed 3D blades of the impeller and stator make this fan extremely powerful and energy-efficient. Compared with other inline fans, efficiency is 50%-100% higher. 6″-14″ come pre-wired with an 8 ft 120 V power cord. Can-Fan® bring its innovation to market and sets a new standard for performance. The Max-Fan® is a more powerful and efficient fan that takes less energy to run.
Can-Filters uses the highest grade carbon carrying the highest CTC (First, why carbon filters? Activated carbon filters have been proven an effective tool for air filtration, removing a variety of VOCs (volatile organic compounds), odors, and other gaseous contaminants. They work by a process known as adsorption where VOCs, odors, and other gaseous contaminants adhere to the carbon’s surface. Can Fan also manufactures the LARGEST and smallest filter sizes allowing for the widest range of versatility in your system design right here in North America.
All complete odor control kits come with a variable fan speed controller and flexible air ducting. Variable fan speed controllers are a great addition to your exhaust set-up for their ability to reduce fan speed when you do not need as much air removed from your space or the ability to turn up to full speed to remove more hot stagnant air and odors. Lastly, Can Fan Kits come with a flange to easily attach your filter to your fan.
Determining your requirement - Exhaust vs Recirculating (Scrubbing)
You will need to determine whether or not you are exhausting (going from a contaminated environment to a sterile environment in only a single pass through the filter) or recirculating, aka “scrubbing” (exhausting the system back into the contaminated space).
In an exhaust setting the air only passes through the filter one time so it is imperative that we remove as close to 100% of the contaminate as possible with that one chance. This requires that the contaminant have a certain time in contact with the carbon in order to be fully adsorbed. Our filters are marked with both exhaust and recirculating ratings for just this reason. If you are using this system to exhaust, DO NOT exceed the exhaust rating for the filter, the more this rating is exceeded the less contaminant will be adsorbed because the two will not have enough contact timefor adsorption to fully take place.
In a recirculating system, the contact time is not such a crucial number as we are taking contaminated air, filtering it, and releasing it back into what is typically and constantly decontaminated environment. It is for this reason that it is not necessary to remove 100% of the contaminant in a single pass. Instead we double the exhaust rating which will reduce the contact time, the goal here is to still remove a large portion of the contaminant but to get raise the cycle rate of air through the filter above the rate of emission from the source. Now, instead of removing 99.9% of the contaminant in a single pass we are getting closer to 60% but we are getting twice as many cycles through the filter in the same amount of time and over time, reducing the overall build-up of contaminant in the environment.
Sizing Your Space
Once you’ve determined the type of system you need, it’s time to size your space.
Typically for exhaust we recommend a simple length x width x height /3 calculation. This will give you the amount of air (cubic feet per minute, CFM) that you will need to move to properly ventilate your space allowing for a three-minute air exchange (all the air in the space is exchanged for fresh air every three minutes). This is the number you will match your filter to.
Room size: 10’x12’x8’ (960 cubic feet)
960 cubic feet / 3 minutes = 320CFM (Minimum recommended CFM to exchange the air every 3 minutes)
For recirculating systems, you can use the same length x width x height but divide by 1.5. This will give you a high cycle rate while still ensuring the removal of a majority of contaminant with each pass through the filter.
