Overview

The Original Can-Filter is the best performing carbon filter on the market.

Each Original Can-Filter uses the most conceptually sound, pelletized carbon, packed-bed design to deliver the best performing carbon filter on the market. Even with the industry’s thickest carbon bed, at 2.5 in, the Can Original provides for some of the lowest pressure drops, even on smaller size filters. This hefty pelletized carbon bed effectively makes the Original filter the “biggest sponge” for VOC removal capable of holding massive amounts of contaminant leading to a lifespan that leaves other filters, frankly, in the dust. The Original Can-Filter is designed for the control of VOCs (paint fumes, hydrocarbons, etc…), odors and other gaseous contaminants. Built with the same proven packed bed design and pelletized virgin activated carbon Can Fan has used for 30 years, this line of time tested activated carbon air filters sets the standard for long life, consistent performance and low pressure drop. Rated at a conservative 0.1 sec contact time, the Original Can-Filter provide excellent value and confidence.

Activated carbon filters are the best way to eliminate most VOCs, gasses, and odors from the air. Combined with a fan in a ventilation system, 99.9% of noxious odors can be trapped inside the filter for good.

Through adsorption, activated carbon literally traps the carbon-based contaminants in the air that could harm you and keep them locked tight inside the filter. Using activated carbon ensures optimal pore structure and that the pathways the air travels through the filter are optimal, so that the maximum amount of contaminant becomes trapped in the filter and does not escape into the air.


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).

Exhaust

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.

Recirculating

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.

Example:
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.


Why Can-Filters?

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.

Can Fan has an extensize family of Can Fan Inline Fans for both exhaust and recirculating grow rooms that work with all Can Fan Filters. Each filter has a list of inline fans that Can Fan receommends be used with the specific filter in either an exhaust system or recirculating system.

Product Q&A

Can Fan Can Without Flange Questions & Answers

Q: How much CFM is lost through a 25 ft. section of ducting?
A: Approximately 3% (straight hard cast) to 7% (fl ex ducting). 1% – 4% additional loss for every 90˚ bend.

Q: How much CFM loss is there through the filter?
A: Every different size of filter provides a different resistance to each different size and style of fan you put on it, a filter at the maximum exhaust CFM rating has approximately 0.7 wg. pressure drop. All fans will have a lower CFM at a higher pressure. Can-Fans® and Max-Fans™ are highly efficient and lose the least amount of CFM when put under a resistance. Can-Fans® will only lose 15%–20% of their air flow through a fi lter. Max-Fans™ only lose 7%–14% of their CFM All other fans lose up to 60% of their CFM. For example at .5″ wg: The 10″ Max-Fan™ goes from 1019 CFM to 885 CFM. The 12″ Max-Fan™ would go from 1708 CFM to 1595 CFM.”

Q: How do I size the proper fan and filter to my room?
A: All Can-Filters® come with a maximum exhaust and maximum recirculation rating, as long as you do not exceed the maximum exhaust rating when matching your fan to your filter you can be confident that the air passing through your filter will exhaust out as clean air. Calculate the cubic feet of the room (Length x Width x Height) and divide that number by the number of minutes you would like to exchange the air in the room (1 – 3 minutes is recommended) that gives you the recommended minimum CFM that you need to exchange the air in that room. (Length x Width x Height) ÷ 3 = Minimum CFM Eg) 10ft x 10ft x 20ft = 2000 Cubic Feet 2000 Cu.ft ÷ 3 = 667CFM A 667 CFM filter is minimum filter size for this size area. Match fan to filter. Consult performance charts to determine which fan will meet the needs of your application.

Q: Can I push or pull through the filter?
A: You can both pull through the filter or push air through the filter. If you are going to push air through the filter it is recommended to take off the outer pre-filter and place the pre-filter prior to the air entering the carbon bed.

Q: What is the Maximum Temperature / Humidity I can run my filter at?
A: Your Can-Filter® can run at very high temperatures but it is not recommended due to potential overheating to any fans connected to the filter. Try not to run your filter for long periods at or above 70% humidity, the water molecules in the air start to get stuck in the carbon pore structure and slowly diminish the life of the filter.

Q: What is the warranty on the filters?
A: Can-Fans® and Max-Fans™ are warranted against defects in material and workmanship for a period of 5 years from the date of purchase.

Q: Do I need to replace the pre-filter?
A: It is a good idea to replace the pre-filter when they become dirty. A dirty pre-filter increases the pressure drop, which will decrease the air flow through the filter. A clean pre-fi filter will also extend the life of your filter and cause it to be more effective.

Q: Can my filter be refilled?
A: Technically the filter can be re-filled, but it is not a good idea to self-fi ll the filters. The reason for this is that Can-Filters® has the equipment and facilities to provide a truly packed bed filter. This is not possible at home. The packed bed eliminates the possibility of preferred air channels through the filter, because as we all know, air does not wait in line to go through a filter, it finds the path of least resistance.

Q: How long does the filter last?
A: The life of a filter is determined by the concentration of the contaminant, the relative humidity and the volume of air being cleaned. Unfortunately, there is no indicator light on the filter that tells you when it is ready to be replaced. Typically 12–18 months is expected of the Original Can-Filter, Although many of them have lasted much longer.
