Can-Filters use a custom specified virgin activated Coal based carbon, (CKV4) to ensure the longest possible life in most applications. Whether for commercial, industrial, or residential use you can be sure that the proper carbon type, carbon weight, and bed width has been chosen to give full odor removal.
What makes a Max-Fan better?
- Extremely energy efficient
- Lower life time cost
- Light Weight
- Airtight housing
- Easy installation
- Internal parts optimized for aerodynamic efficiency
Do Can-Fans and Max-Fan use brushless motors?
Yes. The Can-Fans and Max-Fans use a brushless motor in their operation.
Are your fans Speed Controllable?
Yes. Both the Can-Fan and the Max-Fan line of fans are speed controllable, DO NOT SET THE SPEED OR MOTOR CONTROL BELOW 40% OPERATING SPEED TO AVOID OVERHEATING THE FAN.
The Max-Fan 12″ is not conventionally speed controlled, The Max-Fan 12″ requires the Can-Trol Speed control.
This control provides absolutely no motor hum when controlling the fan, it also gives you the option to control the voltage entering your fan, with an easy to use dial you can go from 1v to 130V with a turn of your hand, no matter what voltage you run, your fan will not hum!
Why did my fan shut off?
Can-Fans and Max-Fans are thermally protected. DO NOT SET THE SPEED OR MOTOR CONTROL BELOW 40% OPERATING SPEED TO AVOID OVERHEATING THE FAN.
How do I size the proper fan to a filter?
The formula for sizing a room: Length x Width x Height
Divided by 3
Gives minimum recommended fan CFM
Match fan to filter
Ex.) 10ft x 10ft x 20ft = 2000 Cubic Feet
2000 Cu.ft / 3 = 667 CFM
667 CFM fan is Minimum fan size for this size area
after establishing fan size, match it to appropriate sized filter. IE, Can-100
How much CFM loss is there through the filter?
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.
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
How much CFM is lost through a 25ft. Section of ducting?
Approximately 3%(Straight hard cast) to 7%(Flex Ducting)
1% to 4% Additional loss for every 90° Bend
Where is your Can-Filters and Fans manufactured?
The Can-Filters are manufactured in Beautiful British Columbia, Canada/North America
The Fans are manufactured in Germany.
What is the difference between 38-Special Can-Filter and an Original Can-Filter?
The only difference is the carbon bed thickness
38 special = 2″ Carbon bed
Original Can-Filter = 2.5″ Carbon bed
38-Special expected life = Approx. 1 year
Original Can Filter = Approx. 1.5 Years
Do I need to replace the pre-filter?
It is a good idea to replace the pre-filter when they become dirty because the pre filter is blocking larger dirt and dust particles from getting into the pore structure of the carbon, a dirty pre filter increases the pressure, which will decrease the flow through the filter.
Can my Filter be refilled?
Technically the filter can be re-filled, but it is not a good idea to self-fill the filters at all, the reason for this is that Can-Filters uses an industrial shaker with timed intervals and a dust extraction system, to ensure a packed carbon bed .This 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 and crowds in. So if you tried packing the filter yourself, as soon as you got it as full as you think you could get it, attached a fan and turned it on, the fan would vibrate the carbon, and over time the carbon would settle and you would be left with air gaps all over the place presenting the air with channels to flow through the filter and possibly leave untreated.
What is the Maximum Temperature/Humidity I can run my filter at?
The maximum recommended temperature that you can run your filter at is 80°C / 176°F
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.
How long does the filter last?
The life of a filter is determined by the concentration of the contaminant, the relative humidity and the volume of air cleaned. Unfortunately there is no indicator light on the filter that tells you when it is ready to be replaced. Experience with one Can-Filter will give you an expectation for future Can-Filters in your particular application.
Is it recommended to push or pull through the filter?
It is recommended to pull air through the filter, the reason for this is because the filters utilize the most surface area of carbon to clean the air and you use the most of the pre filter to block dirt and debris from entering your carbon pore structure. Another advantage of pulling air through the filter is that your going to have clean air running through your fan instead of air possibly laden with VOC’s, dust, and other airborne particles that could stick to the fan blades and create air resistance.
What is the Can-Filters packed bed design?
During the manufacturing process Can filters uses an industrial shaker to vibrate the filter to ensure the carbon bed is packed tight and full to the top. This process eliminates any preferential channels which would allow the odor to pass through the carbon without the proper contact time.
Can filters only uses quality activated carbon that is designed for our manufacturing process.
The CFG packed bed design filter ensures the highest quality odor control.
What are some other applications for my Can-Filter?
– VOC Removal -Waste Disposal
– Greenhouses -Hospitals
– Manufacturing -Schools
– Cleanrooms -Washrooms
– Kitchens -Paint Booths
– Pollution Control -AirPorts
– Laboratories -Fabrication
– Locker Rooms
When Air cooling lights, should you push or pull your airflow?
We recommend to push the air through your air cooled lights to avoid overheating your fan and to create a positive air pressure in your ducting and light hoods.
Approximately 150 – 200 CFM is required to air cool a 1000W Bulb.
What is the warranty on your filters and fans?
We warranty our fans for 5 years. Filters are warranted only against manufacturing defects.
How do I install a flange?
To install the flange to the filter- take the flange and gasket tape with screws included out of the package, fasten the foam gasket tape to the underside of the flange by removing the sticky tape. The tape will fit around the circumference of the bottom of the flange closer to the inside edge.Once the gasket tape is installed, center the flange on top of the filter. Use the 6 teck screws to fasten the flange to the top of the filter in a star pattern. Be sure not to torque the screws too much as air will pass through the gaps. We also have instructional videos of:
– Avoid over tightening the mounting bracket on your 8″ Max-Fan to prevent fan blade rubbing
– Avoid exceeding the fans maximum temperature rating to prevent thermal protection from tripping and de-energizing fan.
– Ensure you have at least a 1″ clearance around circumference of your Can-Filter to guarantee equal air distribution.
– Keep fingers and hands away from fan blades.
– To ensure maximum lifetime from your Filters and Fans, keep environment free of dust and debris buildup.
