Balanced motor with permanently lubricated ball bearings for vibration-free operation and continuous running.
Advantages of Coconut Shell Activated Carbon Filter: Better than other general charcoal filters.
Tips: Effective treatment requires the exchange of air in your growing area in a period of several minutes.
The 6" Inline Duct Blower & Activated Carbon Air Filter can eliminate odors, filter particulates and purify air efficiently.
With the same iodine value, the filtering effect of coconut shell active carbon is the best. There are many calculations on the web for sizing a fan for ventilating grow rooms; however, what these calculations fail to take into consideration is the friction loss on carbon filters, increased temperatures from HID lights and CO2, etc. The fan should be able to adequately exchange the air in a grow room once every three minutes. In our 8’ x 8’ room we have 2 x 1000w air cooled lights, and we plan to use a carbon filter.
If you want to keep things really simple, just remember that you want to replace the air in your grow room every one to three minutes. It is very important to understand that you can’t simply put an exhaust fan in a sealed room and expect to suck air out of it. One last note about intake ports – you will see much better results from your exhaust system if you install a second fan to create an active (as opposed to passive) intake system. Normally, when your exhaust fan sucks air out of your room, air is passively going to get sucked back into the room.
If no carbon filter is being used then place the fan at the highest possible point in the room; the reason for this that hot air rises and it is the hot air that needs to be exhausted. There are two options that a grower can use with the carbon filter: 1) Suck through the filter or 2) Blow through the filter. Carbon filters should be placed on the floor standing upright or hung horizontally from the ceiling. Before using a carbon filter for the first time always take the filter outside and then first suck, then blow through it before installing it in your growing area. Now that we are in the grips of a hot summer, one of the most frequently asked questions from our customers is on cooling HID (High Intensity Discharge) lighting systems.
Air-cooled lighting involves the use of inline fans and ducting to extract heat away from the lamp and out of the growing area. This type of cooling system pulls air (preferably from a cool air source) through the lights and exhausts it outside or into another area.

If you are running with hot HID grow lights you will need to change the air within the grow room once a minute for good optimum results.
Its full of proven goodies that we know can help you get the best out of your cannabis grow! With 100% of the coconut shell carbon element utilization and 720 CFM airflow rate, this combo makes the living environment of you and your plants cleaner and fresher. You can count the total cubic feet with multiplying length by width by height of your growing area.
With 100% of the coconut shell carbon element utilization and 353 CFM airflow rate, this combo makes the living environment of you and your plants cleaner and fresher. The calculations that are used to correctly design a ventilation system can be quite complex and require numerous known variables. Ambient temperature – for hot climates (such as Southern California) add 25%, for hot and humid climates (such as Florida) add up to 40%.
You absolutely must have some kind of opening in the room to allow fresh air to replace the air you are exhausting.
By installing a second fan on the intake side, you will reduce the amount of negative pressure created in the grow room, thereby cutting down greatly on the amount of work the exhaust fan has to do and allowing much more air to pass.
The benefit is that the fan can be placed at the highest point in the room and the hot air is sucked out of the room and forced through the filter. Air circulation within the room eliminates stale spots and also reduces the formation of micro-climates within the leaf canopy. All air-cooled reflectors sold by BGH can be sealed with a tempered glass lens, isolating the heat of the lamp from the cooler environment of the grow room.
By air cooling the lights, you can reduce the temperature of the grow room enough so that you don’t need an exhaust fan, or at the very least, get away with a small air conditioner.
Due to the small volume of air in the reflector (compared with the entire volume of the grow room), much less energy and effort is required to remove the same amount of heat. In this setup, the system used to air cool the lights is also used to ventilate and clean the air being exhausted from the grow room. The air passing through the light never comes in contact with CO2-rich air in the grow room. You've read and agreed to the Global Shipping Program terms and conditions - opens in a new window or tab. Import charges previously quoted are subject to change if you increase your maximum bid amount. If you are suffering from stale air condition and tired of gardening with organic fertilizer, sprays, odor gels or even incense, get this combo and you will be set free from the fidgets referred above. Then divide by the CFM(cubic feet per minute) of the fan, you will get the time that the fan exchange the air for your grow area. The purpose of this article is to simplify these calculations while helping you to better understand grow room ventilation.


The ambient temperature is 90°F, however, we will be using air from another room that is air-conditioned.
Ideally, the intake fan should be the same size as the exhaust fan, but it can be a little smaller if necessary.
The negative pressure that the fan creates in the room will pull air from the intake opening across the garden and towards the fan. During normal operation always keep the dust sock on the filter; this stops large dust particles from blocking the filter and will help prolong the life of the filter.
If air circulation in the grow room is poor then the micro-climate in between the plants increases in humidity and temperature. The main purpose of utilizing an air cooling system for HID lights is to efficiently extract the heat produced by the bulb before it has a chance to pass into the growing area. If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable.
For example, if the size of your grow tent is 15' length x 15' width x 15' height, it contains a total of 3375 cubic feet. For example, if the size of your grow tent is 12' length x 12' width x 12' height, it contains a total of 1728 cubic feet. If you were to poke a small hole somewhere in the straw, you will find that you can now suck air through it; the bigger the hole, the more air you can suck. Obviously, any fan you install in your grow room isn’t going to be powerful enough to create enough negative pressure to suck the walls inward, but what will happen is that your fan will draw more energy, make more noise, run hotter, break down much sooner than it should, and finally, suck very little (if any) air out of the room.
Keeping the ducting as short and as straight as possible will reduce the friction loss and noise. For adequate air circulation use a wall mounted fan; 2-3 fans will provide sufficient air movement. The fan will need to pull air through a carbon filter, through one or more lights and exhaust the hot air. An intake port can be anything from a gap under the door to an open window – even a hole in the wall. The fan should be running continuously during the light period (which means it is possible to plug the fan into the same timer that is used to operate the lights [provided they both don't exceed the amperage rating of the timer]). Ideally, the fan should stay on a little longer, since it takes a while for the bulb, reflector, ducting, etc. With the addition of a 6″ ZoneMaster Motorized Damper on the intake side, you will get the added benefit of keeping moisture and dust from entering the system at night, which could cause condensation and alter the temperature and humidity levels in the grow room as well.
This gets installed in-line with your ducting and is plugged into whatever device controls your exhaust fan.
When the lights turn on and the fan is activated to cool the lights, the Zone Control Damper is also activated, thus allowing cooler intake air to cool the lighting system. Alternatively, you could install a 6″ Suncourt inline booster fan on the intake side in place of the damper. When the lights turn on and the fan is activated to cool the lights the booster fan is also activated, creating positive pressure in the air cooling system and increasing the air flow and efficiency of the system.
This is especially useful if you decide to add another light in the future or you find that the single fan system isn’t moving enough air (which is a common problem when you use too much ducting or too many sharp bends in the duct run).
