What is Round Carbon filter?
Used to exhaust and purify the air in a limited space, filters containing activated carbon are called Round Carbon Filter.
Its purpose is to remove disturbing substances from the air, such as odors, dust, heavy metals, and undesirable and toxic chemicals.
Carbon filtration works by adsorption, trapping impurities and odors in the air in the pore structure of the carbon matrix.
Activated carbon has a very large internal surface area that adsorbs dissolved particles.
The carbon additionally acts as a reducing agent and can absorb oxidants such as ozone and chlorine from exhaust air as well as industrial and wastewater.
During filtration and adsorption, the substances to be removed are absorbed by the activated carbon and accumulated in the carbon mass.
During reduction, in contrast, the carbon is partially oxidized to carbon dioxide and thus consumed.
The number of activated carbon decreases and it must be replaced.
Solids took up by filtration increase the filter resistance.
Also, Substances absorbed by adsorption accumulate in the carbon.
Depending on the type of activated carbon and the nature of the adsorbed substances, accumulations of 10% to about 20% by weight are possible.
An activated carbon filter can be used in residential ventilation equipment to remove particulate matter from fresh air.
For range hoods, activated round carbon filters are offered for recirculating air operation to filter out odors.
For animal shelters, carbon filter removes odors from the animals’ own body odors and defecation.
Round carbon filters are also used in growing prohibited plants, such as indoor growing for marijuana, to mitigate the smell of flowering cannabis plants.
What is the main material of Round Carbon Filter
The primary and most important material for Round Carbon Filters is activated carbon.
Activated carbon or activated charcoal is a generic term that describes a family of highly crystalline carbonaceous adsorbents with highly developed internal porosity.
There is a wide variety of activated carbon products that show different characteristics, depending on the starting material and the activation technique used in their production.
It is a material characterized by a very large number of micropores (pores smaller than 2 nanometers in radius).
Activated carbon has a variety of uses: widely used in air purification, liquid filtration, impurity removal, and so on.
It is generally produced in two different methods:
A dehydrating substance, which may be an acid, is mixed with the raw material and subjected to treatment at moderate temperatures.
At the same time, this process has its drawbacks:
when using zinc chloride as a dehydrating agent, zinc residues can remain in the final product, even after washing.
Physical or steam activation:
The carbonized material is treated with a mixture of combustion gases and steam at a high temperature to activate it.
Various carbonaceous materials are used as starting materials, such as walnut shells, wood, coconut.
Activated carbon can have a surface area greater than 500 m²/g, with 1000 m²/g being easily achievable.
Some activated carbons can reach values over 2500 m²/g.
Under an electron microscope, the structure of the activated carbon shows a large number of nooks and crannies.
At lower levels, there are areas where there are small flat graphite-like surfaces, separated by only a few nanometers, forming micropores.
These micropores provide the conditions for the adsorption process to take place.
Unitgrow produces carbon filters with a point value of 750m²/g, and we can also use carbon with higher adsorption values depending on the customer’s needs.
What’s the Function of Round Carbon Filter?
Carbon filters, also known as carbon scrubbers, are particularly useful in filtering the smell of flowering cannabis plants growing in planting rooms or tents.
Carbon filters are handy in removing the pungent smell of cannabis plants in planting rooms or greenhouses. In general, they are installed in the ventilation system and connected to the fan through ventilation ducts.
The carbon filter perfectly protects your privacy.
It doesn’t change the smell of marijuana, but it completely prevents the smell of marijuana plants from leaking from growing tents.
The internal fan expels the smell of the plant out of the planting room and traps the smell through a carbon filter so that the plant’s aroma is not released to the outside.
The carbon filter is efficient and durable and needs to be replaced after the activated carbon becomes full.
Unitgrow offers customized carbon filters in various sizes and shapes, including cylindrical and flat, widely used in any exhaust system used by growers.
Where is the Round Carbon Filter used?
a. When you became a fan of herbs and started growing herb, you didn’t think that the room would be filled with a unique smell that made you uneasy.
You begin to worry about whether neighbors will come to visit later or whether friends will come to the house for a party today.
You only need to add a talking filter to the ventilation system to solve all the problems, and the annoying smell disappears.
b. When you start to keep a cute dog, keep it in the garage. The next day, when you enter the garage, you find the smell so unacceptable that you don’t even want to go in and drive your car. At this time, you only need to add a filter to a ventilator to solve the smell problem.
c. When you decorated the office, just went in, a strong smell of paint filled the air. Sitting in the office for a long time, you felt a little dizzy when you stood up.
I would strongly advise you to install a fan and carbon filter as soon as possible.
d. Every time you go home, when you think of cooking, you will lose your enthusiasm when you are filled with oil fumes and smell of oil fumes.
I think you need to add a filter to absorb the smell of the lampblack fully.
Carbon filtering has a wide range of applications because it is light and easy to install and has a long service life.
How to pack the Round Carbon Filter before shipping?
Package Includes: 1 x Carbon Filter; 1 x Changeable Pre-filter; 2 x Carbon Filter Belts.
Both ends of the carbon filter are fixed with thickened elastic foam. Elastic foam protects both ends of the filter from deformation caused by impact. At the same time, they can also position the filter to prevent the filter from shaking, resulting in toner leakage.
The whole filter will be packed in a transparent, thickened OPP bag to ensure that the entire carbon filter will not rust due to moisture and ensure the stability of the activated carbon.
Finally, we use thickened 5-layer cartons to ensure that the goods transported over long distances are intact.
How to check the Quality of a Carbon Filter?
1. Check whether the outer package is damaged; long-distance transportation is easy to filter due to violent transport caused by impact deformation.
2. Check the flange of the filter, the flange deformation is easy to occur in transportation.
The deformed flange becomes very difficult to connect to the ventilation duct.
3. Check the surface of the filter. The surface of the filter is prone to indentation caused by impact.
4. Check the dryness of carbon, the activity of carbon will decrease after being exposed to moisture, and the drying of activated carbon must be ensured.
5. Check the connection between the flange and the main body of the filter. If the position of the rivet is not firm, it may cause the flange to fall off.
What size is the Round Carbon Filter?
Does a Round Carbon Filter have to Vent outside
Carbon filters are easy to install and only take a few minutes.
Hang the filter on the plant or the floor next to the plant and connect it through an air duct.
If you have installed an exhaust fan for your hydroponic garden, you can directly install a carbon filter to connect to it.
Because there is a charcoal fiber scrubber inside the filter, it can be used in front of any ducting fan. The filter is connected to the input side of the fan.
You can use matching hoops, and aluminum foil glue to bring a fixed filter, cut a section of aluminum foil pipe, and connect the filter to the fan.
When using this method, one thing to pay attention to is to check that the filter is placed at a sufficient distance above the plant.
This ensures that the air circulates the plant before it is filtered.
How to replace the filter
The filter has a service life, and after a long time of use, the pores of the carbon filter are filled with pollutants, and it loses the function of air circulation and odor removal.
When this happens, you need to replace the new filter.
Most carbon filters need to be replaced about 12-18 months after installation.
