Systemair ‘Carbo Air 100’ High Quality Carbon Filters

£397.99 – £459.99 incl. Vat
CarboAir 100 has been developed to filter very high concentrations of VOCs from larger grow rooms.
CarboAir 100 has a huge 100mm bed of virgin activated carbon and a 1 metre body. This, coupled to our industry leading steel mesh is the most effective filter in the industry. These filters are monsters, designed for the most demanding environments. if you need to clean very large volumes of air or large amounts of unwanted smells, this is the filter for you.
  • Removes even the strongest odours
  • Handmade in Europe
  • Comes with a machine washable pre-filter
  • 18 month guarantee
VIRGIN ACTIVATED GRANULAR CARBON The virgin carbon is activated at temperatures above 1000°C in a humid environment. The process opens the pores of the carbon to give it incredibly high absorption properties of organic particles and other airborne pollutants. The carbon is produced to very high standards in Europe, unlike Chinese filters which often contain cheaper blends and risk water contamination during shipping. Being produced in the EU enables better quality control.The carbon is produced to EN12915 which means it is pure enough to be used in food and drink applications. The size and depth of our filter has been specially designed to provide the correct contact between the contaminated air and carbon.The carbon is double sieved to remove any dust particles which would restrict air flow. Each CarboAir filter is guarantee to a minimum of 18 months because the carbon is pure.All filters are batch tested at source to make sure it passes our quality requirements. FILTER HOUSING The filter mesh is 55.5% open for the best air flow through the filter. Carboair filters have better flow rates, enabling them to utilise a thicker carbon bed compared to competitors. The top flange and bottom flange are preformed and made of the same strong galvanised steel. The carbon is machine packed as tightly as possible into the housing without crushing the carbon granules. The carbon is placed into the casing and put on tremor plates that have precise frequency to vibrate the carbon into a tightly packed uniform filter. A high density foam collar is placed onto the carbon bed before a top plate is added on top of the foam collar. This is then machine compressed, reducing the foam collar to less than 5mm thick. This unique process ensures the carbon will not move or settle. A top flange is fitted, this compresses the carbon further. The whole process is carried out by hand and visually inspected during each stage. The carbon filters are then packed directly into bags and boxed in the factory ready for shipping guaranteeing you receive the best quality filter every time.It has an industrial galvanised steel filter casing. Using the highest quality materials enabled it to use the finest mesh.

What is a Carbon Filter?

Activated carbon filters are also known as activated charcoal filters. They are used to combat volatile organic compounds that are released into the air from common household products. Carbon filters use a process called adsorption to clear impurities and eliminate strong odours. Using a hydroponic carbon filter in your grow room, contaminants and pollutants stick to the carbon and cleanse the air.

Types of Carbon Filters

Active carbon filters come in two varieties, each with their pros and cons. There are granular activated carbon filters and solid block carbon filters. Granular carbon is carbon that has been ground into small particles. Solid block carbon has a larger surface area and is made by grinding the carbon into a fine powder, then pressing it into a block form. Both kinds of filters are great for odour removal. Both of these types of carbon filters can be used for water filtration using a reverse osmosis system.

How Effective are Carbon Filters?

Carbon filters are effective for filtering contaminants and fighting volatile organic compounds also known as VOCs. VOCs are gaseous substances released into the air from common products such as cleaning products, paint or tobacco. Most other air filters such as HEPA filters do not clean the air of VOCs and the odours will remain in your space.

The premium range tends to have a slightly deeper carbon bed.

They are also useful in controlling humidity as well as unpleasant odours, and so helping to keep your growing environment consistent when paired with an extraction system for fresh air.

Carbon Filters in a Grow Room

Growers often find that their grow tents or grow rooms have strong unwanted odours. Activated carbon filters can scrub the air and take care of the odour problem. Additionally, airborne pathogens have been known to ruin the entire yield of plants. An activated carbon filter can eliminate these contaminants from the air thus preventing diseases from affecting the plants.
