Can-Lite 300

The Can-Lite 300 carbon filter delivers 300 m³/h practical capacity in a lightweight 1.8 kg plastic housing, making it the most versatile model in the Can-Lite plastic range from Can-Filters. Optimised for grow tents from 80x80 to 100x100 cm and perfectly matched to the most popular 125 mm inline fans on the market. With 1.2 kg of Australian activated carbon distributed across a uniform 2.5 cm bed, this filter removes up to 99 percent of odours from your grow space effectively. Washable pre-filter included to extend carbon bed lifespan by 30 to 50 percent. Flange sold separately in 100 or 125 mm diameter.

Can-Lite 300 Carbon Filter — The Versatile Standard for Mid-Size Grow Tents

The Can-Lite 300 occupies the sweet spot in the Can-Lite plastic range: enough airflow capacity to handle the most popular tent sizes from 80x80 to 100x100 cm, packaged in a lightweight 1.8 kg ABS housing that hangs effortlessly in any grow setup. At 300 m³/h practical capacity, this is the filter that fits the majority of hobby and semi-professional growing operations.

Filtration Performance Data

Inside the 45 cm long housing, 1.2 kg of Australian low-density activated carbon is distributed via vibration filling across a uniform 2.5 cm bed. This technique eliminates channelling — the phenomenon where air bypasses portions of the carbon layer through gaps or loose spots. The technical capacity of 330 m³/h provides 10% overhead above the practical rating, ensuring consistent odour removal even as the pre-filter accumulates particulate matter over time. Can-Filters sources exclusively Lite-grade Australian carbon for the entire range — the same premium raw material used in every Can-Lite model.

  • ABS plastic housing: lightweight, corrosion-resistant and durable under the humid conditions typical of active grow environments.
  • 51% open perforation: engineered for optimal airflow-to-resistance ratio, keeping fan energy consumption low.
  • Refillable after saturation: replace spent carbon instead of the entire filter unit, reducing cost per cycle.
  • Washable pre-filter included: extends effective carbon bed lifespan by 30 to 50 percent through dust interception.

Matching the Right Fan

The Can-Lite 300 performs best with an inline fan delivering 250 to 330 m³/h on a 125 mm connection. The 125 mm extraction fan suits smaller tents where full filter capacity is not required, while the Prima Klima 360 m³/h maximises the filter's rated capacity. Always run in pull configuration — fan downstream of the filter — to maintain negative pressure and prevent unfiltered odour escape through leaks.

Flange Required

Like all plastic Can-Lite models, the 300 ships without a flange. Select a 125 mm flange for most standard setups or a 100 mm flange for compact systems. The flange seats directly into the filter and connects to ducting via a hose clamp for an airtight seal. After installation, verify all joints with a smoke test — any leak reduces your filtration effectiveness proportionally.

Maintenance for Maximum Service Life

Clean the pre-filter monthly with cold water and maintain humidity below 70% for maximum carbon adsorption efficiency. A dirty pre-filter increases pressure drop across the system and forces your fan to work harder while delivering less effective airflow through the carbon bed. Replace the pre-filter sleeve after eight to twelve wash cycles when the fabric no longer captures fine particles effectively. Store spare filters dry and sealed in original shrink wrap for shelf life up to five years — activated carbon degrades when exposed to ambient moisture even without active use.

Which fan pairs best with the Can-Lite 300?

Select an inline fan rated between 250 and 330 m³/h with a 125 mm connection. The Prima Klima 360 m³/h is an excellent match that utilises the full filter capacity without overloading it. A 125 mm extraction fan at 185 m³/h also works well for smaller tents where you do not need the full rated airflow.

How does the Can-Lite 300 compare to the Can-Lite 150?

Both filters share the same 14.5 cm diameter and 2.5 cm carbon bed, but the 300 is longer (45 vs 25 cm) and contains more activated carbon (1.2 vs 0.7 kg). This results in double the airflow: 300 versus 150 m³/h. Choose the 150 for tents up to 60x60 cm and the 300 for tents from 80x80 to 100x100 cm.

Do I need a reducer if my fan is 150 mm?

The Can-Lite 300 accepts flanges of 100 or 125 mm. For a 150 mm fan you will need a 150-to-125 mm reducer. Bear in mind that each diameter reduction adds airflow resistance. If your system runs at 150 mm throughout, consider the Can-Lite 600 which features a built-in 160 mm flange and eliminates the need for reducers entirely.

Can the Can-Lite 300 be mounted vertically?

Can-Filters recommends horizontal mounting for the most even air distribution through the carbon layer. Vertical mounting is possible but may cause uneven carbon compaction due to gravity over time, gradually reducing filtration performance. If you mount vertically, rotate the filter periodically to maintain even carbon distribution and consistent adsorption efficiency.
