CAN Lite Carbon Filter 3500m³/hr – 1m – 315mm (12″)

High-Capacity Odour Control for Large Ventilation Systems

The CAN Lite Carbon Filter 3500m³/hr – 315mm (12″) is a high-performance air filtration solution designed to remove unwanted odours from large indoor growing environments. Built with the trusted filtration technology developed by Can Filters, this lightweight carbon filter uses high-quality activated carbon to effectively capture and neutralise airborne odour particles before the air is expelled from your ventilation system.

With a maximum airflow capacity of 3500m³/hr, this filter is ideal for large grow rooms, commercial cultivation spaces, and high-output extraction systems. Its 1 metre body length provides a large carbon bed, allowing for extended contact time between the air and the carbon granules, which improves filtration efficiency and helps maintain effective odour control throughout the grow cycle.

The 315mm (12-inch) flange connection makes it compatible with high-capacity extraction fans and large-diameter ducting systems commonly used in professional ventilation setups.

Despite its large capacity, the CAN Lite series is designed to be lighter than traditional steel carbon filters while still maintaining strong durability and consistent airflow performance. This makes installation and handling easier, particularly when mounting filters above grow areas.

• Pre-fitted flange connection

• Pre-filter sleeve (white dust sleeve) to capture larger particles and extend carbon life

How to Use the Product & Best Usage Recommendations

Installation

The carbon filter is typically installed inside the grow room at the start of the extraction system, allowing air to pass through the carbon before entering the ducting and extraction fan. Connect the 315mm flange directly to compatible ducting or to the intake side of a matching extraction fan using a suitable clamp or duct connector.

For best results:

• Install the filter as high as possible in the grow space, where warm air and odours accumulate

• Ensure the fan’s airflow rating does not exceed the filter’s maximum capacity of 3500m³/hr

• Use secure mounting straps or brackets when suspending the filter from the ceiling

Maintenance

The included pre-filter sleeve should be checked periodically and cleaned or replaced if it becomes heavily clogged with dust. This outer sleeve helps prevent large particles from entering the carbon bed and extends the lifespan of the filter.

Over time, the activated carbon will naturally lose its ability to adsorb odours. Depending on humidity, airflow levels, and operating hours, carbon filters are typically replaced after 12–18 months of continuous use.

Best Usage Recommendations

• Pair with a high-capacity 12″ EC or AC extraction fan capable of handling airflow close to the filter’s rated capacity

• Use quality ducting and airtight connections to prevent odour leaks

• Maintain relative humidity below 70% in the grow room for optimal carbon performance

• Avoid exposing the filter to excessive moisture or direct water contact

The CAN Lite carbon filter provides reliable odour control for large-scale indoor growing setups, helping maintain a discreet and clean ventilation system.
