G-Tools PK2601 Eco Carbon Filter 360 m³/h

The G-Tools PK2601 is the factory-specified carbon filter for the Bonanza 1 m² grow cabinet. It pairs directly with GT 125 extraction fans and keeps odours under control for up to eight months.

This filter is built specifically for growers running a G-Tools Bonanza 1 m² cabinet. The 125mm collar matches the GT 125 extractor fan without adaptors. Airflow is rated to 360 m³/h, which suits the Bonanza's internal volume comfortably.

The carbon charge is rated for eight months of active use under normal growing conditions. That is a realistic figure for a single-tent or cabinet setup running a standard photoperiod cycle. After eight months, odour control typically starts to degrade - replace the filter rather than push it further.

A washable pre-filter sleeve wraps the outside of the unit. This catches dust and airborne particles before they reach the carbon bed. Keeping the pre-filter clean extends the working life of the carbon itself. Rinse it every four to six weeks in a busy grow.

If you are building a G-Tools Bonanza system from scratch, this filter and a GT 125 fan are the correct pairing. The combination handles extraction and odour removal in one straightforward ducted circuit. It also fits any other 125mm ducted extraction setup where 360 m³/h of filtered airflow is sufficient.

Grower’s Note: Carbon filters perform best when airflow passes through the carbon bed slowly enough for adequate contact time. Running your fan at full speed continuously reduces that contact time and shortens filter life. Use a fan speed controller to dial the GT 125 back to the minimum speed that still maintains negative pressure in the cabinet. Your carbon will last noticeably longer.
