Carbon Filter-Free Pack: Pure Ventilation for Your Indoor Grow
A carbon filter-free pack is the direct ventilation solution for your grow space. These complete kits include an extractor, ducting, and clamps to ensure efficient air exchange without odor filtration. Perfect when you're growing in an environment where olfactory discretion isn't a priority, or as a complement to other air treatment systems.
Why choose a carbon filter-free pack?
Filter-free ventilation offers concrete advantages for certain setups. Firstly, the airflow remains maximal since the extractor doesn't have to work against the resistance of a filter. The TTMAX 125 Extraction Pack thus delivers its full 280 m3/h, which makes all the difference for air exchange. Secondly, these packs are more economical to purchase and maintain – no activated carbon to replace every 6-12 months. For growers who manage odors in other ways (ozone, neutralizers) or who grow in covered outdoor spaces, it's frankly more practical. Extractors like those in the PrimaKlima packs also run more quietly without the added load of a filter.
How to choose the right carbon filter-free pack
The choice is mainly based on the volume of your space and the desired air exchange rate. For a 1m² grow tent, allow for a minimum of 200-300 m3/h. The PK160-L Extraction Pack with its 800 m3/h is perfectly suited for 2-3m² spaces. Also check the diameter: 125mm for small setups, 150-160mm for medium and large ones. The combi ducting provided in these packs combines sound and thermal insulation, a significant advantage. Consider the exhaust: unlike systems with filters, the outgoing air retains all its characteristics (temperature, humidity, odors). Therefore, you need to plan for a direct exit to the outside or a suitable technical room.
Frequently Asked Questions
Which extractor should I choose for my grow volume with this carbon filter-free pack?
To calculate the necessary power, multiply the volume of your space by 30 to 60 depending on the light intensity. A 1m x 1m x 2m (2m³) grow tent requires a minimum of 60-120 m3/h. The TT MAX 125 at 280 m3/h is suitable for up to 4-5m³, while the PrimaKlima 150 (760 m3/h) and 160 (800 m3/h) easily handle 10-15m³. Don't forget to add a 20-30% margin to compensate for pressure losses from ducts and bends. Without a filter, you benefit from the extractor's full nominal flow rate.
How do I install the ventilation system of this pack in my tent?
Installation is simpler than with a filter. Mount the extractor at the top of the tent, on the exhaust side, using straps or supports. Connect the combi ducting directly to the outlet with the provided clamp. Run the ducting to your outdoor exhaust point, avoiding tight bends that reduce airflow. Create a fresh air intake at the opposite bottom, either passive (simple opening) or active (intake fan). The 3m combi ducting provided is usually sufficient for standard installations.
Is this pack as effective at air exchange as a pack with a filter?
Yes, even more effective in terms of pure airflow. Without the resistance of activated carbon, the extractor operates at its maximum nominal power. A PrimaKlima 150 truly delivers its 760 m3/h compared to 500-600 m3/h with a filter, depending on its clogging. Air exchange is therefore faster and more constant. However, you obviously lose odor and particle filtration. This is a choice to make based on your installation constraints and discretion requirements.
How do I maintain the fans in the carbon filter-free pack?
Maintenance is minimal compared to systems with filters. Clean the extractor blades every 2-3 months with a dry brush to remove dust. Check that the bearings turn freely and grease them if necessary (depending on the model). Inspect the ducts for any tears or obstructions. Regularly check the tightness of the clamps as vibrations can loosen them. Without activated carbon to monitor, you save time and money on maintenance.
For what size tent is this filter-free pack most suitable compared to other packs?
These packs are suitable for all sizes but particularly excel in medium to large setups (1.5m² and up) where airflow becomes critical. For small grow boxes (60x60cm), a pack with a filter is often sufficient. Filter-free packs also excel in multi-space configurations where you want to centralize filtration elsewhere, or for experienced growers who manage odors with other methods (ozone generators, neutralizers). In covered outdoor spaces (greenhouses, conservatories), they are frankly more logical than versions with filters.
