You fine-tune the air exchange in your grow tent (220 m³/h for vegetative growth, 400 m³/h for full flower) while neutralising 100% of odours thanks to the RC4-12 activated carbon. BloomLED, the French growshop specialist for over 10 years, hand-picked this duo for its unbeatable value and proven longevity.

Switch from 220 m³/h for cuttings and vegetative growth to 400 m³/h during full bloom. You adapt air exchange precisely to your plants without buying an extra speed controller.
The RC4-12 granular activated carbon blocks 100% of odour-causing compounds. Ideal for discreet growers — no neighbour will know your grow tent is running at full power.
A trusted reference brand for over 25 years, Prima Klima builds fans with ball bearings and copper motors rated for more than 30,000 hours of continuous operation.
Steel housing, rubber suspension and aerodynamic blade design minimise vibration. On speed 1, the PL125-2 is barely audible — essential comfort for home cultivation.
Everything is ready: pre-wired fan with EU plug, mounting collars, carbon filter with pre-filter installed. Hook it up with silent blocks (sold separately) and start in 10 minutes.
BloomLED tests every product under real grow conditions. Our team helps you size your ventilation by phone or email so you get the most out of your PL125-2.
The PL125-2 is ideal for grow tents up to 1.2 × 1.2 × 2 m (around 3 m³). At 400 m³/h, a full air exchange happens in under 30 seconds, well above the 1–3 minute target recommended for indoor cultivation.
Is the carbon filter effective against strong odours?Yes. The RC4-12 activated carbon used by Prima Klima is one of the highest-performing carbons for capturing volatile organic compounds responsible for intense odours. With a 12–18 month lifespan in continuous use, it guarantees full discretion throughout your cycle.
What is the difference between speed 1 and speed 2?Speed 1 (220 m³/h) is perfect for cuttings and early vegetative growth, when little heat is generated. Speed 2 (400 m³/h) takes over during full bloom, when LED or HPS lights produce more heat and humidity must be controlled more aggressively.
Do I need a silencer or rubber suspension?The PL125-2 is already engineered for low noise. However, hanging the fan with silent blocks (rubber straps) cuts vibrations roughly in half. For a grow room next to a living area, adding a Ø125 acoustic silencer (sold separately) further dampens the airflow noise.
How do I install the pack in a grow tent?Hang the carbon filter high inside the tent with straps, connect it directly to the fan inlet (Ø125 collar), and exhaust filtered air outside through aluminium ducting. The order filter → fan → duct is critical: the filter must always be on the suction side, never on the push side.
The matched Prima Klima combo: by choosing this dual-speed pack with filter, you avoid common sizing mistakes between fan and carbon filter. BloomLED has calibrated both components to work together at full capacity, with no saturation or airflow loss.
