The Prima Klima PK125-L Ø125 mm inline duct fan delivers a steady 360 m³/h airflow, perfect for refreshing the air in a grow tent or room up to roughly 1.2 × 1.2 m. Pre-wired with a European 230 V plug, it installs in minutes and keeps your climate healthy: heat evacuation, humidity control and fresh O₂/CO₂ exchange for vigorous plants from cloning to bloom.

Sized for tents from 1.0 × 1.0 m up to 1.2 × 1.2 m, or as an intake fan for a larger setup. Full air change every 1 to 2 minutes depending on the room volume.
Pre-wired with a European 230 V plug, the PK125-L runs straight out of the box — no speed controller required. Fits every standard Ø125 mm clamp, ducting and carbon filter.
A European reference for over 20 years, Prima Klima uses an asynchronous ball-bearing motor: long lifespan, stable operation and minimal maintenance over multiple grow cycles.
Evacuates lamp heat, regulates humidity and renews CO₂ for healthy photosynthesis. Pair it with a carbon filter to fully neutralise bloom odours.
With 360 m³/h, it comfortably ventilates 1.0 × 1.0 m to 1.2 × 1.2 m tents (around 2 to 3 m³). For 1.5 × 1.5 m or hot climates, upgrade to a 2-speed model or a Ø150 mm fan.
Do I need a carbon filter with it?Yes for the bloom phase: a Ø125 mm carbon filter wired in series removes 99% of odours. Choose a filter rated for at least 360 m³/h to avoid throttling the fan.
How quiet is the fan?The PK125-L runs at a single fixed speed at around 45 dB at 1 m. For near-silent night operation, add a Ø125 mm acoustic muffler on the intake side.
The right pick for a first indoor setup: rugged, no tuning needed, ready to plug — Prima Klima takes care of your climate while you focus on your plants.
