The Prima Klima PK150-L inline extractor is the backbone of any healthy indoor grow. Delivering 760 m³/h through a Ø150 mm duct, it constantly refreshes the air, removes heat and humidity, and keeps your canopy in optimal conditions — while staying impressively quiet. Designed by the trusted German manufacturer, it pairs seamlessly with a Ø150 carbon filter and aluminium or acoustic ducting.

760 m³/h is the sweet spot for 1.2 × 1.2 m and 1.5 × 1.5 m grow tents with a Ø150 carbon filter inline. You refresh the full tent volume every 60 to 90 seconds — a non-negotiable for vigorous vegetative growth and dense flowering.
The balanced ball-bearing motor and powder-coated steel housing keep noise around 39 dB(A). Combine it with acoustic ducting and rubber suspension straps and the extractor becomes nearly invisible to the ear, even in a living space.
Galvanised steel shell, dynamically balanced impeller, compliant fittings: Prima Klima has been the reference for European grow shops for more than 20 years. The kind of reliability you need from a fan running 12 to 18 hours a day, season after season.
Pre-wired 230 V mains cable, ready to plug in. No electrical wiring, no controller setup: hang it from the included suspension points, connect your Ø150 ducting and start your cycle. Perfect for growers who want bulletproof performance without complexity.
The Prima Klima Ø150 pairs naturally with our Ø150 carbon filters, aluminium and acoustic ducts, and worm-drive clamps. Reach out to the BloomLED expert team to size your full ventilation set-up to your tent volume and lighting load.
BloomLED — a French growshop designed in France, with more than 10 years of expertise in indoor cultivation — selects every product for its real-world reliability. The Prima Klima PK150-L is a long-running favourite among our community of growers.
The Ø150 760 m³/h is rated for 1.2 × 1.2 m and 1.5 × 1.5 m tents (up to roughly 3.4 m³). For larger volumes, or once you add a carbon filter inline (≈30 % airflow loss), step up to our Ø160 mm 800 m³/h or an EC-TC model.
Can I connect it to a carbon filter?Absolutely — and we strongly recommend it for odour control. Pick a Ø150 mm carbon filter rated ≥ 600 m³/h. The extractor + filter + ducting chain is typically installed in pull configuration at the top of the tent.
How quiet is it really?At 39 dB(A) at 1 m it is significantly quieter than entry-level extractors. For maximum attenuation, add Ø150 acoustic ducting, rubber suspension straps and a soundproof box if the tent shares a wall with a living area.
What is the difference vs the Thermo Controller version?This 1-speed version runs at constant airflow. The Thermo Controller (TC) version includes a probe that automatically modulates the fan speed based on tent temperature — useful to save energy and reduce noise outside heat peaks.
