At BloomLED, an indoor-growing expert for more than 10 years, we know that controlled ventilation is the backbone of a healthy grow space. The Prima Klima WHSP silent air extractor (Whisperblower) is engineered to renew the air in your grow tent without ever giving your setup away: up to 530 m³/h of airflow with remarkably discreet operation. Thanks to its shock-resistant polyamide housing and its refined aerodynamic design, this Ø125 mm, 3-speed model combines performance, energy efficiency (57 W) and long service life. Built for demanding growers, it fits equally well in a compact tent or a larger indoor lab, and pairs perfectly with a carbon filter for complete control over odours and temperature. A reliable workhorse that keeps your climate stable season after season. Our experts recommend sizing your extraction with a little headroom: a higher airflow set to a mid speed stays quieter than a small extractor pushed to its limit. Its 300–530 m³/h range covers the vast majority of tents from 60×60 to 120×120 cm, and the BloomLED team, based in France, will help you pick the extractor and filter pairing best suited to your space. Whether you are setting up your very first grow tent or upgrading a multi-tent room, the WHSP delivers the quiet, dependable air movement that keeps humidity in check, prevents hot spots and gives your plants the fresh, CO₂-rich air they need to thrive.

Installation is straightforward: connect the extractor to your Ø125 mm ducting, position it in extraction mode (air out) at the top of the grow tent and link it to a carbon filter at the intake to trap odours. For automatic regulation, plug it into a thermostat socket that adjusts the speed according to temperature. Simple upkeep — regularly dusting the blades — is enough to preserve its airflow and quietness year after year, making the WHSP a lasting investment for your indoor grow.
Three speeds (300, 420 and 530 m³/h) let you match air renewal precisely to the size of your grow room and the stage of your plants, from vegetative growth through to flowering.
The Whisperblower lives up to its name: acoustic engineering makes it up to 2.5× quieter than a conventional extractor — a major advantage for a discreet indoor grow at home.
Drawing just 57 W for 530 m³/h, Prima Klima’s optimised AC motor delivers an excellent airflow-to-power ratio and keeps your electricity bill under control over long cycles.
The polyamide housing resists impacts and corrosion, ensuring a long lifespan even in warm, humid environments, with continuous operation rated up to 50 °C.
The speed selector adjusts output with no extra accessory; combine it with a thermostat or controller for even finer automatic climate regulation.
The standard 125 mm diameter matches most carbon filters, ducting and couplers on the market, for fast assembly and an installation that grows with your needs. Reducers and couplers let you adapt it to Ø100 or Ø150 setups when required, so a single extractor can follow your grow room as it evolves.
Aim for a full air change of your space every 1 to 3 minutes. For a 1–1.2 m³ tent the first speed is often enough; larger tents or setups with a carbon filter will benefit from the full 530 m³/h. The 3 speeds give you plenty of room to fine-tune.
Is it really silent?Yes. The WHSP’s aerodynamic design and sound insulation make it up to 2.5× quieter than a standard extractor of the same airflow. For near-total silence, add an acoustic duct and lower the speed at night.
Can I use it with a carbon filter?Absolutely. The Ø125 mm diameter is compatible with Ø125 carbon filters such as the Prima Klima PITPUK. Choose a filter whose capacity matches the airflow to keep odour neutralisation at its best.
Can the speed be regulated automatically?The AC motor works with thermostats and speed controllers. Wired to a thermostat plug, the extractor speeds up as the temperature rises and slows once the target is reached, for a stable climate and controlled consumption.
How long will it last?With its shock-proof polyamide housing and robust Prima Klima AC motor, this extractor is designed for intensive, long-term use. Regularly dusting the blades and motor further extends its lifespan.
Premium ventilation, mastered silence: the Prima Klima WHSP Ø125 mm is the ideal ally for growers who want performance without compromising on discretion. Selected and shipped by BloomLED, an indoor-growing expert for over 10 years, it ships fast and comes backed by our specialist support.
