VENTILATION

Prima Klima WHSP 460 m³/h silent extractor: discreet, high-performance airflow

Built for demanding indoor growing, the Prima Klima WHSP (WhisperBlower) Ø125 mm inline extractor pairs a generous 460 m³/h airflow with one of the lowest noise levels on the market. Its AC ebm-papst motor and fully redesigned aerodynamic profile create more pressure with less noise than a conventional fan — dependable air exchange for your grow space, without the distracting hum.

Prima Klima WHSP silent air extractor 460 m³/h Ø125 mm

The WhisperBlower line was engineered together with German motor specialist ebm-papst, a global benchmark in ventilation. The result is a professional-grade extractor that moves air efficiently while staying remarkably quiet — up to 2.5 times quieter than a standard AC motor of equivalent output. At BloomLED, a French growshop and specialist in horticultural lighting and ventilation for over 10 years, we chose this model for its reliability and its outstanding performance-to-silence ratio.

Why choose the Prima Klima WHSP extractor?

🔇 Unmatched running quietness

The essence of WhisperBlower technology: a re-engineered airflow that sharply cuts turbulence and therefore noise. Ideal for discreet indoor growing, in an apartment or a dedicated room, so the sound of extraction never becomes a daily nuisance.

⚙️ Premium ebm-papst motor

Prima Klima fits the WHSP with an AC motor from ebm-papst, Germany's ventilation reference. Rugged and enduring, it delivers an 80,000-hour service life while drawing a modest 52 W.

🛡️ Tough polyamide housing

The UL94-certified polyamide casing is impact-resistant, durable and flame-retardant. The built-in connection system makes mounting onto Ø125 mm ducting easy and guarantees a clean, secure installation that lasts.

🌬️ Optimised airflow, no extra draw

Thanks to its aerodynamic shape, the WHSP produces more static pressure at the same power: 460 m³/h is enough to efficiently refresh the air of a grow tent or a small growing space, in both vegetative growth and flowering.

🌿 Designed for carbon filters

The extractor is optimised to run with a Ø125 mm activated carbon filter: you keep flowering odours under control while maintaining strong airflow, for a fully discreet indoor grow.

Frequently asked questions

What size space is this extractor suitable for?

With 460 m³/h, the WHSP Ø125 mm comfortably covers a standard grow tent (up to roughly 120 × 120 cm) or a small room. The rule of thumb: the volume of your space in m³ should be renewed several times per hour. For a 1 to 1.5 m³ tent, the airflow leaves plenty of margin, even with a carbon filter fitted upstream.

Is it genuinely quiet?

Yes. That is the whole point of the WhisperBlower range: up to 2.5 times quieter than a standard AC motor of comparable output. The aerodynamic redesign of the airflow limits the turbulence that causes noise. For even more silence, it can be paired with an acoustic box or an insulated duct.

Can I connect an activated carbon filter?

Absolutely. The WHSP is optimised for a Ø125 mm carbon filter. Place the filter on the intake side to capture odours before the air passes through the motor, then exhaust the air through ducting. It is the ideal setup for odour-free indoor growing.

Can the speed of this extractor be adjusted?

This is a single-speed version, not natively controllable, designed for simple, reliable operation. If you want to vary the airflow or automate it by temperature, look at a thermo-regulated or multi-speed version of the range, shown below.

The best silence-to-performance balance for your extraction: 460 m³/h driven by a premium ebm-papst motor in a durable housing — the quiet ally of a successful indoor grow.
