PRIMA KLIMA Whisperblower-3 Fan 300/420/530 m3/h, 125 mm, 3 speeds (PK125WHSP-3)

Product detailed description

Whisperblower-3 300/420/530 m3/h, 125 mm - three speeds, finer adjustment

Do you need a silenced 125 mm fan with slightly finer power adjustment? Whisperblower-3 offers three fixed speeds - 300, 420 and 530 m3/h - so you can adjust airflow and noise to the cultivation stage and time of day more precisely than with the two-speed version. All this with a silenced Whisperblower body and an affordable AC motor.

Why Whisperblower is quieter

Whisperblower is not a standard fan with an additional silencer. It is a silenced design with a redesigned aerodynamics of the body and impeller, developed in cooperation with ebm-papst. Air inside flows like on a roller coaster - the new channel geometry creates higher pressure and airflow at the same energy efficiency while also reducing noise compared with the standard range of the same diameter.

Key parameters

• Flange diameter: 125 mm
• Speeds: 300 / 420 / 530 m3/h
• Power input: 57 W
• Motor: AC, three-speed switch
• Power supply: 230 V
• Dimensions: 315 x 309 mm

Matching with filter and ducting

Always choose the same diameter for the fan, filter flange and ducting - in this model 125 mm. A carbon filter increases the resistance of the system, so size the fan with a reserve above the needs of the growing space and match the filter and ducting to the same 125 mm diameter. Mismatched diameters otherwise add unnecessary resistance, reduce performance and increase noise.

For which space

The three speeds will be appreciated by a grower who wants to adjust extraction according to the stage and season. When two speeds are enough, the cheaper Whisperblower 2-speed is available; for smooth EC control, choose the Whisperblower EC 800 m3/h.

Frequently asked questions

Why three speeds instead of two?

Three levels give a finer step between quiet and full operation. It is easier to find a compromise between airflow and noise according to the cultivation stage.

How are the speeds switched?

With a simple switch directly on the supply, without an external controller. You can use the lowest level at night and for saving.

Is it really quieter?

Yes, thanks to the silenced construction of the body and impeller. At the same diameter, it is quieter than a standard fan.
