PRIMA KLIMA WHISPERBLOWER Fan 360/460 m3/h, 125 mm, 2-speed (PK125WHSP-2)

Product detailed description

Whisperblower 360/460 m3/h, 125 mm - two speeds for day and night

Do you want a silenced 125 mm fan, but do not need smooth EC control? Whisperblower 2-speed lets you switch between 360 and 460 m3/h with a switch - higher extraction by day, quieter mode at night. You get a quieter silenced Whisperblower unit at an affordable price in the AC range.

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 housing 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 and at the same time reduces noise compared with the standard range of the same diameter.

Key parameters

• Flange diameter: 125 mm
• Speeds: 360 m3/h and 460 m3/h
• Power input: 63 W
• Motor: AC, two-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. Otherwise, mismatched diameters add unnecessary resistance, reduce performance and increase noise.

For what space

The two speeds are suitable for a small to medium tent, where you want to reduce output at night. If one speed is enough at a lower price, there is the Whisperblower 480 m3/h 1-speed; if you want three levels, choose the Whisperblower-3 with three speeds.

What to buy with the fan

For odour extraction, fit the WHSPEC 125 mm carbon filter. You can find the full range in the two-speed fans category.

Frequently asked questions

What are the two speeds for?

You use the higher speed during the day or in warm conditions, the lower one at night for quietness and savings. You switch them with one switch, without an external controller.

Is it quieter than a standard fan?

Yes, the Whisperblower housing is silenced, so it runs more quietly than the standard range at the same diameter - even at the higher speed.

Is a power cable included in the package?

Check the variant description; some Prima Klima fans are supplied without a cable, which must be purchased separately.
