Prima Klima - Whisperblower PK125WHSP-2 Inline Fan Ø125 mm, 2 speeds, 460 m³/h

Quiet 125 mm inline fan with an ebm-papst AC motor and two speeds: 360 or 460 m³ per hour. Power consumption 63 W, weight 2.73 kg.

What makes the Whisperblower different

Prima Klima developed the Whisperblower together with motor manufacturer ebm-papst. The housing and air guidance were redesigned, so the fan builds more pressure at the same power consumption and makes less noise than earlier Prima Klima fans. That pressure is what counts in a grow room, because a carbon filter and a long duct cost airflow.

The housing is made of impact-resistant, flame-retardant polyamide (nylon). Connection and controls are built into the housing and the cable with plug is attached: ducts on and plug in.

Two speeds with a switch

The housing has a switch for 360 or 460 m³ per hour. You don't need a separate controller. Simple and robust: low for normal air exchange, high for when it gets warm.

Frequently asked questions

What is the difference with the WHSP-3?
The WHSP-3 has three speeds and goes up to 530 m³ per hour. The WHSP-2 has two speeds and a simple switch.

Can I use a carbon filter with it?
Yes, that is what it is made for. Choose a filter with a 125 mm connection that matches the airflow, so the filter doesn't become the limiting factor.
