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.

Three speeds with a rotary knob

The housing has a rotary knob to choose between 300, 420 and 530 m³ per hour. You don't need a separate controller. On low it keeps a small tent quietly at temperature, the highest speed is there for warm days or a full room.

Frequently asked questions

What is the difference with the WHSP-2?
The WHSP-2 has two speeds (360 and 460 m³ per hour). The WHSP-3 has three and goes up to 530 m³ per hour.

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.
