Prima Klima Whisperblower ECblue 125 mm - 800 m3/h, EC motor

Product detailed description

Whisperblower ECblue 125 mm - ready for a digital controller

Are you looking for a silenced 125 mm fan that can later be connected to smart climate control? Whisperblower ECblue has an ebm-papst EC motor, an airflow of up to 800 m3/h and also an RJ45 connector, which lets you connect it to a digital controller with a standard LAN cable. The silenced housing keeps operation quiet even under filter load.

Why Whisperblower is quieter

Whisperblower is not a standard fan with an additional silencer. It is a silenced design with a redesigned housing and impeller aerodynamics, developed in cooperation with ebm-papst. Air flows inside 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.

What the ebm-papst EC motor does

The EC motor is an electronically commutated motor with electronics integrated directly into the housing. It stands out for low power consumption, quiet operation and smooth speed control. Unlike cheap phase control on AC motors, energy is not lost on the way to the motor, so the fan runs efficiently and without unnecessary humming. EC is a type of motor, not a way of connecting it to something else.

Key parameters

• Flange diameter: 125 mm
• Max. airflow: 800 m3/h
• Power input: 170 W
• Motor: EC ebm-papst, RJ45 connector
• Power control: 0-100 %
• Max. operating temperature: 50 °C

Matching with the 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.

What space it suits

The model covers a medium grow room with a filter on 125 mm ducting. The ECblue version is suitable where you plan to use the PK-DGTL-THC controller and speed control according to temperature and humidity. Without an external controller, the Whisperblower EC with smooth control on the housing version will serve you well.

What to buy with the fan

Match the WHSPEC 125 mm carbon filter and for full automation the PK-DGTL-THC controller with RJ45. Other sizes and variants are in the fans with EC motor category.

Frequently asked questions

What do ECblue and the RJ45 connector mean?

ECblue is an EC fan with an RJ45 connector. With a standard LAN cable, you connect it to the PK-DGTL-THC digital controller, which adjusts the speed according to temperature and humidity.

Does it work without a controller?

Yes, it runs on its own too. Add a controller when you want the speed to change automatically - otherwise the model runs at the set output.

How is it better than the AC range?

The EC motor has lower power consumption, smooth control and quieter operation. The silenced Whisperblower housing also adds higher pressure with lower noise.
