Prima Klima Whisperblower EC fan 125 mm - 450 m3/h, EC motor without regulation

Product detailed description

Whisperblower EC 450 m3/h, 125 mm - an economical and maintenance-free base

For a small grow tent, a constant, quiet extract without adjusting the speed is often enough. Whisperblower EC runs fixed at 450 m3/h and uses only 29 W - plug it in, set it up and then leave it alone. The silenced housing and ebm-papst EC motor keep operation economical and quiet.

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. The 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.

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 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 economically and without unnecessary humming. EC is a type of motor, not a way of connecting to anything else.

Key parameters

• Flange diameter: 125 mm
• Max. airflow: 450 m3/h
• Power input: 29 W
• Motor: EC ebm-papst, fixed output (without regulation)
• Max. operating temperature: 50 °C
• 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 assembly, 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 is suitable for

A fixed 450 m3/h and low consumption are aimed at a small tent or a smaller space with a filter. The model has no speed control - if you need it, choose the version with smooth control Whisperblower Beepsblower 450 m3/h or the more powerful Whisperblower EC 800 m3/h.

What to buy with the fan

Add the WHSPEC carbon filter 125 mm for odour extraction. You can find other models in the range in the category Whisperblower silenced fans and fans with EC motor.

Frequently asked questions

Can the output be regulated?

No, this version runs fixed at 450 m3/h. If you want to change the speed, choose a model with smooth control or with a temperature sensor.

Why is its consumption so low?

It uses an economical ebm-papst EC motor with a fixed power input of 29 W. Over an entire season of continuous operation, it saves compared with standard AC motors.

Is it really quiet?

The silenced Whisperblower housing is quieter than the standard range. Because it runs at one speed, the noise level is constant and predictable.
