PK Extraction Fan Silenced WHSP EC & Temp. Controlled, 800m3/h

Prima Klima Silenced WHSP EC – quiet extraction with automatic temperature control

The Prima Klima Extraction Fan Silenced WHSP EC & Temp. Controlled, 800m3/h is a temperature-controlled EC inline fan designed for powerful extraction systems in grow tents and indoor grow rooms. The PK125WHSP-ECTC combines a 125 mm connection, airflow of up to 800 m³/h and an ebm-papst EC motor. It is particularly useful when you want extraction to respond automatically to changing temperatures while retaining direct control over minimum and maximum fan speed. You can compare it with other EC duct fans for indoor growing.

Temperature-responsive fan speed

Three separate controls allow you to set the target temperature, minimum speed and maximum speed. The temperature setpoint can be selected between 20 and 30 °C. When the measured temperature exceeds this value, fan speed rises automatically towards the selected maximum output. Once the temperature drops below the target again, the fan returns to the chosen minimum setting. The minimum-speed percentage is calculated in relation to the selected maximum speed, allowing you to maintain continuous background extraction while keeping additional ventilation capacity available when temperatures rise.

EC motor and optimised WhisperBlower housing

Prima Klima uses an electronically commutated ebm-papst motor that consumes power according to its operating speed. The aerodynamically optimised WhisperBlower housing is designed to guide airflow efficiently, generate useful pressure and reduce operating noise compared with conventional housing designs. Its outer housing is made from durable, impact-resistant polyamide.

Designed for 125 mm extraction systems

The 125 mm flange allows the fan to be incorporated into suitably sized ducting systems. For odour filtration, it can be combined with an appropriately rated activated carbon filter. The filter, ducting and other components should be selected according to both the 125 mm connection size and the airflow requirements of the complete system. According to the manufacturer, the fan is intended for indoor ventilation installations.
