PK Extraction Fan Silenced WHSP-L 1-Speed, 480m3/h

Quiet 125 mm duct fan delivering up to 480 m³/h for continuous extraction

The PK Extraction Fan Silenced WHSP-L 1-Speed, 480m3/h is a single-speed Prima Klima WhisperBlower designed for extraction systems with 125 mm ducting. With a maximum airflow of 480 m³/h, it is suitable for continuously removing air from grow tents and indoor growing areas. Its airflow-optimised housing combines a compact format with a design focused on pressure performance and reduced operating noise.

Single-speed operation with 480 m³/h airflow

The PK125WHSP-L uses one fixed speed setting and provides a maximum airflow of 480 m³/h. This makes it a straightforward option when you do not require selectable speed stages directly on the fan. Its 125 mm connection can be incorporated into appropriately sized ventilation systems. Other airflow capacities and configurations are available in the range of AC duct fans.

Optimised airflow for extraction systems

Prima Klima developed the WhisperBlower series around an aerodynamically optimised housing and airflow path. The design is intended to generate greater pressure than conventional designs at comparable energy consumption while producing less noise. This is useful where additional resistance is introduced into an extraction system. For odour control, the fan can be combined with a suitably rated carbon filter. The filter capacity and connection diameter should always be matched to the ventilation system.

Durable housing and proven AC drive

The fitted ebm-papst AC motor has a power consumption of 52 W. Its housing is manufactured from impact-resistant, durable polyamide, also known as nylon, and the connection system is integrated into the housing. Measuring 315 × 309 mm and weighing 2.70 kg, the WhisperBlower remains compact enough for installation in many grow tents and dedicated extraction setups.
