Prima Klima Fan 390/760 m3/h, 150 mm, 2-speed (PK150-2)

Product detailed description

Prima Klima PK150-2 390/760 m3/h, 150 mm - two speeds, quiet operation

Are you looking for a 150 mm extract fan with the option to switch output while staying quiet? PK150-2 offers two speeds - 390 and 760 m3/h - and an impeller with backward-curved blades, which delivers up to 15% higher airflow than standard fans. The lower speed is exceptionally quiet.

Basic AC range - why it is more affordable

The model belongs to Prima Klima's basic AC range. It uses a classic AC motor with an impeller with backward-curved blades and is more affordable than EC motor variants. It does not have smooth electronic control - the output runs at a fixed setting, or it switches between fixed speeds. For a lower price, you get a reliable duct fan with quiet operation and low energy consumption.

Key parameters

• Flange diameter: 150 mm
• Speeds: 390 m3/h and 760 m3/h
• Motor: AC MES, two-speed switch
• Impeller: backward-curved blades
• Ball bearings for smooth operation
• Installation: horizontal and vertical

Matching with filter and ducting

Always choose the same diameter for the fan, filter flange and ducting - in this model, 150 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 150 mm diameter. Otherwise, mismatched diameters add unnecessary resistance, reduce performance and increase noise.

For which space

At the higher speed, it covers a medium grow room with a filter. If one speed is enough, choose PK150-L 760 m3/h or the more economical PK150-A 600 m3/h.

What to buy with the fan

For odour extraction, fit a Prima Klima carbon filter 150 mm. For smooth control, an external speed controller is suitable. You can find the range in the two-speed fans category.

Frequently asked questions

What is the difference between the speeds?

The lower 390 m3/h is quieter and more economical, while the higher 760 m3/h provides full extraction. You switch between them according to need and time of day.

What does 15% higher airflow mean?

The impeller with backward-curved blades moves more air than conventional fans at comparable consumption.

Can it be controlled smoothly?

Not directly, it switches between two speeds. You can get variable speed with an external speed controller.
