Prima Klima Two-Speed Ventilators

Two are more than one, which is why two-speed ventilators are a better basis for reliable and cost-effective grow box ventilation than a device with just one speed setting. 

Switch the speed according to the current needs at the touch of a button on the ventilator casing! 

Two-speed ventilators by PrimaKlima are among the quietest ventilators available on the current market. 

In the case of EC engine ventilators (which we highly recommend to our customers), you can look forward to a premium-quality engine, quiet operation and exceptionally low energy consumption. 

The AC ventilators from this category use a first-rate german MES engine adjusted to the impact-resistant, flame-retardant polyamide (nylon) casing. 

Both ventilator types have maintenance-free ball bearings for reliable and smooth operation. 

The individual models differ in maximum airflow (from 280 m3/h to 950 m3/h) and flange size (from 100mm to 200mm). The bestseller in this category is the PK125-2, with a 125mm connection capable of producing an airflow of 400 m3/h.

Using the included installation console, you can easily and safely attach the ventilator to a wall or ceiling in any position.
