Primaterra Primavent mechanism for automatic control of skylights

Detailed features:

• Type: hydraulic / thermohydraulic cylinder — works through temperature changes of a fluid inside the cylinder.
• Material: construction with aluminum for the frame and metal components for the spring elements.
• Opening force: 7 kg (capable of lifting a skylight with a load of up to 7 kg).
• Activation temperature range: from ~ 17 °C to ~ 25 °C.
• Opening angle: ~ 30° (maximum angle that the mechanism achieves).
• Versatility / model: model PAR3149 is highly mentioned for the Primavent mechanism in catalogs.
• Option: often offered as a universal mechanism , suitable for various models of Primaterra skylights / Greenhouses.
• Double spring design — available in the mechanism, allowing for smooth operation and force when closing back.
• Assembly: fasteners, hook for fixing in the open position, screws and instructions are provided.
• Warranty: 1 year warranty if properly installed and used according to instructions.

Recommendations for use:

• Installation must be careful: secure the mechanism firmly to the frame of the dormer or greenhouse.
• Make sure that the dormer window (the window that will move) does not exceed the permissible load (no more than ~ 7 kg) — a window that is too heavy may not open or break the mechanism.
• The mechanism only functions in a temperature range of ~17-25 °C. At lower temperatures it will not activate, at higher temperatures it will be in the open position.
• A stronger spring can be installed if the skylight is heavier than standard dimensions.
• When installing, ensure that one end of the mechanism can be easily detached — this provides access to the inside of the greenhouse, even if the skylight is closed.
• After installation, monitor the operation for the first few days — make sure the mechanism opens and closes smoothly and without jamming.
• Excessive force or jamming can wear out parts - if you notice any alarming sounds or slowdowns, check the movements and possibly adjust the springs or connections.

Benefits:

The Primaterra Primavent mechanism provides reliable automatic ventilation using a temperature-controlled cylinder. It eliminates the need for electronic controllers, operates without electricity, provides constant ventilation at standard temperature changes, and is universal for different models of dormer windows. With proper installation and maintenance, it provides a comfortable microclimate in the greenhouse.
