Multileaf dampers & weather resistant louvres
Multileaf dampers can be used in a ventilation system to adjust volume flows or pressures. They are used to throttle the air flow and enable pressure equalization, e.g. of different ducts. When a system is at a standstill, they are suitable for shutting off and closing the air duct to the outside. In combination with a weather protection grille, the uncontrolled entry of moisture is prevented. Designed as pressure relief dampers, multileaf dampers allow the air duct to open automatically and then close.
Wildeboer offers different types of multileaf dampers. Whether in large sizes, with special requirements in terms of temperature conditions or drive selection, or combined ex works with a weather protection grille, we offer the right product for your application.

Frequently asked questions about multileaf dampers & weather resistant louvres
A multileaf damper is a component in ventilation systems that can be used to open, close or restrict airflows. It consists of several slats arranged in parallel, which are adjusted together to alter the free flow cross-section. Multileaf dampers are frequently used for shutoff, air volume adjustment or control in supply and extract air ducts. The choice of damper depends on the installation situation, air flow rate, pressure drop and the requirements for airtightness and controllability.
A weather resistant louvres is a component for fresh air or exhaust air openings in ventilation systems. It protects the air duct from the direct ingress of rain, leaves, coarse debris and small animals, whilst allowing air to enter or exit. When selecting a grille, factors such as air flow rate, pressure drop, acoustic requirements and the installation situation on the façade must be taken into account.
When installing weather resistant louvres, care must be taken to ensure they are fitted correctly, securely and in a weather-resistant manner into the external wall or façade. The slats must be aligned in such a way that rainwater is kept out and drained away as effectively as possible. It is also important to ensure a sufficient clear cross-section, appropriate connection dimensions, and to take into account air flow rate, pressure loss and noise levels. The grille should remain easily accessible so that dirt, leaves or foreign objects can be removed as required. In addition, the structural conditions, the façade connection and the specific installation situation must be taken into account during the planning stage.
