Our wide experience makes us specialists in the design and manufacture of dampers, which is an essential part of any ventilation and smoke extraction system.

They are applied to road, Underground, railway tunnels and to all kinds of underground facilities.

Depending on the characteristics of each project, we have developed two types of dampers:

  • Adjustable dampers. These are for ventilation systems that require a controlled air flow. They consist of a system of slats that make it possible to adjust the degree of ventilation.
  • Open/Close dampers. These are used in systems that require the complete opening or closing of air flow. When open, they allow air flow and, when closed, the air current is interrupted.

Depending on their position, dampers can be attached directly to the fan panel or to any other support by using a special bracket.

Dampers can be installed vertically or horizontally and, based on the requirements of each project, they are available with the following finishes:

  • Stainless steel
  • Galvanised steel
  • Painted steel

In addition, we have developed a wide range of accessories for dampers:

  • Actuators: Robust, reliable and accurate. Specifically designed to ensure their correct operation for years. Depending on our customers’ needs, they may be electric, pneumatic or electro-hydraulic, with a control cabinet integrated into the ventilation system.
  • Housing: This provides perfect thermal protection, even in the most adverse conditions.
  • Guards: Metallic covers or structures for their external protection, adapted to the technical specifications of each particular case.

Our dampers are delivered on site in a perfectly identifiable format, including all relevant information related to the project: position, materials, weights…

In addition, Zitrón has designed a packaging system that facilitates their transport and handling on site in a completely safe manner.
