PL

Description

The PL range of commercial dampers is designed for airflow control, balancing, and isolation in HVAC ventilation systems for commercial buildings. Suitable for large sizes up to 2000 × 1950 mm in a single module, it ensures excellent mechanical strength and precise airflow management throughout HVAC networks.

Manufactured in France and available in several performance classes, the PL range meets airflow control, frost protection, and isolation requirements with various leakage classes in accordance with EN 1751. Thanks to its reinforced construction in galvanized steel, stainless steel, or aluminium, it is particularly well suited to demanding commercial applications requiring pressure resistance and long-term reliability.

Its modular design also allows for numerous configurations, including stainless steel, galvanized steel, or aluminium construction, high-temperature versions up to +200°C, multi-module assemblies, and circular adaptations.

The PL damper can be installed in air handling units (AHUs), HVAC ductwork, and large-scale ventilation systems. It is available in both manual and motorized versions.
