Constant volume dampers WRM
WRM air volume controllers are designed for use in air conditioning and ventilation systems and can be installed both horizontally and vertically in supply and exhaust ducts. These controllers are made of galvanized sheet steel and are equipped with a centrally supported control damper for precise airflow regulation.
Introduction
WRM controllers are independent mechanical units that provide constant airflow regulation without the need for a power source. They are ideal for systems that require a constant flow rate, regardless of pressure variations within the system.
Features
- Robust Construction: Made from galvanized sheet steel for durability and reliability.
- Flexible Mounting Options: Can be installed both horizontally and vertically.
- Precise Control: Equipped with a control unit featuring a rotating pointer and scale for accurate flow settings.
- Wide Range: Control range of at least 5 times the minimum airflow, with adjustable settings that can be locked in place.
