It allows accurate, individual adjustment of airflow for each connected duct, helping you achieve a perfectly balanced and energy-efficient ventilation system.\u003c\/p\u003e\n\u003cp\u003eThis external air restrictor valve connects directly to the distribution box and can be used across the full Air Excellent duct range with the appropriate converters. Airflow settings can be calculated in advance using the Aerflux configurator, while the external adjustment lever allows quick, tool-free fine-tuning without needing to open the distribution box. This makes installation, commissioning, and future maintenance faster and far less fiddly — a small part that saves big headaches.\u003c\/p\u003e\n\u003cp\u003eThanks to its radial design, the AE34C delivers low system pressure loss, reducing fan energy consumption and keeping noise levels to a minimum.
