VASM Whirling Anemostat with Adjustable Blades

A heavy-duty terminal HVAC element designed to distribute large air volumes with high temperature differential. Its adjustable blades allow airflow angle modulation from horizontal to vertical, ensuring intensive air mixing in high industrial and commercial spaces.

Product Description

Key Features & Benefits

Adjustable Whirling Flow
Manually or automatically adjust blade angle to control air outflow direction (vertical/diagonal/horizontal).
High ΔT Performance
Specifically designed for air with high temperature differences (-10°C to +15°C ΔT).
Industrial Capacity
Handles very high airflow volumes from 350 to 2,400 m³/h for large halls.
Actuator Compatibility
Ready for integration with BELIMO servo actuators (24V/230V) for automated, signalable control.
High Ceiling Application
Designed for spaces with installation heights over 3.8 meters (warehouses, atriums).
Mode Optimization
Horizontal flow for cooling, vertical for heating, diagonal for mixing, maximizing efficiency.
