VPVM Large-Area Vent

The large-area vent is an end element for air distribution in air-conditioned and ventilated spaces. Air is brought in at low speed near the floor and removes pollution from the occupancy area to the below ceiling area.

Product Description

Key Features & Benefits

Displacement Airflow
Low-velocity supply at floor level. Uses natural convection to lift heat/pollutants upward.
For High-Load Spaces
Ideal for rooms with high heat loads or dangerous air pollution requiring excellent air quality.
Three Mounting Designs
K: Round, free-standing. S: Wall-mounted (semi-circle). R: Corner-mounted (quarter-circle).
Low ΔT Cooling
Supply air must be only 1–3°C colder than room air for stable, draft-free stratification.
High-Capacity
Handles very large airflow volumes from 500 to 8,100 m³/h for spacious industrial/commercial areas.
