Swirl Diffuser for Gym, Warehouse & Large Ceiling Spaces

Swirl Diffusers for High-Ceiling Spaces: Draft-Free Air Distribution

PRODUCT DESCRIPTION:

Solves cold-draft and hot- stratification problems in rooms with ceiling heights from 4 m to 15 m, where ordinary grilles fail.
High induction ratio of 30–50× primary airflow means supply air spreads evenly along the ceiling instead of dumping straight down.
Field-proven in gymnasiums, supermarkets, warehouses, airport terminals, exhibition halls, shopping malls and underground stations.
Low noise swirl design keeps NC level within comfort range even at high supply-air Delta-T and high airflow rates.
Engineers assist with CFM calculation, face size selection and throw distance based on your room load and duct layout.

Product Details

In high-ceiling buildings, conventional ceiling grilles dump cold supply air straight down, creating drafts at floor level and a stagnant, hot layer near the ceiling. A swirl diffuser solves this by spinning the air radially outward in a wide horizontal vortex.

The vortex entrains 30 to 50 times its own volume of room air, rapidly tempering the supply air and spreading it evenly across the ceiling before it slowly descends. The result is a comfortable, draft-free occupied zone with stable vertical temperature gradient, even in rooms 6 to 15 meters high.

Product Data

This makes aluminum swirl diffusers the preferred terminal device for gymnasiums and sports halls, supermarkets and hypermarkets, warehouses and logistics centers, airport terminals and railway stations, exhibition halls, shopping mall atriums, underground parking and large workshop spaces. Compared with jet nozzles or linear slot diffusers, swirl diffusers deliver quieter operation, simpler installation and lower first cost while still handling high airflow rates.
