PCD Supply Diffusers, are recommended for heating, ventilating and cooling, and for conditions requiring on-the-job adjustment of air diffusion patterns.

DEFLECTOR — Square necks having directional deflectors that are adjustable for 4, 3, 2, or I-way horizontal diffusion patterns.

Both type diffusers have high diffusion induction rates resulting in rapid temperature and velocity equalization of the mixed air mass well above the zone of occupancy.

The horizontal performance of these full-flow and / or directional deflectors ensure confident use of cooling differentials of 25°F and greater, at predicted low air motion (35 fpm) in the zone of occupancy.

型號PCD沖吼金屬網頁風口 PCD沖吼金屬網頁風口適用於空調及抽風系統，後置活動分風片可調節一至四路之氣流活動而不會改變風口表面之外型，而此型號之風口特點是氣流流動較慢，令環境更加舒適。
