2024年3月26日 · Generally, the longer the linear diffuser and with more slots, the linear diffuser can supply more air while remaining quiet. Nonetheless, 1200mm 3-slot linear diffusers are very common in commercial buildings while 600mm 2-slot linear diffusers are more common in high-end residential buildings.

Diffusers can be sized based on Noise Criterion (click on the table to the right for ASHRAE Fundamentals-based recommendations based on room type), available static pressure, and/or throw. You can vary the FPM input to hone in on the correct diffuser size for your project.

A model SDS 75 diffuser 4 slots wide and 15 feet long is selected for 1800 cfm of supply air. 1800 “ 15 = 120 cfm per foot. From the performance chart, the NC value is 34. The NC correction for 15 feet of length for supply service is +3. The corrected NC value is 34 + 3 = 37.

These linear slot diffusers feature fully adjustable, aerodynamic pattern controllers fabricated from extruded aluminum, and are available in a large selection of frame styles. The SDS provides the ideal combination of engineering excellence and architectural appeal.

TFE Linear Slot Difusers have been designed to satisfy architectural concepts that require continuous length applications without compromising air distribution performance. A combination of engineering excellence and architectural appeal in a …

2013年12月25日 · If you require 500 cfm you will need 500 cfm/.94 area = 531.9 fpm velocity. Most grill applications consider cfm required for the load and velocity based on noise levels and on how the room is being used.
