Diffuser Size Calculator

The Diffuser Size Calculator is a technical tool designed to assist engineers and HVAC professionals in calculating the appropriate size of diffusers for use in commercial and industrial air distribution systems.

The tool calculates the optimal diffuser size, taking into account factors such as air velocity, throw distance, and air pattern dispersion.

A properly sized diffuser is essential for ensuring that conditioned air is distributed evenly and efficiently throughout a building, which can help to improve indoor air quality and reduce energy costs. This tool can save time and effort for professionals who need to select and install the appropriate diffusers for their HVAC systems.

Instructions:

  1. Select US or Metric units

  2. Select the Diffuser or Grill Type

  3. Enter the velocity criteria, FPM [m/s]

  4. Enter the flow rate, CFM [l/s]

  5. Click the Calculate Button

  6. The Results Table will populate with Diffusers that meet the specified criteria.  There is a link to an example specification sheet located above the table.
