## Overview

The ADI Ductulator is a precision duct sizing calculator developed by the Air Distribution Institute, incorporating university-backed research on flexible duct compression effects. It helps HVAC professionals select the correct duct size to reduce pressure loss caused by typical installation issues such as bends and sags. Featuring both a front calculator and back fitting charts, this tool ensures optimal airflow efficiency and is highly rated by industry users.

## Description

The ADI - Air Distribution Institute, was formed in 1947 to promote the use of fabricated steel duct pipe and fittings for air distribution products. Today the alliance of ADI member companies produce steel duct pipe and fittings designed to efficiently deliver conditioned air in your home and office. ADI sponsors independent third party research to accurately substantiate the superior benefits of Steel Air Distribution Systems. Get your ADI Ductulator today!

## Features

- The ADI Ductulator was created by the Air Distribution Institute based on research conducted by a prestigous university to study the effect of compression in flexible duct on air flow efficiency.
- The data provided on the ADI Ductulator shows research data obtained with flexible duct compressed 4%, 15% and 30% in length. These compressions, and others, were studied because flexible duct is typically not installed “fully stretched” and the resulting installation causes greater pressure loss and is far less efficient in air flow distribution.
- Typical installations are not in a straight line on a flat surface. The kinks, bends, sharp turns and sags of the typical installation increase pressure loss even more than represented by the ADI Ductulators data.
- Using the ADI Ductulator will help you choose the correct size flexible duct to overcome any adverse effects on pressure loss due to the compression and achieve proper CFM and FPM air flow.
- Along with the duct size calculator found on the front of the ADI Ductulator, you’ll find charts with commonly used fittings and other connectors on the back.
