Review: Duct size calculator - Great tool for sizing A/C ductwork - Thanks... Review: Great tool for duct ordering - Exactly what you need in certain occasions ## 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DYB3WHZ7 | | Best Sellers Rank | #77,491 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #105 in HVAC Ducting | | Color | White | | Customer Reviews | 4.8 4.8 out of 5 stars (62) | | Date First Available | February 24, 2025 | | Included Components | Card | | Item model number | ADI-CAL | | Manufacturer | Air Distribution Institute | | Product Dimensions | 11 x 8.5 x 0.1 inches | ## Images ![ADI Ductulator – Duct Size Calculator - Image 1](https://m.media-amazon.com/images/I/71x4qMN1PiL.jpg) ![ADI Ductulator – Duct Size Calculator - Image 2](https://m.media-amazon.com/images/I/81u2ea-uxxL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Duct size calculator *by S***L on May 7, 2026* Great tool for sizing A/C ductwork - Thanks... ### ⭐⭐⭐⭐⭐ Great tool for duct ordering *by J***O on February 28, 2026* Exactly what you need in certain occasions ### ⭐⭐⭐⭐⭐ Installation *by R***M on November 30, 2025* I'm in school for HVAC and you never know which direction you want to go on the field, so I recommend getting it ## Frequently Bought Together - ADI Ductulator – Duct Size Calculator - Air Duct Sizing Calculator - REVISED AND UPDATED!
