Size ducts by CFM, analyze existing runs, find equivalent sizes, and calculate design friction rate from static pressure — all without creating an account or connecting to the internet. CORE TOOLS — ALL IN ONE APP ▸ Duct Size by Airflow Enter CFM, choose supply/return/exhaust, pick a shape and material, tap "Size" — get a recommended duct size instantly. Switch between friction and velocity methods. Supports round, rectangular, flex, and flat oval ducts with galvanized metal, flex duct, and duct board materials. ▸ Existing Duct Analyzer Got a duct that's already installed? Enter its size to find out how much CFM it can actually handle (Capacity Solver mode), or check what velocity and friction you're getting at a given airflow (Diagnostic mode). This is the reverse-sizing feature field techs have been asking for. ▸ Equivalent Duct Calculator Convert round to rectangular, rectangular to round, round to flat oval — every equivalent size shows cross-sectional area, equivalent diameter, and velocity change. Perfect for material swaps and retrofit work. ▸ Friction Rate Helper Calculate design friction rate the Manual D way: enter external static pressure, subtract component pressure losses (coil, filter, registers, grilles), divide by total equivalent length (supply + return). Built-in TEL calculator: simply tap a straight duct run, select fittings (14 types in the library), add equivalent length — no manual lookup tables needed. One tap to apply your friction rate back to the duct sizer. DESIGNED FOR THE FIELD • Works completely offline — no internet, no account needed • US (IP) and SI (metric) units with one-tap switching • Keyboard input, no cumbersome sliders • Quick-pick buttons for common CFM values and friction rates • Every result shows the formula, assumptions, and warnings • Save jobs, pin favorites, share results as text PRO FEATURES — ONE-TIME PURCHASE Unlock everything with a single purchase. No subscriptions.
