Key calculations: - Duct calculation Calculate air velocity, friction loss, and equivalent round duct diameter from airflow and duct dimensions. - Duct shapes Run preliminary checks for rectangular, round, and oval duct options. - Airflow and air change calculation Estimate required airflow from room dimensions and air change values, with results in m3/h and L/s. - Grille, louver, and diffuser checks Check face velocity using airflow, dimensions, and free area/effective area ratio. - Unit systems Work with Metric SI or US inch units. - Sharing Share calculation results through the native iOS share sheet. Who it is for: - Mechanical engineers - HVAC design teams - Site and commissioning teams - Technicians - Ventilation and air-conditioning professionals - Students who need preliminary technical checks The app does not include ads, account signup, or subscriptions. Core calculation tools are free. An optional one-time VIP unlock can enable advanced local workflow tools such as duct takeoff, quick sizing, saved records, and professional helper screens. Important note: This app is designed for information and preliminary calculation only. Results are not a substitute for final engineering design, manufacturing, installation, code compliance, or professional judgment. Always verify results with applicable standards, manufacturer data, project specifications, and a qualified engineer. For feedback, suggestions, or bug reports, use the support options inside the app.
