Fan Laws Calculator Change shaft speed or target actual airflow, with optional air-density correction, to estimate flow, pressure, and power at fixed diameter. Fan Power Calculator Use airflow, pressure, and efficiencies to estimate fan shaft power and electrical input. Fan Energy Cost Calculator Combine fan power, operating hours, and electricity rates to estimate energy use and cost. Fan Belt Drive and Pulley Calculator Enter motor speed and pulley diameters to calculate fan speed and compare drive changes. Fan and System Curve Calculator Intersect entered fan data with a system resistance model to estimate the operating airflow and pressure. Series and Parallel Fan Curve Calculator Combine matched fan curves in series or parallel and compare their resulting operating points. Fan Energy Index and Efficiency Grade Calculator Use matched test data and rating inputs to calculate fan energy index or efficiency grade and criterion margins. Fan Balance and Vibration Calculator Compare rotor balance or measured vibration with documented category limits to find tolerance margins. Fan Installation System Effect Calculator Apply documented inlet and outlet geometry to estimate system-effect pressure and supported airflow changes. Fan Tip Speed Calculator Use impeller diameter and shaft RPM to calculate tip speed, or solve for diameter or speed. Fan Heat Gain Calculator Combine shaft power, drive losses, motor location, and airflow to estimate airstream heat gain and temperature rise. Fan Static and Total Pressure Calculator Use signed fan-plane pressures, velocities, and densities to calculate fan static and total pressure rise.
