The SF-450 is one of the most versatile flowbenches on the market today. It flows 580 cfm at 25" of water, enabling users to evaluate their test results in ultra high resolution so the smallest changes in flow are visible. The SF-450 comes standard with our FlowCom™ digital airflow measurement system for accurate, repeatable and fast testing. FlowCom™ ensures accurate digital airflow measurement and control by automatically measuring test pressure and temperature; then presenting corrected flow data on the easy-to-read, precision display. This saves users considerable time when compared with standard manometer type benches that require users to make calculations to achieve corrected flow numbers. The included automatic motor controller maintains constant test pressure without the use of knobs and valves and it also helps extend motor life by reducing heat generated during operation. Reduced heat means that operators can run the SF-450 for longer durations than benches lacking the motor control feature.
