SF-750 Flowbench


The SF-750 is the new standard in digital flow testing, with more capacity than its predecessor, the SF-600, and increased accuracy with digital measurements. It flows 660 cfm at 25” of water. The SF-750 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-750 for longer durations than benches lacking the motor control feature.

RTS Tooling Pressure Differential Valves

RTS Tooling’s Pressure Differential (PD) Valves measure pressure differentials in the valve flow area without obstructing the flow path of the air being tested. This allows users to obtain accurate, repeatable results along with additional information not typically compiled in air flow tests using standard mapping technology. The included PD Valve software compiles and stores all the data from tests numerically. The program also graphically displays pressure differentials in color, as well as, velocity and radial flow. As a result, the PD Valve Software is able to identify specific problem areas in the test subject and provide valuable data for improvements.
