SF-1020 Probench


The SF-1020 measures and records air flow at OEM engineering accuracy, faster than any other flowbench on the market. It can test up to 240 hp (179 kW) per cylinder at test pressures up to 65” (165 cm) of water. The unique variable flow orifice adjusts flow range between 25 cfm and 1,000 cfm (12 - 472 l/s), based on FlowCom™ input, to fit the valve size or valve lift. The SF-1020 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.

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.
