At 3,600 rpm, the new model produces 2,600 cfm. It also includes an automatic bypass valve to maintain a constant differential pressure. This enables the blower to start from atmosphere, providing effective use over the full pressure range. Depending on the pressure differential, the bypass valve results in a decrease in pumpdown time of 5 percent to more than 50 percent compared to nonbypass blowers with equal capacity. Each of the two positions has an adjustable hardened stop for location repeatability and can be fitted with a self-adjusting shock absorber to reduce tooling fatigue.
Position is achieved with the use of standard four-way valves.
