ANNOUNCEMENT:  Back by popular demand!,  In 2008 Bosch-Rexroth discontinued the Model 2A-2A Controlair after over 50 years of service. The Model 2A-2A had no equal, from its "Z gated" shaft pattern to its legendary imposing presence standing almost 13 inches tall from console flange to the top of the locking lever.   On August 4, 2009 Bosch-Rexroth had the good  sense to announce the re-introduction of the Model 2A-2A Controlair, both Standard (P65775 old WABCO version P50460-0001)10-60 PSI and EMD (P65775-0001 old WABCO version P60318--0002) 30-70 PSI governor input configurations are available. Additional information in Marine Controls Pneumatic catalog.

ANNOUNCEMENT:  In January 2007 Systems Engineering Inc. purchased the Servo Positioner product line from Bosch-Rexroth Corp. Initial production was slow and we apologize to customers that were impacted by the delays that occurred during the transition.

Servo Positioner Availability is now much improved.  Current delivery time is less then 6 weeks for the most common configurations.
