Cleveland Controls AFS-298-391 Sensing Switch 319847-401 providing a reliable cyclic dischargeThe Cleveland Controls AFS 298 391 is a high performance air pressure sensing switch designed for precision in commercial HVAC and energy management systems. Engineered as a general purpose differential pressure switch, it monitors positive, negative, or vacuum air pressure with a field adjustable set point range from 0. 05" w. c. to 12. 0" w. c. This unit is factory calibrated to change contacts on increasing pressure at 0. 30" w. c. ( 0. 02" w. c.),
