The type 604 pressure switch is used as a p ow switch in ventilation ducts for the control of lters and fans, and in primary and secondary control systems for the control of air dampers. The 604 pressure monitoring switches are also ideally suited to protect heating coils from overheating and for monitoring industrial air cooling circuits.
