Low Pressure Pneumatic Actuator
When communicating with EIM for replacement parts or for technical questions, we MUST have
actuator nameplate information, including Job, Serial, and Model numbers. This allows us to check
records of EIM equipment furnished.
When ordering parts, specify repair part by EIM part number and description from drawings
furnished with actuator.
