The industries first “out of box” pneumatic air pump switch for manual fluid feed applications.

This manually operated air switch is designed to operate any air operated double-diaphragm pump up to 1/2” port size or 12 SCFM. The built-in spring return provides “momentary” operation of the air pump. The pump activator turns the air supply off when the button is not fully depressed. The pump activator eliminates the worry of employees becoming distracted, leaving their chemical fill task unmanaged, creating an unsafe environment, or a costly chemical spill. This is the “safe and full proof” alternative to ball valves and on-off air switches that can be left accidentally running by operators.

• #304 stainless steel case with mounting
• Spring return to off state
• Large palm style button
• Color stickers to identify chemical/fluid color
• Optional pressure regulator mounts on side
• Easy to install/use
