Air Valve Requirements

Q: I am going to have 5 of these markers working simultaneously. What would be appropriate valving configuration? Do I need to have separate valve for each marker or should I go with one valve with bigger flow for all of them. Please let me know.

A: Yes you need a separate valve for each of them. Please note that the air requirements for air impact markers are referenced through the following link: http://columbiamt.com/CMT-Impact-Marking/Air-Requirements.html
