I have installed two Air Logic low pressure systems, one for FB, the other for presoak. This was a refit of an old system for a 7 bay SS. Been 3 years for the FB and 4 years for the PS. I haven’t had to replace one component on either unit. They are all common parts, non proprietary. Very compact.
Great value. No complaints.
Also my old existing system did not have separate air and chemical lines to the boom. I just tapped into the existing 3/8 braided poly lines in the mechanical room. So I have a single 3/8 line to the booms with a foam generator just before the boom. Good foam and show at gun and brush. Hope this helps.
