Optimum-S Stainless Steel Timer Controlled Condensate Drain – 230 to 6000 psi Optimum-S Stainless Steel Timer Controlled Condensate Drain – 230 to 6000 psi

OPTIMUM– S Drain Assembly consists of a solid-state timer coupled to a solenoid valve and only requires a simple installation procedure. The unit is suitable for ALL compressed air system components (aftercoolers, dryers, filters, pressure vessels and piping), regardless of their size or capacity – simply adjust the interval and discharge times to suit the particular compressed air system requiring stainless
steel valves.
