FRC-650 All-In-One combines a filter, regulator and coalescer for shop air into one compact unit. Four 1/4" NPS (M) ball valves with unrestricted air passages, (three regulated plus one unregulated outlet.) Ball valves inclined 45º—avoids kinking of hoses, which increases life span. Robust and durable. Solvent-resistant filter bowl and body is indispensible in the spray area. Solvent- and slip-resistant knob for easy air adjustment. Automatic drains at each stage eliminate water build-up—no need to manually drain.
