Johnson Controls P170AA-118C Pressure Fan Cycling Control, 1/4 Flare Nut (100/400 psig) — Replacement for P170AA-118

Durable all-steel case and cover provide extended, rugged protection for internal components. The sight-set, calibrated pressure adjustment includes a visible pressure scale and can be adjusted across the full range without removing the cover on NEMA 1 enclosure models. An optional manual-reset lockout delivers a trip-free lockout that cannot be overridden or reset until pressure returns to the specified level. Multiple pressure connection styles are offered to simplify mounting and to adapt the control to field piping and application needs. This unit serves as a replacement for P170AA-118.
