it ensures fail-safe operation by returning the damper to its original position during power interruptions

failing to switch as commanded by the thermostat

Integrated Time Delay: Reduces short-cycling by allowing momentary pressure fluctuations without disconnecting the compressor contactor

Built with a balanced port design and an integrated check valve assembly

It provides the central control board with precise thermistor data from the lower section of the tank to manage thermal stacking and prevent high-limit tripping

Bell & Gossett A91555 Baffle 321042-401 it ensures fail-safe operation byThe Bell & Gossett A91555 Baffle is a critical replacement component engineered specifically for B&G Rolairtrol air separators. Designed as a direct internal part for the Rolairtrol air control system, this baffle is essential for maintaining the centrifugal flow pattern required to separate air from the system fluid in hydronic heating and cooling systems. Constructed from durable materials to withstand high velocity flow and closed loop system
