Bradford White 415-46037-01 1.40" Exhaust Pressure Switch

Bradford White 415-46037-01 Exhaust Pressure Switch 1.40” is a safety part that is used in HVAC systems, particularly in gas-fired water heaters. It measures the pressure of the exhaust gases to check the right amount of venting. If the exhaust flow is blocked or low, the switch senses the pressure difference and turns off the water heater to avoid the production of hazardous carbon monoxide. This increases safety, optimizes the operation by guaranteeing efficient combustion, and reduces maintenance expenses due to possible harm from incorrect venting.
