Precise Filtration: The porous molded core effectively captures solid contaminants including carbon and metallic particles

For variable frequency drive (VFD) applications

Flooding is often caused by a fouled valve seat or debris stuck in the assembly

it efficiently handles pressure ranges from 0-100 PSI

Lochinvar & A.O. Smith 100109934 Switch 321894-708 Precise Filtration: The porous moldedThe Lochinvar & A. O. Smith 100109934 Switch is a critical safety component engineered for high efficiency condensing boilers and commercial water heaters. Functioning as a blocked outlet switch, this normally closed (NC) pressure sensor is calibrated to 2. 6" WC to monitor exhaust backpressure. If the venting system becomes obstructed by debris, ice, or mechanical failure, the 100109934 triggers an immediate system lockout to prevent the hazardous
