Optimized Condensate Flow: Engineered with a specific internal pitch to promote efficient condensate drainage and minimize standing water

Exceeding this pressure can damage the internal diaphragm and lead to component failure

Durable Construction: Features TEAO (Totally Enclosed Air Over) enclosure to protect internal windings from moisture and debris in harsh outdoor environments

it is recommended to also inspect the 383-500-250 insulation and ignitor kits separately

For specific chemical compatibility with the brass body and Buna-N O-ring

Cleveland Controls NS2-1239-00 Pressure Switch L99H008 Optimized Condensate Flow: Engineered withThe Cleveland Controls NS2 1239 00 is an industrial grade air flow pressure sensing switch specifically designed to monitor positive, negative, or differential air pressure in HVAC systems. This fixed set point pressure switch is factory calibrated at . 70" w. c. (inches water column), ensuring high accuracy for critical safety applications such as proving fan flow or detecting filter blockage. Built with a glass filled polycarbonate housing and a
