United Electric J21K-140 Pressure Switch 318172-701 the Siemens Building Technology 184-113

the Siemens Building Technology 184-113 Tee Restrictor is the critical component for maintaining precise branch pressure in one-pipe pneumatic circuits

Restores Pressure Balance: Maintains the internal trap seal necessary for the high-pressure switch to stay closed during operation

but if the leak continues

while the 25 µm internal filter ensures minimal pressure drop with high dirt retention

A: Bent or damaged grilles can restrict airflow and expose fan blades to debris or accidental damage

United Electric J21K-140 Pressure Switch 318172-701 the Siemens Building Technology 184-113The United Electric J21K 140 Pressure Switch is a high sensitivity differential pressure switch engineered for precise monitoring in demanding HVAC and industrial environments. This unit utilizes opposing brass bellows to accurately detect the pressure drop across filters, coils, or heat exchangers. With an adjustable range of 0 to 6 PSID and a tight deadband of 0. 1 to 0. 4 PSI, it provides the low end resolution required for airflow proving and high
