Siemens Building Technology 184-113 Tee Restrictor or a failing run capacitorFor veteran technicians managing legacy air systems, the Siemens Building Technology 184 113 Tee Restrictor is the critical component for maintaining precise branch pressure in one pipe pneumatic circuits. Engineered as a direct replacement for the 21 039, this 20 SCIM pneumatic restrictor ensures that bleed type controllers, such as one pipe thermostats and transmitters, function with the necessary backpressure for accurate modulation.
