Quiet Operation: Soft-start and variable speed capabilities minimize 'duct thumping' and ambient operational noise
the Siemens Building Technology 184-113 Tee Restrictor is the critical component for maintaining precise branch pressure in one-pipe pneumatic circuits
while the 25 µm internal filter ensures minimal pressure drop with high dirt retention
Restores Pressure Balance: Maintains the internal trap seal necessary for the high-pressure switch to stay closed during operation
ensuring that your V5011 or V5013 valve assemblies operate within their specified 2-7 PSI range without the need for field modifications
United Electric J21K-140 Pressure Switch 318172-701 Quiet Operation: Soft-start and variableThe 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
