Round variable pressure controller with airflow measurement

Galvanised round pressure control damper with airflow measurement, equipped with an electronic actuator and plastic static pressure measuring probe. Additionally, it is equipped with a specific aluminum differential pressure sensor and measuring transmitter to measure the actual airflow rate. The damper is used to regulate constant or variable static pressure in supply or exhaust ducts. The actuator and measurement transmitter are equipped with hybrid control as standard: analogue 0(2)-10VDC and/or Modbus. The oval damper blade is equipped with an airtight gasket and maintenance-free bearings. The casing airtightness meets class C according to EN1751, and damper blade air leakage meets class 2 according to EN1751. Available without insulation (PVRS) and with insulation (PVRD). External circular duct silencers are available as an option.
