ERPC, Constant air flow regulators for circular duct
ERPC Constant air flow regulators for circular duct
Description
Flow rate regulators for circular ducts on systems with constant flow rate.
Automatic mechanical operation, without auxiliary energy to keep the air flow rate constant within a differential pressure range.
Use
In all ventilation systems to keep the air flow rate constant, regardless of the pressure system used and of the pressure variations within the permissible range.
Characteristics
Material: galvanised steel.
Finish: galvanised.
Operating temperature: -20° +100°C.
Installation: on circular duct.
Notes
Air flow rate within a differential pressure range between 40 and 600 Pa (1000 for some models).
The accuracy of the air flow is ± 5-10%, depending on the speed and conditions of use.
The regulators can be calibrated on site directly in the finished system by means of the regulating device.
Maintenance free.
