ExReg-V300-A is an airflow controller 0-300 Pa designed for use in explosive environments (zones 1, 2, 21, and 22) for controlling airflow in HVAC systems (CAV/VAV). 

Key Features:

• On-site adaptability: The device can be configured directly in the hazardous area without the need for special tools.​

• Integrated PID controller: Ensures precise and stable airflow control.​

• Measurement range: 0–300 Pa, with the option to set the "k-factor" for accurate measurement.​

• Alarm functions: Includes an alarm with adjustable delay for monitoring volumetric flow.​

• Durable construction: Aluminium housing with IP66 protection, optionally available in stainless steel or with a marine environment finish.​

• LCD display: Backlit display provides clear parameter visibility and can be turned off as needed.​

ExReg-V300-A eliminates the need for installing safety barriers or using special cabling, simplifying installation and reducing costs. Its compact dimensions (180 × 107 × 66 mm) and integrated "Ex-e" terminal block facilitate integration into existing systems.

Allows direct connection and control of actuators for HVAC ExMax...-CY or ExMax...-CYF without the need for a safety terminal box ExBox.
