Pressure regulator DRE

Product overview
The round DRE pressure regulator maintains a set pressure in a room or in supply/exhaust air ducts and can also be used to shut off air ducts. It is suitable for polluted or chemically contaminated air. Static pressure in the duct or room is measured; the setpoint is compared with the measured value and the control damper is driven until the required setpoint is reached. Activation and control require external electrical power. The housing features push-in ends with lip seals suitable for air ducts to DIN EN 1506 / EN 13180.

Key benefits

• Optimises system energy use by reducing required operating pressures
• Reduces control effort
• Can be combined with high-speed drives
• Optional additional volume flow measurement
• Available with dynamic (DRE) or static (DRE-s) measuring principle

Applications
Use, for example, in conjunction with induction devices. Suitable for maintaining constant pressure levels in rooms or ducts and for airtight shut-off functions.
