Pressure regulator DRF active

Product overview
The rectangular DRF active pressure regulators keep a desired pressure constant in a room or supply air/exhaust air duct and are also used to shut off air ducts. Drive and control are carried out with external energy (electrical).

Key benefits

• Highest measuring accuracy
• Reduction of the regulatory effort
• Optimum exploitation of the system’s energy-saving potential by reducing the required pressures

Main features

• With additional volume flow measurement and ActiveControl
• Large control range for difference pressures up to 1000 Pa
• Large measuring range from 1…10 m/s

Performance / ActiveControl advantages

• Highest measuring accuracy of all known systems in the low air velocity range
• Combines extremely short installation lengths with maximum control accuracy in the low air velocity range
• Insensitive to incident flow due to optimized air routing to the measuring element
• Max. 5 % deviation for Vnenn
