Neptronic SPC Static Pressure Controller monitors duct pressure and regulates airflow within HVAC systems to maintain stable operating conditions. By measuring pressure differentials and modulating control outputs, the controller ensures consistent airflow distribution throughout duct networks.
This controller is commonly used in variable air volume (VAV) systems, where maintaining constant duct pressure is critical for proper airflow balancing. When pressure exceeds the configured setpoint, the controller modulates dampers or fan speeds to restore stable airflow conditions.
Designed for integration with building automation systems, the controller provides reliable airflow monitoring and control for commercial and institutional HVAC installations.

Accurate monitoring and control across low differential pressure ranges.

Selectable voltage or current outputs for flexible BAS integration.

Setpoint, dead band, and response speed tuning for optimized performance.

LCD display and analog output for continuous pressure visibility.

Compact footprint and enclosure options for diverse mounting conditions.

Optimizes VAV, bypass damper, and pressurization control to reduce energy consumption.
LCD-equipped controller with adjustable setpoint and dead band, selectable output signal, direct or reverse action outputs, and real-time pressure display. Suitable for bypass damper actuators, VFD control, laboratory, and stairwell pressurization.
