Zonex Systems STRDBP20 Bypass Damper with Integrated Static Pressure Control, Round, 20 Diameter

Product Description

The Zonex Systems STRDBP20 is a round bypass damper designed to control static pressure in zoned HVAC systems. This heavy-duty unit reduces noise from excessive air velocity. It works to keep static pressure steady as zone dampers modify air flow. The STRDBP20 is suitable for systems with continuous fan operation. The adjustable controller maintains static pressure within a range of zero point one five to zero point ninety-five inches of water column. The damper features durable construction with twenty-four gauge steel for low leakage.

• Integrates static pressure control for HVAC zoned systems
• Durable twenty-four gauge steel construction
• Adjustable controller for static pressure maintenance
