Aprilaire 6116 16″ Round Mechanical Bypass Damper

Description

Aprilaire 6116 Mechanical Bypass Damper Overview

The Aprilaire 6116 is a 16-inch round mechanical bypass damper engineered to maintain proper static pressure and balanced airflow in residential and light commercial HVAC zoning systems. By automatically diverting excess conditioned air back to the return side of the system when zones close, this bypass damper helps protect the blower and heat exchanger from the damaging effects of excessive static pressure buildup.

Key Features

• 16-inch round duct configuration for compatibility with standard residential and light commercial duct systems
• Mechanical (non-electric) operation — no wiring or control signal required for reliable, passive pressure relief
• Automatically opens in response to increased static pressure when zone dampers close
• Helps protect HVAC equipment from over-pressurization and premature wear
• Durable construction designed for long-term, low-maintenance service
• Compatible with Aprilaire zoning systems and other multi-zone HVAC applications

Application

The Aprilaire 6116 bypass damper is ideal for use in multi-zone forced-air HVAC systems where pressure imbalances can occur as individual zone dampers open and close. Installing a mechanical bypass damper between the supply and return plenums ensures that airflow is never fully restricted, protecting the air handler and extending equipment life.
