Ventilation breather MAGNAPLAST BREATHER INTERNAL D110 — internal duct breather, ø110 mm

MAGNAPLAST BREATHER INTERNAL D110 is an internal duct breather designed for ventilation systems with a nominal diameter of 110 mm. The component enables air exchange and pressure equalization inside ductwork and extraction channels, supporting stable airflow in residential and light commercial HVAC installations. Its compact round shape is intended for integration into circular ducts and fittings where ventilation balance or controlled bypass is required.

Advantages

The breather provides reliable pressure equalization and helps prevent backdrafts and stagnant zones within duct networks. Its Ø110 mm round format allows straightforward connection to standard circular ducts and reduces the need for adapters. The compact, simple construction supports easy installation and low maintenance while remaining suitable for use in systems where discreet internal components are preferred.

Suitable for

• Residential ventilation and kitchen or bathroom extraction systems
• Light commercial ventilation ducts and air handling units
• Balancing airflow between connected duct branches
• Systems requiring internal pressure equalization or controlled bypass

Key specifications

• Nominal diameter: 110 mm (round duct connection)
• Application: internal duct breather for ventilation and extraction
• Form factor: compact circular component for in-duct installation
• Intended environments: residential and light commercial HVAC systems
• Functionality: air exchange and pressure equalization within ductwork

How to use

Install the MAGNAPLAST internal breather directly into a 110 mm round duct or appropriate fitting at the location where airflow equalization or a bypass is required. Ensure the breather is oriented and secured according to the duct layout so that it does not obstruct primary airflow. Check that connections are airtight where necessary and that the component is accessible for periodic inspection. Integration may involve cutting the duct, inserting the breather, and sealing the joint with suitable duct tape or sealant to maintain system performance.

Usage recommendations

Use the breather in systems with matching 110 mm ducting and within the manufacturer’s recommended application scope. Verify compatibility with the existing ventilation design to avoid undue pressure loss. For best results, combine installation with a visual inspection of the duct system and, if required, a measurement of airflow to confirm the breather achieves the intended balance.
