T-connector MAGNAPLAST MAGNAPLAST TROJNIK Ultra dBEA 75/75/45 (MPN 146520)

MAGNAPLAST TROJNIK Ultra dBEA 75/75/45 is a T-connector engineered for duct and pipe systems where a main run divides into a smaller branch. The connector provides a fixed three-way junction with diameters suited for 75 mm, 75 mm and 45 mm branches. It is manufactured from materials compatible with ventilation and drainage installations and is intended for use in professional HVAC and pipe routing projects where a durable, dimensionally consistent split is required.

Advantages

The T-connector offers a precise fit for 75/75/45 duct layouts, ensuring stable mechanical connection and consistent airflow or liquid routing between the main and branch lines. Its molded geometry reduces the need for additional sealing work and helps maintain alignment during installation. The component is produced to tolerances appropriate for modular duct systems, which simplifies integration with standard 75 mm and 45 mm duct components.

Suitable for

• HVAC ductwork installations that require a 75/75/45 three-way split
• Ventilation systems in residential and light-commercial buildings
• Drainage or waste air routing where a main line splits to a smaller branch
• Professional pipe routing and retrofit projects using standard 75 mm and 45 mm fittings

When it may not be suitable

This T-connector is not intended for use with non-standard duct sizes or systems that require flexible, adjustable branching angles. It may not be suitable for applications that demand specialized sealing or pressure ratings beyond typical ventilation or gravity drainage systems.

Key specifications

• Connection layout: three-way T-connector with two equal larger outlets and one smaller outlet
• Outlet diameters: two outlets at 75 mm and one outlet at 45 mm
• Intended applications: ventilation and drainage routing for air or gravity-flow fluids
• Material type: molded component compatible with standard duct installations
• Design: fixed-angle junction for stable mechanical alignment

How to use

Select the T-connector where the main duct run must split into a smaller branch and ensure all mating ducts and pipes match the specified diameters. Prepare mating ends by cleaning and deburring, then insert or align ducts into the connector until seated. Apply compatible seals or adhesive if the installation specification requires air-tight or watertight joints. Secure the assembly according to local practice, using clamps, brackets or fasteners as needed, and verify alignment and flow after installation.

What to consider before purchase

• Confirm that the duct diameters in your system match 75 mm and 45 mm connections
• Check whether your application requires specific pressure or leakage ratings
• Verify material compatibility with any media (air, condensate, or wastewater) used in the system
• Ensure available installation space accommodates the fixed geometry of the T-connector

Usage recommendations

Install in straight, accessible sections for easier sealing and inspection; where airtightness is required, add appropriate gaskets or sealants and perform a leakage test following installation. Regularly inspect the junction for buildup, blockages or mechanical stress in periodic maintenance routines.
