Installation Note: Choosing the Right Plenum Box Type

When specifying and installing Ventmann Plenum Boxes, the orientation of the HVAC ductwork connection (where the air comes from) dictates the optimal box type for best acoustic and thermal performance.

Key Installation Observation:

For "From Above" (Top Entry) Installations: Please select the Acoustic Plenum Box (GTG Series). This type is designed to primarily address and mitigate sound transmission from the ducting system into the occupied space, which is typically the priority for vertical (top) connections.
For Lateral (Side Entry) Installations: Please select the "V" Shape Insulated Thermo Box (VTBOX Series). This type is insulated and features the specific "V" shaped air path required for optimal thermal regulation and air delivery when connecting from the side.

Ductwork Reducer / Taper

Constructed from 24-gauge light galvanised steel, this ductwork reducer provides a reliable solution for connecting ducts of different diameters.

Large End: Available in sizes from 100 mm to 300 mm
Small End: Available in sizes from 80 mm to 280 mm

Both ends feature a male connection, allowing them to slide directly into spiral ducting. To connect with other male-ended components, a female coupler is required.

Designed for efficient airflow and seamless transitions, this reducer is ideal for linking two ducts of varying sizes in HVAC systems. Its sturdy galvanised steel construction ensures durability, resistance to corrosion, and long-lasting performance in ventilation installations.

How to connect

Ductwork Reducer / Taper

Ease of Installation

This ductwork reducer is crafted from 24-gauge light galvanised steel, offering a durable and reliable way to connect ducts of differing diameters. Its pressed steel construction ensures a precise fit and long-lasting performance, making it ideal for both spiral and flexible duct systems.

Large End: Sizes range from 100 mm to 300 mm
Small End: Sizes range from 80 mm to 280 mm

Both ends feature a male (SE) connection, allowing the reducer to slide directly into spiral ducting. When connecting to other male-ended components, a female coupler is required to complete the assembly.

Engineered for smooth airflow and efficient system performance, this reducer creates seamless transitions between ducts of different sizes. Its robust galvanised steel design provides excellent corrosion resistance and ensures the component maintains its integrity over time.

Perfect for HVAC installations, this ductwork taper combines strength, precision, and ease of use, making it a dependable solution for linking various duct sizes while maintaining optimal airflow throughout the system.
