Boxes

PEFLEX INOX
PLENUM BOXES

Expansion boxes connect one to several ventilation ducts to supply and exhaust anemostats mounted in rooms. Their design reduces the speed and noise of the air flowing through them.

 

 

The distinguishing feature of PEFLEX Inox boxes is their construction from highly durable, resilient, and weather-resistant stainless steel. Additionally, they are equipped with convenient CLICK system connection sockets for ducts, featuring built-in gaskets to facilitate the installation of the entire system.

 

PEFLEX Inox plenum boxes are available in standard angled versions, as well as pass-through and directional (for long-range nozzles), as well as countless other variants, making it possible to adapt them to any situation on the construction site.

System CLICK couplers

CLICK means fast and tight

The CLICK system used in the couplers enables very fast installation of ventilation ducts in the boxes with just one movement, without the need for manually fitting gaskets on ducts and using specialized tools. Thanks to the implementation of this system, installation is easier and faster, and the ducts are additionally protected against unintentional disconnection.

Installation of PEFLEX ventilation ducts in the boxes

1

Before inserting the duct into the connection socket, use a special PEFLEX cutter to cut its end straight.

2

Thanks to the gasket mounted inside the socket, there is no need to apply it as a separate element on the duct.

3

The trimmed ventilation duct should be inserted into the socket of the box until you hear a “click!”

4

Install the remaining PE-FLEX ducts into the box in the same way.

Choose optimally for your needs

Metal PEFLEX plenum boxes are available in virtually any configuration, allowing for the design and implementation of a ventilation system perfectly tailored to the building’s needs.

Three types of boxes: angular, pass-through, and directional, with the possibility of connecting various numbers of ducts of three diameters, as well as different sizes of ventilation valves, provide a vast number of options to choose from.

Different types of installation

Perfect for any situation

PEFLEX INOX plenum boxes have mounting ears on both sides and are suitable for both floor and ceiling installation.

The universal design also makes it possible to hide them under the floor, as well as to install them in the ceiling and directly embed them in concrete.

Pass-through or directional versions also facilitate wall mounting of the boxes.

Robust and durable

Entirely made of steel
stainless

We focus on quality. 

Therefore, our PEFLEX INOX plenum boxes are entirely made of thick stainless steel, ensuring excellent durability and resistance to various operating conditions, as well as long-term durability. The welded construction along with CLICK system sockets maintain high sealing of the entire installation.”

Adjustable length of the spigot

Without additional extensions

PEFLEX stainless steel plenum boxes come standard with a 5 cm long spigot in either socket (for connecting the diffuser frame) or nipple (for extension) versions.

Additionally, it is possible to order boxes with a pre-fabricated spigot up to 40 cm in length, eliminating the need for additional extensions on site.
