JPK-RBW

Cylindric radial diffuser for industral applications and large rooms

Cylindrical diffuser with adjustable control cone for a horizontal or vertical distribution pattern
Control cone can be adjusted manually, via electric motor or through a thermal drive (no external power required)
Ensures draught-free ventilation even with large air volumes and temperature differences
Optimized for spaces such as production halls

Design

The JPK-RBW circular radial diffuser features a perforated sheet cylinder with a closed base plate, as well as an internal height-adjustable control cone. The distribution pattern is adjusted by moving the control cone manually, by electric motor or via a thermal drive without auxiliary power.

The diffuser’s design enables air directions ranging from diagonally upwards to vertically downwards. The umbrella-shaped radial air discharge ensures draught-free ventilation of large room areas, in particular in cooling mode, even with large air volumes and temperature differences.

Due to the comparatively high air flows that can be achieved, this diffuser is primarily used in production halls with large room volumes.

Functionality

Air enters the control cone through the spigot. Depending on the control cone’s position, it produces either vertical air discharge (“up” position) or radial air discharge with a diagonally upward axis (“down” position). Between these end positions, the distribution pattern can be infinitely varied by continuously adjusting the cone.

This adaptation enables good flushing of the occupancy zone in heating and cooling mode according to the specific operating conditions.
