Sala limpia retorno de aire Riser Panel de pared por
A 100 mm hollow wall module that combines a vertical return-air pathway, low-level intake grille and optional pre-filter within the cleanroom partition, avoiding a projecting external return duct.
- Concealed Return-Air Path
- Low-Level Intake Grille
- Flush Wall Integration
- Accessible Pre-Filter Option
Introducción del producto
The Cleanroom Return-Air Riser Wall Panel replaces a separate floor-to-ceiling return column with a prefabricated hollow module. Room air enters through a flush grille near floor level, travels upward inside a protected channel and connects to the recirculation plenum or return duct above the ceiling. Gypsum lining and aluminum honeycomb reinforcement stiffen the wide cavity without blocking airflow. A lift-out or hinged intake section gives maintenance access to the optional coarse pre-filter while the remaining wall face stays aligned with adjacent cleanroom panels.
Características clave
Low-wall collection removes air near the zone where heavier particles tend to settle.
A flush stainless steel or coated grille preserves a smooth partition profile.
The optional washable pre-filter can be reached from the clean side through a dedicated cover.
Factory-formed top and bottom transitions reduce leakage around the riser connection.
Preocupaciones del producto del cliente
Return-wall concerns center on lost floor space, inaccessible filters, noisy air velocity and leakage at duct transitions.
Conventional boxed return columns project into the cleanroom and reduce usable floor area.The hollow riser occupies the same plane and modular width as the surrounding partition.
A concealed pre-filter becomes difficult to wash when there is no clean-side access.A removable lower grille exposes the filter without opening the complete wall assembly.
An undersized intake creates excessive velocity and objectionable airflow noise.Single- or double-riser grille areas can be selected to provide a broader low-level return path.
Gaps at the ceiling connection allow air to bypass the intended return route.A formed top collar and sealed vertical channel direct the captured air into the return plenum.
