Technical purpose PSWC, SKKA, SKKU and SKHA plenum boxes form a comprehensive solution for air supply and air extract applications in commercial and public buildings such as offices, conference rooms, retail spaces and similar environments. The range is designed for suspended ceiling installations and combines easy installation, low sound levels and accurate airflow control.
PSWC is the reference product. It is a quiet, ceiling-mounted extract plenum box with an integrated perforated air diffuser, specifically designed for installation in 600 × 600 mm suspended ceiling systems, where it replaces a standard ceiling tile. The diffuser frame is integrated with the plenum box, while the perforated face panel is attached using magnet holders and safety strings, allowing safe opening and easy access for cleaning and maintenance.
Thanks to the high perforation rate of the face panel, PSWC ensures very low sound levels over a wide airflow range. The diffuser is suitable for extract air applications and is available with or without internal sound attenuation lining. The plenum box is manufactured from galvanised sheet steel, while the perforated face panel is finished in RAL 9003 colour with a 70% gloss level. The sound attenuation lining, when selected, is made of polyester fibre. PSWC is available with duct connection diameters from 160 to 400 mm.
SKKA and SKKU are plenum boxes with round duct connections, suitable for various types of round diffusers (such as NWPA, NWPP and ODZA). The SKKA type is intended for diffusers without a gasket on the collar, while SKKU is designed for diffusers equipped with a gasket. Both versions can be supplied with or without sound attenuation lining and can be equipped with the ZAEF measurement and adjustment damper, which enables balanced and accurate airflow values. The damper can be easily removed without changing the setting. These plenum boxes can be used for both supply and extract air applications. They are manufactured from galvanised sheet steel and are available with duct connection diameters ranging from 100 to 630 mm.
SKHA is a plenum boxe with an open bottom, dedicated to square face panel diffusers (for example PWKA and PZKA). SKHA plenum boxes are available with or without sound attenuation lining and can be supplied either without a regulation damper or with the patented ZAEF measurement and adjustment damper.
SKHA plenum boxes are manufactured from galvanised sheet steel and are available for four face panel sizes ranging from 400 × 400 mm up to 625 × 625 mm, with duct connection diameters from 160 to 400 mm.
