The use of HVAC (Heating, Ventilation, and Air Conditioning) systems in ISO 4 plenum design is essential for maintaining a cleanroom environment. An ISO4 plenum is an enclosure designed to help control air flow and temperature by directing air from a central area—the plenum—into individual workstations or rooms.

**IsoPlenum** is a plenum made of EPP (expanded polypropylene). EPP features a closed-cell structure, ensuring no moisture absorption. Weighing only 800 grams, this lightweight plenum does not require suspension from the building structure, resulting in significant savings on installation costs.

Cleanroom levels are available from Class 100,000 to Class 1 (ISO Standards Class 1 thru Class 8), Temperature and/or Humidity control may need to be considered. The standard system consists of Panelized Cleanroom Walls, available in various thickness and textures.

2021年10月12日 · Direct ducted systems work well for most life science cleanroom needs, quite capable of maintaining pressure, temperature, and humidity–the “Big Three” for cleanroom environments–at an ISO 7 or ISO 8 level. Plenums are particularly good at managing particulate counts, which is why they first saw adoption in cleanrooms built for ...

plenum. Recirculated air units, with downward discharge to supply plenums at the Interstitial level.

2021年7月6日 · For the most critical (ISO 6 and cleaner) applications, a wall panel made of FRP (Fiberglas-reinforced plastic) or PVC is affixed to the gypsum board using a cleanroom-grade sealant. The wall panels are caulked using a seam treatment to prevent microbes from colonizing within gaps in the walls panels.

ISO 6 cleanrooms utilize recirculating air to achieve acceptable micron ratings. Within these systems, the air is exhausted through low-return air grills back to the plenum where the HEPA or ULPA fan filter units reclean the air and draw it back into the cleanroom.

IsoPlenum is a plenum made of EPP (expanded polypropylene). EPP has a closed cell structure so there is no moisture absorption. The plenum weighs only 800 grams. Due to its low weight, this plenum does not need to be suspended from the structural construction. This results in considerable savings on installation costs.

Filtration for ISO-8 classification cleanrooms is done with HEPA filters. The best modular cleanroom design uses a negative pressure plenum with HEPA fan filter units in the ceiling and incorporated low wall air returns to achieve laminar air flow. The HEPA-filtered air sweeps dirt down to the floor and horizontally to the low wall air returns.

Filtration for ISO-7 cleanrooms are done with HEPA filters. The best modular cleanroom design uses a negative pressure plenum with HEPA fan filter units in the ceiling and incorporated low wall air returns to achieve laminar air flow. The HEPA filtered air sweeps dirt down to the floor and horizontally to the low wall air returns.
