In flameproof and explosion proof clean rooms, bottom openings are strategically designed to maintain airflow balance while ensuring safety and contamination control. These openings, typically located at lower wall sections or floor junctions, facilitate the downward laminar flow of clean air and the safe exhaust of contaminated air, maintaining positive pressure and ISO-class cleanliness.

Depending on the clean room’s classification and operational requirements, bottom openings may feature grilled return air vents, stainless steel perforated ducts, or explosion proof exhaust outlets. All designs are tailored to prevent spark generation, dust accumulation, and static discharge, aligning with ATEX/IECEx standards. The construction materials are non-corrosive, anti-static, and fire-retardant, ensuring a robust and compliant solution for hazardous environments.
