Cleanroom Stainless Steel Equipment
Cleanroom Shelving
Product Overview
Cleanroom shelving is for buffering and turnover rather than long-term warehousing. Shelves have to let air through — a solid shelf creates a dead zone underneath where particles settle and accumulate — so clean zone shelving is usually perforated plate or wire mesh.
Types follow load and contents: wire mesh, lipped edge, railed, recessed multi-tier and heavy-duty cantilever. Wafer carriers and photomask boxes have dedicated transfer and storage racks.

Detailed Description
Why shelves are perforated or made of wire
In a vertical unidirectional-flow cleanroom, air moves from the ceiling downward and returns at floor level. A solid shelf is a baffle in that path, creating a low-velocity recirculation zone beneath it where particles settle and are never carried away. Perforated plate and wire mesh let air pass, so ventilation below the shelf stays effective. The trade-off is lower load capacity and the risk of small items falling through, so heavy loads and loose parts need trays. **Placement affects airflow too**: shelving pushed hard against a wall blocks the low-level return grilles. Leave a return air path, and account for it at the layout stage rather than afterwards.Selection References
