Pengenalan Produk

This model is assigned to the return-air handler, where it treats molecular contaminants released by processes, materials and maintenance activities within the fab. An application-specific hybrid sorbent targets the documented mix of acids, bases or organics, with capacity expressed in ppb-h for life estimation. Because the return stream can differ sharply from outdoor make-up air, its media balance and sampling plan should be based on in-room sources and recirculation concentration rather than copied from the MUA bank.

Ciri-ciri Utama

Recirculation-loop protection

The RAH position removes internally generated AMC before the same air is delivered back toward production zones and sensitive tools.

Process-tailored adsorbent blend

Media proportions can be centered on the acids, bases or organics released by the actual production steps served by the return system.

Measured lifetime framework

Combining ppb-h capacity with return-air concentration supports a more defensible replacement interval than pressure drop or odor observation.

Applications

Used in semiconductor return-air systems serving areas with process-emitted AMC, including lithography support, wet clean, etch and chemical handling zones. Sampling locations should distinguish room-generated loading from contaminants already present in make-up air.

Solutions for Your Application

The MUA media blend may not match the compounds generated inside the cleanroom.Characterize the return-air stream by process zone and choose the RAH blend from that internal source profile.

A single central sample can miss a high-emission branch and allow local breakthrough.Place monitoring points upstream and downstream of the relevant return section and review branch contributions when life is shorter than expected.

Pilihan yang boleh didapati

Specify return-air gas profile, served process zones, airflow, filter dimensions, media blend, access side, monitoring ports, changeout threshold and final-filter arrangement.
