Produkteinführung

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.

Key Features

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.

Verfügbare Optionen

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