商品紹介

The positive-pressure transfer pass box supplies more filtered air than leaves through its controlled relief path, moving small leakage outwards instead of drawing room particles towards the payload. A fan, diffuser and pressure sensor maintain the selected chamber condition. Receiving-side access can be delayed until a purge and pressure recovery have completed.

主要な特徴

A filtered supply fan maintains a small positive pressure bias.

A defined relief path avoids reliance on door-gap leakage.

A full-width diffuser distributes clean air across trays and containers.

Pressure indication supports operational checks before release.

A timed purge clears loading-side air before clean-side access.

お客様の製品に関する懸念事項

Payload protection requires outward leakage control without excessive door force or uncontrolled airflow to adjacent rooms.

Room particles enter through minor gasket imperfections.Filtered positive bias drives leakage outward from the protected payload zone.

High pressure strains latches and complicates closing.A controlled relief path limits chamber pressure rise.

A narrow jet bypasses the load and leaves corners stagnant.A broad diffuser spreads supply air over the chamber.

The receiving door opens before loading-side air is displaced.A purge timer and pressure permissive control release.
