Введение продукции

The dynamic pass box adds a self-contained fan and final-filter circuit to a double-door transfer chamber. Air returns from the lower chamber area, passes through filtration and re-enters via a ceiling diffuser to condition the payload zone. The internal loop avoids a building supply duct and can run a timed purge after the loading door closes.

Основные характеристики

An integral fan-filter loop conditions chamber air without external ductwork.

A broad ceiling diffuser supplies air across the payload footprint.

Low-level return slots collect particles released from packaging.

A filter-pressure indicator provides a maintenance signal.

Door logic can include a purge period before receiving-side access.

Обеспокоенность клиентов продуктами

Active transfer needs to remove particles generated inside the chamber without complicating room air balancing.

Carton surfaces shed particles after the dirty-side door closes.Repeated filtered recirculation sweeps the chamber before release.

One supply grille leaves stagnant zones around containers.A ceiling diffuser and distributed returns broaden the chamber airflow path.

A duct connection is difficult in a retrofit wall.The self-contained loop needs no room supply or return duct.

Filter loading quietly reduces the airflow.A differential-pressure display indicates rising filter resistance.
