STjh 52 by 72 inch pressurized personnel airlock with roof HEPA fan-filter unit and two-person chamber

STJH-PERSONNEL-AIRLOCK-52X72-PRESSURIZED

Cleanroom Personnel Airlock 52 × 72 in Pressurized

A two-person HEPA-pressurized airlock that purges the chamber between controlled rooms with different pressure levels.

Two-person 39.5 x 64 in chamber
EC HEPA fan-filter unit
Variable pressure adjustment

Introduction de produit

The deeper 52 x 72 in model provides a 39.5 x 64 x 83 in usable chamber for approximately two occupants. A ceiling-mounted 2 x 4 ft EC fan-filter unit supplies HEPA-filtered air, while low vents discharge the purge flow and a variable control supports pressure balancing. Room-side filter access reduces the need for overhead service entry.

Key Features

Active chamber purge

Filtered supply air dilutes particles admitted during door opening before the next door is released.

Pressure balancing

Variable blower speed and low return vents support adjustment to the adjoining room cascade.

Room-side filter service

The ceiling FFU can be configured for clean-side filter replacement without entering the plenum.

Applications

For biotechnology, pharmaceutical and controlled manufacturing entries where personnel must pass between rooms with different pressure targets. Purge timing and blower setpoint should be commissioned against the actual leakage and adjacent-room airflow.

Solutions for Your Application

A passive vestibule cannot rapidly remove particles introduced with two occupants.Use the EC FFU purge and establish a delay before the clean-side door becomes available.

Filter replacement would normally require disruptive ceiling access.Specify room-side-replaceable HEPA construction and reserve internal service clearance.

Options disponibles

Available choices include stainless construction, smart pressure control, touchless door activation, access modules, alarms and purge timers. Final voltage and control logic can match the facility system.
