STjh compact 52 by 44 inch passive personnel airlock with powder-coated shell and interlocked swing doors

STJH-PERSONNEL-AIRLOCK-52X44-PASSIVE

Cleanroom Personnel Airlock 52 × 44 in Passive

A compact neutral-air personnel vestibule that controls door sequencing without an active fan-filter unit.

One-person compact chamber
No integral blower
Emergency interlock release

Introduction de produit

This passive personnel airlock uses a 52 x 44 in nominal footprint and a 39.5 x 36 in usable chamber for one-person transitions. Interlocked doors limit simultaneous opening, while an interior emergency release and maintenance bypass support safe operation. Because it has no blower, it suits facilities where the surrounding HVAC system and gowning procedure provide the pressure and cleanliness strategy.

Key Features

Neutral transition zone

The unpressurized chamber separates door openings while avoiding an additional active airflow source.

Controlled door sequence

The interlock blocks simultaneous access and includes an emergency release from inside the enclosure.

Simple retrofit service

A powder-coated body and no FFU reduce overhead filter-service requirements at constrained entries.

Applications

For basic personnel transitions between controlled rooms where a neutral pause and disciplined door sequence are required. The surrounding HVAC design must supply any necessary pressure cascade because this model does not actively purge or pressurize its chamber.

Solutions for Your Application

Opening adjacent room doors together disrupts the pressure boundary.Use the interlock to force one-door-at-a-time passage through the neutral chamber.

A powered FFU would add maintenance where no active purge is needed.Select the passive no-blower format and rely on the validated room HVAC pressure scheme.

Options disponibles

Choose powder-coated or stainless construction, panel material, access controls, indicator lights and door handing. Voltage is required for controls even though the chamber has no blower.
