Boîte HEPA Pass autonome
An integrated fan-filter transfer hatch for cleanroom upgrades where a dedicated building air duct is unavailable.
- Integrated Fan and Filtration
- No Dedicated HVAC Duct
- Selectable Service Access
- Retrofit Wall Interface
Introduction de produit
The self-contained pass box brings the transfer enclosure and its air-cleaning components together for installation in an existing partition. Internal air passages connect the chamber to the fan and final-filter housing, avoiding a remote air-handler connection for the recirculating arrangement. Perimeter face frames finish the wall interface, while the location of access panels is chosen around the space available for upkeep.
Key Features
Coordinated access panels help reserve maintenance space at the usable side of the installation.
Wall finishing frames cover the partition edge without using the decorative trim as the load-bearing support.
Filter and fan selections can be matched to the usable chamber instead of an oversized remote system.
The selected lock and circulation controls provide a consistent operator interface for the transfer route.
Des solutions pour votre application
Refurbishment work needs a transfer hatch that can be fitted, supported and maintained in the space that actually exists.
The ceiling route cannot accommodate another air-supply branch.Select the internal recirculation configuration so the hatch does not depend on a new dedicated HVAC duct.
The filter fits in the cabinet but cannot be withdrawn after the wall is closed.Reserve the removal envelope and an accessible housing face before fixing the cabinet and adjacent furniture.
Different partition depths leave exposed edges around the opening.Match body projection and face-frame dimensions to the wall build-up, with a cleanable perimeter junction.
A replacement filter changes the resistance seen by the existing fan.Choose the element and blower together, then restore the required circulation setting after service rather than relying on physical fit alone.
Les applications typiques
Existing cleanrooms gaining a small-item transfer pointModular laboratory support partitionsMedical packaging room refurbishmentsNon-hazardous hospital support-material routes
The compact integrated concept is suited to prepared materials and closed containers whose transfer process calls for filtered chamber air. It is not a substitute for sterilization, biological containment or removal of solvent vapours; an internal recirculation path does not make those applications suitable.
Paramètres techniques
The selections below are common integrated-pass-box references, not dimensions or performance measured on an STjh unit. A self-contained design still needs a suitable electrical connection, adequate structural support and room for filter maintenance.
| Equipment Integration | Fan, final-filter housing and transfer chamber within one cabinet assembly |
|---|---|
| Compact Chamber Reference | 600 × 600 × 600 mm internal W × D × H; alternative proportions selectable |
| Body Material Selection | 304 stainless chamber with stainless or powder-coated external enclosure |
| Sheet Construction References | 1.0 or 1.2 mm stainless sheet for selected enclosure parts |
| Filtration terminale | H14 HEPA element to EN 1822 in an accessible housing |
| Upstream Filter | Separately serviceable particle prefilter |
| Airflow Arrangement | Internal chamber-air recirculation without a dedicated building supply duct |
| Supply Configuration Reference | 230 V AC, single phase, 50 Hz |
| Access Arrangement | Manually opened transfer doors with a selected one-door-at-a-time interlock |
| Filter Maintenance Access | Chamber-side or dedicated service-hatch arrangement, selected for the installation |
| Wall Interface | Perimeter face frames sized to the partition depth and cabinet opening |
| Control Options | Adjustable fan setting and programmable circulation or access-delay functions |
| Customisation | Disponible en fonction de l'application prévue et de l'environnement d'exploitation. |

The starting concept is an integrated fan-filter cabinet with two-sided material access. Frame dimensions, support method, accessible component locations and control functions are selected around the refurbishment. A replaceable filter element is not the same as a removable cassette containing the fan and controls; that service architecture must be selected specifically rather than assumed from the product name.
Selection and Installation
Start with the available wall opening, access from both rooms and the path needed to remove a filter after installation. A cabinet that fits between the wall studs may still be impossible to maintain beneath a ceiling obstruction or behind fixed furniture. Select the service face before positioning the hatch and keep that maintenance route accessible after installation.
Provide support for the loaded cabinet, keep the frame square and seal the room-facing perimeter without covering service fasteners. Specify the electrical termination to suit the actual supply rather than treating self-contained as a universal plug-in connection. This is an integrated installation choice within the dynamic-pass-box family; compare the HEPA-filtered dynamic pass box when chamber circulation and the load arrangement drive the selection.
