Positif-Tekanan Bersih Transfer Pass Box
- HEPA-Filtered Supply
- Stainless Transfer Chamber
- Interlocked Access
- Selectable Airflow Controls
Perkenalan produk
A positive-pressure pass box is a dynamic transfer hatch that combines a fan-assisted air circuit with a small enclosed loading chamber. In the selected arrangement, filtered make-up air supplements recirculation to establish an outward pressure bias when both doors are closed. The stainless-steel interior, viewing doors and overhead air-distribution panel provide a practical enclosure for trays, packaged components and other clean materials.
Fitur utama:
A perforated supply panel spreads air across the chamber rather than through a single nozzle.
Viewing panels let operators check the load without opening a door.
Door interlocking supports a load-close-unload handling sequence.
Smooth internal surfaces provide access for routine wipe-down cleaning.
Solusi untuk aplikasi Anda
The air circuit and loading method need to work together, particularly when transferring delicate or particle-sensitive components.

Parameter teknis
The following are selectable common-reference configurations for this type of dynamic pass box, not a combined or tested STjh model specification. Positive pressure describes the intended closed-door operating arrangement; no fixed chamber pressure, recovery time or open-door protection level is stated.
| Bahan ruang | 304 stainless steel; 316 stainless steel available as an option |
|---|---|
| Internal Chamber Sizes (W × D × H) | 600 × 600 × 600 mm or 750 × 750 × 750 mm reference choices |
| Pasokan penyaringan | H14 HEPA filter; H13 available as an alternative filter configuration |
| Prefiltration | G4 prefilter |
| Airflow Arrangement | Recirculating vertical airflow with make-up air |
| Air Distribution | Overhead HEPA supply with a perforated diffuser |
| Door System | Two sealed viewing doors with electromagnetic interlocking |
| Pressure Indication | Differential pressure gauge |
| Pasokan Listrik | 220 V AC, single-phase, 50 Hz; 60 Hz configuration available |
| Customization (Kustomisasi) | Tersedia berdasarkan aplikasi yang dimaksudkan dan lingkungan operasi. |
Pilihan yang tersedia
A typical reference package uses a stainless-steel chamber, prefilter, fan-assisted HEPA supply and interlocked viewing doors. Optional selections include 316 stainless steel, an alternative HEPA grade, digital pressure indication and an adjustable door-release delay. The pressure measurement arrangement and any alarm or pressure-linked release function are separate control selections, not assumed standard features.
Selection and Installation
Choose the usable chamber size around the complete tray or container, leaving the supply diffuser and return openings unobstructed. Keep service space available for the fan, prefilter and HEPA filter rather than sealing the service face into the partition.
Chamber-to-room pressure and pressure drop across a filter are different measurements. A filter gauge alone does not demonstrate a positive chamber pressure. The make-up air and discharge arrangement must suit the pressure relationship on both sides of the wall. This product is for clean, non-hazardous materials, not hazardous-material containment or sterilization.
For loads that must remain on a cart, consider the floor-standing cleanroom pass box instead of lifting the cart contents into a small chamber.
