Brand: KAAS
Product: Dynamic Pass Box
Product Type: HEPA-Filtered Cleanroom Transfer Chamber
Applications: Controlled transfer of materials between clean and non-clean areas
The KAAS Dynamic Pass Box is designed for the controlled transfer of materials between cleanrooms and adjacent non-clean or lower-classified areas.
Unlike a static pass box, the dynamic pass box uses HEPA-filtered airflow to blow loose particles from the surface of transferred items before the clean-side door is released.
The system helps reduce contamination transfer during the movement of tools, components, packaging materials, samples and production items without requiring personnel to enter or leave the cleanroom.
The chamber incorporates electrically interlocked doors so that both doors cannot be opened at the same time. This allows the pass box to function as an airlock and helps maintain separation between clean and non-clean areas.
The KAAS Dynamic Pass Box is suitable for pharmaceutical production, food processing, electronics, semiconductor manufacturing, medical-device facilities, biotechnology laboratories and other controlled environments.
Redmark Industry Sdn Bhd supplies KAAS Dynamic Pass Boxes in Malaysia with application consultation, dimensional customisation, installation, commissioning and after-sales technical support.
The general operating sequence is:
The KAAS Dynamic Pass Box is suitable for transferring:
◆ HEPA-filtered recirculating airflow
◆ Dynamic air shower function for transferred items
◆ H13 or H14 minipleat HEPA filter configuration, subject to final specification
◆ Stated filtration efficiency up to 99.999% at 0.3μm
◆ Electrically interlocked doors
◆ Only one door can be opened at a time
◆ Double-wall stainless-steel construction
◆ Glass viewing panels
◆ Adjustable air-shower cycle
◆ UV light with operating-hour meter
◆ Differential-pressure gauge across the HEPA filter
◆ DOP test port upstream of the HEPA filter
◆ Fluorescent or LED chamber lighting
◆ Centrifugal blower designed to reduce vibration and noise
◆ Customisable internal and external dimensions
◆ Powder-coated steel or stainless-steel construction options
◆ Suitable for installation between clean and non-clean areas

A dynamic pass box is normally recommended where the customer requires active filtration and particle removal during the transfer cycle.
Available options may include:
For pharmaceutical, food, medical-device and higher-cleanliness facilities, full SS304 construction is normally the preferred configuration.
SS316 may be considered where stronger corrosion resistance or a specific customer requirement applies.
The KAAS Dynamic Pass Box may be configured with:
Door orientation and wall thickness must be confirmed before manufacturing.
UV-C light may support supplementary surface treatment, but it should not be presented as a guaranteed sterilisation method unless the cycle, intensity, exposure and validation are specifically defined.
Shadowed areas may receive limited UV exposure.
The exact HEPA grade should be confirmed before publication or order placement. Avoid promising H14 unless it is included in the approved specification.
The dynamic pass box is intended to remove loose particles and reduce contamination transfer.
It does not replace:
The pass box supports contamination control but does not independently establish or guarantee the cleanroom’s ISO classification.
The customer should confirm:
