Cleanroom Material Handling and Storage
Negative Pressure Transfer Cart
A sealed mobile negative-pressure cart for contained transfer of contamination-risk materials between controlled processing areas.
- Inward airflow helps contain airborne material during transport
- HEPA-filtered exhaust protects surrounding controlled areas
- Differential-pressure monitoring provides visible containment status
Product Introduction
This cart combines a welded stainless enclosure, gasketed access doors, adjustable shelves and a fan-driven HEPA exhaust module. The fan maintains the chamber below ambient pressure so leakage airflow is directed inward, while analog and digital pressure indication helps operators verify containment during loading and movement.
Key Features
Gasketed doors and compression latches reduce uncontrolled leakage paths.
Pressure indication and alarm hardware make operating status apparent.
Onboard battery maintains containment during mobile transfers.
Perforated removable shelves promote an unobstructed internal airflow path.
Customer Product Concerns
Potentially contaminated loads must remain enclosed during movement while the surrounding controlled area is protected from outward leakage.
Particles escaping through cabinet gapsNegative pressure directs leakage airflow into the enclosure.
Contaminated exhaust reaching the corridorThe discharge stream passes through a dedicated HEPA filter.
Loss of containment going unnoticedDifferential-pressure display and alarm devices show system condition.
Power interruption during movementA rechargeable battery supports the exhaust fan between mains connections.
Typical Applications
Contained internal transfer of potent-compound containers, laboratory samples, quarantine materials and closed waste packages in pharmaceutical, biotechnology and research facilities.
Technical Parameters
Containment pressure, exhaust volume, filter arrangement and alarm limits are selected from a risk assessment of the handled material. The cabinet uses cleanable stainless surfaces, accessible filter housings and a mobile power system; final performance remains configurable for the intended protocol.
