Semi-Active Pass-Through Hatch for GMP Cleanrooms
The unit is designed for the sterile and controlled transfer of tools, samples, and products. Thanks to its semi-active design and the ability to connect to an external ventilation system, the hatch minimizes the risk of contaminated air entering clean areas while reducing the overall load on room air filtration systems.
The construction is manufactured from high-quality AISI 304 or AISI 316L stainless steel with smooth surfaces resistant to routine cleaning and exposure to disinfectants. The working chamber is equipped with a laminar airflow system supplying purified air through a high-efficiency fine filtration unit, providing additional decontamination of transferred materials before they enter cleaner production zones.
The control system provides monitoring of the operating mode, door status indication, purge cycle time adjustment, and safe operation of the equipment. The differential pressure gauge enables continuous monitoring of airflow parameters and timely assessment of filter performance.
A tempered safety glass viewing window allows visual inspection of the chamber contents without opening the doors.
✅ Key Advantages and Design Features
Based on the actual operational characteristics of the equipment, the following advantages can be highlighted:
- Reliable Pressure Monitoring System
The hatch is equipped with a high-precision Magnehelic differential pressure gauge mounted on the front control panel. It allows real-time monitoring of pressure differentials and effective control of filtration system performance.
- LED Status Indication and Automatic Interlocking
An integrated LED indication system (red/green) clearly informs operators about the status of the doors. The electromagnetic interlock prevents simultaneous opening of both doors, eliminating the risk of unfiltered air entering the clean zone.
- Premium Materials – Stainless Steel Construction
The housing and working chamber are manufactured from high-quality brushed stainless steel. The material is resistant to regular cleaning with disinfectants, UV exposure, and aggressive cleaning agents.
- Airtight Design and Ergonomics
The doors are fitted with high-strength tempered glass viewing windows and a reliable sealing system. A perforated lower door panel optimizes air circulation and airflow distribution inside the chamber.
- Easy Integration into Ventilation Systems
The upper connection duct provides convenient integration with centralized exhaust or supply air ventilation systems.
