Ventilated pass-through for classified environment transition
Ensure sterile and secure transfer between environments with this ventilated pass-through, featuring interlocked doors and HEPA filtration, ideal for maintaining cleanliness and containment in critical processing areas.

Controls Airflow and Material Transfer
The BU-IV Ventilated Pass-through with Interlocked Doors from Comecer is designed for environments demanding stringent contamination control, such as radiopharmaceutical, nuclear medicine, and pharmaceutical settings. This equipment specializes in maintaining pure airflow during material transfers between areas, utilizing a HEPA filter and positive pressure system to ensure containment. The interlocked doors prevent simultaneous opening, safeguarding the classified environments from potential exposure. Capable of handling both solid and gas products, the BU-IV boasts manual and continuous operation modes, ideal for processes like filtration, ventilation, and decontamination. Its stainless steel construction, welded through the TIG method, ensures resistance to corrosion and facilitates thorough cleaning. Furthermore, the system integrates seamlessly into existing production lines, allowing easy integration with minimal disruption. Designed to meet GMP standards, it ensures the safety of both personnel and sensitive materials. Customization options are available to fit specific industrial needs, supported by comprehensive engineering support.
