Airlocks, Pass-Throughs & Clean Air Equipment

Protecting controlled perimeters during personnel and material ingress. Engineered in 304 and 316L stainless steel for effortless sanitization.

Technical Overview

Engineered Contamination Control

Over 80% of contamination in cleanroom environments is introduced during the transfer of personnel and materials. REINWERK engineers robust barrier equipment and dynamic airlock systems that isolate critical processes from external particulate contamination.

From high-velocity HEPA air showers that dislodge surface dust to motorized dynamic pass-through hatches with UV-C and VHP ports, our equipment provides unyielding barrier protection.

Key Engineering Features

Personnel Air Showers

High-velocity air nozzles (25-30 m/s) delivering filtered air jets to purge micro-particles from cleanroom garments prior to entry.

Dynamic Pass-Through Boxes

Equipped with internal HEPA recirculation, electronic magnetic door interlocks, differential pressure monitoring, and UV sterilization.

Laminar Flow Workstations

Horizontal and vertical clean benches providing localized ISO Class 3/4 (GMP Grade A) operating conditions on standard laboratory benchtops.

Aseptic Gowning Furniture

Stainless steel step-over benches, garment storage cabinets with internal HEPA purge, and hands-free touchless wash sinks.

Engineering FAQs

Frequently Asked Questions

What is the difference between static and dynamic pass-through boxes?

Static pass boxes have mechanical or magnetic door interlocks without active air filtration, suitable for non-critical transfers between similar cleanliness grades. Dynamic pass boxes feature active HEPA filtration, laminar airflow, and differential pressure to maintain positive pressure and purge particles during door opening.

Can pass-through boxes accommodate VHP bio-decontamination?

Yes, REINWERK supplies VHP-ready dynamic pass boxes equipped with airtight pneumatic gasket seals, injection/sampling ports, and automated cycle communication with external VHP generators.
