Stainless Steel Pass-Through Chambers
Interlocked transfer windows for ISO-classified cleanrooms, pharmaceutical labs, and controlled environments. HEPA-filtered and static models available.
Engineered for Controlled Transfer
Every pass-through we supply is specified to match your cleanroom classification, wall construction, and material transfer workflow — from simple static chambers to HEPA-purged dynamic units with electronic interlocks.
Interlocked Door System
Electromechanical interlocks prevent both doors from opening simultaneously, maintaining chamber integrity and preventing unfiltered air bypass.
HEPA & ULPA Filtration
Optional HEPA (99.97% @ 0.3 µm) or ULPA (99.9995% @ 0.12 µm) filtration for dynamic pass-throughs purges the chamber with filtered air before inner door opens.
Stainless Steel Construction
Type 304 stainless steel or powder-coated steel construction — easy to wipe down, corrosion-resistant, and suitable for pharmaceutical and biotech environments.
Custom Sizing & Configurations
Available in single and double-sided configurations with custom dimensions to fit your wall construction and material transfer workflow.
ISO 14644 Compatible
Designed to maintain ISO Class 4 through ISO Class 8 cleanroom classifications. Dynamic models support ISO Class 5 and cleaner environments.
USP 797/800 Compliant
Meets USP <797> and <800> requirements for pharmaceutical compounding and hazardous drug handling in hospital and clinical settings.

Static vs. Dynamic — Which Do You Need?
Static pass-throughs are unpowered chambers with interlocked doors — the right choice for most general lab and cleanroom applications where the primary goal is preventing simultaneous door opening.
Dynamic (air-purge) pass-throughs add a HEPA blower that purges the chamber with filtered air before the inner door opens — required for ISO Class 5 and cleaner environments, pharmaceutical manufacturing, and any application where particulate transfer during material exchange must be eliminated.
