High-Performance Entry Solutions
CleanSpace Specialty Portals are engineered for environments with rigorous safety, high-traffic, or specialized operational requirements. From UL-rated fire protection to space-saving automatic sliding systems, our specialty line ensures that complex entry requirements do not compromise the integrity of your modular cleanroom envelope.
These systems transition seamlessly from standard cleanroom environments to heavy-duty industrial applications, providing the same flush-mount precision found across the entire CleanSpace architectural line.
Our specialty portals address the most demanding facility challenges through advanced materials and automated technology:
UL-Listed Fire Protection
The Fire Rated Portal Elite™ provides a critical safety barrier, featuring fully welded stainless steel construction and UL-rated assemblies for fire-rated wall openings.
Automated Workflow
Slide Portal™ systems use motorized operation and touchless activation to manage high-traffic areas and space-constrained layouts without compromising environmental separation.
Premium Durability (Elite & Pro Series)
Our stainless steel and hybrid-stainless systems (Portal Elite™ and Pro™) offer maximum resistance to aggressive cleaning agents and heavy physical impact.
Seamless Integration
Every specialty door is designed for a flush frame-to-wall interface with Apex wall systems, maintaining the monolithic surface required for cGMP compliance.
Intelligent Controls
Fully compatible with cleanroom interlocking systems, building automation, and sophisticated access control hardware.
Specialized Industry Applications
These systems are purpose-built for industries where safety and high-cycle reliability are non-negotiable:
Biopharmaceutical Manufacturing
Fire-rated portals for hazardous material storage and high-durability stainless steel for aggressive decon cycles.
High-Traffic Logistics
Automatic sliding portals for material transfer zones where hands-free operation is required.
Medical Device & Labs
Precision-controlled sliding systems maximize usable floor space in compact laboratory footprints.
Industrial High-Tech
Heavy-duty portals ensure environmental continuity for cleanroom-adjacent industrial spaces.
Frequently Asked Questions
Our fire-rated systems are UL-listed assemblies. Specific ratings (e.g., 20/45/60/90 minute) are available based on the specific configuration and wall assembly requirements. Contact our engineering team for project-specific submittals.
Yes. Our automatic sliding systems feature safety overrides to allow for manual operation, ensuring facility egress and safety protocols are maintained during power interruptions.
For environments using aggressive vaporized hydrogen peroxide (VHP) or caustic cleaning agents, we recommend the Portal Elite™ (Full Stainless Steel) or Portal Pro™ (Hybrid Stainless) for superior corrosion resistance.
Yes. We specialize in custom configurations. While standard sizes are readily available, we can manufacture double-door and leaf-and-a-half configurations for extra-wide openings to accommodate large machinery or palletized transfers.
