Dynamic Garment Storage Cubicle (DGC)
Engineered for aseptic change rooms to maintain sterile cleanroom suits, hoods, and booties in a continuous ISO Class 5 laminar downflow environment. Prevents airborne microbial deposition on garments between gowning shifts.
Engineering Overview & Fluid Dynamics
Active contamination barrier and laminar downflow principles
The Himalayan Steel Dynamic Garment Storage Cubicle (DGC) is an active laminar flow storage station designed for pharmaceutical Grade B/C change rooms. Cleanroom garments that have been autoclaved or laundered can accumulate settling airborne particulates if hung in passive wardrobes. The DGC circulates filtered laminar air downward at 0.45 m/s across suspended suits and through perforated base shoe shelves, ensuring that cleanroom garments remain in pristine Class 100 condition ready for immediate donning.

Cleanroom Construction & Architectural Design
cGMP sanitary fabrication details from our Baddi engineering works
Top of cabinet is built at a 30-degree sanitary slope, making it impossible for operators to place items on top and eliminating dust accumulation.
Electropolished stainless steel rod fitted with welded spaced captive hangers to ensure cleanroom suits do not touch and block downflow air.
Heavy-duty perforated SS 304 base shelf allows downward laminar air to flow through shoe compartments before returning to side ducts.
Double-door design with flush-mounted toughened safety glass view windows and full-length continuous stainless piano hinges.
Extruded silicone gasket with embedded magnetic strip ensures positive airtight closure against positive cabinet air pressure.
Direct-drive dynamically balanced blower operates silently under 62 dB(A), keeping change room environments quiet.
Standard Operating Protocol (cGMP SOP)
Standard operating guidelines and contamination control sequence
Step-by-Step Material Transfer Sequence
Sanitization & Wipe-Down Protocol
- Wipe internal walls, hanger bars, and shoe racks weekly with 70% filtered IPA.
- Clean viewing glass panels with non-streaking cleanroom glass cleaner.
- Wash base pre-filters monthly in purified water.
Fail-Safe Interlock Protection
- Automatic door microswitch turns off UV germicidal lamp immediately if door is opened.
- Blower differential pressure alarm warns if HEPA filter becomes restricted.
Optional Engineering Customizations
Site-specific hardware adaptations
- Digital UV timer with programmable night-time automated sterilization cycles
- Individual numbered stainless key locks or RFID electronic badge card access
- Stainless steel wire-mesh glove and hood storage baskets
- HEPA filter differential pressure transmitter with BMS network connectivity
- Stainless steel floor leveling pads or lockable polyurethane wheels
Quality Validation Package (DQ/IQ/OQ)
Audit-ready documentation for US FDA and EU-GMP inspections

Cleanroom Design Highlights
- Continuous sterile laminar downflow keeps laundered cleanroom suits dust-free
- Sloped top design prevents dust accumulation on top of the cabinet in change rooms
- UV-C germicidal light cycle decontaminates garment surfaces during off-shift hours
- Bottom perforated shoe compartments allow downflow air to sweep through booties
