Clean Room Door

Clean Room Door — Airtight Hygienic Access for Pharmaceutical, Medical and Food Processing Environments

Clean rooms operate under strictly controlled environmental conditions — temperature, humidity, airborne particle count, and air pressure — to protect sensitive manufacturing or medical processes from contamination. The doors of a clean room are one of its most critical performance elements: they must seal the clean room envelope against uncontrolled air infiltration, maintain the required pressure differential between zones, resist contamination from surface irregularities, and withstand frequent cleaning and chemical disinfection without degradation.

Construction

Frame: IFES 100×50 mm galvanised steel (GI) frame — designed to be surface-flush with clean room wall panels, eliminating ledges and crevices that trap contamination. The frame profile is compatible with standard GMP-compliant clean room wall panel systems.

Shutter: 44 mm thick, fabricated from 0.8 mm or 1.0 mm GI steel on both faces. The door leaf is precision-engineered for flatness — no bowing or warping — to ensure consistent sealing contact with the frame rebate on every closure.

Core Infill Options:
- Honeycomb: Lightweight aluminium or paper honeycomb — for doors where weight is important and thermal/acoustic performance requirements are minimal
- PUF (Polyurethane Foam): Rigid foam infill providing excellent thermal insulation — for doors in temperature-controlled environments or between adjacent zones with temperature differentials
- Mineral Wool: Non-combustible insulation providing both thermal and acoustic performance — for clean rooms adjacent to mechanical plant or noisy production areas

Sealing System

Perimeter seals: Full four-side perimeter sealing against the frame rebate using EPDM or silicone gaskets — maintaining the door seal integrity through the full pressure differential range of the clean room HVAC system. Automatic drop-down bottom seal (mortise type): activates as the door closes to eliminate the floor gap completely — critical for maintaining positive or negative pressure differentials and preventing uncontrolled floor-level air infiltration or contamination ingress.

Vision Panel

Double-glazed glass panel: allows visual inspection of adjacent zones without opening the door — minimising the number of door opening cycles and the associated contamination risk and pressure disruption. Glazing is flush with the door face on both sides — no protruding beads or frames that collect dust.

Finish and Cleanability

All internal surfaces are smooth, radius-cornered, and joint-free, resistant to common pharmaceutical and food industry disinfectants including IPA, hydrogen peroxide, and sodium hypochlorite solutions. Powder coat finish in white or clean room standard colours.
