Explosion-Proof Laminar Flow Transfer Window | 99.999% Purification | GMP Pharma & Chemical Safe Pass-Through

Explosion-Proof Laminar Flow Transfer Window | 99.999% Purification | GMP Pharma & Chemical Safe Pass-Through

The Explosion-Proof Laminar Flow Transfer Window is a safety-critical contamination control system designed for secure material transfer in explosive atmospheres and high-cleanliness environments. Engineered for chemical, pharmaceutical, food, electronics, precision machinery, and aerospace industries, it combines ATEX-compliant explosion-proof construction with ISO Class 5 laminar airflow purification. Featuring a full 304 stainless steel body, integrated DOP testing port, and dual interlocking systems, it ensures safe, sterile transfers in GMP, VHP, and dust-free cleanrooms while mitigating ignition risks in volatile zones.

Key Features

ATEX-Compliant Explosion Protection:

Equipped with explosion-proof electrical components (box, pipe, lamp) and spark-resistant internal wiring, certified for use in Zone 1/21 hazardous areas.

ISO Class 5 Laminar Airflow:

Unidirectional airflow at 0.35–0.75 m/s achieves 99.999% particle retention efficiency, validated by DOP testing via the front-access port.

Industrial-Grade Durability:

Full 304 stainless steel construction resists corrosion, chemicals, and mechanical stress, ensuring longevity in harsh environments like chemical plants or pharma labs.

Noise-Optimized Operation:

Maintains noise levels between 55–65 dB (±5 dB) for minimal disruption in sound-sensitive cleanrooms or laboratories.

Dual Safety Interlocks:

Mechanical/electronic interlocking prevents simultaneous door opening, eliminating cross-contamination and ensuring operator safety during volatile material transfers.

GMP/VHP Compliance:

Seamlessly integrates with EU GMP Annex 1 and VHP decontamination protocols for sterile transfers in pharmaceutical and biotech facilities.

Application Scenarios

Chemical plants: Safe transfer of flammable solvents or reactive compounds between hazardous and controlled zones.

Pharmaceutical cleanrooms: GMP-compliant movement of APIs (Active Pharmaceutical Ingredients) or sterile packaging.

Food production: Hygienic pass-through of raw ingredients in ISO 22000-certified facilities.

Aerospace manufacturing: Contamination-free handling of precision components in dust-free environments.

Electronics assembly: Protection of microchips and sensitive devices from particulate contamination.
