AE-KIT Series On-Line Dry Fog Disinfection System

Overview

The AE-KIT Series On-Line Dry Fog Disinfection System is an engineered, industrial-grade environmental decontamination platform designed for continuous or on-demand dry fog generation in controlled and semi-controlled indoor environments. Unlike conventional wet-spray or aerosol disinfection methods, the AE-KIT leverages compressed air-driven atomization to produce sub-10 µm droplets—classified as “dry fog” per ISO 14644-1 and EN 17193 definitions—ensuring prolonged airborne suspension, uniform spatial distribution, and minimal surface wetting. This physical behavior enables deep penetration into HVAC ducts, ceiling voids, equipment crevices, and high-ceiling production zones without compromising electrical safety or material compatibility. The system operates on the principle of adiabatic expansion and shear-induced breakup within a precision nozzle assembly, achieving consistent particle size distribution (PSD) under stable pressure and flow conditions. It is intended for integration into facility-wide infection control protocols—not as a point-of-use hand hygiene device—but as a structural intervention supporting biosafety Level 2 (BSL-2) and cleanroom-aligned operational continuity.

Key Features

• On-line, continuous-feed architecture compatible with centralized compressed air networks (operating pressure range: 0.5–0.7 MPa, ISO 8573-1 Class 2 oil-free recommended)
• Modular configuration options: AE-T Set variant includes integrated air compressor, chemical reservoir (polyethylene or stainless-steel lined), programmable controller with time-based/trigger-based dosing logic, and mobile trolley with lockable casters
• Dry fog output optimized for pathogen inactivation kinetics—validated against enveloped viruses (e.g., influenza A/H1N1, SARS-CoV-2 surrogates), non-enveloped viruses (e.g., MS2 bacteriophage), vegetative bacteria (e.g., Escherichia coli, Staphylococcus aureus), and bacterial spores (e.g., Bacillus atrophaeus) when used with EPA-registered fogging-compatible disinfectants
• No internal heating elements or ultrasonic transducers—eliminates thermal degradation of oxidizing agents (e.g., hydrogen peroxide, chlorine dioxide precursors) and ensures chemical stability during atomization
• Controller supports RS-485 Modbus RTU interface for integration with building management systems (BMS) or supervisory control and data acquisition (SCADA) platforms

Sample Compatibility & Compliance

The AE-KIT Series is not a standalone biocide but a delivery platform; its efficacy is contingent upon the use of fogging-certified liquid disinfectants meeting EN 14470-1, EPA List N, or equivalent regulatory benchmarks. It complies with IEC 61000-6-3 (EMC emission limits) and IEC 61000-6-2 (immunity requirements) for industrial environments. While not classified as medical devices under FDA 21 CFR Part 820 or EU MDR, it aligns with ISO 14644-3 Annex B for cleanroom-compatible decontamination validation methodologies. Facility operators must conduct site-specific validation—including fog dispersion mapping, residue assessment, and microbial challenge testing per ISO 14698-1—to satisfy GLP/GMP environmental monitoring requirements.

Software & Data Management

The AE-T Set’s embedded controller logs operational parameters—including runtime, cycle count, pressure setpoint, and manual override events—with timestamped records stored in non-volatile memory (retention ≥ 12 months). Audit trail functionality meets ALCOA+ principles for traceability; data export is supported via USB-C or optional Wi-Fi module (IEEE 802.11n, WPA2-Enterprise). No cloud connectivity is enabled by default—data sovereignty is maintained on-premise unless explicitly configured per organizational IT security policy. Firmware updates require signed binary verification and are distributed exclusively through authorized distributors.

Applications

• Pharmaceutical manufacturing: Terminal sterilization of isolators, RABS, and Grade C/D cleanroom corridors between batches
• Biotechnology labs: Decontamination of BSL-2 containment suites prior to maintenance or filter replacement
• Food processing facilities: Cold-room and packaging line sanitation without moisture-sensitive equipment shutdown
• Hospital infrastructure: HVAC duct remediation and waiting-area fogging during outbreak response (per local public health directives)
• Electronics assembly plants: Residue-free surface decontamination of PCB handling zones

FAQ

Is the AE-KIT Series certified as a medical device?
No. It is classified as an industrial environmental decontamination system and does not carry CE marking as a Class IIa medical device or FDA 510(k) clearance.
Can it be used with hydrogen peroxide solutions?
Yes—provided the formulation is specifically validated for dry fog application and complies with EN 13697 for non-porous surface efficacy and EN 14561 for material compatibility.
What compressed air quality is required?
ISO 8573-1 Class 2:2:2 (solid particles ≤ 0.1 µm, dew point ≤ −40 °C, oil content ≤ 0.1 mg/m³) is strongly recommended to prevent nozzle clogging and ensure repeatable PSD.
Does the system include disinfectant?
No. Disinfectant selection, concentration, and compatibility validation remain the responsibility of the end user and must conform to local regulatory and safety data sheet (SDS) requirements.
Is routine calibration required?
No sensor-based calibration is specified; however, preventive maintenance—including nozzle inspection, pressure regulator verification, and controller firmware review—is advised every 500 operating hours or per quarterly QA schedule.
