DQP-1100 Portable Electric Aerosol Generator

Overview

The DQP-1100 Portable Electric Aerosol Generator is an engineered solution for targeted, wide-area dispersion of liquid disinfectants, insecticides, deodorizers, and humidifying agents in enclosed or semi-enclosed environments. It operates on the principle of high-pressure centrifugal atomization: a motor-driven rotating disc accelerates liquid formulation to the disc’s periphery, where surface tension rupture generates a polydisperse aerosol cloud with a mass median aerodynamic diameter (MMAD) ≤40 µm. This particle size range ensures optimal airborne suspension time (typically 10–30 minutes under standard indoor airflow conditions), enabling uniform spatial distribution and enhanced contact efficiency with airborne microorganisms, arthropods, and volatile organic compounds. Designed for operational flexibility, the unit requires no compressed gas supply or external air handling infrastructure—making it suitable for rapid deployment across dynamic facility environments without permanent installation.

Key Features

• Compact, ergonomic design with integrated handle and low center of gravity—enabling single-operator mobility across multi-level facilities, stairwells, and narrow corridors.
• High-efficiency brushless motor delivering stable rotational speed control, ensuring consistent aerosol generation across variable tank fill levels and viscosity ranges (compatible with aqueous solutions, alcohol-based formulations, and low-viscosity oil emulsions up to 15 cP).
• Adjustable nozzle geometry supports both wide-angle dispersion (for room-volume saturation) and focused directional output (for localized treatment of cargo holds, vehicle cabins, or storage racks).
• Two interchangeable reservoir options (500 mL and 1200 mL) constructed from chemical-resistant HDPE with calibrated fill-level indicators and leak-proof quick-connect seals.
• Thermal overload protection and auto-shutdown circuitry compliant with IEC 60335-1 safety standards for household and similar electrical appliances.

Sample Compatibility & Compliance

The DQP-1100 is validated for use with EPA-registered hospital-grade disinfectants (e.g., sodium hypochlorite, hydrogen peroxide, quaternary ammonium compounds), WHO-recommended vector control agents (e.g., pyrethroids), and non-corrosive odor-neutralizing solutions. It does not support suspensions containing particulates >5 µm, undiluted essential oils, or highly viscous glycol-based carriers. The device conforms to GB/T 28219–2011 (Chinese National Standard for Electric Disinfection Equipment) and meets electromagnetic compatibility requirements per GB 4343.1–2018 (CISPR 14-1). While not certified as medical equipment under FDA 21 CFR Part 820 or ISO 13485, its operational parameters align with environmental hygiene protocols referenced in ISO 14644-1 (cleanroom aerosol testing methodology) and CDC/NIOSH guidance for non-healthcare facility disinfection workflows.

Software & Data Management

The DQP-1100 operates as a standalone electromechanical system with no embedded firmware, Bluetooth, or cloud connectivity. All operational parameters—including runtime, total dispensed volume estimation (calculated via duty-cycle timing and nominal flow rate), and thermal status—are conveyed through dual LED indicators (power/on and overheat warning). For auditability in regulated environments, users are advised to log deployment metadata (location, start/end time, formulation lot number, operator ID) manually or via compatible facility management systems (e.g., CMMS platforms supporting CSV-based import). No data encryption, user authentication, or electronic record retention functionality is implemented—consistent with Class II non-instrumental environmental control devices under EU MDR Annex XVI exemptions.

Applications

• Hospital auxiliary spaces: terminal disinfection of waiting rooms, staff break areas, and non-critical equipment storage zones between patient cohorts.
• Public transportation infrastructure: fogging of bus interiors, train carriages, ferry cabins, and airport shuttle vehicles during off-peak maintenance windows.
• Food service logistics: residue-free decontamination of dry-goods warehouses, cold-chain inspection bays, and canteen preparation surfaces prior to shift handover.
• Emergency response: rapid pathogen suppression in temporary shelters, field hospitals, and quarantine transport units during outbreak containment operations.
• Archival preservation: low-moisture humidification of document storage vaults and museum artifact repositories where condensation-sensitive materials prohibit ultrasonic or evaporative methods.

FAQ

Is the DQP-1100 suitable for use in occupied spaces?

No. Aerosol generation must occur only in unoccupied, well-ventilated areas with controlled access. Personnel re-entry should follow product-specific contact time and ventilation clearance guidelines outlined in the applied chemical’s SDS.

Can the unit be used with corrosive biocides such as glutaraldehyde?

Not recommended. Glutaraldehyde and other high-pH aldehydes may degrade the HDPE reservoir and impeller coating over repeated cycles. Refer to the manufacturer’s chemical compatibility chart before introducing novel formulations.

Does the device require calibration or scheduled maintenance?

Yes. The rotating disc assembly should be inspected weekly for residue buildup and cleaned with isopropyl alcohol; bearing lubrication is required every 200 operating hours per GB/T 28219–2011 Clause 7.3.2.

What electrical safety certifications apply to this model?

It carries CCC (China Compulsory Certification) mark and complies with GB 4706.1–2005 for general safety of household and similar electrical appliances.

Is technical support available internationally?

Yes—authorized distributors provide multilingual documentation, spare parts logistics (impeller kits, seals, power cords), and remote troubleshooting aligned with ISO/IEC 17020 accreditation scope for field service providers.
