Nebulizing Diffuser Wholesale

What is Nebulizing Diffuser? (Two-Fluid Principle)

Nebulizing Diffuser is a type of two-fluid aroma diffuser, which is based on the Venturi effect and airflow shear atomization technology. Its core technology atomizes essential oil through high-speed mixing with compressed air. The mixture is then released via a dedicated nozzle, with no water or heating required.
 
The specific working process is as follows:
  1. Pneumatic Drive: Built-in air pump/compressor generates 0.2-0.5MPa high-pressure airflow with a flow rate exceeding 18m/s.
  2. Negative Pressure Liquid Absorption: High-speed airflow creates a negative pressure zone as it passes through the converging section of the venturi tube, automatically drawing out pure essential oils.
  3. Shear Atomization: Airflow and liquid mix violently at the nozzle outlet; the high-speed airflow shear force tears the essential oils into uniform droplets of 10-50 micrometers (some reaching nanometer scale).
  4. Aerosol Diffusion: The droplets form stable aerosols, which diffuse into the space using their own kinetic energy or an air conditioning system, resulting in a long-lasting fragrance without dripping.
Key advantages: The waterless design preserves the original aroma of essential oils, avoids high-temperature damage to aroma molecules (such as limonene and sapinene), achieves a diffusion efficiency of 92.6%, and covers an area of up to 8000 m³/80K ft².
WD Aroma provides a full range of diffusers to meet different space needs: its portable diffusers are suitable for spaces as small as 60 square meters, while the large-space diffusers covering up to 8000 m³/80K ft² are widely applied in hotels and luxury residences. In addition, WD Aroma provides OEM services for many world-renowned brands around the globe.
