Misting nozzle Model 6109975 MicroWhirl® (MW)

for liquidshumidityatomizing

Description
BETE MicroWhirl® (MW) series nozzles provide fine misting and fogging through a pinless whirl (vortex) design for drip-free operation and consistent atomization. Supplied standard with a 70-micron polypropylene filter; 200-mesh 316 stainless steel filter optional. Minimum operating pressure: 100 PSI (7 BAR).

How it works
The nozzle converts fluid pressure into kinetic energy in a swirl chamber. Centrifugal forces break the liquid into very fine droplets; at lower pressures the device produces a fine mist, at higher pressures it produces fog. The whirl design improves reliability compared with impingement and air-atomizing types.

Applications

• Humidification
• Surface moistening
• Process cooling
• Dust suppression
• Odor control
• NOx removal / flue gas treatment
• Evaporation and evaporative cooling

Advantages

• Consistent fine atomization across pressure ranges
• Durable, pinless construction for reduced clogging
• Drip-free performance
• Standard 70 µm polypropylene filter; optional 200‑mesh 316 SS filter for harsher fluids
• Safety wire hole for securing the nozzle

Materials
316 Stainless Steel (body and wetted parts for MW series).

Weight: P6094622 ≈ 0.025 oz (≈ 7.09 g).

Notes
Delivered spray pattern and droplet suspension depend on operating pressure: lower pressures favor fine mist (longer airborne residence), higher pressures generate denser fog. Particle behavior will vary with ambient airflow.
