PRODUCT DETAILS
High-volume airflow with precise, flexible control
Designed as a large indoor air cooler for localized room comfort, ST-888 combines a 20L water tank with 24-step fan control, wide air-direction adjustment and convenient digital operation. The feature set is suitable for distributors, retailers and appliance brands evaluating an evaporative air cooler for OEM/ODM programs.
90° Horizontal Airflow
Left-right air delivery covers approximately 90° in total, helping the air cooler fan distribute airflow across a wider indoor area.
90° Vertical Airflow
Up-down air direction is also adjustable across approximately 90°, making it easier to direct airflow toward different seating and room layouts.
24-Speed Digital Control
Fine speed adjustment from low to high gives buyers more control than conventional 3-speed fans, with the selected level shown clearly on the digital display.
Up to Approx. 12m/s
The specified air-speed range is 4.5–12m/s (±10%), supporting stronger circulation for a standing air cooler in larger personal or shared spaces.
20L Water Tank
A large-capacity water tank supports extended water-assisted evaporative cooling without the frequent refilling associated with compact personal air coolers.
Normal / Natural / Sleep Wind
Three wind modes provide different airflow patterns for daytime use, variable natural-style circulation and quieter nighttime-oriented operation.
10-Hour Timer
Timer settings increase in 0.5-hour steps from 0.5H up to 10H, giving users flexible scheduled shutoff for daily operation.
5m Remote Operation
The included remote control works within a specified range of up to 5m, allowing convenient operation from a desk, sofa or bedside area.
Negative Ion Function
An integrated ion function adds an additional air-treatment feature to the ST-888 configuration for markets where this functionality is requested.
Wide-Voltage Input
AC100–240V 50/60Hz input supports adaptation to multiple destination markets, subject to the final plug, cord and compliance configuration.
Customizable Power Cord
The standard exposed cable length is 2m, and cord length can be evaluated according to buyer requirements and target-market specifications.
Retail-Ready Accessories
Standard accessories include one user manual, one remote control and two ice crystal packs for a complete packaged configuration.
