PRODUCT DETAILS
Large water capacity, fine airflow control and practical daily operation.
For B2B buyers comparing a standing air cooler or room air cooler with water, ST-898 concentrates the product story around measurable airflow, a 50L tank and easy-to-understand control functions instead of exaggerated cooling claims.
50L Large Water Tank
The large-capacity tank reduces refill frequency and supports longer water-assisted cooling sessions, making ST-898 suitable for larger indoor spaces and high-use scenarios.
25-Level Speed Control
Fine speed adjustment gives users more control than a basic three-speed air cooler fan. The digital display keeps the selected level easy to confirm.
6.7m/s Maximum Air Speed
Focused airflow reaches up to 6.7m/s, helping the unit deliver noticeable circulation while remaining positioned as an evaporative air cooler rather than a compressor air conditioner.
39.6m³/min Airflow
High-volume circulation supports wider room coverage and gives distributors a clear performance figure for product comparison and specification sheets.
Up / Down + Left / Right Airflow
Multi-direction air delivery helps distribute airflow across different seating or working positions instead of concentrating air in one fixed direction.
Three Wind Modes
Normal, Natural and Sleep modes provide different airflow patterns for daily use, relaxed environments and nighttime comfort.
Digital Display + Remote
On-product digital information and remote operation make the indoor air cooler easier to manage from across a room.
10-Hour Timer
A scheduled shutoff function supports overnight use, office operation and energy-conscious product positioning.
Low-Water Alarm
The low-water reminder helps users know when the tank needs attention, improving usability for a large air cooler with water tank.
Negative Ion Function
An integrated ion function expands the feature set for customers looking for a multifunction evaporative air cooler platform.
Child Lock
The child-lock function helps prevent unintended control changes in family-oriented indoor applications.
≤60dB Operating Noise
Controlled operating noise supports placement in living rooms, reception areas, offices and other indoor spaces where comfort matters.
