The 20L evaporative air cooler with negative ion function delivers evaporative cooling for commercial and industrial spaces. Built with a 150W motor and a centrifugal fan, this unit produces an air flow capacity of 2000 m³/h at a wind speed of 11.5 m/s. The 20L water tank supports extended operation between refills, while the built-in negative ion generator releases ions into the airstream. Designed with a 100% copper motor and ABS housing, this air cooler addresses the needs of business buyers seeking a durable cooling solution for warehouses, workshops, retail floors, and event venues. The unit includes a remote control, four castors for mobility, and automatic left-right oscillation to distribute airflow across a wider area.

This air cooler is equipped with a 20L unremovable water tank that holds enough water for extended operation periods. The tank can be refilled from the top of the unit without requiring removal, reducing downtime during commercial use. The larger tank volume means fewer refills throughout the day, which is beneficial for facilities that run cooling equipment during full business hours.
The unit offers three speed settings that allow operators to match airflow intensity to specific conditions. At the highest setting, the centrifugal fan delivers 2000 m³/h of air flow at 11.5 m/s wind speed. Lower settings reduce both power consumption and noise output, making the cooler suitable for environments where quieter operation is preferred.
The built-in negative ion generator releases ions into the outgoing airflow. This function can be activated independently of the cooling mode, giving users the option to use the ion feature alongside or separately from the evaporative cooling function. The control panel includes a dedicated button for the ion function.
The air cooler uses a 100% copper motor. Copper windings offer efficient thermal conductivity and consistent performance under continuous operation, which is relevant for commercial procurement teams evaluating equipment longevity and maintenance costs.
The unit comes with a remote control that allows users to adjust speed settings, activate the oscillation function, set the timer, and control the ion function from a distance. The 9-hour timer (remote type) enables scheduled operation, allowing the cooler to run for set periods without manual shutdown.
This evaporative air cooler serves a range of commercial and industrial applications. Warehouse and workshop operators use it to supplement ventilation in areas where traditional air conditioning is impractical or cost-prohibitive. Retail spaces and showroom floors deploy the unit to improve customer comfort during warm seasons. Event venues, exhibition halls, and temporary outdoor setups benefit from the castor-mounted design that allows relocation between areas. Dining areas and food service spaces also use these coolers to maintain airflow in patios and semi-open sections.
The air cooler measures 360×330×1000 mm and weighs 12.5 kg net (13.5 kg gross). Four castors are included as standard accessories, allowing staff to move the unit between locations without lifting equipment. The ABS housing provides impact resistance for environments where equipment is frequently repositioned. Loading capacity stands at 150 units per 20-foot container, 348 per 40-foot container, and 378 per 40-foot high cube container, supporting bulk orders for commercial procurement.
The air cooler has a 20L unremovable water tank. It can be refilled from the top of the unit without removing the tank.
Yes, the unit includes one remote control as a standard accessory. The remote controls speed settings, oscillation, timer, and the negative ion function.
The air cooler delivers a maximum air flow capacity of 2000 m³/h at a wind speed of 11.5 m/s.
Yes, the negative ion function can be activated or deactivated separately from the cooling function, allowing users to run the cooler with or without the ion feature.
The air cooler is equipped with a 100% copper motor with a power rating of 150W.
