The Model 48R outdoor evaporative air cooler is designed for industrial applications including warehouse facilities, construction site offices, outdoor event venues, and agricultural operations. Using evaporative cooling technology, this unit draws warm air through moistened cooling pads and discharges cooled air into the surrounding space.
The unit generates a maximum airflow of 2000m³/h with a wind speed of 6m/s at the outlet, measured at the highest fan setting. Three fan speed settings (low, medium, high) allow adjustment based on cooling requirements and ambient conditions. The motor is constructed with 100% copper winding.
Automatic left-right louver oscillation distributes airflow across a wider area, while manual up-down angle adjustment lets operators direct cooling toward specific zones. Under test conditions of 35°C ambient temperature and 50% relative humidity, the unit provides noticeable temperature reduction within a coverage area of approximately 50-70 square meters, depending on ceiling height and space configuration.
Evaporative coolers operate most effectively in dry climates with relative humidity below 60%. In higher humidity environments, the units still provide air movement and ventilation benefit, though temperature reduction is proportionally lower.
The 20L water tank supports continuous operation for up to 10 hours on a single fill when operating at low fan speed under standard test conditions (25°C, 50% RH). Runtime decreases at higher fan speeds and in drier ambient conditions due to increased evaporation rate.
A 9-hour programmable timer allows users to set automatic shut-off in advance, supporting scheduled cooling periods and overnight operation. A drain plug at the tank base simplifies water replacement and routine cleaning. The cooling pads are detachable for periodic washing.
Adding ice cubes to the water tank can lower the output air temperature by an additional 2-3°C, though this reduces the total runtime per tank fill due to faster water consumption.
The body is constructed from ABS plastic with UV-resistant treatment, suitable for outdoor and industrial environments. The front grille is made of rust-resistant metal. Four heavy-duty castor wheels (two with brake locks) enable mobility across flat surfaces.
An integrated anion function releases negative ions into the airflow. The unit holds CB certification. Top-mounted power cord storage keeps the cable organized when the unit is not in use.

This air cooler is deployed across a range of industrial and commercial settings including factory floors, warehouse staging areas, construction site offices, outdoor event seating zones, greenhouse ventilation, and livestock shelter cooling. For procurement managers evaluating evaporative cooling solutions, the unit offers a balance of airflow capacity, tank size, and mobility features.
Bulk orders are shipped in individual gift boxes with remote control and castor accessories included. Full container loading specifications are listed in the technical specifications table for logistics planning. Custom branding on the body or packaging is available with minimum order quantity requirements.
Evaporative cooling is most effective in dry environments where relative humidity stays below 60%. In areas with higher humidity, the unit still provides air circulation and ventilation, but the temperature drop is reduced. Performance data across humidity ranges can be provided for evaluation purposes.
Cooling pad cleaning is recommended every 2-4 weeks under normal use. In areas with hard water or high mineral content, more frequent cleaning prevents mineral buildup and maintains cooling efficiency. The pads are detachable for easy access.
Yes, ice cubes may be added to the water tank to lower output temperature by approximately 2-3°C. Note that adding ice reduces the total runtime per fill because water is consumed at a faster rate.
The unit operates at 120W and is compatible with 110-240V power supplies. It can be used with standard wall outlets or with generators and inverters of appropriate capacity for off-site or mobile applications.
