Control Panel

Simple upkeep and easy-to-operate rotary controls make controlling this air cooler a snap.

Motor Speed Dial: Turn on the cooler and select your fan speed between Low, Medium, and High with the fan switch.
Pump: Switch the pump on to saturate the internal Cooling Media.
Air Swing Delivery System: Turn the swing switch on or off for automatic oscillation.

Manual and Continuous Fill Options

Flexible water fill options are available to you when you have the swamp cooler indoors or outside near a garden hose.

Manual Fill: Push on the spring-loaded front fill door for manual fill into the 10.3-gallon tank. Monitor water volume through the water level indicator. When the water limit hits “FULL,” start the internal water pump.
Continuous Fill: Assemble the continuous fill garden hose float adapter to the swamp cooler during assembly. The continuous fill method allows for a simple garden or coil hose connection that eliminates the need to manually watch and fill the water tank.

Powerful Airflow

Cooling the air is only a part of the process; propelling the chilled air into your space is what brings you needed relief. Specially engineered features from Hessaire allow this mobile evaporative cooler to provide an airflow of 3,100 CFM to your area:

The cupped axial fan design allows it to not only provide a strong airflow to thrust chilled air into your space.
The air swing delivery system moves cool air left to right across the room to ensure that air is evenly distributed.
The Axial fan can be adjusted between three fan speeds: Low, Medium, and High.

Additional Features

Fan-Only: Use the swamp cooler on one of the three fan speeds without water just to propel air throughout a stuffy room.
Cup Holder: The top cup holder is a great resting place for drinks.
Palm Design: Unique palm grill design provides an organic design.
Optional Cover: For additional protection, check out Hessaire’s MC37/M150 Evaporative Cooler Cover. This durable cover features the Hessaire logo and provides rugged protection for the cooler.
