SPT 101-Pint Heavy-Duty Evaporative Cooler  – SF-48LB

This powerful, commercial Evaporative Air Cooler is the perfect choice to effectively cool large areas. Air coolers do not use compressors, which means no harsh chemicals and low energy consumption. This air cooler features 1062 CFM and 3-sided air vents with honeycomb cooling pad for maximum airflow. Offers the option to connect to standard garden hose for continuous water supply and eliminate the trouble of manual refill. Equipped with easy-roll casters, the unit can be moved and used where ever it’s needed. For patio use, avoid water and rain exposure. When not in use, unplug the unit from the power socket and store it indoors.

The Air Cooler works by endothermic reaction (a reaction that consumes heat), so this evaporative Air Cooler sucks air through a wick saturated with water.
As the air flows through the wick, some of the water evaporates into the air, consuming the heat that was in the air. An air stream is then blown out the front of the unit and is considerably cooler than the current room temperature! This is not an air conditioner and therefore uses much less energy.

3-Dimensional Honeycomb Cooling Pad: An unique Cooling Pad for enhanced cooling performance. The Cooling Pad is made of cellulose paper, impregnated with unique ingredients for high performance and structural strength. Treated with special stiffening and wetting agents for maximum water absorption and retention; and with Anti-Rot chemical for prevention of algae and bacteria growth. Due to the 3-dimensional, weaving structure of the Cooling Pad, there is longer contact between air and water. Unlike other units on the market, where air only passes through a flat, 2-Dimensional cloth.

Note: This unit is NOT an air conditioner and does not have a compressor inside – air coolers will not lower a room’s ambient temperature. Air coolers are designed for spot cooling. This unit is best used in dry climates with low humidity or open spaces. When used indoors, leave window/door open to limit the rise of humidity and for better air ventilation in the room.

Maintenance Tips

• Clean the Water Tank Weekly: Empty and rinse the water tank regularly to prevent mold, mildew, and mineral buildup.

• Inspect and Rinse Cooling Pads: Check the honeycomb pads monthly and rinse with clean water to maintain efficient cooling performance.

• Check Water Level and Refill as Needed: Keep the tank filled or ensure the garden hose connection is secure for continuous operation.

• Clean Exterior and Air Vents: Wipe down the unit and keep the 3-sided vents dust-free for optimal airflow.

• Drain and Dry Before Storage: If not in use for an extended period, completely drain, clean, and dry the cooler to prevent odors and damage.

• Clean Float Valve: Ensure the float valve (if hose connected) operates correctly to prevent overflow or underfilling.

• Use Clean Water Only: Always use clean water to reduce scaling and increase pad lifespan.

• Inspect Casters: Periodically check the caster wheels for smooth movement and secure attachment.
