Our evaporative coolers pull fresh outdoor air through water-saturated media, dropping supply-air temperatures by up to 30°F while using only a fraction of the power of traditional DX systems. Whether you need to keep a garage comfortable or tame midsummer heat in a manufacturing bay, Snook & Aderton carries the right capacity, configuration, and brand.
Unlike compressor-based AC, swamp coolers work best in the low-humidity zones that define much of the American Southwest and Mountain West. Choose from compact window units , heavy-duty side-draft and down-draft cabinets , or portable coolers on rugged casters.

Top Brands in This Collection FAQs What size evaporative cooler do I need? Match airflow to your space: roughly 2 CFM per square foot. A 5,000 CFM unit covers about 1,600 sq ft.
Do these coolers add too much humidity indoors? They raise the relative humidity by 2–5%, ideal for dry climates. Use adequate exhaust (open doors/windows) for best comfort.
Can I run an evaporative cooler in a garage with the door closed? You’ll need an exhaust opening (e.g., cracked window or roof vent) to allow warm air to escape and maintain airflow.
How often should pads be replaced? Aspen pads: annually; rigid media: every 3–5 years, or sooner if minerals accumulate.
Do you stock replacement pumps and motors? Yes—visit our evaporative cooler parts page for pumps, bearings, belts and controls that ship same-day.
