Replacement aspen swamp cooler pads for stand-alone evaporative coolers will keep your greenhouse or warehouse from buckling under the summer heat. Aspen pads offer the best cooling capacity and water absorption but eventually wear out. Depending on water quality, frequency of use and environmental conditions, swamp cooler aspen pads generally should be replaced every three to four years, though some commercial growers will need to change them more often. These OEM evaporative cooler pads are easy to install so the system will quickly be humming again.

Greenhouse Megastore has eight different swamp cooler padding kits for our ducted and thru-wall evaporative cooler models. See the chart below for which aspen pad set goes with which swamp coolers. Order them for scheduled maintenance or keep a backup set on hand in case of emergencies. If you don't see your model listed or have questions about installation, call us at 888-281-9337. We're here to help with the right swamp cooler filters for better performance.

Great product
Size: 19inch
Excellent quality! Highly recommend. I love that you can wheel it around to other areas and the wheels lock in place.

Good umbrella stand
Size: 21inch
Works really well. I filled it with water and it works great. The wheels worked great on the pool deck. The umbrella stands upright even in the wind here in Florida. Worth the price. Multiple pole size inserts. 2 pole security screws.

As Advertised
Size: 19inch
The product seems well constructed and rolls easily when wheels are unlocked, even with full weight. Had windy conditions recently and the umbrella was held steady.

Seems like a good product, could use a couple improvements...
Size: 19inch
Product seems fine so far, and the adjustable size for the pole is good. Areas for improvement are a larger fill valve so you could fill sand with something other than a teaspoon. Also would have been better if all four wheels had locks and not just two.

Holds 100 pounds of water
Size: 19inch
Some assembly required. Rolls easily in direction of wood grain on a deck. Very difficult to roll sideways across gaps in deck boards.
