Buying Guide: Key Considerations For Side Draft Swamp Cooler Covers
What size do I need?
Measure your cooler’s width, depth, and height. Choose a cover that fits with a little extra room for ease of installation. If possible, select a model listed as slightly larger than your unit to ensure complete enclosure.
What material is best?
Look for heavy-duty polyester or 600D Oxford cloth that is waterproof and weather-resistant. Durable fabrics resist tearing and provide long-term protection against rain, snow, and debris.
How secure should the cover be?
Consider covers with elastic hems and tie-down straps. Straps prevent wind uplift and keep the cover in place during storms or high winds.
Will it protect against air loss or convection?
Some designs advertise protection against warm air loss and cold air entry. This can help with winterizing and energy efficiency, especially for outdoor installations in varied temperatures.
Are there installation considerations?
Back ropes or tie-downs can simplify installation on side draft units. A slightly looser fit can accommodate variances in model sizes, but avoid excessive slack that allows flapping.
How many units does it fit?
Check the advertised compatibility and confirm your cooler’s dimensions align with the listed size ranges. If you own multiple units, you may prefer a model with a broader size range or multiple size options.
Practical tips for use
- Install before heavy weather for best protection.
- Inspect straps and hems periodically and replace worn components.
- Clean the cover as needed to maintain waterproofing and extend life.
FAQ
- Can I use any side draft swamp cooler cover on my unit?
Only if the size matches. Check width, depth, and height to ensure a secure fit.
- Do these covers require tools to install?
Most models use elastic hems, straps, or ropes and require no tools for basic installation.
- How do I know if the cover is too tight or too loose?
A proper fit should fully cover the unit with minimal slack. If it’s too tight, it may tear; if too loose, wind can cause flapping.
- Can I reuse the same cover for multiple seasons?
Yes, with proper care. Inspect for wear and clean as needed to maintain waterproofing.
Protects against rain, snow, leaves, and wind, but extreme conditions may require additional protective measures or a larger, heavier-duty cover.
