Down Draft Swamp Cooler Covers
1 min read
Rain sitting on top of the unit, or top intake still open? Down-draft cabinets need a wide, low cover with a reinforced top — sides alone are not enough.
Problem: Water Pools or Top Intake Exposed
Down-draft units pull air through the top deck. Sides are mostly solid. A side-draft cover leaves the primary intake open and may sag in the middle — rainwater pools instead of running off.
Solution: Down-Draft Profile + Drainage
- Wide, low cover shape — top panel is the critical seal
- Reinforced top for rain and snow load in open yards
- Tighten straps so the top crowns slightly — water runs to edges, not into louvers
- Confirm outlet duct clearance before ordering — depth must clear roof connections
Open Yard Storage
Add tie-downs on exposed sites. Re-tension after the first storm — a sagging top is the main cause of pooled water and interior rust.
