This is a replacement pad kit for PolarCool 18" evaporative cooling fans — two CELdek media pads per box, sized to restore proper airflow and cooling efficiency once your old pads harden up from mineral buildup.
These CELdek pads use an unequal flute design that pulls water to the air-entering face while flushing dirt and debris off the surface — a self-cleaning action that keeps cooling efficiency consistent between service intervals. Built for portable evaporative coolers and spot-cooling applications, they're a direct genuine replacement for PolarCool 18" fan models. Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
Critical Fitment & Requirements
- Pad dimensions: 36" H x 12" W x 8" D (each pad)
- Kit includes 2 pads per box
- Engineered for PolarCool 18" fan/prop diameter models only
- 18" fan prop diameter corresponds to a 36" tall pad — this is the correct pad height for that fan size, not an arbitrary spec
- NOT engineered for PolarCool models with a different fan prop diameter than 18" (those use different pad heights)
- Verify both pad size and quantity needed for your unit before ordering
Key Benefits
- CELdek media construction for high cooling efficiency and low pressure drop
- Self-cleaning unequal flute design flushes dirt and debris off the pad surface
- Specially treated, algae-resistant substrate engineered to resist deterioration
- GREENGUARD Gold certified for low chemical emissions and VOCs
- Optional MI-T-edg edge protection resists algae/mineral anchoring and UV/weather degradation
- Maintenance can typically be performed while the system is still operating

| Optional Edge Treatment | MI-T-edg — nonporous, quick-drying, algae-resistant, UV/weather resistant edge coating |
FAQ
Will this pad kit fit any PolarCool cooler?
No. This kit is engineered specifically for PolarCool 18" models — units with an 18" fan prop diameter that use a 36" tall pad. Confirm your unit's fan prop diameter before ordering.
What size are the pads in this kit?
Each pad measures 36" H x 12" W x 8" D. The kit includes 2 pads in one box.
How many pads come in the box?
One box contains 2 pads, sold as a set for one PolarCool 18" unit.
Do these pads have any air quality certifications?
Yes. These CELdek pads are GREENGUARD Gold certified, meeting low chemical emission and VOC criteria suitable for sensitive indoor environments.
How do I know if I need to replace my pads?
Over time, mineral and debris buildup hardens evaporative pads, reducing water absorption and cooling power. New pads restore full water-holding capacity and evaporative cooling effect.
