This is a replacement pad kit for PolarCool 36" Pro evaporative coolers — four CELdek cooling pads sized for units that use a 48" tall pad. It's for anyone whose swamp cooler airflow or cooling has dropped off because the old pads have hardened with mineral scale.
PolarCool builds these pads from CELdek media with an unequal flute design, which lets air pass through at high velocity without pushing water droplets into your living or work space. As pads age, mineral deposits and debris harden the media and reduce water uptake — replacing them restores both cooling capacity and airflow. 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
- Each pad: 48" H x 12" W x 6" D — 4 pads per box, engineered for units with a 36" fan prop diameter that require a 48" tall pad.
- Fits PolarCool 36" Pro models and PolarCool Zone 11K (36" gray rotomolded plastic).
- Fits PolarCool 36" single speed and older direct drive models.
- Does NOT fit 36" units that use 8" thick pads — those require SKU 6450-6010.
- Does NOT include a single-pad option — for one pad only, order SKU 6450-6070 separately.
- Verify pad size and quantity against your unit's original pads before ordering; PolarCool notes this explicitly for this model line.
Key Benefits
- CELdek media construction rated for high face velocity without water droplet carryover.
- Self-cleaning unequal flute design flushes dirt and debris from the pad surface.
- Algae-resistant treated substrate for extended service life.
- Low pressure drop design supports airflow without added fan strain.
- GREENGUARD Gold certified for low chemical emissions, suited to indoor air quality-sensitive spaces.
- Optional MI-T-edg edge coating available for added UV and weather resistance on treated pads.

FAQ
What size are these pads?
Each pad measures 48" H x 12" W x 6" D. The kit includes 4 pads in one box.
Will this fit my PolarCool Zone 11K cooler?
Yes. This pad kit is compatible with the PolarCool Zone 11K (36" gray rotomolded plastic model), as well as PolarCool 36" Pro models and older 36" single speed/direct drive units that use a 48" tall pad.
Does this fit 36" units with 8" thick pads?
No. Some 36" units use 8"-thick pads instead of the 6" depth in this kit. Those units need SKU 6450-6010, not this kit.
Can I buy just one pad instead of the full set of 4?
Yes. A single pad is available separately under SKU 6450-6070. This listing (6450-6014) is the full set of 4 pads in one box.
Are these pads treated for algae or UV resistance?
The pads use a self-cleaning unequal flute design and an algae-resistant substrate. An optional MI-T-edg edge treatment is available on some CELdek pads for added UV and mineral resistance at the air-entering face.
