This is a replacement pad kit for Polar Cool 36" evaporative cooling fans — five CELdek cooling pads, boxed as a set, sized to restore your cooler's water absorption and airflow to like-new condition.
Evaporative cooling pads harden over time as mineral deposits and debris build up on the media surface, reducing water absorption and cooling capacity. This CELdek pad kit is manufactured with an unequal flute design intended to maintain airflow, resist water carryover, and self-clean during operation. 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: 48" H x 12" W x 8" D per pad
- Kit contents: 1 box, 5 pads per box
- Fits Polar Cool 36" fan prop diameter, which uses a 48" tall pad
- Compatible with Polar Cool 36" models and 36" Single Speed fans
- Compatible with Big Ass Fans CoolSpace 400 and Cold Front 400
- Does NOT fit Polar Cool 36" Pro series
- Does NOT fit Polar Cool 36" Zone series
- Does NOT fit older 36" units that use 6" thick pads (those require SKU 6450-6014)
- Verify pad size and quantity against your unit's original pad configuration before ordering
Pad thickness mismatches are the most common return on evaporative cooler media — a 6" pad forced into an 8"-deep frame channel will bow, restrict airflow, and shed media fibers into the fan housing. Before you pull the old pads, measure the depth of the frame channel itself, not just the fan prop diameter, since some older 36" chassis were built for 6" pads even though the fan size matches. Confirm depth with a tape measure at two points on the frame (top and bottom channel can differ slightly on older units). This matches general ASHRAE guidance on maintaining manufacturer-specified media clearances to prevent uneven water distribution and premature pad failure.
Key Benefits
- CELdek unequal flute design supports high face velocity without water droplet carryover
- Self-cleaning flute geometry flushes dirt and debris toward the water-entry face
- Low pressure drop design maintains airflow efficiency
- Algae-resistant treated substrate; optional MI-T-edg edge coating available for extended weather and UV exposure life
- GREENGUARD Gold certified for low chemical emissions, suitable for indoor air quality-sensitive spaces
- Routine maintenance can be performed while the system is still running

FAQ
What size are the pads in this kit?
Each pad measures 48" H x 12" W x 8" D. This kit includes 1 box containing 5 pads.
Will this fit any Polar Cool 36" fan?
It is engineered for Polar Cool 36" models, including 36" Single Speed fans, but it excludes the Pro and Zone series. It is also compatible with Big Ass Fans CoolSpace 400 and Cold Front 400.
My older 36" unit uses thicker pads — will this kit work?
No. Some older 36" units use 6" thick pads, which require SKU 6450-6014 instead of this kit.
Can I buy a single pad instead of a full kit?
Yes. A single pad is available under SKU 6450-6068. A larger case of 6 boxes (30 pads total) is available under SKU 6450-6069.
Are these pads treated for algae and mineral resistance?
Pads are available with optional MI-T-edg edge protection, a nonporous, quick-drying coating that resists algae and mineral buildup and adds UV resistance. Base pads use an algae-resistant treated substrate.
