This combo pairs the PolarCool Pro 36" evaporative cooling fan with a 90-gallon water cart, giving you a portable, high-airflow cooling system that can run all day without a hose hookup — built for job sites, warehouses, and outdoor events where a direct water line isn't available.
Field crews and facility managers reach for this combo when there's cooling to be done and no water line to plug into. The PolarCool Pro 36" pairs a rotationally molded reservoir with a 90-gallon gravity-fed water cart, extending runtime well past what the fan alone can deliver — a practical fit for open warehouses, loading docks, and outdoor events.

System Components
- PolarCool Pro 36" Evaporative Cooling System (Model #6622-6000) — axial fan with galvanized steel housing and black powder coat finish
- Edge-coated evaporative cooling media, treated with an algae-resistant substrate for extended pad life
- 38-40 gallon rotationally molded internal reservoir on the fan (rust- and leak-resistant plastic)
- PolarCool 90-Gallon Water Cart (Model #6540-1809) — all-metal frame, black powder coat finish, 750 lb full-load capacity
- 6 heavy-duty casters on the cart (2 stationary, 2 swivel with locks) plus a push/pull handle with tugger loop
Installation Requirements & Accessories
- Fan requires a 120VAC outlet; 20-foot GFCI-protected power cord included, drawing 8.5A (10A at 115V, 60 Hz)
- Water cart connects to the fan via a 4-foot hose with quick-connect fittings for fast attach/detach during refills
- Cart is gravity-fed — no pump, no electrical connection required for the cart itself
- Not recommended for enclosed spaces without cross-ventilation
- Direct continuous water-line hose connection is NOT included or supported — this is a reservoir/cart-fed system only
- No additional accessories required beyond what ships with each unit
Pro-Installer Tip
Evaporative cooling only works if the space can exchange the humid air the process creates — position this combo near an open bay door, loading dock, or window to keep fresh air moving through. Without that cross-ventilation, humidity builds up indoors and cooling output drops noticeably. On the maintenance side, refill the water cart before it runs dry and rinse the reservoir periodically to limit mineral scale and algae growth in the pads — the edge-coated media resists algae but still benefits from clean water and routine checks. As a general rule, this system performs best in relative humidity below 60%; in muggier conditions, expect reduced cooling effect regardless of airflow.
Key Benefits
- 10,000 CFM airflow with 10-speed variable control for precise adjustment
- Rated for cooling areas up to 3,000 square feet
- Combined 38-40 gallon fan reservoir + 90-gallon cart for up to 10+ hours of runtime without refilling
- Fully portable — no water hookup or fixed installation needed
- Gravity-fed cart delivery means no added pump or electrical draw for the water supply
- Quick-connect hose system lets you detach the cart for refilling without stopping cooling operation

FAQ
Does this unit require a continuous water connection?
No. The PolarCool Pro 36" has a 38-40 gallon internal reservoir, and this combo adds a 90-gallon gravity-fed water cart, so the system can run for extended periods without a direct water-line hookup. It does not include a fitting for continuous hose supply from a building water line.
How large of a space will this evaporative cooler effectively cool?
The PolarCool Pro 36" moves up to 10,000 CFM and is rated to cool areas up to 3,000 square feet, depending on relative humidity, temperature, and how well-ventilated the space is.
Can this be used indoors without open windows?
It is not recommended in enclosed spaces without cross-ventilation. Evaporative cooling depends on moving fresh air through the space; without an air exchange path, humidity builds up and cooling performance drops.
What kind of power outlet is required?
The PolarCool Pro 36" runs on 120VAC with a GFCI-protected 20-foot power cord, drawing 8.5A (10A at 115V, 60 Hz). It is compatible with standard GFCI-protected outlets. The 90-gallon water cart has no electrical requirement — it operates on gravity feed.
How long can this system run before needing a refill?
Combined, the fan's 38-40 gallon internal reservoir and the 90-gallon water cart provide up to 10+ hours of continuous cooling without refilling, at a water consumption rate of about 12 gallons per hour in temperatures at or above 90°F.
