Description
The WEIYE SEPAT SF-50TDC is a heavy-duty rechargeable evaporative air cooler engineered for off-grid and solar-powered cooling. Equipped with a 24V brushless DC motor, a 200W solar panel capability, and a 40-liter water tank, this unit delivers up to 4,500 m³/h of cool airflow across spaces ranging from 20 to 45 m². The integrated lead-acid battery stores enough energy for extended cordless operation, making it ideal for outdoor patios, workshops, camping sites, and areas with unreliable grid power. Manufactured by Taizhou Weiye Refrigeration Equipment Co., Ltd. — a factory with over 18 years of specialization in evaporative cooling — the SF-50TDC reflects real-world R&D shaped by feedback from distributors in Europe, Africa, the Middle East, and Southeast Asia.
Key Features
Solar + DC Dual Power — True Off-Grid Capability
Runs directly on 24V DC power or through the included 200W solar panel. The built-in 24V 20AH lead-acid battery recharges in 7-8 hours under full sun and provides hours of cooling without any AC outlet. This dual-power architecture eliminates the need for inverters or generators, reducing total system cost for distributors and end-users alike.
Brushless DC Motor — Quiet, Efficient, Long-Lasting
The SF-50TDC is powered by a brushless DC motor that eliminates the friction, sparking, and wear of conventional brushed designs. Without brushes to degrade, the motor runs quieter, draws less power, and lasts 2–3× longer — delivering near-silent operation at low speed, ideal for bedrooms, campsites, and other noise-sensitive environments.
40-Liter Large-Capacity Water Tank
A full 40-liter tank supports continuous cooling for 5-8 hours on a single fill, depending on ambient temperature and fan speed. The tank design includes a wide opening for easy cleaning and an integrated water-level indicator visible from the front panel.
5090 Honeycomb Cooling Pad with Ice Box
The thick 5090-grade honeycomb cooling pad maximizes water-air contact surface area for superior evaporative efficiency. Combined with the large ice box compartment, the unit can drop outlet air temperature by an additional 3–5 °C when ice packs are loaded — a feature particularly valued in Middle Eastern and African markets.
10-Meter Wind Throw Distance
With three adjustable speed settings, the SF-50TDC pushes cool air up to 10 meters. This long throw makes the unit effective in open-plan spaces such as workshops, warehouses, and outdoor dining areas where smaller fans fall short.
PP Body — Corrosion-Resistant and UV-Stabilized
The cabinet is molded from high-grade PP (polypropylene) with UV stabilizers, ensuring resistance to sun exposure, humidity, and light mechanical impact. Available in coffee and white color options to suit different market preferences.

Frequently Asked Questions
Installation & Setup
Setting up the SEPAT evaporative air cooler takes less than 10 minutes and requires no specialized tools or professional installation. Place the unit on a flat, stable surface near an open window or doorway — this is important because evaporative cooling works best with a steady supply of fresh outside air. Fill the water tank through the top or side access port until the water level indicator shows full. If your model includes an ice box compartment, add frozen ice packs for an extra cooling boost. Plug the power cord into a standard AC outlet (for AC models) or connect to the DC power source (for DC/solar models). Select your desired fan speed and activate the cooling pump function. For optimal performance, position the cooler so that the airflow is directed toward the area where people gather, and keep a window slightly open on the opposite side of the room to allow proper air circulation and prevent humidity buildup.
Why Choose SEPAT Over Conventional Air Conditioning
For distributors and commercial buyers, the value proposition of evaporative cooling extends far beyond the purchase price. A SEPAT air cooler typically consumes 100 to 250 watts of electricity — roughly the same as two incandescent light bulbs — while a comparable split-system air conditioner draws 1,000 to 2,500 watts. Over a single cooling season in a warm climate, this difference can translate into hundreds of dollars in electricity savings per unit. Maintenance is equally straightforward: cleaning the water tank and replacing the cooling pad once per season are tasks that any end-user can perform, eliminating the need for costly HVAC service calls. Furthermore, because evaporative coolers contain no refrigerants, they are not subject to increasingly strict environmental regulations on HFCs and HCFCs, making them a future-proof product category for markets with tightening emissions standards. For businesses operating in dry and semi-arid regions — which cover much of the Middle East, Africa, Australia, and the southwestern United States — evaporative cooling is not just an economical alternative but often the most practical solution, as it actually adds beneficial moisture to dry indoor air rather than stripping it away.
How Evaporative Cooling Works
Evaporative air cooling is a natural, energy-efficient process that mimics the cooling effect of a sea breeze. Inside the unit, a water pump circulates water from the tank to the top of a honeycomb cooling pad. As warm outside air is drawn through the wet pad by the fan, the water evaporates, absorbing heat from the air and lowering its temperature by 5–15 °C before it is discharged into the room. Unlike compressor-based air conditioners that recirculate stale indoor air, evaporative coolers continuously introduce 100% fresh, filtered outside air, making them healthier for prolonged use and far cheaper to operate — typically consuming only 10–20% of the electricity of a comparable AC unit. The SF series coolers from Taizhou Weiye enhance this principle with thick 5090-grade cooling pads and powerful motors that maximize evaporative surface area and airflow volume. No refrigerants, no compressor, no closed-loop ductwork — just water, air, and physics.
Q1: What is the Minimum Order Quantity (MOQ) for SEPAT evaporative air coolers?
A: Our standard Minimum Order Quantity (MOQ) for any single model is one 40HQ shipping container (loading quantities generally vary from 140 to 850 units depending on the specific model's chassis and tank capacity). This single-container threshold applies to both our standard SEPAT configurations and customized OEM/ODM production runs. Sample orders for laboratory quality checks are welcomed prior to bulk contract finalization.
Q2: What is your standard B2B production lead time?
A: For standard SEPAT stock configurations, shipment takes 15–20 days. For custom OEM/ODM production runs, shipment occurs within 25–30 days after packaging artwork confirmation and deposit receipt.
Q3: How do you support overseas distributors with aftermarket warranties?
A: We stand behind our quality with a solid 1-Year Comprehensive Warranty on all SEPAT air cooler models. To ensure uninterrupted service in your territory, we ship 1% Free-of-Charge (FOC) essential spare parts directly inside your 40HQ container orders.
Q4: What is the container loading capacity for SEPAT air cooler models?
A: Because our product line ranges in water tank capacity (from 6L to 80L+), the loading quantity per container depends entirely on the specific product dimensions. Typically, one 40HQ container can accommodate between 140 to 850 units. Once you select your desired models, our logistics department will provide a highly optimized, precise container loading layout (Loading List) to maximize your ocean freight efficiency.
