Description
The WEIYE SEPAT SF-20N is a compact DC solar air cooler built around a lightweight lithium battery system, offering a modern alternative to traditional lead-acid battery coolers. With a 6-liter water tank, a DC brushless motor, and an electronic display panel, the SF-20N delivers up to 1500 m³/h of cooled air across an 10 to 15 square meter area. The integrated 12V 10AH lithium battery is smaller and lighter than equivalent lead-acid units, making the SF-20N exceptionally portable for outdoor activities, camping, and small off-grid spaces. Solar panel compatibility allows the battery to recharge during daylight, extending runtime without grid dependence. The electronic display provides real-time feedback on battery level and operating status, adding a layer of convenience not found in purely mechanical models. Manufactured by Taizhou Weiye Refrigeration Equipment Co., Ltd., the SF-20N represents the company’s continued investment in lighter, smarter cooling solutions for mobile and remote applications.
Key Features
Lithium Battery — Lightweight and Maintenance-Free
The 12V 10AH lithium battery is approximately 60% lighter than an equivalent lead-acid battery and does not require electrolyte refilling or terminal cleaning. It also tolerates deeper discharge cycles without capacity loss, meaning users can run the cooler longer between charges without shortening battery life.
Solar Panel Compatible for Off-Grid Charging
The SF-20N accepts input from a 50–100W solar panel, which recharges the lithium battery in 3–4 hours under full sun. For campers and remote workers, this means the cooler can operate indefinitely during daylight hours and store enough charge for evening use without ever connecting to a wall outlet.
Electronic Display with Battery Level Indicator
A small LED display on the top panel shows current speed setting, battery charge percentage, and operating mode. This real-time feedback helps users plan recharging schedules and avoid unexpected shutdowns during extended outdoor use.
DC Brushless Motor for Quiet, Efficient Operation
The brushless motor generates minimal electrical noise and mechanical vibration, producing a smooth airflow that is comfortable for sleeping and working. The motor’s high efficiency also extends battery runtime, delivering more cooling per watt than conventional brushed designs.
6-Liter Water Tank with Compact Footprint
The 6-liter tank is sized for 2-3 hours of operation and occupies minimal floor space, making the SF-20N suitable for tents, small cabins, and vehicle interiors. The tank slides out for easy filling and cleaning, and an integrated water level sensor prevents the pump from running dry.
ABS Body with Integrated Handle
The UV-stabilized ABS housing includes a built-in carrying handle for easy transport. At approximately 6 kg, the unit is light enough to carry by hand over short distances and fits comfortably in the trunk of most passenger vehicles.

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.
