WEIYE SEPAT SF-25TDC Hot Selling Portable AC/DC Evaporative Cooling Fan Solar-Powered New Plastic Desert Air Conditioner for Outdoor
Description
The WEIYE SEPAT SF-25TDC is a versatile AC/DC evaporative cooling fan designed for outdoor environments where access to mains power is limited or unavailable. This compact unit operates on standard 230V AC power indoors and switches seamlessly to 12V DC or solar power for off-grid use in the field. A 20-liter water tank and a DC brushless motor deliver 2,500 m³/h of cooled air across a 10 to 15 m² area, making it suitable for small outdoor gatherings, construction site rest areas, and remote cabins. The built-in 12V 30AH lead-acid battery stores energy from an optional solar panel, providing hours of cordless cooling when the sun is shining. With a durable ABS body and a lightweight form factor, the SF-25TDC is built to travel.
Key Features
AC/DC Dual Power with Solar Compatibility
The SF-25TDC accepts both 230V AC and 12V DC input, giving users flexibility to plug into a wall socket or run directly from a battery or solar panel. This dual-power design is particularly useful for regions with intermittent grid supply, where the unit can charge during stable hours and continue cooling on battery when power cuts occur.
12V 30AH Lead-Acid Battery for Cordless Operation
The integrated 12V 30AH lead-acid battery provides 8-25 hours of continuous cooling on a full charge. When paired with a solar panel, the battery recharges during daylight hours, creating a self-sustaining cooling loop that requires no external power source after initial setup.
DC Brushless Motor — Efficient and Quiet
A DC brushless motor drives the fan with minimal electrical loss and reduced mechanical noise compared to conventional AC motors. The brushless design also eliminates carbon brush wear, extending motor life and reducing maintenance requirements for users in remote locations where spare parts may be difficult to source.
20-Liter Water Tank with Easy Access
The 20-liter tank is sized for 4–7 hours of continuous operation and features a wide-mouth fill port for quick refilling from buckets or hoses. An integrated water level window on the front panel lets users monitor remaining capacity without opening the unit.
ABS Plastic Body for Outdoor Durability
The cabinet is molded from impact-resistant ABS with UV stabilizers to resist sun damage and fading. The material withstands the temperature swings and dust exposure common in desert and semi-arid climates, making it a practical choice for outdoor markets in the Middle East and Africa.
Compact and Portable Form Factor
Weighing approximately 9.8 kg, the SF-25TDC is one of the lighter units in the SEPAT lineup. A built-in handle allows one person to move the cooler across uneven ground, transport it in a vehicle, or reposition it between indoor and outdoor spaces.

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.
