WEIYE SEPAT SF-20T Portable air Cooler Ac Air Cooler 20L Water tank Evaporative air Cooler for Home Shop and Camping
Description
The WEIYE SEPAT SF-20T is a compact AC evaporative air cooler designed for personal and small-space cooling in homes, shops, and outdoor recreational settings. With a 20-liter water tank and an airflow rating of 3000 m³/h, the SF-20T covers 10 to 25 square meters efficiently, making it ideal for bedrooms, small retail counters, and camping tents. At approximately 10.2 kg net weight, it is the lightest unit in the SEPAT range, and its small footprint allows it to fit comfortably in tight spaces where larger coolers would be impractical. Three speed settings and mechanical controls keep operation straightforward, while the ABS body ensures durability without adding unnecessary weight. Whether used as a primary cooling source in a compact apartment or as a supplementary fan in a workshop, the SF-20T delivers reliable evaporative cooling at low operating cost.
Key Features
Ultra-Compact Design for Small Spaces
Measuring well under one meter in height and with a narrow base, the SF-20T fits into corners, under tables, and beside beds without obstructing walkways. This compact form is especially valued in studio apartments, small shops, and camping setups where every square meter matters.
20-Liter Water Tank for 7-10 Hours of Cooling
The 20-liter tank is sized for half-day operation and features a quick-fill side opening that accepts water jugs and hoses. A water level indicator on the front panel lets users know when a refill is approaching, preventing unexpected interruptions during sleep or work.
3000 m³/h Airflow with 3 Speed Settings
The AC motor drives a balanced fan to produce 3000 m³/h of airflow across low, medium, and high speeds. Low speed is quiet enough for overnight bedroom use, while high speed delivers a strong cooling breeze for active daytime environments such as shop counters and workstations.
Mechanical Control — No Learning Curve
A simple rotary knob selects fan speed and activates the cooling pump. There are no digital menus, remotes, or app connections to configure. This design makes the SF-20T immediately usable by anyone, including elderly users and children, without technical assistance.
Lightweight ABS Body at ~10.2 kg
The ABS housing keeps the unit at approximately 10.2 kg, light enough for one person to carry up stairs, load into a vehicle, or transport to a campsite. Despite its light weight, the ABS material is impact-resistant and does not corrode, making it suitable for both indoor and covered outdoor use.
Low Power Consumption for Energy Savings
Drawing approximately 80–100 watts depending on speed, the SF-20T consumes a fraction of the electricity used by compressor-based air conditioners. For users in regions with high electricity costs or limited grid capacity, this low power draw translates to meaningful savings over a cooling season.

Manufacturing & Quality Assurance
Taizhou Weiye Refrigeration Equipment Co., Ltd. has specialized in home appliances - including evaporative air coolers and electric heaters - since 2007. Operating from a 10,000+ m² production facility with four active assembling lines and approximately 120 skilled employees, the factory maintains a daily output capacity of 1,500 to 2,000 units and ships products to over 16 countries across Europe, North America, South America, Southeast Asia, the Middle East, and Africa.
Every unit undergoes a full QC inspection before shipment, including motor performance testing, water tank leak testing, battery charge/discharge cycling, and cooling efficiency verification. The factory holds ISO 9001 quality management certification, and SEPAT-brand products have passed CCC, CE, FCC, CB, ROHS, and PSE certifications - backed by over 47 patent certificates - meeting safety and performance requirements for diverse international markets.
OEM and ODM services are available. Buyers can customize body color, branding, packaging, and select optional accessories to match local market requirements.
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.
