WEIYE SEPAT SF-35T Portable air Cooler Ac Air Cooler Freestanding Evaporative air Cooler
Description
The WEIYE SEPAT SF-35T is a freestanding evaporative air cooler built for homes, shops, and light commercial spaces that need reliable spot cooling without the cost or complexity of traditional air conditioning. Powered by standard AC mains, the unit combines a 30-liter water tank with a high-output fan capable of moving 4000 m³/h of air across an area of 15 to 30 square meters. With three selectable speed levels and straightforward mechanical controls, the SF-35T offers an accessible, low-maintenance cooling solution that anyone can operate. At approximately10.6 kg net weight, it is easy to move between rooms or position near workstations, checkout counters, and seating areas. Manufactured by Taizhou Weiye Refrigeration Equipment Co., Ltd., the SF-35T reflects the same engineering standards that have made SEPAT products a recognized choice in more than 16 export markets.
Key Features
30-Liter Water Tank for Extended Cooling
The generous 30-liter tank supports continuous operation for 6–10 hours on a single fill, depending on ambient temperature and selected fan speed. A wide fill opening and front-mounted water level indicator make refilling and routine cleaning straightforward, reducing downtime during busy work hours or hot summer afternoons.
4000 m³/h Airflow with 3 Speed Settings
The high-efficiency axial fan delivers up to 4000 m³/h of cooled air across three speed settings. Low speed provides quiet background cooling suitable for bedrooms and small offices, while high speed rapidly reduces perceived temperature in workshops, retail floors, and outdoor patios.
Mechanical Control — Simple and Reliable
A rotary mechanical control panel selects fan speed and activates the cooling pump. Without digital displays or complex menus, the interface is intuitive for all users and remains functional in dusty or humid environments where electronic panels may degrade over time.
PP Body — Lightweight and Corrosion-Resistant
The housing is molded from UV-stabilized polypropylene (PP), a material chosen for its resistance to moisture, mild chemicals, and daily impact. The lightweight construction keeps the unit at approximately 10.6kg, allowing one person to lift and reposition the cooler without assistance.
Freestanding Design with Castor Mobility
Four sturdy castor wheels and a compact footprint let the SF-35T roll across flat floors, tile, and concrete. The freestanding form factor means no wall mounting, ductwork, or professional installation is required — simply fill the tank, plug in, and cool.
Efficient Honeycomb Cooling Pad
The unit uses a high-density honeycomb cooling pad to maximize the water-air contact surface, improving evaporative efficiency and producing a larger temperature drop at the outlet. The pad is accessible for seasonal cleaning and replacement, helping maintain cooling performance year after year.

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 Warrantyon all SEPAT air cooler models. To ensure uninterrupted service in your territory, we ship 1% Free-of-Charge (FOC) essential spare partsdirectly 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 140to 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.
