Key Features
4,500 m³/h Powerful Cooling Output
The SF-50M's AC motor drives a large-diameter fan delivering up to 4,500 m³/h of cool, humidified air. This airflow is sufficient to circulate fresh air through open-plan living rooms, mid-sized workshops, and outdoor dining areas, making the unit a versatile performer across multiple application types.
40-Liter Water Tank
A full 40-liter tank provides 5-8 hours of continuous evaporative cooling on a single fill. The tank features a wide-mouth opening for easy manual filling with a bucket or hose, and a front-facing water level gauge allows users to check remaining water at a glance.
Simple Mechanical Rotary Control
A rotary knob control panel with clearly marked positions for Off, Low, Medium, High, and Pump activation ensures operation is intuitive for any user. No digital displays, no remote controls to lose — just turn the knob and get cool air. This mechanical simplicity translates to higher reliability and fewer after-sales service issues.
PP Cabinet — Weather-Resistant Construction
The one-piece PP (polypropylene) injection-molded cabinet is inherently resistant to water, humidity, and UV exposure. Unlike metal-bodied alternatives, the SF-50M will not rust or corrode even in coastal or high-humidity environments, extending its usable life in challenging climates.
Efficient Evaporative Cooling Pad
The thick honeycomb cooling media provides maximum surface area for water-to-air heat exchange. Combined with an efficient water distribution pump, the cooling pad achieves a 10-15 °C temperature reduction under favorable conditions (dry heat), providing meaningful relief without the energy cost of compressor-based air conditioning.
Four Casters for Easy Mobility
Four swivel casters allow smooth movement across tile, concrete, and wooden floors. At approximately 14.1 kg net weight, one person can easily reposition the unit between rooms or from indoor to covered 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.
