YOOTU Technology: The "Soul Accessory" of Air- Conditioned Vests: This Fan Turns Hot Days into "Cool Mode"

The "Heart" of Air-Conditioned Vests: Determines 80% of Cooling Effect Think the core of air-conditioned vests is the clothing? Wrong! What really keeps you dry in 40℃  heat are the two brushless fans on the back. Like the "heart" of the vest, they push rated revolution airflow per second, turning stuffy work environments into a cool environment.

Why This Fan Can "Fight Heatwaves"?

1. Brushless Motor: Quiet & Durable

5000 rated revolution: 3 times faster than ordinary fans, quickly drawing in cool air and expelling hot air from the vest;

Noise < 40dB: Equivalent to quiet conversation, barely audible in noisy environments like construction sites/ roads;

Lifespan > 5000 Hours: Used 8 hours daily, lasts 2 years-3 times more durable than regular fans. 

2. Five- Blade Design: stronger wind, more even cooling

FIve amber blades(as shown) boost wind power by 40% vs traditional three-blade fans;

Unique "air guide grooves" distribute wind to the chest, back, and waist "not cool in one spot, stuffy elsewhere."

3. Detachable & Washable: No more " Dusty Fans Blowing Hot Air"

Fan cover twists off

Clean blades/ grilles weekly with a soft brush to avoid dust blockage.

Installation & Use: 3 steps to Instant Cooling

Step 1: Align with Vest's Fan  Slot

Find the circular "fan slot" on the vest's back, align the fan's

Step 2: Twist to Secure

Rotate clockwise until your hear a "click" (as shown in installation diagram).

Step3: Plug in Power Bank, Adjust Speed

Connect fan wires to the inner adapter, plug into a power bank (type-c/USB-A compatible);

Press the vest's "speed button" to switch low-medium-high (stronger wind)

Usage Scenarios 

Construction Sites: No dizziness when tying rebar, Medium speed and riding airflow creates " convection cooling"- no heat rashes after all day delivery.

Outdoor Workers: No sticky uniforms. Medium speed keeps core areas cool during traffic directing/ street sweeping-flexible movements.

Three Tips to Extend Fan Life

1. Weekly Cleaning: Use a soft brush or hairdryer (cool setting) to remove dust form blades/grilles.

2. Avoid Rough Handing: Fan wires/ adapters are fragile-handle gently when plugging/ unplugging.

3. Long-Term storage: Remove fans, store in a ventilated, dry place to prevent motor rust.

This summer, don't let heat damage your health or blur you vision. Equip your air-conditioned vest with this " soul fan" for lasting coolness and dignified work.

This summer: work comfortably!
