Product Overview
The AOSUNFAN 6-inch Exhaust Fan (Model AF-6WS) is a humidity-sensing ventilation solution designed for high-moisture environments like bathrooms, kitchens, and laundry rooms. Featuring an auto-adjusting shutter system (with anti-backdraft damper) and integrated humidity sensor (10–90% RH detection range), it removes 95% airborne moisture within 20 minutes (ASHRAE 62.2 compliant). The ABS+PP polymer housing (IP55-rated) and dual-ball-bearing EC motor deliver 50–380 CFM airflow at ≤35 dB(A), with ENERGY STAR-certified efficiency (1.2 W/CFM). Compatible with 6" ducts and smart home systems via Z-Wave/Zigbee.
Product Features
Smart Humidity Response
Auto-activates at 65% RH (±5% accuracy) and shuts off after 10 dry minutes, preventing mold growth (tested per ASTM D6329).
Zero-Leakage Shutter
Spring-loaded aluminum shutters with silicone seals block 99% reverse airflow, even in 15 m/s winds (tested in HVAC wind tunnel).
Ultra-Quiet Operation
Noise-optimized blades + rubber dampeners reduce vibration by 40% vs. standard fans (ISO 3744-certified).
All-Weather Durability
UV-stabilized housing withstands -30°C to 80°C, ideal for coastal/industrial zones (salt spray resistance per ASTM B117).

Easy Installation: Pre-drilled mounting holes fit standard 6"–8" wall cavities; includes foam gasket and duct collar.
Low Maintenance: Grease-proof blade design + removable nylon filter (washable, 200+ cycles).
Safety Certified: ETL/CE listed for wet locations (NEMA 4X enclosure rating).
Application Scenarios
Bathrooms: Eliminates condensation in 20m² spaces (4–8 air changes/hour).
Commercial Kitchens: Reduces grease buildup with 130°C heat-resistant blades.
Garage Workshops: Vents paint fumes/VOCs (compatible with activated carbon filters).
Pet Salons: Controls dander and humidity (tested with 30mg/m³ allergen levels).
FAQ
Q1: How does this compare to standard bathroom fans?
This Exhaust Fan offers 3x faster moisture removal (380 CFM vs. 100 CFM) and 50% quieter operation, with auto-humidity tracking for precision ventilation.
Q2: Can it operate in freezing temperatures?
Yes, the motor has built-in thermal protection for -30°C environments (defrost cycle activates at 0°C).
Q3: Is the humidity sensor adjustable?
Customize activation thresholds via the control panel (50–90% RH in 5% increments).
Q4: Warranty coverage for damp environments?
5-year warranty covers corrosion and motor failure in humidity ≤95% (excludes saltwater exposure).
