Product Description

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).
