Product Overview
AOSUNFAN 4-inch Inline Duct Fan is designed for hydroponic cultivation, laboratory ventilation and small industrial spaces. It is equipped with EC brushless motor technology (energy consumption is 50% lower than traditional AC motors) and aerodynamic blades, supporting 120-480 CFM air output and noise as low as 32 dB(A) (ISO 4871 standard). It adopts IP55 waterproof and dustproof body (humidity tolerance ≤95%) and corrosion-resistant ABS material, suitable for 4-inch (100mm) duct system, compatible with carbon filter device and smart controller.
Product Features
Silent mixed flow technology
Centrifugal + axial flow hybrid design achieves 20% silent upgrade, dynamic balance impeller vibration value ≤0.5mm/s (ISO 10816-3 certified).
Wireless intelligent linkage
Supports Bluetooth/WiFi dual-mode control (compatible with GrowHub/TrolMaster), and can preset temperature (10-40℃) and humidity (30-90% RH) to trigger speed regulation.
Industrial-grade durable structure
UV anti-aging coating + 304 stainless steel fasteners, resistant to acid and alkali gases (pH 4-10) and dust environments (PM2.5≤200μg/m³).
Quick-release maintenance system
Magnetic front cover design, 5-second removal and cleaning filter, supports water washing and reuse (food-grade silicone seal included).

Product advantages
Extremely long life: double ball bearing motor design, MTBF life up to 80,000 hours (7-year warranty).
Energy-saving certification: Passed ENERGY STAR energy efficiency certification, saving an average of about ¥420 per year (electricity price is ¥0.6/kWh).
Flexible adaptation: horizontal/vertical two-way mounting flange, compatible with round/square pipe interfaces (random adapter ring included).
Safety upgrade: optional explosion-proof version (ATEX Zone 22 certification), suitable for dust/methane high-risk scenarios.
Application scenarios
Home hydroponic box: Maintain uniform distribution of CO₂ in a 1.5x2m planting box (2 ventilations per hour).
Biological laboratory: Exhaust formaldehyde/volatile reagent gas (HEPA filtration efficiency 99.97%).
Micro-processing plant: Remove smoke from laser engraving (best with cyclone dust collector).
Pet room ventilation: Intelligent linkage temperature and humidity sensors to prevent mold growth (RH≤75% threshold).
FAQ
Q1: What are the advantages compared with traditional Inline Duct Fan?
EC motor saves 50% energy consumption, supports APP remote control, and increases filter removal speed by 300%.
Q2: Can it be connected to HomeKit/SmartThings?
It needs to be integrated with a third-party gateway (such as Home Assistant) through the MQTT protocol and supports IFTTT automation scenarios.
Q3: Will it rust under extreme humidity?
The body is sealed with ABS+fluororubber, and the salt spray test passed the 48-hour 5% NaCl solution spray without corrosion.
Q4: Noise performance at minimum air volume?
In night mode (20% speed), the noise level is only 25 dB(A), which is suitable for bedroom-level quietness requirements.
