About this item

• 【27dB ULTRA-SILENT】PWM-controlled EC motor delivers 214 CFM of airflow at just 30W — quieter than a whisper, quieter than a library. Perfect for bedrooms, small home offices, nurseries, and bathrooms where silence is essential.
• 【10-SPEED PRECISION CONTROL】The included wired PWM controller gives you 10 precise speed settings — from near-silent air circulation to 214 CFM full-power ventilation. Upgrade anytime to the Toolazy Smart WiFi Controller (sold separately) for app control, scheduling, temperature triggers, and multi-fan sync.
• 【WORKS EVERYWHERE YOU NEED FRESH AIR】Ideal for 2×2 to 4×4 grow tents, hydroponic systems, bathroom exhaust, kitchen ventilation, AV equipment cooling, small workshops, and closets. Creates negative pressure to eliminate odors, control humidity, and circulate fresh air in spaces up to 200 cubic feet.
• 【MIXED-FLOW EC MOTOR TECHNOLOGY】Unlike standard AC motors, the brushless EC motor runs cooler, uses up to 50% less energy, and lasts longer — rated for 40,000+ hours of continuous operation. Mixed-flow impeller design maintains strong airflow even in high static pressure duct systems. Dual ball bearings ensure smooth, maintenance-free performance for years.
