DOOA Circulation Fan 40

DOOA Circulation Fan 40

A drip-resistant 40mm fan engineered specifically for DOOA System Paluda side-hole mounting. The Circulation Fan 40 provides precise airflow control to tune humidity levels and distribute Mistflow mist evenly throughout your paludarium, preventing stagnant air and moisture-related issues.

Key Features:

• Drip-Resistant Design: Can tolerate high humidity and occasional water contact without failure
• Reversible Mounting: Install externally (intake mode) to bring fresh air in, or internally (exhaust mode) to expel humid air
• Three-Speed Control: Adjust airflow intensity to match plant requirements and seasonal conditions
• 40mm Diameter: Perfect fit for System Paluda 300/600 side ventilation holes

How It Works:

Mount the fan with the airflow direction suited to your humidity goals:

• External (Intake): Fan outside the tank pulls fresh air in, lowering humidity and increasing evaporation—ideal for plants that prefer drier conditions or to prevent condensation buildup
• Internal (Exhaust): Fan inside the tank expels humid air, creating negative pressure that draws in drier ambient air—useful for rapid humidity cycling or preventing mold growth

Combine with Mistflow mist generator for complete climate control: the Mistflow raises humidity via ultrasonic fog, and the Circulation Fan 40 fine-tunes airflow to prevent waterlogged conditions or dead zones.

Applications:

• Humidity regulation in System Paluda 300/600
• Mist distribution to reach upper canopy plants
• Preventing condensation on glass tops and walls
• Simulating natural breeze for stronger stem development in terrestrial plants
• Reducing fungal and bacterial risks in densely planted setups

Installation Tips:

• Start on low speed and observe plant response over 24–48 hours
• For most tropical plants, mount externally on low speed to gently refresh air without drying out foliage
• Use higher speeds or internal mounting during dormant periods or when dealing with excessive moisture
