Air Mixed Flow Fan. High Efficiency Inline Ventilation Fan for Hydroponic Grow Rooms (100mm–250mm)

The Air Mixed Flow Fan is a high-efficiency inline ventilation solution engineered for controlled environment applications. Designed to deliver high air volume at elevated static pressure, this fan is well suited to hydroponic grow rooms, grow tents, and HVAC airflow systems requiring reliable, continuous ventilation performance.

Utilising mixed-flow impeller technology, the unit combines axial and centrifugal airflow characteristics to maintain consistent air delivery under resistance from carbon filters and ducting systems. The sealed housing design improves durability while reducing acoustic leakage, making it suitable for continuous operation in enclosed grow environments.

Available in diameters from 100mm to 250mm, this fan provides scalable airflow solutions for small to medium grow setups, with speed control compatibility for precise airflow management across varying environmental conditions.

Key Benefits

Mixed-flow impeller technology for high pressure and high volume output. Combines axial and centrifugal airflow characteristics to maintain consistent air delivery under resistance from carbon filters, ducting bends, and system restrictions.

Integrated mounting brackets. Factory-fitted brackets enable secure, flexible installation in grow tents, grow rooms, and ducting runs without additional hardware.
Low power consumption relative to airflow output. Energy-efficient operation reduces running costs for continuous grow room ventilation without compromising airflow performance.
12-month warranty. Manufacturer-backed reliability for continuous operation in hydroponic and HVAC ventilation applications.

High Efficiency Mixed Flow Air Technology

Mixed-flow fans are engineered to maintain airflow efficiency under pressure load, making them the preferred choice for hydroponic ventilation systems where carbon filters and ducting create significant static resistance. The Air Mixed Flow Fan delivers the following performance characteristics.

High static pressure output. Maintains airflow through carbon filters and extended ducting runs where axial fans lose efficiency under load.
Large air volume movement. Efficient air exchange in enclosed environments for rapid temperature and humidity correction.
Energy efficiency. Low power consumption relative to output reduces operating costs for continuous grow room ventilation.
Acoustic control. Sealed housing reduces operational noise via acoustic containment of impeller and motor noise.
System stability. Consistent airflow delivery supports stable environmental conditions across the full growth cycle.

Inline Fan for Hydroponic Ventilation Systems

Ventilation is a critical parameter in controlled environment agriculture. The Air Mixed Flow Fan contributes to the following essential environmental functions in hydroponic systems.

Temperature regulation. Removes excess heat generated by grow lighting systems, maintaining optimal canopy temperature for plant metabolism and growth.
Humidity control. Extracts moisture-laden air from enclosed grow environments, reducing condensation risk and limiting conditions that favour mould and fungal development.
CO2 exchange. Maintains fresh air supply to the grow space, supporting plant photosynthesis and preventing CO2 depletion in sealed environments.
Odour control integration. Compatible with carbon filter systems for complete odour management in enclosed cultivation environments.
Airflow uniformity. Consistent inline airflow supports stable temperature and humidity distribution across the grow room canopy.

Frequently Asked Questions

What size fan do I need for my grow tent?

A general rule is to replace the air volume in your tent every 1–3 minutes. Calculate your tent volume (length × width × height in metres) and select a fan rated to move that volume per minute. For Air Mixed Flow Fan, check the airflow specification (m³/hr) and divide by 60 to get m³/min. Allow extra capacity if you are running a carbon filter, as filters reduce effective airflow by 20–25%.

How loud is Air Mixed Flow Fan?

Air Mixed Flow Fan is engineered for low-noise operation. The dB rating is listed in the product specifications — for reference, under 35dB is near-silent in a closed room, 40–50dB is comparable to a quiet office, and over 55dB will be audible through walls. For stealth grows or home setups, pair Air Mixed Flow Fan with an acoustic duct silencer to further reduce sound transmission.

Can I control the speed of Air Mixed Flow Fan?

Yes — Air Mixed Flow Fan is compatible with fan speed controllers. EC-motor fans are best paired with dedicated EC controllers for smooth, stepless speed control. AC-motor fans work with standard voltage-based speed controllers. Running your fan at 70–80% speed is a practical balance between airflow performance, noise reduction, and motor longevity.

How do I install Air Mixed Flow Fan in my grow tent?

Mount Air Mixed Flow Fan at the top of your grow tent using the included hanging brackets or a custom ratchet hanger. Connect ducting between Air Mixed Flow Fan and your carbon filter using appropriate duct clamps. Ensure all connections are sealed to maximise negative pressure and eliminate light leaks. Intake air should enter near the bottom of the tent and exhaust should exit from the top.

Does Air Mixed Flow Fan ship fast within Australia?

Yes — Air Mixed Flow Fan ships from our Australian warehouse with fast tracked delivery Australia-wide. Most east coast orders arrive within 2–5 business days. WA, NT, and TAS orders typically arrive within 5–12 business days.
