The Complete All-In-One Grow Room Ventilation Upgrade
Establish the perfect microclimate and eliminate unwanted smells with the AC Infinity 4” Inline Fan, Carbon Filter & Ducting Combo Kit. Designed as a complete, out-of-the-box ventilation package, this heavy-duty system includes everything you need to manage heat, humidity, and airflow in small grow tents or indoor gardens. Take the guesswork out of matching separate components—this hardware combination ensures optimal static pressure compatibility for efficient, leak-free performance.

At the core of this kit is a premium, mixed-flow 4-inch inline fan powered by an energy-efficient EC motor, delivering a capable 205 CFM airflow at a whisper-quiet noise level of just 28 dBA. It connects directly to the included Australian Virgin Charcoal Carbon Filter, which features a dense bed of high-porosity charcoal to scrub all organic odours, airborne pollutants, and pollen. Completed with a 4-layer flexible aluminum ducting line, this combo kit keeps your grow space running cool, clean, and completely discreet.

How to Install the AC Infinity 4" Ventilation Combo Kit

Follow these straightforward steps to safely mount, connect, and configure your complete extraction system.

1. Plan and Hang Your Components

Identify the airflow direction on the inline fan using the embossed arrow on the plastic body.
For optimal odor control, hang the Carbon Filter inside the top section of your grow tent using heavy-duty fabric straps.
Mount the Inline Fan next to the filter, making sure the arrow points away from the filter to pull stale air through the charcoal bed.

2. Connect the System with Ducting

Slide the raw end of the 4-inch aluminum ducting over the filter flange and connect it directly to the intake side of the fan.
Secure this connection tightly using one of the included stainless steel worm clamps to prevent unscrubbed air from bypassing the filter.
Attach the remaining ducting line to the exhaust side of the fan and route it out through your grow tent's ventilation socks to vent heat away from the room.

3. Power On and Set Fan Speeds

Fit the white fabric pre-filter sleeve over the outside of the carbon filter to catch large dust particles.
Plug the inline fan's power supply into a standard wall outlet.
Connect the included wired 10-speed controller to easily adjust your airflow across ten precise speeds, balancing effective cooling with minimum room noise.

Care and Maintenance Tips

Rotate the Pre-Filter: Wash the fabric pre-filter cloth every 3 to 4 months to prevent dust from choking the air intake and straining the fan motor.
Carbon Filter Lifespan: For best performance, replace the carbon filter every 12 to 24 months, depending on your grow room's relative humidity and odor intensity.
Tool-Free Cleanup: Unclip the fan's central motor box from the mounting frame to wipe down the impeller blades between harvest cycles without taking down your entire ducting array.
