AC Infinity Air Filter Box with High Efficacy Filter

The AC Infinity Air Filter Box with High Efficacy Filter is a professional inline air filtration system designed to improve air quality in grow rooms, grow tents, hydroponic environments and ventilation installations. Installed directly into a compatible ducting system, the filter box helps capture airborne dust, pollen and other fine particles before they circulate through your growing environment.

Designed for use with inline duct fans, the filtration box combines a durable steel enclosure with a replaceable high-efficiency pleated filter. Its enclosed design allows air to pass through the filtration media while helping reduce the amount of airborne contamination entering or circulating within an indoor growing space.

Featuring a hinged access door, secure slide-lock mechanism and neoprene sealing, the AC Infinity inline air filter box provides convenient access for filter replacement while helping maintain an effective seal during operation.

Available in 4-inch, 6-inch, 8-inch and 10-inch sizes, the AC Infinity Air Filter Box is a practical addition to ventilation systems where cleaner intake air, equipment protection and straightforward filter maintenance are priorities.

Specifications

Who It’s For

The AC Infinity Air Filter Box with High Efficacy Filter is ideal for indoor gardeners, hydroponic growers, greenhouse operators and ventilation installers who want to reduce airborne particles entering an enclosed environment.

It is particularly useful for grow tent intake filtration, dedicated grow room ventilation, workshops and other spaces where airborne dust and pollen may be a concern. By helping filter incoming air, the unit can contribute to a cleaner growing environment and reduce the amount of particulate matter entering the ventilation system.

With 4-inch, 6-inch, 8-inch and 10-inch options, the range can be matched to different duct sizes and compatible inline extraction or intake fans. The durable steel enclosure, replaceable filtration media and convenient access door make it suitable for installations requiring regular maintenance and long-term use.

For growers operating indoor hydroponic systems, maintaining cleaner incoming air can help reduce dust accumulation on growing equipment and surfaces. The AC Infinity Air Filter Box provides a dedicated filtration stage that can be incorporated into an existing ventilation setup.

How To Use

Select the AC Infinity Air Filter Box size that matches your ventilation ducting and inline fan. For intake filtration, position the unit near the beginning of the air intake system so incoming air passes through the filter before reaching the ventilated space.

Securely connect the matching duct flanges to the ventilation ducting and ensure the installation is properly supported. A suitable high static pressure inline fan, such as a compatible AC Infinity CLOUDLINE model, is recommended to help maintain airflow through the filtration media.

Before operation, open the hinged access door and check that the supplied pleated filter is correctly seated in its internal slot. Close the door and secure the slide lock, ensuring the neoprene seal is properly positioned.

Switch on the ventilation system and check for adequate airflow and secure duct connections. Inspect the filter regularly, particularly in dusty environments or during continuous operation.

When the filtration media requires replacement, switch off the connected fan, release the slide lock and remove the used filter. Fit a compatible replacement of the correct dimensions, then close and secure the access door before restarting the system.

For reliable grow room air filtration, always follow the manufacturer's installation guidance and select a fan capable of overcoming the additional resistance created by the filter.
