AC Infinity Air Filtration Kit PRO 4-Inch with CONTROLLER AI+ | AC-FKT4

Create a cleaner, more stable indoor growing environment with the AC Infinity Air Filtration Kit PRO 4-Inch. This complete ventilation package combines a quiet, energy-efficient inline fan with the intelligent CONTROLLER AI+, a premium activated carbon filter, and flexible ducting for an integrated solution to heat, humidity, airflow, and odor management.

Designed for grow tents, indoor gardens, hydroponic systems, and controlled growing spaces, the kit removes stale air, helps manage excess heat and humidity, and filters unwanted odors before exhaust air leaves the growing area.

Intelligent AI-Powered Climate Control

The included AC Infinity CONTROLLER AI+ continuously observes environmental conditions and dynamically adjusts the inline fan to help maintain a more stable grow space.

Unlike basic on/off controllers, the AI-powered system analyzes previous environmental responses and anticipates temperature and humidity changes. This allows it to adjust fan output more precisely while reducing unnecessary speed fluctuations and environmental overshooting.

Connect the controller to the AC Infinity app through Wi-Fi for remote access to environmental data, intelligent climate insights, customizable programming, grow guides, and additional system controls.

Upgraded 205 CFM Inline Fan

The included 4-inch CLOUDLINE inline fan delivers up to 205 CFM of airflow while operating at a quiet 29 dBA. Its PWM-controlled EC motor provides energy-efficient performance, smooth speed control, and dependable operation at low fan speeds.

A mixed-flow design, stator blades, and hydrodynamic wind circles help move air efficiently through ducting and filtration equipment. The dual-ball-bearing motor offers an estimated 67,000-hour operating life, while the IP44-rated housing helps protect the fan against dust and splashing water.

Premium Australian Carbon Filtration

The included 4-inch carbon filter uses Australian virgin RC412 activated charcoal with a 1200+ IAV rating to capture unwanted odors and airborne chemicals.

Its 38 mm carbon bed provides a large adsorption surface, while the galvanized steel mesh body and corrosion-resistant gunmetal finish support dependable use in humid indoor growing environments. A washable prefilter cloth helps capture larger particles before they reach the activated carbon.

Flexible Four-Layer Ducting

The included 4-inch flexible ducting provides up to 25 feet of routing length, giving growers flexibility when positioning intake or exhaust components.

Its four-layer construction combines aluminum foil, a spiral steel-wire frame, and a protective thermoplastic outer layer to resist tearing, leaks, and excessive wear. Included clamps and hanging hardware help simplify installation inside or outside a grow tent.

Part of the UIS Ecosystem

This ventilation kit is part of AC Infinity’s UIS ecosystem, allowing compatible grow devices to work together through a centralized smart controller. Additional UIS devices can be integrated as the growing environment expands, creating a more unified approach to climate and equipment management.
