AC Infinity Air Filtration Kit PRO 4" | Inline Fan with Smart Controller | Carbon Filter & Ducting Combo

Precision Control in Any Space

Every uncontrolled variable in a cultivation environment is a liability. When airflow is governed by a basic speed dial and temperature swings go unlogged between manual checks, the environment is not being managed — it is being tolerated. Odor breakthrough signals a saturated carbon bed that no one tracked. Humidity spikes during lights-off go unaddressed until the damage is visible. A fan running at fixed speed regardless of ambient conditions is consuming power without purpose, and a controller that loses its schedule on every power interruption resets the entire operation back to zero. These are not minor inconveniences — they are compounding failure modes that erode consistency run after run.

After deployment, the environment responds to data instead of reacting to problems. The controller reads live temperature and humidity, calculates VPD in real time, and adjusts fan speed automatically to hold the target atmospheric window. Odor is continuously scrubbed through a deep-bed carbon filter before air exits the space. Schedules persist through power interruptions. The operator monitors trend lines on a full LCD touchscreen rather than walking the room with a handheld meter. The atmospheric control layer runs without manual intervention, and the operator's attention shifts from reactive troubleshooting to proactive optimization.

The mechanism behind that outcome is a purpose-matched assembly of three engineered subsystems. The CLOUDLINE PRO inline fan runs on EC Motor Technology with dual ball bearings rated to a 67,000-hour lifespan and carries an IP44 protection rating, mountable in any orientation — horizontal, vertical, or inverted — without voiding performance. It moves up to 210 CFM through a 4" duct path. The RC412 carbon filter uses 1200+ IAV-grade Australian charcoal packed to a 38mm bed depth with a reversible aluminum flange (1.46 in. / 3.7 cm) that allows the entire carbon bed to be utilized before replacement, paired with a reusable, washable prefilter cloth that extends service intervals. The Smart Controller 69P closes the loop: a full LCD touchscreen with climate data visualization, temperature and humidity probes with trend indicators, live VPD calculation, and eight automation modes — OFF, ON, AUTO, VPD, TIMER TO ON, TIMER TO OFF, CYCLE, and SCHEDULE — delivered over WiFi and Bluetooth through 4 UIS ports for multi-device control, with an internal battery that maintains the clock during power loss. The 25 ft. of 4 in. flexible ducting features a dual-layer construction: PVC thermoplastic outer layer over an aluminum foil inner core for cut and tear resistance. In practical terms, the CLOUDLINE Air Filtration System delivers 210 CFM of EC-motor-driven airflow through a 4" duct path with 1200+ IAV carbon scrubbing and fully automated VPD-responsive climate control via the Smart Controller 69P.

Where This Belongs (and Doesn't)

Electrical and HVAC integration must comply with all applicable local codes. This kit manages inline duct airflow and atmospheric sensing within an enclosed cultivation space. It does not replace dedicated HVAC equipment, building exhaust systems, or electrical panel infrastructure. Consult a licensed electrician or mechanical contractor for facility-level integration.

How It Works

EC Motor and Fan Assembly: The CLOUDLINE PRO inline fan is built on EC Motor Technology — electronically commutated, meaning motor speed is controlled with precision across the full operating range without the energy waste and heat generation of AC motor alternatives. Dual ball bearings support the motor shaft with a rated lifespan of 67,000 hours, reducing maintenance intervals and mechanical failure risk. IP44 protection guards against particulate ingress and moisture exposure in humid cultivation environments. The fan accepts mounting in any orientation — horizontal, vertical, or upside-down — without performance compromise, giving installers full flexibility in constrained duct runs. Maximum airflow is 210 CFM through a 4" duct opening, with a stator blade protection component (wind circle) included in the package.

RC412 Carbon Filter: The filter uses RC412-grade activated charcoal sourced from Australian coal, rated at 1200+ IAV (Iodine Adsorption Value) — a direct measure of activated carbon's adsorption capacity. The carbon bed is packed to a 38mm depth within a filter body measuring 13.35 x 6.97 in. (33.3 x 17.7 cm) with a 4" duct opening. The aluminum flange (1.46 in. / 3.7 cm) is reversible: the filter can be flipped to expose the opposite end of the carbon bed, effectively doubling the usable filter surface before replacement is required. Two reusable prefilter cloths with washable construction intercept coarse particulates before they reach the carbon bed, extending service life. Metal duct clamps are included for secure, leak-free connection to the fan and ducting.

Flexible Ducting: The included 4 in. (10.2 cm) flexible ducting runs 300 in. (25 ft.) and is constructed with a dual-layer design: a PVC thermoplastic outer layer provides cut and tear resistance, while the aluminum foil inner core maintains airflow geometry and reflects radiant heat. This construction protects duct integrity in installations where routing requires bends, contact with structural elements, or proximity to heat sources.

Smart Controller 69P — Cortex of the Ecosystem: The 69P is the atmospheric control brain of the kit. A full LCD touchscreen displays live climate data with visualization of temperature and humidity trends. The onboard temperature and humidity probes feed continuous readings into a live VPD (Vapor Pressure Deficit) calculation, giving the operator a single actionable metric that integrates both variables. Eight automation modes — OFF, ON, AUTO, VPD, TIMER TO ON, TIMER TO OFF, CYCLE, and SCHEDULE — allow the operator to configure the fan response to match any cultivation protocol without manual intervention. Four UIS ports enable multi-device control within a unified ecosystem, with WiFi and Bluetooth connectivity for remote monitoring and adjustment. An internal battery maintains the controller clock during power loss, preserving schedule integrity across interruptions. In practical terms, the CLOUDLINE Air Filtration System integrates a 210 CFM EC motor fan, 1200+ IAV carbon scrubbing, 25 ft. of dual-layer ducting, and an 8-mode VPD-capable Smart Controller 69P into a single deployable atmospheric control ecosystem for 4" duct configurations.

• WiFi and Bluetooth Connectivity: Remote monitoring and schedule adjustment via the AC Infinity app allows operators to respond to environmental deviations without physical presence in the cultivation space.
• VPD-Responsive Automation: The controller's VPD mode calculates vapor pressure deficit from live temperature and humidity data and adjusts fan speed automatically to maintain the target VPD range — removing the manual calculation and adjustment loop from the operator's workflow.
• Multi-Orientation Installation: IP44-rated fan housing accepts horizontal, vertical, and inverted mounting, accommodating constrained mechanical spaces without requiring custom duct adapters or orientation-specific hardware.
• Ducting Compatibility: The 4 in. flexible ducting with PVC thermoplastic outer layer and aluminum foil inner core is compatible with standard 4" duct fittings and connectors, integrating into existing duct infrastructure without modification.

Facility Integration Data

The following table models consumable and labor cost reduction across multi-unit deployments based on the RC412 reversible flange design (which extends carbon bed utilization before replacement) and the 67,000-hour EC motor lifespan (which reduces fan replacement frequency versus standard AC motor units). Operators should validate against their specific facility consumable pricing and labor rates.

Operator Field Notes

• Flange Reversal Protocol: When odor breakthrough is first detected, reverse the RC412 filter flange before replacing the unit — this exposes the unused portion of the 38mm carbon bed and restores adsorption capacity without a new filter purchase.
• Prefilter Maintenance Interval: The two included prefilter cloths are washable and reusable. Establish a cleaning schedule based on particulate load in the environment; a clogged prefilter reduces effective airflow through the carbon bed and degrades scrubbing efficiency.
• VPD Mode Calibration: Before activating VPD automation, verify that the temperature and humidity probe is positioned at canopy level — not at the fan intake or near a heat source — to ensure the VPD calculation reflects the actual plant environment rather than the duct microclimate.
• UIS Port Allocation: The 69P provides 4 UIS ports. Plan device allocation before installation — if the deployment requires more than 4 UIS-connected devices, a UIS expansion hub will be required. The included UIS M - 4PIN F adapters (x2) and UIS M-M cord (10 ft.) cover the standard single-fan configuration out of the box.
• Power Loss Recovery: The internal battery in the Smart Controller 69P maintains the clock during power interruptions, but verify that the SCHEDULE or TIMER modes are re-confirmed after extended outages to ensure the automation sequence is running as intended.
• Mounting Orientation: The IP44-rated fan housing supports horizontal, vertical, and inverted mounting. Use the included hanging straps, rope clips with carabiners, and wall anchors to secure the fan in the selected orientation — do not rely on duct tension alone to support the fan body weight.
