Stop Buying. Start Manufacturing Top-Shelf Inventory.

Consumer-grade equipment and guesswork-driven growing impose a cost that never shows up on a single invoice — it accumulates across every batch. Fixed-speed fans that cannot modulate to room demand create pressure swings that destabilize VPD. Uncontrolled exhaust runs spike temperature differentials between canopy zones. Every degree of variance, every humidity excursion, every CO2 bleed event that goes unmanaged is a direct deduction from final yield weight and terpene density. The operator absorbs that loss silently, batch after batch, without a line item to point to.

After deploying a properly sized, variable-speed atmospheric control platform, the facility operates on a different logic. Airflow is dialed to the exact CFM the room demands at each growth stage. Pressure differentials across the canopy stabilize. Temperature and humidity setpoints hold without manual correction between shifts. The environment becomes a repeatable input — and repeatable inputs produce repeatable output. That is the operational definition of manufacturing.

The CLOUDLINE S6 achieves this through an EC motor with PWM (Pulse Width Modulation) control — the same motor architecture used in precision HVAC and data center cooling applications. EC motors modulate speed electronically across ten discrete speed levels, drawing only the wattage the current demand requires, with a ceiling of 70W at full draw. At peak, the unit moves 402 CFM against up to 503 Pa of static pressure through a 6-inch duct run, while holding acoustic output to 32 dBA — a noise floor that does not interfere with sensor arrays or staff communication in the room. The integrated speed controller retains its last programmed setting through power interruptions via backup memory, eliminating manual reset overhead after outages. In practical terms, the CLOUDLINE S6 delivers 402 CFM of variable, EC-controlled airflow through a 6-inch duct at a maximum draw of 70W, with a rated L10 service life of 67,000 hours.

Where This Belongs (and Doesn't)

This unit requires a dedicated circuit capable of supplying 100–240V AC at 50/60Hz. Duct integration and mounting must be performed by qualified personnel. Verify that your exhaust or intake run is sized for 6-inch duct diameter before ordering.

Infrastructure Note: The CLOUDLINE S6 ships with a 10-foot cord to the included speed controller. Verify that your electrical supply point and duct termination are within reach before finalizing mounting position. Fan unit dimensions are 7.87 x 12.60 x 8.35 in. (21.2 x 32.0 x 20.0 cm); confirm clearance in your duct chase or ceiling plenum before installation.

How It Works

The CLOUDLINE S6 is built around an EC (Electronically Commutated) motor with PWM control — a motor architecture that eliminates the fixed-speed limitation of conventional AC induction motors. Where a standard AC motor runs at a single RPM determined by line frequency, the EC motor in the S6 accepts a PWM signal from the speed controller and modulates rotor speed continuously across ten discrete speed levels. This means the fan draws only the wattage the current room demand requires — not the full 70W ceiling unless the room actually needs it. The result is lower heat output into the duct run, reduced electrical draw during partial-load operation, and a noise floor that holds to 32 dBA even at mid-range speeds, because the motor is not fighting against a fixed-speed governor.

At full speed, the S6 moves 402 CFM against a maximum static pressure of 503 Pa — sufficient to overcome resistance in moderately long duct runs with standard fittings. The 6-inch duct collar interfaces with standard flexible and rigid duct systems. Mounting hole-to-hole distance is 3.15 x 2.36 in. (8.0 x 6.0 cm) with a screw hole diameter of 0.236 in. (0.6 cm), allowing direct bracket or flange mounting in standard ceiling or wall installations. The included speed controller — dimensions 3.34 x 2.95 x 0.51 in. (8.5 x 3.6 x 1.3 cm) — connects via a 120-inch (10-foot) cord, giving operators flexibility in controller placement relative to the fan body. The backup memory feature retains the last programmed speed level through power interruptions, so the unit returns to its pre-set operating point automatically after an outage without requiring operator intervention. The unit is ETL, CE, RoHS, SAA, and IC certified, confirming compliance with U.S. electrical safety standards and international quality benchmarks. In practical terms, the CLOUDLINE S6 delivers variable EC-controlled airflow up to 402 CFM at 32 dBA through a 6-inch duct at a maximum draw of 70W, with a rated L10 service life of 67,000 hours.

System Integration

To operate this platform at peak efficiency, verify your ecosystem matches these requirements:

• Power Supply: Requires 100–240V AC at 50/60Hz. Confirm your circuit can supply the 70W maximum draw; a dedicated 15A circuit is recommended for multi-fan installations on the same run.
• Duct Compatibility: 6-inch duct diameter required. Confirm all fittings, reducers, and carbon filter collars in the run are sized to 6 inches before installation.
• Controller Placement: The included speed controller connects via a 120-inch (10-foot) cord. Plan mounting position so the controller is accessible to operators without requiring ladder access during routine speed adjustments.
• UIS Ecosystem Compatibility: The CLOUDLINE S6 is compatible with AC Infinity's UIS (Universal Intelligence System) controller ecosystem. If integrating with an AC Infinity Cortex controller for automated scheduling or sensor-triggered speed control, verify controller firmware version supports the S Series fan protocol.
• HVAC Sizing: The S6 moves up to 402 CFM of conditioned or exhaust air. Verify that your HVAC system can compensate for the volume of air being exhausted to maintain target room temperature and humidity setpoints.

Facility Integration Data

Use the data below to model fleet-level deployment costs and annual operational overhead for the CLOUDLINE S6 across your facility build-out.

Operator Field Note

• Fan Unit Dimensions: 7.87 x 12.60 x 8.35 in. (21.2 x 32.0 x 20.0 cm). Confirm clearance in your duct chase, ceiling plenum, or inline mounting position before installation. Mounting hole-to-hole distance is 3.15 x 2.36 in. (8.0 x 6.0 cm); screw hole diameter is 0.236 in. (0.6 cm).
• Weight: Not specified in source data. Verify structural support capacity of your mounting bracket or duct hanger before suspending the unit. Do not rely on duct collar alone as the primary load-bearing connection.
• Electrical Draw: Maximum draw is 70W at 100–240V AC, 50/60Hz. On a standard 15A/120V circuit, this unit draws less than 0.6A at full load — allowing multiple units per circuit, subject to total circuit load calculations by a licensed electrician.
• Controller Cord Length: The speed controller connects via a 120-inch (10-foot) cord. Plan your mounting layout so the controller is positioned at an accessible height for routine speed adjustments without requiring tools or ladder access.
• Static Pressure Rating: Maximum static pressure is 503 Pa. For duct runs with multiple bends, long horizontal runs, or high-resistance carbon filter media, calculate total system resistance before assuming the S6 will deliver full 402 CFM at the terminal point.
• Certifications: ETL, CE, RoHS, SAA, and IC certified. Confirm that your jurisdiction's AHJ (Authority Having Jurisdiction) accepts ETL listing as equivalent to UL listing for permit purposes before installation.
