Kill Variance. Print Yield.

Every uncontrolled air exchange is a data point your facility never recorded — a temperature spike that compressed internodes, a humidity plateau that opened the door to pathogen pressure, a CO2 pocket that stalled photosynthetic rate during peak light hours. Legacy fixed-speed fans and passive exhaust configurations do not respond to those events. They run at a single output regardless of room demand, leaving the gap between setpoint and actual condition to accumulate silently across every hour of every cycle. That gap is not an inconvenience — it is a direct tax on yield consistency, and it compounds with every room, every run, and every operator shift change.

After deploying the CLOUDLINE S12 into a sealed cultivation ecosystem, the facility operates on a different logic. The controller reads environmental conditions and adjusts airflow output in real time, holding rooms closer to setpoint without manual intervention. Duct runs that previously required oversized fans to overcome static pressure resistance now operate at the precise speed the room demands — quieter, more efficient, and without the thermal load of a motor running at full draw when the room needs 40% output. Operators stop chasing variance and start reading consistent harvest data.

The mechanism behind that outcome is a PWM-controlled EC (electronically commutated) motor driving a mixed-flow impeller through a 12-inch duct at up to 1,604 CFM against 818 Pa of static pressure — performance that holds in high-resistance duct configurations where standard AC motors stall or cavitate. Maximum power draw is 250W; average operating draw under programmed conditions is 139W at 2.5A, reflecting the efficiency advantage of PWM modulation over fixed-speed AC motor designs. The smart controller supports ten discrete speed levels, dynamic climate-based programming, time-based scheduling, and multi-device UIS connectivity, with backup memory that retains the last speed setting through any power interruption. In practical terms, the CLOUDLINE S12 delivers 1,604 CFM at 818 Pa static pressure through a 12-inch duct at a maximum draw of 250W / 2.5A with an L10 life expectancy of 67,000 hours.

Where This Belongs (and Doesn't)

This unit requires a dedicated 15A minimum circuit (120V or 240V, 50/60Hz). Duct infrastructure must be sized for 12-inch connections. Verify HVAC load calculations before deployment — the fan unit itself generates a thermal load that must be accounted for in room heat balance.

Infrastructure Note: Fan unit dimensions are 12.28 x 17.71 x 14.05 in. (31.2 x 45.0 x 35.7 cm). Controller cord to fan is 120 in. (10 feet); cord to plug is 96 in. (8 feet). Confirm mounting clearance and cord routing before installation.

How It Works

The CLOUDLINE S12 uses an inline mixed-flow design — a hybrid geometry that combines the high-static-pressure capability of a centrifugal fan with the high-volume airflow of an axial fan. This allows the unit to maintain 1,604 CFM even in duct configurations with significant resistance, where a standard axial inline fan would experience substantial CFM loss. The impeller and motor are housed in a detachable motor box that separates from the mounted frame without disconnecting the duct run, enabling maintenance and cleaning without full system teardown.

The EC motor at the core of the unit is controlled via PWM (Pulse Width Modulation), which modulates motor speed by varying the duty cycle of the electrical signal rather than reducing voltage. This produces precise, stable speed control across ten discrete levels without the torque instability and heat generation associated with voltage-reduction speed control on AC motors. The result is a motor that runs at extremely low RPM speeds without generating the harmonic noise characteristic of AC motor designs operating below rated speed. The smart controller supports dynamic climate-based programming — adjusting fan speed in response to temperature and humidity sensor inputs — as well as time-based scheduling for lights-on/lights-off ventilation profiles. The controller connects to multiple UIS-platform devices, enabling coordinated atmospheric control across fans, controllers, and environmental sensors within a single ecosystem. Backup memory retains the last programmed speed setting through any power interruption, eliminating manual reset requirements after facility power events. In practical terms, the CLOUDLINE S12 operates at 139W average draw (250W max) at 2.5A, delivering 1,604 CFM at 818 Pa static pressure with an L10 life expectancy of 67,000 hours across a 100-240V AC, 50/60Hz supply.

System Integration

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

• Controller Compatibility: Included smart controller supports UIS platform connectivity. For multi-zone deployments, verify that additional UIS sensors and controllers are provisioned before installation.
• Duct Infrastructure: Requires 12-inch duct connections. Mounting hole-to-hole distance is 7.00 x 7.12 in. (17.8 x 18.1 cm); screw hole diameter is 0.462 in. (1.18 cm). Confirm structural mounting capacity for a unit measuring 12.28 x 17.71 x 14.05 in. (31.2 x 45.0 x 35.7 cm).
• Electrical Supply: 100-240V AC, 50/60Hz. Maximum draw 250W / 2.5A. Dedicate a minimum 15A circuit. Verify supply voltage matches unit rating before energizing.
• HVAC Load: Average operating draw of 139W contributes to room thermal load. Include fan heat output in HVAC sizing calculations for sealed room environments.
• Cord Routing: Controller cord is 120 in. (10 feet) from fan unit; power cord is 96 in. (8 feet) to plug. Plan mounting position to accommodate cord runs without extension cords on the power circuit.

Facility Integration Data

Use the following data to model fleet-level deployment costs and operational impact across your facility build-out.

Operator Field Note

• Weight and Mounting: Fan unit dimensions are 12.28 x 17.71 x 14.05 in. (31.2 x 45.0 x 35.7 cm). Mounting hole-to-hole distance is 7.00 x 7.12 in. (17.8 x 18.1 cm) with a screw hole diameter of 0.462 in. (1.18 cm). Verify that the mounting structure — duct hangers, ceiling anchors, or inline brackets — is rated for the unit's weight and vibration load before installation.
• Electrical Draw: Maximum draw is 250W at 2.5A. Average programmed draw is 139W. Install on a dedicated circuit with a minimum 15A breaker. Do not share the circuit with high-inrush equipment. Supply must be 100-240V AC, 50/60Hz.
• Cord Management: The controller cord from the fan unit is 120 in. (10 feet). The power cord to the plug is 96 in. (8 feet). Plan mounting position to reach both the duct connection and the power outlet without extension cords on the power side of the circuit.
• Maintenance Access: The motor box containing the impeller and blades detaches from the mounted frame for cleaning without removing the unit from the duct run. Schedule periodic impeller cleaning per facility maintenance intervals — debris accumulation on the impeller reduces CFM output and increases motor load.
• Power Interruption Behavior: The controller retains the last programmed speed setting through power loss via backup memory. Verify that the retained setting is appropriate for post-restoration room conditions before assuming automated recovery is sufficient after a facility power event.
• Noise Threshold: Maximum noise output is 62 dBA at full speed. If facility acoustic requirements are below this threshold, program the controller to a reduced speed level and verify dBA output at that setting against room requirements.
