Stop Buying. Start Manufacturing Top-Shelf Inventory.

Consumer-grade equipment and guesswork-driven growing impose a cost that never appears on a single invoice — it accumulates in batch variance, in canopy microclimates that drift between day and night cycles, in motors that hum loud enough to mask the sound of a room going out of spec. Fixed-speed fans run at full draw regardless of demand, burning watts and generating heat that your HVAC system has to compensate for. Brushed motors degrade on a curve you cannot predict, and when they fail mid-cycle, the loss is not just the motor — it is the run. Every hour of uncontrolled atmospheric drift is an hour your facility is not manufacturing; it is gambling.

After deploying the CLOUDLINE A4, the room operates on a schedule, not on approximation. Airflow ramps up when CO2 injection peaks and steps down during dark periods without a technician touching a dial. The controller retains its last programmed speed through a power interruption, so a tripped breaker does not reset your environmental protocol to factory defaults at 2 a.m. Odor management runs continuously at the minimum effective speed, keeping noise below the threshold that triggers staff complaints or neighbor attention. The facility breathes on a defined, repeatable program — and repeatable programs produce repeatable harvests.

The mechanism behind that consistency is an EC motor controlled via PWM (Pulse Width Modulation), which allows the CLOUDLINE A4 to run smoothly at extremely low RPM without generating the motor noise characteristic of fixed-speed AC units. At maximum draw, the unit pulls only 35 watts while moving 165 CFM against a static pressure rating of 324 Pa — enough to push through restrictive carbon filter and ducting configurations without stalling. Dual ball bearings rated at 67,000 hours allow mounting in any orientation, horizontal or vertical, without bearing wear penalty. The IP44 rating provides resistance to dust and moisture ingress in environments where humidity management is active. The included wired 10-speed controller ships with backup memory and is forward-compatible with all CLOUDLINE Series smart controllers within the UIS ecosystem. In practical terms, the CLOUDLINE A4 delivers 165 CFM through 4-inch duct at 35 watts maximum draw, with a noise floor of 29 dBA and a rated service life of 67,000 hours.

Where This Belongs (and Doesn't)

Minimum infrastructure requirement: a dedicated 4-inch duct run with appropriate fittings and a standard 100–240V AC outlet. HVAC load calculations should account for the fan's heat contribution and the thermal load of the space being ventilated before sizing this unit into a sealed room design.

Infrastructure Note: The CLOUDLINE A4 ships with 72-inch (6-foot) cord lengths to both the controller and the power plug. Verify that your mounting location accommodates these fixed cord runs before installation. The motor box detaches from the mounting frame for cleaning without full disassembly.

How It Works

The CLOUDLINE A4 uses a mixed-flow impeller geometry — a design that combines the high-static-pressure characteristics of an axial fan with the high-volume airflow characteristics of a centrifugal fan. This geometry allows the unit to maintain 165 CFM delivery even when back-pressure from carbon filters, duct bends, or long duct runs would stall a standard axial fan. The rated static pressure ceiling of 324 Pa means the fan continues to move air through restrictive configurations without the motor hunting or surging.

Power delivery to the impeller comes from an EC (electronically commutated) motor, which is governed by PWM (Pulse Width Modulation) signal from the included controller. PWM control allows the motor to operate at precise fractional speeds — down to very low RPM — without the cogging, audible hum, or heat generation that characterizes AC induction motors running below their rated frequency. At maximum speed (2800 RPM), the unit draws 35 watts. At lower speed settings, draw scales proportionally downward, reducing both electrical consumption and thermal output in the room. The 10-speed wired controller includes a backup memory function: the last programmed speed setting is retained through power interruptions, so the fan resumes its prior operating point automatically when power is restored.

The motor assembly is mounted on dual ball bearings rated at an L10 life of 67,000 hours. Dual ball bearing construction — as opposed to sleeve bearings — allows the unit to be mounted in any orientation, horizontal or vertical, without accelerated wear on the bearing race. The IP44 rating certifies resistance to solid particle ingress (4mm and larger) and water splash from any direction, making the unit appropriate for high-humidity cultivation environments. A vibration-dampening plastic mounting base is included to decouple motor vibration from the duct structure, keeping the noise floor at 29 dBA. The motor box containing the impeller and blades detaches from the mounted frame for periodic cleaning without requiring full duct disassembly. The CLOUDLINE A4 is part of the UIS platform and is forward-compatible with all CLOUDLINE Series smart controllers, enabling temperature, humidity, and schedule-based automation when paired with an appropriate AC Infinity controller. In practical terms, the CLOUDLINE A4 delivers 165 CFM through a 4-inch duct at a maximum of 35 watts, with a 324 Pa static pressure rating, 29 dBA noise floor, and a 67,000-hour L10 bearing life across horizontal or vertical mounting positions.

System Integration

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

• Controller Compatibility: Ships with a wired 10-speed fan controller (72-inch cord). Compatible with all CLOUDLINE Series smart controllers within the AC Infinity UIS ecosystem for temperature, humidity, timer, and schedule-based automation.
• Duct Infrastructure: Requires 4-inch duct fittings, clamps, and flexible or rigid duct rated for the CFM and static pressure of your run. Verify duct diameter matches at both the fan inlet and outlet before installation.
• Power Supply: Universal input voltage 100–240V AC, 50/60Hz. Standard outlet compatible. Maximum draw is 35 watts — confirm circuit capacity accounts for all devices on the shared circuit.
• HVAC Load: At 35W maximum draw, the unit contributes a modest thermal load to the room. Include this in HVAC sizing calculations for sealed environments with tight temperature tolerances.
• Mounting Hardware: Mounting hole-to-hole distance is 3.15 x 2.36 in. (8.0 x 6.0 cm) with 0.197 in. (0.5 cm) screw hole diameter. Verify mounting surface or bracket accommodates these dimensions before installation.

Operator Field Note

• Weight and Structural: Total fan dimensions are 7.48 x 11.89 x 6.93 in. (19.0 x 30.2 x 17.6 cm). Mounting hole-to-hole distance is 3.15 x 2.36 in. (8.0 x 6.0 cm) with 0.197 in. (0.5 cm) screw hole diameter. Verify that the mounting surface or hanging bracket is rated for the unit's weight and vibration load before installation.
• Electrical: Maximum power draw is 35 watts at 100–240V AC, 50/60Hz. The unit is cord-and-plug connected with 72-inch (6-foot) cords to both the controller and the power outlet. Confirm that cord lengths reach your outlet and controller mounting position without extension cords before finalizing installation location.
• Controller Dimensions: The included wired controller measures 3.34 x 2.95 x 0.51 in. (8.5 x 3.6 x 1.3 cm). Plan a mounting location within 72 inches of the fan unit for the controller.
• Environmental Setpoints: IP44 rating covers resistance to solid particles 4mm and larger and water splash from any direction. The unit is not rated for submersion or direct water jet exposure. Maintain ambient operating conditions within the manufacturer's specified range for the EC motor.
• Maintenance Access: The motor box containing the impeller and blades detaches from the mounted frame for cleaning. Schedule periodic impeller cleaning based on particulate load in your environment to maintain rated airflow performance over the 67,000-hour service life.
