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 across every harvest cycle as environmental variance. Fixed-speed motors run at full draw regardless of room demand, generating heat, noise, and energy waste around the clock. When temperature climbs two degrees above setpoint and the fan has no mechanism to respond, the room drifts. That drift compounds across the canopy, across the week, across the quarter. The result is not a catastrophic failure — it is a slow, invisible erosion of consistency that separates manufactured inventory from variable output.

After deployment, the facility operates on a different logic. The atmospheric control layer responds to actual room conditions rather than a fixed dial position. Airflow modulates automatically across ten discrete speed increments, holding the environment within the parameters your production protocol demands. The motor runs quietly enough that it disappears from the operational environment — no vibration transmitted through the structure, no noise floor that masks equipment alerts. Maintenance windows are planned, not reactive, because the mechanical platform is engineered to outlast the grow cycles it serves.

The mechanism behind that outcome is an EC-powered motor controlled via PWM (Pulse Width Modulation), which enables smooth, precise RPM modulation down to extremely low speeds without generating motor noise — a capability that AC motor platforms cannot replicate. The CLOUDLINE A8 moves 724 CFM through an 8-inch duct at a maximum draw of 190 watts, sustaining 746 Pa of static pressure to maintain airflow through fully loaded ducting configurations. Dual ball bearings carry an L10 life expectancy of 67,000 hours. The IP44 rating provides resistance to dust and liquid ingress, qualifying the unit for sealed cultivation environments where humidity and particulate exposure are continuous. The included wired 10-speed controller ships with the unit; the platform also integrates with B-Series Temperature Controllers and all CLOUDLINE Series smart controllers within the UIS ecosystem. In practical terms, the CLOUDLINE A8 delivers 724 CFM at 42 dBA across an 8-inch duct circuit at a maximum draw of 190 watts.

Where This Belongs (and Doesn't)

Minimum infrastructure requirement: A dedicated circuit capable of supporting 190W continuous draw. Duct runs must be sized for 8-inch connections. HVAC load calculations should account for the fan's heat contribution and the exhaust volume it removes from the conditioned space.

Infrastructure Note: The CLOUDLINE A8 operates on 100-240V AC at 50/60Hz, making it compatible with standard U.S. commercial electrical infrastructure. Cord length to controller and to plug are each 72 inches (6 feet). Mounting is supported in horizontal or vertical positions. Mounting hole-to-hole distance is 3.54 x 1.96 in. (9.0 x 5.0 cm); screw hole diameter is 0.217 in. (0.55 cm). Verify structural anchor points before installation.

How It Works

The CLOUDLINE A8 is built around an EC (electronically commutated) motor — a motor architecture that accepts direct PWM (Pulse Width Modulation) speed commands rather than operating at a fixed AC frequency. This distinction is operationally significant: where a standard AC motor runs at one speed and generates motor noise at low RPM, the EC motor in the CLOUDLINE A8 modulates smoothly across ten discrete speed settings, maintaining stable airflow without the harmonic vibration that characterizes fixed-speed platforms. At maximum output, the unit delivers 724 CFM through an 8-inch duct at 42 dBA — a noise floor low enough that the fan does not compete with environmental monitoring equipment or staff communication in the facility.

The mixed flow design of the impeller and blade assembly — housed in a detachable motor box — combines axial and centrifugal airflow characteristics, enabling the unit to sustain 746 Pa of static pressure. This matters in real ducting configurations: long runs, carbon filter resistance, and multiple duct bends all increase static pressure load. A fan that cannot maintain pressure under load reduces airflow at the point of delivery, creating dead zones in the ventilation circuit. The CLOUDLINE A8's static pressure rating ensures that rated CFM is delivered at the duct termination, not just at the fan inlet. Dual hydrodynamic wind circles in the motor housing further optimize airflow efficiency through the unit. The plastic mounting base mechanically decouples the fan body from the mounting structure, attenuating vibration transmission that would otherwise add to the ambient noise floor. Dual ball bearings — rated at an L10 life expectancy of 67,000 hours — support mounting in any direction, horizontal or vertical, without bearing load compromise. The IP44 rating qualifies the unit for environments with dust and liquid exposure. The motor box is detachable from the mounted frame, enabling cleaning and maintenance without removing the unit from the duct circuit. In practical terms, the CLOUDLINE A8 delivers 724 CFM at 42 dBA through an 8-inch duct at 190 watts maximum draw, with 746 Pa static pressure capacity and a 67,000-hour bearing life expectancy.

System Integration

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

• Controller Compatibility: Ships with an included wired 10-speed fan controller. Also compatible with B-Series Temperature Controllers and all CLOUDLINE Series smart controllers within the UIS ecosystem — verify controller firmware version with AC Infinity before pairing.
• Duct Sizing: Requires 8-inch duct connections at both inlet and outlet. Reducers or adapters will reduce effective CFM and increase static pressure load — account for this in duct design.
• Electrical: 100-240V AC, 50/60Hz, 190W maximum draw. Verify available circuit capacity before installation. Cord length to controller and to plug are each 72 inches (6 feet) — plan mounting position relative to outlet and controller location accordingly.
• Mounting Structure: Supports horizontal or vertical mounting. Mounting hole-to-hole distance is 3.54 x 1.96 in. (9.0 x 5.0 cm); screw hole diameter is 0.217 in. (0.55 cm). Structural anchor points must support the unit's weight and any duct tension load.
• HVAC Load: At 190W maximum draw, the unit contributes approximately 648 BTU/hr of heat to the space. Account for this in room HVAC sizing, particularly in sealed environments where heat accumulation is a primary control variable.

Operator Field Note

• Weight and Structural: Unit dimensions are 12.20 x 10 x 9.37 in. (31 x 25.4 x 23.8 cm). Mounting hole-to-hole distance is 3.54 x 1.96 in. (9.0 x 5.0 cm); screw hole diameter is 0.217 in. (0.55 cm). Verify that mounting anchors and duct hangers are rated for the combined weight of the unit and any attached ducting.
• Electrical: Maximum power draw is 190W at 100-240V AC, 50/60Hz. At 120V, this represents approximately 1.58A continuous draw. Verify available circuit capacity and do not share circuits with high-inrush equipment without load calculation review.
• Cord Management: Cord length to controller is 72 inches (6 feet); cord length to plug is 72 inches (6 feet). Plan mounting position to ensure both runs reach their termination points without extension cords, which can introduce voltage drop at the controller.
• Mounting Orientation: Dual ball bearings support horizontal or vertical mounting. The plastic mounting base is designed to attenuate vibration transmission — do not substitute rigid metal mounting hardware, as this will increase structure-borne noise.
• Maintenance Access: The motor box containing the impeller and blades is detachable from the mounted frame. Schedule periodic cleaning intervals based on particulate load in the environment — the IP44 rating provides ingress resistance, not immunity. Detach the motor box without removing the unit from the duct circuit to minimize downtime.
• Environmental Setpoints: The IP44 rating qualifies this unit for dust and liquid-exposed environments. Do not operate in conditions exceeding the rated environmental resistance or in applications requiring IP65+ submersion protection.
