Precision Control in Any Space

Every uncontrolled grow environment has the same silent adversary: thermal and odor variance that compounds over time. When airflow is fixed or manually approximated, canopy temperatures drift, vapor pressure deficit swings outside target range, and odor containment fails at the worst possible moment — during inspection, during harvest, during the exact window when consistency matters most. AC motor fans run at a single speed or cycle on and off with no feedback loop, burning energy and generating noise while delivering airflow that is either too aggressive or completely inadequate for the current stage. The filter gets overwhelmed because the fan never modulates. The fan runs loud because the motor was never designed for variable demand. The operator adjusts manually, then forgets, then adjusts again — and the environment never stabilizes.

After deploying the iFresh 6" Kit, the environment operates on a different logic. Airflow is dialed to the exact CFM the space requires at each growth stage — lower during early vegetative development to preserve humidity, higher during late flower to manage transpiration load and odor pressure. The carbon filter handles odor at the source, not at the perimeter. The room holds negative pressure without constant manual intervention. The operator sets the speed controller once, confirms the environment is stable, and moves on. The system runs quietly enough that it does not register as background noise in adjacent spaces, and the EC motor sustains that output without the thermal degradation that shortens AC motor service life.

The mechanism behind that stability is a PWM-controlled EC motor spinning at 3,000 RPM (±10%) and moving 402 CFM (682 m³/h) through a 6-inch duct path at 419 Pa (±10%) of static pressure — enough to overcome real-world duct resistance without oversizing the system. Input power is 62W (±5%) at a rated current of 0.94A maximum, operating on 110–240VAC at 50/60Hz, which means the kit runs on standard North American circuits without a dedicated circuit upgrade. Noise output is 32 dBA, measured at operating speed — below the threshold that creates compliance issues in shared-wall facilities. The IP44 rating protects the motor housing against particulate ingress and moisture contact consistent with humid cultivation environments. The included refillable carbon filter uses Australian activated charcoal, and the speed controller provides manual PWM adjustment without requiring any additional hardware at the point of purchase. In practical terms, the Mars Hydro iFresh 6" Kit delivers 402 CFM of PWM-regulated airflow through a 6-inch duct path at 62W input and 32 dBA operating noise, with full IP44 environmental protection.

Where This Belongs (and Doesn't)

Disclaimer: This kit is designed for low-voltage inline fan and passive carbon filtration applications. It is not a substitute for commercial HVAC infrastructure, building mechanical ventilation systems, or high-static-pressure industrial exhaust applications. All electrical connections must comply with applicable local codes. Consult a licensed electrician for any hardwired installation.

How It Works

The iFresh 6" Kit is built around an EC (electronically commutated) motor — a fundamentally different motor architecture than the AC induction motors found in commodity inline fans. EC motors use permanent magnet rotors and electronic commutation to convert input power to shaft rotation with significantly lower resistive losses. The practical result is a motor that runs cooler, draws less current at equivalent airflow outputs, and maintains consistent performance across its service life rather than degrading as winding resistance increases with thermal cycling. The PWM (pulse-width modulation) speed control interface allows the operator to vary motor speed continuously across the operating range rather than switching between fixed speed taps — which means airflow can be matched precisely to the current environmental demand without the on/off cycling that creates pressure spikes and noise events in fixed-speed systems.

At full rated speed, the motor turns at 3,000 RPM (±10%) and generates 419 Pa (±10%) of static pressure — the force that drives air through the duct run and carbon filter bed against real-world resistance. The 402 CFM (682 m³/h) airflow rating is the volume throughput at that static pressure, not a free-air measurement taken without load. Input power consumption is 62W (±5%) at a maximum rated current of 0.94A, operating on 110–240VAC at 50/60Hz. The wide voltage range means the kit is compatible with both standard 110V North American circuits and 240V configurations without a transformer or adapter. The IP44 motor housing rating provides protection against solid particle ingress (4mm and larger) and water splash from any direction — appropriate for the humidity levels present in active cultivation environments.

The carbon filter uses Australian activated charcoal, a source material recognized for high surface area per gram and consistent adsorption performance across the terpene and volatile organic compound (VOC) profiles generated during cultivation. The filter housing is refillable, which means the activated charcoal bed can be replaced without purchasing a new filter body — reducing per-cycle consumable cost and eliminating the disposal of structural filter components. The 25-foot flexible duct tube, three duct clamps, and two hanging straps included in the kit are sized and rated for the 6-inch duct diameter and the airflow velocity the fan generates at operating speed. The speed controller included in the standard kit provides manual PWM adjustment. App-based control — including remote adjustment, climate trigger automation, VPD monitoring, alarms, and loop timers — is available through the separately purchased iFresh Add-on Pack (iConnect controller and sensor), which connects via USB and upgrades the system without replacing any installed hardware. In practical terms, the Mars Hydro iFresh 6" Kit moves 402 CFM through a 6-inch duct path at 62W and 32 dBA, with an EC motor rated to 3,000 RPM and 419 Pa static pressure on any 110–240VAC circuit.

System Integration

• Duct Compatibility: Designed for 6-inch duct infrastructure. The included 25-foot flexible duct tube and three duct clamps are sized for the fan's 402 CFM output at operating static pressure.
• Electrical Requirements: 110–240VAC / 50/60Hz input at 0.94A maximum rated current — compatible with standard North American 15A circuits without a dedicated drop.
• Speed Control Integration: Manual PWM speed controller included in base kit. Upgrade to app-based control (remote adjustment, climate triggers, VPD monitoring, alarms, loop timers) via the separately purchased iFresh Add-on Pack (iConnect controller and sensor, USB-connected).
• Filter Maintenance Cycle: Refillable Australian activated charcoal filter body — replace the charcoal bed on a schedule matched to canopy size and odor load without replacing the filter housing.
• Mounting: Two hanging straps included. Fan and filter assembly designed for overhead inline duct mounting within the cultivation space or in an adjacent mechanical chase.

Adjust the per-kWh rate to match your facility's utility tariff for accurate cost modeling.

Operator Field Notes

• Speed Controller Scope: The included speed controller is a manual PWM device. It does not provide app connectivity, scheduling, or sensor integration out of the box. Those capabilities require the separately purchased iFresh Add-on Pack (iConnect controller and sensor).
• Static Pressure Rating: The 419 Pa (±10%) static pressure rating is the force available to overcome duct resistance. Long duct runs, multiple bends, or undersized duct connectors will reduce effective CFM below the 402 CFM rated output. Size your duct path accordingly.
• Filter Refill Interval: The refillable carbon filter body eliminates the need to replace the entire filter assembly, but the activated charcoal bed has a finite adsorption capacity. Replacement interval depends on canopy size, terpene load, and airflow rate — monitor odor breakthrough as the primary indicator for charcoal replacement.
• Voltage Range: The 110–240VAC / 50–60Hz input range covers standard North American circuits. Verify your outlet configuration before installation. The 0.94A maximum rated current is well within standard 15A circuit capacity even in multi-unit configurations sharing a circuit.
• IP44 Limitation: IP44 protects against splash water and 4mm+ particulate ingress. It is not rated for direct water jet exposure or submersion. Do not install the fan motor housing in a position where it receives direct irrigation spray or condensate drip.
