Mars Hydro iFresh 6" Complete Fan Kit | 402 CFM, 32 dBA EC Motor

Precision Control in Any Space

Every uncontrolled grow environment carries a hidden operational tax. When airflow is inconsistent — when a fan runs at a fixed speed regardless of actual temperature and humidity conditions, when carbon filtration is undersized or mismatched, when cables from three separate controllers snake across every available surface — the cost shows up in the canopy before it shows up on a spreadsheet. Odor bleed, heat stratification, and VPD swings are not random events. They are the predictable output of equipment that was never designed to work as a system. The enemy is not any single component failure; it is the accumulated variance that comes from assembling a ventilation stack from incompatible parts and hoping the numbers average out.

After deployment, the environment inside a sealed cultivation space stops being a variable and starts being a parameter. Air exchange runs at a measured 402 CFM, scrubbed through Australian activated charcoal before it exits the enclosure. Fan speed responds to actual conditions rather than a fixed dial position. The iConnect expansion path means that when the operation is ready for automated VPD monitoring and app-based climate triggers, the hardware is already in place — no retrofit, no second fan purchase. The result is a cultivation environment where temperature, humidity, and odor are managed outputs, not managed surprises.

The mechanism behind that outcome is a PWM-controlled EC motor running at 3,000 RPM (±10%) against a static pressure rating of 419 Pa (±10%), delivering 402 CFM / 682 m³/h through a 6-inch duct at a measured noise floor of 32 dBA. Input power is rated at 62W (±5%) with a maximum draw of 0.94A across a universal voltage range of AC 110–240V at 50/60 Hz. The IP44 enclosure rating protects motor and electronics across an operating temperature range of -20°C to 60°C (-4°F to 140°F). The USB-based controller architecture eliminates the dedicated power brick and reduces cable clutter at the controller position. The iFresh MarsPro Add-On Pack (MH-MARSPRO-ADDON, sold separately or included in the Pro configuration) adds the iConnect controller and integrated temperature/humidity sensor, enabling MarsPro APP integration with alarm thresholds, climate-triggered speed adjustments, and loop timer scheduling. In practical terms, the Mars Hydro iFresh 6" Kit delivers 402 CFM of filtered, speed-controlled airflow at a 32 dBA noise floor, drawing 62W at up to 0.94A, with a clear upgrade path to full app-based environmental automation.

Where This Belongs (and Doesn't)

Electrical installation must comply with all applicable local codes. Duct routing, static pressure load calculations, and enclosure penetrations should be reviewed by a qualified HVAC or electrical professional before permanent installation. This unit is rated IP44 and is not suitable for direct water exposure or outdoor unenclosed deployment.

How It Works

The iFresh 6" fan unit is built around a PWM-controlled EC (electronically commutated) motor. Unlike AC motors that operate at a fixed speed determined by line frequency, the EC motor accepts a PWM signal that modulates rotor speed continuously across the full operating range. This means speed adjustments are not stepped — they are proportional and precise, with the motor maintaining 3,000 RPM (±10%) at rated load against a static pressure ceiling of 419 Pa (±10%). EC motor architecture also produces measurably lower heat output and longer service life compared to equivalent AC motor designs, which is operationally relevant in sealed environments where motor heat contributes to ambient temperature load.

The USB-based controller design consolidates speed control and (in the Pro configuration) app connectivity through a single cable interface, eliminating the separate power supply and dedicated wall outlet that conventional speed controllers require. In the Standard configuration (MH-6IN-IFRESH-STD), the fan ships with manual PWM speed control. Upgrading to app-based automation requires the iFresh MarsPro Add-On Pack (MH-MARSPRO-ADDON), which adds the iConnect controller and an integrated temperature and humidity sensor. Once the Add-On Pack is installed, the MarsPro APP enables remote speed adjustment, alarm thresholds for temperature and humidity excursions, climate-triggered fan speed responses, and loop timer scheduling — all without replacing the fan unit itself.

The included carbon filter uses Australian activated charcoal media in a refillable housing. Refillable construction means the filter body does not need to be replaced when media is exhausted — only the charcoal is replenished, reducing per-cycle consumable cost. The filter is rated for 6-inch duct connections and is sized to match the fan's 402 CFM output without creating a static pressure bottleneck. The complete kit (MH-6IN-IFRESH-KIT) includes the inline fan, carbon filter, flexible ducting, three steel hoops, four 5-gallon grow bags, a grow net, a 6-inch clip fan, 6-inch scissors, glasses, two ventilation mesh covers, and two grow tent corner brackets — all components confirmed in source data. In practical terms, the Mars Hydro iFresh 6" system moves 402 CFM / 682 m³/h at 32 dBA through a 6-inch duct, drawing 62W at up to 0.94A, with a refillable carbon filter and a clear hardware path from manual PWM control to full app-based environmental automation.

Operator Field Notes

• Standard vs. Pro Configuration: The Standard version (MH-6IN-IFRESH-STD) ships without the iConnect controller and sensor. App control features require either the Pro version or the separately purchased iFresh MarsPro Add-On Pack (MH-MARSPRO-ADDON). If you purchase Standard now, the Add-On Pack upgrade path remains available post-deployment.
• Static Pressure Budget: Rated static pressure is 419 Pa (±10%). Extended duct runs, multiple bends, or heavily loaded carbon filter media will reduce effective static pressure margin. Calculate total system resistance before finalizing duct layout.
• Carbon Filter Media: The refillable housing accepts replacement Australian activated charcoal media. Track media saturation by odor breakthrough, not by a fixed calendar interval — replacement frequency depends on canopy load and air exchange rate.
• Noise Floor Context: 32 dBA is measured at rated operating conditions. Actual noise level in a sealed enclosure will vary with mounting method, duct tension, and fan speed setting. Flexible duct connections and vibration-isolating mounting hardware reduce transmitted noise to adjacent spaces.
• Electrical Load Planning: Maximum rated current is 0.94A at AC 110–240V. At 110V, this represents approximately 103W maximum draw; at 240V, approximately 226W maximum draw. Size circuit protection accordingly and do not share circuits with high-inrush equipment without load calculation review.
• IP44 Limitation: IP44 protects against splashing water from any direction but is not rated for direct water jets or submersion. Do not mount in positions where condensate or irrigation runoff can pool against the motor housing.
