Mars Hydro 6" Filter Kit CP Thermostat Controller | 402 CFM 32dB

Precision Control in Any Space

Uncontrolled environmental drift is the most expensive problem in a sealed cultivation enclosure — and the most invisible. Temperature climbs two degrees past threshold, humidity stalls in the canopy layer, and the fan running at a fixed speed does nothing because no one programmed it to respond. The operator walks in the next morning to a compromised environment, a saturated filter that never received adequate airflow, and a cycle that underperformed for reasons that never show up on a single data point. The enemy is not equipment failure — it is equipment that operates without feedback, without triggers, and without the ability to act on what the environment is actually doing.

After deployment, the enclosure runs on logic rather than assumption. The thermostat controller reads ambient temperature and humidity continuously, fires the fan at the appropriate speed tier when either parameter crosses a defined threshold, and logs the event. Odor is scrubbed at the source before it reaches the exhaust path. Airflow is never running harder than necessary, which means the filter media lasts longer and the motor draws only the wattage the environment actually demands. The operator sets the parameters once, locks the controller, and the system executes without further input.

The mechanism behind that outcome is a PWM-controlled EC motor operating at 3000 ±10% RPM, moving 402 CFM through a 6-inch duct path at a static pressure rating of 419 ±10% Pa — sufficient to maintain negative pressure in enclosures up to 5x5 ft against realistic duct resistance. The motor draws 62 W ±5% at a rated current of 0.94A MAX across 110–240 VAC at 50/60 Hz, making it compatible with standard U.S. single-phase circuits without a step-down transformer. The carbon filter uses 1050+ activated charcoal imported from Australia, packed behind a mesh with 53% open area to minimize restriction while maximizing contact time with VOC-laden air. The thermostat controller provides 10-speed PWM adjustment, high/low temperature and humidity alarm triggers, a timing schedule function, environment monitoring, controller lockout, calibration mode, and screen brightness modification — a full automation stack in a single control unit. In practical terms, the Mars Hydro 6" Filter Kit CP delivers 402 CFM of scrubbed, controlled airflow across enclosures up to 5x5 ft at 62 W ±5% on a standard 110–240 VAC circuit.

Where This Belongs (and Doesn't)

Electrical and HVAC note: This unit is rated for 110–240 VAC single-phase circuits. All duct connections, mounting hardware, and electrical hookups must comply with applicable local codes. Consult a licensed electrician or HVAC technician before integrating into any fixed building infrastructure. IP44 rating provides protection against solid objects greater than 1mm and water splashing from any direction — it does not constitute a submersion or wash-down rating.

How It Works

The airflow path begins at the carbon filter inlet. The filter housing contains 1050+ activated charcoal sourced from Australia, packed behind a mesh structure with 53% open area. That open-area ratio is the balance point between restriction and contact time — too restrictive and the motor works against back-pressure; too open and VOC-laden air bypasses the media. At 53%, the filter presents a manageable resistance profile for the EC motor while ensuring adequate dwell time for odor compound adsorption.

Air exits the filter and enters the 6-inch inline fan housing, where the PWM-controlled EC motor with mix-flow design accelerates it through the duct path. The mix-flow impeller geometry combines axial and centrifugal airflow characteristics, which is why the unit achieves 402 CFM at 3000 ±10% RPM while maintaining a static pressure rating of 419 ±10% Pa — a combination that sustains negative pressure in the enclosure even as duct length and bends add resistance. The motor operates across 110–240 VAC at 50/60 Hz, drawing 62 W ±5% at a maximum rated current of 0.94A. Noise output at operating speed is 32 dB-A. The IP44 enclosure rating protects internal motor components from particulate and incidental moisture contact.

The thermostat controller closes the automation loop. It monitors ambient temperature and humidity in real time and executes fan speed changes via PWM signal when user-defined thresholds are crossed — high temperature trigger, low temperature trigger, high humidity trigger, or low humidity trigger. The operator configures 10 discrete speed steps, sets a timing schedule for baseline operation, and can engage controller lockout to prevent parameter drift from unauthorized adjustments. Calibration mode allows the operator to offset sensor readings against a reference instrument. Screen brightness is adjustable for low-light environments. The controller also provides audible and visual alarms when environmental parameters exceed set limits, giving the operator an out-of-band alert without requiring continuous monitoring. In practical terms, the Mars Hydro 6" Filter Kit CP delivers automated, threshold-triggered airflow at 402 CFM through a 6-inch duct path, with full odor scrubbing and 10-speed PWM control, drawing 62 W ±5% at 0.94A MAX on a 110–240 VAC circuit.

System Integration

• Duct Compatibility: 6-inch duct collar; connects directly to standard 6-inch flexible or rigid duct. The included 25-ft PVC thermoplastic flexible duct tube covers most single-enclosure configurations without additional ducting.
• Electrical Integration: 110–240 VAC dual-voltage input at 50/60 Hz allows direct connection to standard U.S. outlets without a transformer. Maximum draw of 0.94A at 62 W ±5% presents minimal load on a standard 15A or 20A circuit.
• Controller Wiring: The thermostat controller connects to the EC motor via the included harness. No external relay or speed controller is required — the PWM signal is native to the EC motor architecture.
• Mounting: Two adjustable hanging straps and three duct clamps are included. The fan and filter can be suspended from tent cross-bars or overhead structural members within the rated load capacity of the mounting point.
• Scalability: For multi-enclosure deployments, each enclosure requires its own fan/filter/controller unit. There is no shared-controller or daisy-chain architecture for this product line — each unit operates as an independent closed-loop system.

Facility Integration Data

The table below provides fleet-level electrical load and unit-count reference data for operators deploying multiple enclosures under a single facility electrical plan.

Current figures are calculated at 0.94A MAX per unit. Actual draw will vary with speed setting and static pressure load. Circuit sizing must comply with NEC 80% continuous load rule and applicable local codes. Consult a licensed electrician for multi-unit circuit planning.

Operator Field Notes

• Controller Lockout: Engage the lockout function after finalizing speed and threshold parameters. This prevents accidental parameter changes during routine access to the enclosure and is particularly important in multi-operator environments.
• Calibration Offset: The calibration mode allows the operator to align the onboard sensor reading with a reference thermometer or hygrometer. Perform this calibration at initial setup and after any significant change in ambient conditions outside the enclosure.
• Filter Orientation: The carbon filter is designed to be installed on the intake side of the fan — air enters the filter, passes through the activated charcoal bed, and exits through the fan into the duct. Reversing this orientation reduces scrubbing efficiency and increases motor back-pressure.
• Duct Run Management: The included 25-ft flexible duct tube provides maximum routing flexibility, but each 90-degree bend adds equivalent resistance. Minimize bends and keep total equivalent duct length within the static pressure rating of 419 ±10% Pa to maintain rated CFM output.
• Alarm Response Protocol: When a temperature or humidity alarm triggers, verify the sensor reading against an independent reference before adjusting set points. Sensor drift is possible in high-humidity environments; use calibration mode to correct before modifying threshold parameters.
• Hanging Strap Load: The two included adjustable hanging straps are rated for the combined weight of the fan and filter assembly. Do not use them to support additional equipment or duct weight beyond the fan/filter unit itself.
