Precision Control in Any Space

Uncontrolled particulate infiltration is one of the most overlooked sources of operational loss in a sealed cultivation environment. Dust, lint, and airborne debris enter through unfiltered duct connections, coat canopy surfaces, clog equipment intakes, and introduce contamination vectors that compound over every production cycle. The cost is rarely visible on a single day — it accumulates in degraded air quality, increased equipment maintenance intervals, and the kind of inconsistent results that operators attribute to everything except the atmospheric system that was never properly sealed. When the intake path is uncontrolled, every other investment in environmental precision is undermined at the source.

After deploying a properly specified inline filtration enclosure, the atmospheric circuit closes. Fresh air enters the space pre-filtered, particulate load on canopy surfaces drops, and the inline fan operates against a clean, consistent static pressure profile rather than a variable one. Maintenance intervals extend because equipment is no longer processing contaminated airstreams. The atmospheric ecosystem functions as a designed system rather than a collection of components working against each other — and the operator stops troubleshooting air quality as a variable entirely.

The mechanism behind that outcome is a 1mm thick SPCC steel enclosure with aluminum duct flanges, a 7.79 in. (19.8 cm) duct opening, and a pre-installed 14 x 20 x 1 in. pleated high-efficacy filter rated to trap 90% of particles in the 0.3–1.0 micron range. The hinge-sealed door with slide lock mechanism allows filter access without disconnecting ductwork, and the neoprene door seal maintains an airtight chamber boundary during operation. Airflow range spans 402–604 CFM at minimum operating conditions up to 1600 CFM maximum, with the inline installation geometry engineered to introduce little to no measurable restriction into the duct run. Compatibility is validated for CLOUDLINE S8 and CLOUDLINE T8 inline fans, which provide the high static pressure profile required to maintain rated airflow through the filter media. In practical terms, the AC Infinity Duct Air Filter Box 8" delivers 90% particulate trapping at 0.3–1.0 microns across a 402–1600 CFM airflow envelope within a 22.51 x 11.57 x 13.93 in. (57.1 x 29.4 x 35.4 cm) enclosure footprint.

Where This Belongs (and Doesn't)

This unit is a passive inline filtration enclosure. It does not generate airflow independently. All airflow is driven by a compatible inline fan — CLOUDLINE S8 or CLOUDLINE T8 recommended. Do not install in duct runs where static pressure requirements exceed the rated capacity of the paired fan. This unit is not rated for high-humidity condensing environments or direct outdoor exposure. Consult your facility HVAC design before integrating into pressurized plenum systems.

How It Works

The AC Infinity Duct Air Filter Box 8" operates as a sealed inline filtration chamber inserted into an 8-inch duct run. Airflow driven by a compatible inline fan — CLOUDLINE S8 or CLOUDLINE T8 — enters the enclosure through the 7.79 in. (19.8 cm) aluminum duct flange, passes through the pre-installed 14 x 20 x 1 in. pleated high-efficacy filter, and exits through the opposing flange into the downstream duct run. The filter media captures 90% of particles in the 0.3–1.0 micron range, including dust, dirt, lint, and odor-carrying particulates. The enclosure body is constructed from 1mm thick SPCC cold-rolled steel with a powder-coated matte black finish, and the duct flanges are aluminum with a 3.23 in. (8.2 cm) flange length providing secure duct connection points at both inlet and outlet.

The hinge-sealed door with slide lock mechanism is the serviceability feature that separates this enclosure from fixed-housing alternatives. The door opens to expose the full interior chamber without requiring duct disconnection or enclosure removal. A soft neoprene seal layer on the door perimeter creates an airtight boundary when closed, preventing bypass airflow around the filter media and ensuring that all air passing through the enclosure is processed by the filter. The slide lock secures the door against vibration and pressure differentials generated during fan operation. The inline installation geometry is engineered to introduce little to no airflow restriction, allowing the paired fan to maintain its rated CFM output across the 402–1600 CFM operating range. In practical terms, the AC Infinity Duct Air Filter Box 8" processes up to 1600 CFM through a 90%-efficient filter at 0.3–1.0 microns within a 22.51 x 11.57 x 13.93 in. (57.1 x 29.4 x 35.4 cm) enclosure that accepts standard 14 x 20 x 1 in. pleated replacement filters.

System Integration

• Fan Pairing (Required): Integrate with CLOUDLINE S8 or CLOUDLINE T8 inline fans. High static pressure fan selection is mandatory — insufficient static pressure will reduce airflow through the filter media below the rated 402–1600 CFM range and compromise filtration efficiency.
• Duct Sizing: Designed for 8-inch duct runs. The 7.79 in. (19.8 cm) duct opening and 3.23 in. (8.2 cm) aluminum flanges connect to standard 8-inch flexible or rigid ductwork. Verify duct diameter consistency across the full run before installation.
• Filter Replacement Cycle: The pre-installed 14 x 20 x 1 in. pleated filter is a consumable. Establish a scheduled replacement interval based on particulate load in the operating environment. Standard 14 x 20 x 1 in. pleated filters are available through HVAC supply channels.
• Atmospheric Ecosystem Positioning: This enclosure functions as the particulate control node in a broader atmospheric control circuit. Pair with AC Infinity CLOUDLINE fan controllers for automated deployment of fan speed and scheduling, completing the UIS (Unified Inline System) integration from intake filtration through exhaust management.
• Mounting Orientation: Inline installation in horizontal or vertical duct runs. Confirm door access clearance of at least the enclosure depth (13.93 in. / 35.4 cm) on the door-side face before finalizing mounting position.

Operator Field Notes

• Static Pressure Matching Is Non-Negotiable: The filter media introduces resistance into the duct run. Pairing this enclosure with an undersized or low-static-pressure fan will result in reduced CFM through the filter and degraded filtration efficiency. CLOUDLINE S8 and CLOUDLINE T8 are the validated pairings — do not substitute without verifying static pressure curves.
• Door Clearance Before Mounting: The slide lock door requires unobstructed access on the door-side face of the enclosure. Measure and confirm at least 13.93 in. (35.4 cm) of clearance in the door-swing direction before finalizing mounting position. Inaccessible doors defeat the serviceability advantage of this design.
• Neoprene Seal Inspection at Each Filter Change: The neoprene door seal is the airtight boundary between the filtered and unfiltered sides of the enclosure. Inspect the seal for compression set, tears, or debris accumulation at every filter replacement. A compromised seal allows bypass airflow that reduces effective filtration efficiency below the rated 90%.
• Filter Load Monitoring: In high-particulate environments — facilities with elevated dust, lint, or process-generated airborne debris — filter loading will occur faster than in clean-air environments. Establish a baseline pressure differential check across the enclosure at installation and monitor for increased restriction as an indicator of filter saturation.
• Flange Connection Integrity: The 3.23 in. (8.2 cm) aluminum flanges require secure duct tape or clamp connection to the duct run at both inlet and outlet. Loose flange connections create bypass leakage points that reduce both filtration efficiency and fan-driven CFM delivery to the space.
• Replacement Filter Standardization: The 14 x 20 x 1 in. pleated filter format is a standard HVAC size. Procure replacement filters in bulk to reduce per-unit cost and ensure filter changes are not deferred due to supply availability.
