Precision Control in Any Space

Every unfiltered intake port in a ventilation circuit is a liability operating in silence. Dust accumulates on fan blades, reducing motor efficiency and shortening service intervals. Lint and particulate matter migrate through ductwork, coating surfaces that were never designed to be cleaned. Odors cycle back through the system unchecked. The equipment you invested in to move air precisely is being undermined at the point of entry — and the degradation is gradual enough that most operators don't register the cost until a component fails or air quality measurements fall outside acceptable range. Guesswork and equipment that fights you are not abstract problems; they are the measurable consequence of an intake circuit with no filtration architecture.

After deployment, the intake side of your ventilation circuit operates as a controlled boundary. Particulate contamination stops at the filter media before it enters the duct run. Fan motors maintain rated performance because blade surfaces stay clean. Air quality in the controlled environment remains consistent across operating cycles because the intake is no longer an unmanaged variable. Maintenance intervals become predictable — filter inspection and replacement on a defined schedule rather than reactive cleaning triggered by equipment degradation. The ventilation system performs the way it was specified to perform, from the first day of operation through the full service life of the installation.

The mechanism behind that outcome is a sealed steel enclosure built to ductwork-grade tolerances. The AC-AFB6 is constructed from 1mm thick SPCC cold-rolled steel with aluminum duct flanges, accepting a standard 12 x 20 x 1 pleated filter media that captures particles in the 0.3–1.0 micron range at 90% filtration efficiency. A hinge-sealed door with slide lock mechanism provides access to the inner chamber for filter service, while a soft neoprene door layer creates an airtight seal that prevents bypass contamination. The 5.78 in. (14.7 cm) duct opening is sized for direct integration with CLOUDLINE S6 and CLOUDLINE T6 inline fans, supporting airflow from 182–272 CFM at the minimum operating range up to 800 CFM at maximum throughput. In practical terms, the AC Infinity Air Filter Box 6" delivers 90% particulate capture across the 0.3–1.0 micron range at airflow rates up to 800 CFM through a 5.78-inch duct interface with a total enclosure footprint of 23.46 x 8.42 x 11.73 in.

Where This Belongs (and Doesn't)

The AC-AFB6 is a passive filtration enclosure. It does not generate airflow. Proper installation requires a compatible inline fan (CLOUDLINE S6 or CLOUDLINE T6) to drive air through the filter media. All ductwork connections must comply with applicable local mechanical and building codes. Consult a licensed HVAC professional for installations involving pressurized systems or code-regulated duct circuits.

How It Works

The AC-AFB6 operates as a sealed filtration stage inserted into the intake side of a 6-inch duct circuit. Incoming air enters through the 5.78 in. (14.7 cm) duct opening, passes through the 12 x 20 x 1 pleated filter media seated in the 1-inch steel filter slot, and exits through the outlet flange into the connected inline fan. The filter media captures particles in the 0.3–1.0 micron range — including dust, dirt, lint, and welding fumes — at 90% filtration efficiency, preventing that particulate load from reaching the fan motor, duct interior, or the controlled environment downstream. The aluminum duct flanges, measuring 3.21 in. (8.2 cm) in flange length, provide secure mechanical connection to standard 6-inch ductwork on both the intake and outlet sides.

The enclosure body is fabricated from 1mm thick SPCC cold-rolled steel with a matte black finish, providing structural rigidity and resistance to the temperature and humidity conditions present in active ventilation circuits. The hinge-sealed access door uses a slide lock mechanism to secure the inner chamber during operation. A soft neoprene layer on the door creates an airtight seal at the chamber boundary, preventing bypass air — and the particulate it carries — from entering the filter box without passing through the filter media. Filter service is performed by releasing the slide lock, opening the hinged door, and removing the 12 x 20 x 1 filter from the 1-inch steel retention slot. No tools are required for routine filter replacement. The total enclosure dimensions of 23.46 x 8.42 x 11.73 in. (59.6 x 21.4 x 29.8 cm) accommodate standard duct routing geometry in mechanical spaces with limited clearance. In practical terms, the AC Infinity Air Filter Box 6" processes airflow from 182 CFM at minimum operating range to 800 CFM at maximum throughput through a sealed steel enclosure measuring 23.46 x 8.42 x 11.73 in., with tool-free filter access via a neoprene-sealed slide lock door.

System Integration

• Compatible Inline Fans: Engineered for direct integration with AC Infinity CLOUDLINE S6 and CLOUDLINE T6 — the 5.78 in. (14.7 cm) duct opening aligns with the 6-inch duct interface on both fan models without adapters
• Ductwork Compatibility: Aluminum flanges with 3.21 in. (8.2 cm) flange length connect to standard 6-inch flexible or rigid duct using conventional duct clamps or tape — no proprietary fittings required
• Filter Media Sourcing: Accepts any standard 12 x 20 x 1 pleated filter — a commodity size available through HVAC supply channels, reducing dependency on proprietary replacement media
• Airflow Range Alignment: The 182–800 CFM operating range covers the full output spectrum of compatible CLOUDLINE 6-inch fan models, ensuring the filter box does not become a restriction bottleneck at any fan speed setting
• Enclosure Footprint: At 23.46 x 8.42 x 11.73 in. (59.6 x 21.4 x 29.8 cm), the unit is sized for installation in mechanical chases, equipment rooms, and inline duct runs where space allocation is a design constraint

Operator Field Notes

• Filter Replacement Interval: Establish a documented inspection schedule based on the particulate load of your intake environment — facilities with higher dust or lint concentrations will require shorter replacement intervals than the filter media's maximum service life suggests under clean-air conditions
• Bypass Seal Verification: After each filter replacement, confirm the slide lock is fully engaged and the neoprene door seal is seated without gaps — any bypass path around the filter media defeats the 90% capture efficiency rating
• Intake Positioning: Mount the unit so the access door is reachable without disconnecting ductwork — the slide lock mechanism is designed for in-place filter service, and installations that require duct disassembly for filter access eliminate that operational advantage
• Airflow Restriction Monitoring: A loaded filter increases static pressure in the duct circuit. If your CLOUDLINE fan is operating at maximum speed to maintain target airflow, treat that as a filter service indicator rather than a fan performance issue
• Filter Media Standardization: The 12 x 20 x 1 filter size is a standard HVAC dimension. Sourcing replacement media through HVAC supply channels rather than retail outlets reduces per-filter cost at volume and ensures consistent media availability across multiple facility locations
• Flange Connection Integrity: Inspect aluminum flange connections at each filter service interval — the 3.21 in. (8.2 cm) flange length provides adequate engagement for duct clamps, but vibration from the connected inline fan can loosen connections over extended operating periods
