A manifold routes outdoor air through furnace ducting while exhausting indoor stale air, improving ventilation without a separate HRV.

A movable cone damper in a perforated distribution pipe enables fast airflow adjustment, full shutoff, lower noise, and easier cleaning.

A rectangular modular duct with insulation and flange joints avoids field welding, contains hazardous exhaust, and fits standard ceiling spaces.

Spin forming and radial expansion create stronger HVAC duct connectors from thicker metal while enabling secure single-person assembly.

Broken flange sections let ducts nest concentrically without edge deformation, cutting storage space and easing transport.

Mechanically coupled outside-air and bypass flaps keep combustion air flowing while preventing wall-duct cooling in airtight homes.

Separating the fabric air duct into tracked upper and lower sheets simplifies installation, removal, washing, and airflow customization.

A controller returns the airflow flap to a reference position before swing, preventing out-of-range motion after manual mishandling.

Dual-sided mounting features let one HVAC duct mount secure UV lamps or odor bars on interior or exterior walls without losing attachment flexibility.

A pressure-responsive zone damper bleeds excess conditioned air to control duct static pressure without bypass dampers, cutting noise and energy use.

Ratchet-and-pawl flange clips secure an HVAC floor diffuser from above, simplifying installation, adjustment, and relocation.

A distribution box and under-seat duct route conditioned air to both sides of a work vehicle cab without sacrificing interior space.

A rotatable louver closes the outdoor unit discharge port when idle to block sand and other debris, while reopening for normal air discharge.

A one-piece coupling sleeve connects corrugated pipes to different housings, cutting parts count and simplifying secure assembly.

An adjustable trap door bleeds supply air from the diffuser conduit to cut ground-level draughts while preserving temperature homogeneity.

Changing duct length and cross-section tunes Helmholtz resonance, letting image forming equipment absorb different noise frequencies at lower cost.

A drop-down sliding and swinging ceiling air terminal avoids hose damage and beam interference during ship cabin installation.

A helical element and closely spaced ridges let a single-layer aluminum duct stay rigid when extended while reducing airflow friction and lint buildup.

Tapered nozzles accelerate passive freezer vent airflow so moisture freezes into small crystals instead of blocking relief ports with ice.

A curved outlet duct and flexible shaft let air deflection disks follow dashboard contours while keeping airflow adjustment stable and quiet.

Welded fabric strips and edge-to-fin seams create two passages that help fabric tubes resist high air pressure and floodwater displacement.

A plastic multi-part outer diffuser and inner air guide cut ventilator housing cost while improving medium-pressure efficiency and noise.

Fast-curing foamed gaskets and push-lock dimples seal circular duct joints with low tack, cutting air leakage without slowing production.

Temperature and air-quality feedback let a constant-volume AHU run variable airflow, cutting HVAC energy use without coil freezing or overheating.

Auxiliary and pressing rollers stabilize bead rolls, prevent plate bending, and keep mesh-bead duct plates consistent across thickness changes.

Split airflow heats one stream and routes another over the casing to smooth output, keep surfaces cooler, and avoid dust-burning odors.

A foldable blade with tensioned hinges fits through standard register boots, enabling retrofit duct airflow shutoff with less noise.

A notched male-female lock seam and clench tool enable in-line duct seam closure without hammering, reducing noise and metal deformation.

A movable internal partition shifts by air pressure to rebalance warm and cold duct areas, cutting noise in space-limited rail vehicle roofs.

A hollow L-shaped flange uses an embedded sealant strand and deformable fold to improve air-duct tightness and force transfer under pressure.

A zone controller switches ventilation, economizing, and fan operation from occupancy, temperature, and outdoor air conditions to cut HVAC energy use.

Extended condensation channels and a sealing member improve dishwasher vapor condensation, cut indoor humidity, and prevent water leakage.

Divided shrouds create air passages that redirect reintroduced turbulent air, cutting turbofan noise and smoothing airflow in air conditioners.

Curved outlet profiles turn fresh air into a narrow high-momentum surface flow, reducing drafts while keeping ventilation units compact.
