Flowing HVAC air inflates a surrounding jacket to form a static insulating layer, raising duct R-value without extra insulation material.

Locator tabs and hanging brackets let one installer align, slide, and secure an undercabinet ventilation hood without filler strips.

A hand-rotatable discharge element adjusts airflow rate, pattern, and direction to improve comfort while reducing air-conditioning energy use.

A removable bottom purge nozzle matches different FOUP port shapes while maintaining airtight sealing, alignment, and easy maintenance.

Rotating locking clips and a gasket seal duct openings without tape gaps, loose parts, or repeated re-sealing during maintenance.

Support brackets and front tabs or feet let one installer align and secure an undercabinet ventilation hood without paper templates or filler strips.

Interchangeable pliable duct sections with disconnectable joints enable custom diameter, length, and adjustable airflow discharge.

Nested telescopic duct sections cut transport volume and impact risk while making aircraft ventilation easier to handle and install.

Movable screens cover unused supply openings so aircraft passenger service modules can be repositioned quickly without adhesive seals or air leaks.

Inclined sealing lips and a convex profile end keep wall element joints tight despite wider tolerances, without added support parts.

A flexible duct fits into a removable unit recess to vent ozone and discharge products without increasing image forming module height.

A motorized retractable air hose uses torque sensing and heated storage to prevent kinking, ease ground handling, and maintain aircraft cooling airflow.

A dual mineral wool and reflective laminate layer raises HVAC transition box R value to 8+ while keeping total insulation under 2 inches.

Stabilizing sections spaced along a flexible duct prevent folding during bends, maintaining cross-section, reducing turbulence, and improving flow reliability.

A Teflon guide in a frame channel removes threaded fasteners from the air path, preserving airtight HVAC sealing and low leakage.

An integrated foldable flow straightener in the measuring funnel cuts swirl-related errors while avoiding separate assembly and bulky rigid parts.

Distinct sign sections on indoor unit outlets and flaps help users identify each remotely controlled flap without adding multiple flap shapes.

Preassembled fire-rated duct shafts with integral subducts cut on-site fabrication, reduce trade coordination, and speed HVAC installation.

A bulged air outlet and matching airflow guide extend conditioned-air throw while blocking recirculation into the inlet.

A self-sealing transition module cuts ERV shipping size and installation labor by replacing manual sealing and simplifying unit mounting.

A convex guide wall and switchable concave valve hide the air outlet while preserving directional airflow using the Coanda effect.

Polypropylene sandwich panels, bonded joints, and flange fastening cut duct weight while maintaining gas-tight, pressure-tight corrosion resistance.

Support brackets with locator tabs and ramped hangers align and hold an undercabinet hood, enabling faster one-person installation.
