2. Duct (flow) - Wikipedia

   en.wikipedia.org/wiki/Duct_(flow)

   Some flexible duct markets prefer to avoid using flexible duct on the return air portions of HVAC systems, however flexible duct can tolerate moderate negative pressures. The UL181 test requires a negative pressure of 200 Pa. To use flexible ducting in a system, make sure to pull the duct tight so you get the full internal diameter.

4. Duct (industrial exhaust) - Wikipedia

   en.wikipedia.org/wiki/Duct_(industrial_exhaust)

   Industrial exhaust ducts are pipe systems that connect hoods to industrial chimneys through other components of exhaust systems like fans, collectors, etc. Ducts are low-pressure pneumatic conveyors to convey dust, particles, shavings, fumes, or chemical hazardous components from air in the vicinity to a shop floor or any other specific locations like tanks, sanding machines, or laboratory hoods.

5. Air handler - Wikipedia

   A RTU viewed from inside with supply diffusers and return vent (center right) Air filtration is almost always present in order to provide clean dust-free air to the building occupants. It may be via simple low-MERV pleated media, HEPA, electrostatic, or a combination of techniques. Gas-phase and ultraviolet air treatments may be employed as well.

6. Register (air and heating) - Wikipedia

   en.wikipedia.org/wiki/Register_(air_and_heating)

   A register is a grille with moving parts, capable of being opened and closed and the air flow directed, which is part of a building's heating, ventilation, and air conditioning (HVAC) system. The placement and size of registers is critical to HVAC efficiency. Register dampers are also important, and can serve a safety function.

7. Ventilation (architecture) - Wikipedia

   en.wikipedia.org/wiki/Ventilation_(architecture)

   A local exhaust system is composed of five basic parts: A hood that captures the contaminant at its source; Ducts for transporting the air; An air-cleaning device that removes/minimizes the contaminant; A fan that moves the air through the system; An exhaust stack through which the contaminated air is discharged [35]
