2. Vacuum chamber - Wikipedia

   en.wikipedia.org/wiki/Vacuum_chamber

   A large vacuum chamber. A small vacuum chamber for studio or lab use in de-airing materials such as mold rubbers and resins. Vacuum chamber for testing leaks in packaging. A vacuum chamber is a rigid enclosure from which air and other gases are removed by a vacuum pump. This results in a low-pressure environment within the chamber, commonly ...

   en.wikipedia.org/wiki/Cryopump

   Cryopumps are commonly cooled by compressed helium, though they may also use dry ice, liquid nitrogen, or stand-alone versions may include a built-in cryocooler.Baffles are often attached to the cold head to expand the surface area available for condensation, but these also increase the radiative heat uptake of the cryopump.

4. Physical vapor deposition - Wikipedia

   en.wikipedia.org/wiki/Physical_vapor_deposition

   Physical vapor deposition (PVD), sometimes called physical vapor transport (PVT), describes a variety of vacuum deposition methods which can be used to produce thin films and coatings on substrates including metals, ceramics, glass, and polymers. PVD is characterized by a process in which the material transitions from a condensed phase to a ...

5. Vacuum sewer - Wikipedia

   The main components of a vacuum sewer system are a collection chambers and vacuum valve parts, sewers, a central vacuum station and monitoring and control components. Some vacuum systems have vacuum toilets which are connected directly to a vacuum line, which requires less water for flushing (less than a quarter of a liter per flush). [4]

6. Vacuum flange - Wikipedia

   en.wikipedia.org/wiki/Vacuum_flange

   A vacuum flange is a flange at the end of a tube used to connect vacuum chambers, tubing and vacuum pumps to each other. Vacuum flanges are used for scientific and industrial applications to allow various pieces of equipment to interact via physical connections and for vacuum maintenance, monitoring, and manipulation from outside a vacuum's chamber.
