  • VOZDUHOPODGOTOVKA, machining of air for collimating to him of the qualities adequate technological and sanitary-hygienic requests: air filtration from a dust, harmful gas impurity and odors, preheating (or refrigerating), drying (or humidifying), add-on of oxygen, aromatic substances. It is applied in warm-air heating systems, ventilation, an air handling.
  • AIR HEATER, the heat-exchange apparatus for calefaction of air passing through him. It is applied in warm-air heating systems, plenum ventilation, an air handling, in boiler installations TES and industrial enterprises.
  • AIR CURTAIN, the directed air flow given system of aboriginal plenum ventilation, handicapping access in rooms of outside cool air (or hot contaminated air from fabrication systems) through gatepost or technological openings.
  • AIR BUFFER, plenum of air between the grounding of the machine (napr., hovercrafts) and a seating, between mobile and back blocks of mechanisms (napr., the air bearing), in devices (napr., gyros).
