The phrase "active air" is correct and usable in written English.
It can be used in contexts related to environmental science, air quality, or discussions about ventilation and airflow.
Example: "The laboratory requires an active air system to ensure proper ventilation and maintain a safe working environment."
Alternatives: "dynamic air" or "circulating air".
The life history and behavioural traits used for the EG classification were: diel activity period, habitat use when active, habitat use when resting, substrate temperature when active, air temperature when active, relative humidity when active, substrate moisture when active, resting refuge, resting refuge temperature, resting refuge substrate moisture and foraging tactic.
Alongside the traditional pillars of Israel's overall military doctrine, including deterrence and attack capabilities, the new focus is on active air defense, early warning and passive defense, exemplified by bomb-proof secure rooms inside individual homes.
Hence the atmosphere consists of 1/5 of active air (a gas able to combine readily with substances) and 4/5 inactive air (a gas difficult to combine)." When I contemplate this in my schoolgirl handwriting, I see again the apparatus — bell jar, phosphorous, crucible lid, the trough, the water.

A detached single-storey house, without an active air-conditioning system, is refurbished with the installation of macro-encapsulated Bio-PCM™ mats as inner linings of walls and ceilings.
The results show that hybrid approaches to maintaining indoor environmental conditions have the potential to save approximately half of the plant energy consumption compared to common active air-conditioning systems.
Another lay the fault in the lap of an over-active air conditioning unit, tweeting: "The exam hall was too cold for me to write.
In this respect, a pre-normative research is being undertaken at BRRC as a first step towards evaluation of the life time of these photo-active air purifying products.
