BLEED AIR explained how it effects air conditioning system

Thanks to TVB Media, for a wonderfull video.
Bleed air produced by gas turbine engines is compressed air that is taken from the compressor stage of those engines, which is upstream of the fuel-burning sections. In modern airliner engines, two regulator valves (high stage and low stage) turn on and off automatically and are controlled by at least "...two air supply and cabin pressure controllers (ASCPCs) which open and close appropriate valves. Engine bleed air comes from the high stage or low stage engine compressor section. Low stage air is used during high power setting operation, and high stage air is used during descent and other low power setting operations. Bleed air from that system can be utilized for internal cooling of the engine, cross-starting another engine, engine and airframe anti-icing, cabin pressurization, pneumatic actuators, air-driven motors, pressurizing the hydraulic reservoir, and waste and water storage tanks. Some engine maintenance manuals refer to such systems as "customer bleed air".bBleed air is valuable in an aircraft for two properties: high temperature and high pressure (typical values are 200–250 °C and 275 kPa (40 PSI), for regulated bleed air exiting the engine pylon for use throughout the aircraft)

This sounds like a business opportunity

It can be thought of as roughly the equivalent of taking absolutely all air going into the passenger cabin of your car, and routing it through the intake manifold of the engine first. Who would get in any car knowing that this was the case?

വിമാനത്തിലെ മർദ്ദം നിയന്ത്രിക്കാൻ അല്ലാ, windowകൾക്ക് ഇടയിലുള്ള സ്ഥലത്തെ മർദ്ദം നിയന്ത്രിക്കാൻ ആണ് ആ ശുക്ഷിരം.

Cabin pressurize ചെയ്യാനുള്ള bleed air വരുന്നത് air conditioning ductലൂടെ തന്നെ ആണ്. പുറത്ത് എത്ര low pressure വന്നാലും പുറത്തെ ഗ്ലാസ്‌ പൊട്ടുകയും ഇല്ലാ. ഒരു passenger planeന്റെ maximum altitude 45000 അടി ആണ്. എന്നാൽ അടിയിലുള്ള 10 millibar pressure പോലും windowക്ക് താങ്ങാൻ കഴിയും.

wtf i just saw, in modern technology era can't engineer just put air filter to avoid serious health damage.

A/C MECHANIC FOR SOME TIME STARTED GOOD THEN WHEN TO SHIT I GUESS YOU FOR GOT ABOUT THE ACM, MAIN HEAT EXCHGER, PRIMARY HEAT EXCHANGER, WATER SEPARATOR OH AND THE MIXTURE UNIT AIR DOSENT GO FROM THE ENIGINE INTO THE CABIN WITH PASSING ALL THIS UNITS WHICH CLEAN THE AIR

Now, I understand the COVID-19 where it comes from
