used to create negative pressure in a room when clearing air for asbestos removal and other harmful particulates
Mathematically speaking, 0 is neither positive nor negative. In machine language in computers, 0 is considered as "positive" since the negative flag is not set.
I don't think velocity can be a negative number... Use positive.
because we breathe in the oxygen which is flowing around this earth and when we breathe in this oxygen around us ,we also breathe in air pollution which is not good for all things living on this planet.
is that both grasslands and clearing forests for farming are both negative and effective to the environment because the forests are what pollutes the air for us to breath with oxygen and that gives us nitrogen that we both need
Negative * positive = negative Positive * positive = positive Negative * negative = positive
Air pollution is negative

A ride in the air, usually on machine.
The chiller is machine that evaporates liquids through an absorption process. This machine also cooled air and equipement. In others words this machine is and Air-Water Cooling System.
The use of a machine to move air. In medical terms, a machine to aid a person in breathing by moving air into and out of their lungs.
car
yes. its called an air purifier..
negative
Yes, because PV=nRt From this equation it becomes apparent that air pressure, V, can be negative. Since negative temperatures can exist, such as -30C (remember you have to use Celsius and not Fahrenheit). Thus we have negative numbers for air pressure.
The induced air flotation machine was invented by William Fagergren in the 1930's in the Salt Lake Valley of Utah. Induced air means that the rotor for the froth flotation machine draws in atmospheric air, rather than having an air compressor or blower providing "forced air".
The used to have SF6 in the air gap.
