Yes, it is.
Air pressure does not directly affect gravity. Gravity is a fundamental force that acts uniformly on all objects regardless of air pressure. However, changes in air pressure can influence the density of the air, which may indirectly affect the behavior of objects falling through the atmosphere due to air resistance.
Air does have a weight! And it is because of gravity! Note that this is per definition true because weight is only defined in the presence of gravity. Perhaps you are confused about why the air is up in the atmosphere and not down here on the ground with us? This has to do with air pressure. You see, materials don't like to be compressed, which is what gravity tries to do. Gravity tries to compress the air to the ground, but faces increased air pressure as it does so. Basically what happens is that the air particles repulse each other and thus tend to drive them apart. This force increases if you force the particles to be closer to each other. As gravity tries to pull air down, the air pressure increases which counter balances the pull of gravity. In the end a stable system is formed where the air pressure is highest down near the ground and lowest up in the upper lays of the atmosphere. The air particles up in the atmosphere do feel gravity, but if they would move down they would feel an increased air pressure which pushes them up again!
Gravity causes air pressure by pulling air molecules towards the Earth's surface. The weight of the air above creates pressure on the air below it. The higher you go, the lesser the air pressure due to less weight above pushing down.
Air applies pressure due to the weight of the air molecules above it pressing down. The higher up you go in the atmosphere, the less air there is above you, resulting in lower air pressure. The force of air pressure can be measured and is an important factor in weather systems and air travel.
In simple terms... gravity ! Gravity is holding the air close to the surface of the Earth. The further away you are from the surface - the lower the gravity - and thus the lower the air pressure.
Mass and Earth's gravity
Weight is the force of gravity acting on an object's mass, not air pressure. Air pressure is the force exerted by the atmosphere on objects. Weight depends on the mass of the object and the acceleration due to gravity, while air pressure depends on the density of air and the height above sea level.
Air pressure is caused by the weight of the air above us pressing down on the air below. This pressure is a result of Earth's gravity pulling the air molecules towards the surface. Temperature changes and weather systems can also affect air pressure.

an air compressor Or gravity if you mean atmospheric pressure.

The Earth's gravity pulls the air towards it, creating atmospheric pressure that holds the air in place. This pressure decreases with altitude, which is why the air thins out the higher you go. This balance between gravity and atmospheric pressure is what keeps the air around the planet.
air pressure
Because of gravity
Gravity causes air pressure by pulling air molecules towards the Earth's surface. The weight of the air above creates pressure on the air below it. The higher you go, the lesser the air pressure due to less weight above pushing down.
the result of air mass/air weight is air pressure.
