Before sealing, which is prefrably done by welding, air is extracted from the sack.

Air is displaced by these tread grooves while rolling, which also cause air vibrations.

Expiration is the phase of ventilation in which air is expelled from the lungs.

Expiration is the phase of respiration during which air is expelled from the lungs.

Upon application of external pressure to the arch cell, air is expelled from said air cell through said conduit member.

Our unique AirFree vent is designed to help your baby swallow less air as they drink, by drawing air away from the nipple.

Air is flushed out of the sleeve (26) as it is filled, particularly as a result of the expansion of the resin foam produced by the polymerisation of the pressurised liquid material injected through an opening (40) in the sleeve.

The procedure is carried out in the same way as when booking the bottom: the cylinders are initially cleaned, the air is driven off, dimensions are taken and the material is glued.

To deflate the bag, the compressed air is bled away from the bag.

Is it air or is it water which is thus driven out?

The piston (17) is expelled by an electromagnetic repulsion with the elasticity of the air compression.

Any air remaining in the water softener is purged to the drain.
