The air coming from the air container (13) takes the place of the removed air.

The air discharged from the upstream air electrode (4a) is supplied to the downstream air electrode (4b) after passing through the humid air passage (6).

Seoul-bound Korean Air flight evacuated at Tokyo's Haneda airport

1 - air removed outside; 2 - air sucked from outside; 3 - extractor fan; 4 - heater; 5 - heated air

Air discharged from the oil following the path A exists through an air outlet (22).

Following a calculation, the quantity of evacuated air is obtained.

The air that enters cracks in a home’s envelope to replace air that is exhausted is called “makeup air.

An air discharging port (41), an air blowing port (44) and a conversion valve (3) are provided downstream of the discharged air filter (2).

An air filtration system is described for removing oil and grease entrained in air extracted from the region above a cooker.

The exhaust air is generally wasted as it is diffused back to the atmosphere.

Mechanical ventilation with heating recovery from exhaust air

In the first stage of the process the outgoing air is passed through at least one condenser so that the additives or pollutants contained in the air can be condensed out.

A proportional regulation is established between the supply air and the exhaust air.

Air discharged to the outside through respective filters (40) is filtered.

Furthermore, the exhausted air facilitates removal of swarf from the worked face.
