Technical air

Air - a mixture of gases, mainly consisting of nitrogen and oxygen. Compressed air - air is under pressure above atmospheric pressure. With the invention of the compressor came the era of industrial compressed air.

The main characteristic is its compressed air pressure.

Absolute pressure is measured from the zero, the excess pressure is the total pressure minus atmospheric pressure. For the case of pressure measurement in technical atmospheres overpressure denoted as "atm", and absolute - as "ata".

Standard ISO 8573.1 provides air size classification of the solid particles (D), the maximum content of (C) and the dew point (T) and the content of oils (Oil).

Because liquids and gases pollute the atmosphere low in their use in the manufacture, they does not require sealing of pneumatic systems. This allows you to install fairly simple and inexpensive device. Pneumatic systems in power per unit mass in an intermediate position between electric and hydraulic systems and have several advantages. In particular, their function insensitive to radiation and extreme temperatures. Service maintenance is quite simple and can be provided by low-skilled staff.

Application

Pneumatic tools:

Paintball, airsoft, airguns. Screwdrivers, wrenches, pneumatic drills.

Mechanical engineering:

Vehicles with compressed air, pneumatic conveying plants - the movement of bulk cargo using air flow, air brakes, running diesel engines as an alternative to starting using starter, cleaning of electronics components that can not be cleaned with water. Cooling by vortex effect.

Energy storage.

Diving operations:

Vertical forcing off the water - the application of the caissons and diving bells. Refilling cylinders with air.

Building:
Horizontal pneumatic forcing off the water used in the construction of tunnels and drifts.
