Pressurized air that will enter the pneumatic system has to be processed to eliminate dust particles, moisture.
A full, pressurized air treatment units can be seen in the following scheme:
Pressurized air treatment to meet the requirements required for adequate equipment, including:
Air filter (air filter), serves as an air filter tool taken from outside air which still contains a lot of dirt. The filter serves to separate particles that are carried away such as dust, residual oil, etc.
Air compressor serves to suck atmospheric air and then compress it to a storage tube up to a certain pressure. Before use, there must be a pressure air treatment system for cleaning and drying before use.
Pressurized air that comes out through the filter still contains moisture. Moisture in pressurized air can cause corrosion of all channels, connections, valves, unprotected equipment so it must be dried by separating water through a water separator tube.
Pneumatic system components require lubrication to prevent wear and can reduce heat arising from friction. Therefore compressed air must contain lubricating fog obtained from the lubricating tube on the regulator.
Pressurized air regulator:
Air that has met the requirements, will then be distributed according to needs. To regulate the size of the incoming air, air taps are needed on the regulator, so that air is supplied in accordance with its work requirements.
Pressurized air treatment units have piping installation networks that have been designed so that water can be separated from the air. Water has a higher period (Rho) so it tends to be at the bottom. To trap it, the installation of the pipe is given a slope, the water will flow naturally to the water reservoir tube, then discarded. While dry air is taken from the top of the plant to have a low water content.
