Factsheets - Know How for Compressed Air

Factsheets serve to give a compressed but significant information on various topics in the field of "compressed air" in a short time. Furthermore the knowledge of products will be extended and know-how of compressor stations will be given. This is a database of compressed air basics for your daily practice and will be extended on a regulary basis.

Oil-free compressed air

In this section you will find the factsheets on the topic of oil-free compressed air.

Production of oil-free compressed air

To produce oil-free compressed air, operators have essentially three options: oil-free compression, compressed air purification by means of activated carbon or treatment in a catalytic converter.

Production of oil-free compressed air with activated carbon and refrigeration drying

For the production of compressed air of ISO 8573 quality class 1, most operators use activated-carbon adsorbers that remove oil molecules from the compressed air by means of adsorption.

Maintenance

In this section you will find the fact sheets on the subject of maintenance and repair.

Preventive maintenance

Even high-quality compressed air system components are exposed to some wear. Preventive maintenance aimed at reducing the risk of failure or malfunction includes the timely replacement of wear and maintenance parts. Depending on the actual operation and the prevalent operating conditions, such parts should be replaced at least every 12 months.

Optimisation

In this section you will find the fact sheets on the subject of optimizing the efficiency and cost savings.

Compresssed air filters - The cost of pressure drop

Compressed air filters improve the quality of the compressed air by removing contaminants. As these tend to deposit on the filter material, the pressure drop increases gradually over time. To ensure that there is sufficient pressure available at the consumers, the compressor must compensate this pressure drop, which results in higher energy costs.

Optimising system pressure

An operating pressure that is too high by as little as 1 bar can already lead to a huge increase in operating costs.
