Compressor Applications

 

Compressed air, commonly called Industry's Fourth Utility supplies power for many different manufacturing operations. It supplies motive force, and is preferred to electricity because it is safer and more convenient.

For the production line Gardner Denver offers pneumatic tools convenient for industrial production because they have a low weight-to-power ratio.

Spray finishing equipment

Air is used to vaporize paint so it can be applied to components and products.

Air operated tools

Air tools are preferred to electric tools as they are light and easy to handle,

Air operated lifting equipment

Air hoists can be used for a multitude of lifting operations. They are small and compact.

Cooling and heating

Compressed air is used in a vortex tube to create high volumes of cool air for industrial cooling processes. Vortex tubes can also be reverse flowed to produce high temperature air used in heating processes.

Cleaning

Compressed air is used for cleaning processes in manufacturing facilities.

Environmental

As the cleanest form of energy around it makes sense that compressed air is a major consideration in environmental products and projects. Oil free and oil lubricated compressors are used in a variety of applications from air conditioning systems, to the development of re-usable energy forms and power generation plants. Compressed air is versatile reliable and safe, it can be used directly in the process such as sewage treatment plants or air separation, or it can be used as a motive force in an environmentally friendly process.

 

Air conditioning

Compressed air is used for control systems to operate the opening and closing of control valves.

Wind generation

Compressed air is used in the manufacturing process of wind generators. It is also used as a source of energy that can be generated by wind farms.

Sewage plant

Compressed air is used to control sewage flow, and air oxidation of sewage tanks.

Water purification and oxidization

Compressed air is released into water to stop stagnation.

Landfill sites

Compressed air is released into the ground to push out toxic gases.

Air separation

Compressed air is filtered via a membrane to generate clean gases.

Artificial snow making

Compressed air is used to atomize water through a series of orifices and projected into the air by a powerful fan. The atomized water falls as snow.

Portable Compressors

Portable Compressors areused to operate mobile shot blasting units and for mobile, point of use paint spraying.

Blower and Vacuum Applications

 

Pneumatic conveying: pressure mode

A blower brings air sucked from the atmosphere to the required pressure level. As a result of the excess pressure, air flows into the conveyance conduit. A rotary air lock directs the goods being transported into the conveyance conduit. Air and goods flow through the conveyance conduit into the separator, which separates the goods from the air. The air flows through the clean air conduit back to the outside. The goods being transported leave the separator and are then stored, conveyed or processed.

The movement of the goods depends on the means of conveyance and the construction of the conveyance installation. Due to the low pressure difference available to suction conveyance systems, pneumatic suction conveyance installations have a larger conduit diameter than pressure conveyance systems, yet the volume of goods transported remains the same.

Pneumatic conveying: suction mode

The suctioned air creates a mixture of air and transported goods in the conveyance conduit. The conveyance apparatus extracts the granulate from the sieve filter. Operating data: Operating pressure is between -200 mbar and -500 mbar. The air velocity in the conveyance conduits determines the principle of operation.

Depending on the goods being transported, this speed is about 20 m/s to 23 m/s. The vacuum pump must be designed so that the air velocity in the conveyance conduits does not drop below the minimum rate, even at the machine located the farthest away, and that no plugs build up. This requires a higher air velocity at the pump High conveyance velocities, however, lead to increased wear of the conduits and to abrasion of the goods. Therefore, selecting the optimal air velocity or blower is of utmost importance.

Optimal air volumes can be achieved in modern conveyance installations with frequency controlled vacuum pumps.
