A large variety of vacuum pumps and compressors are used in the wood industry. The pumps are also used in carpentry as central vacuum systems to improve efficiency and minimize costs associated to connections and special bases that are no longer needed.

The centralized vacuum system
Centralized vacuum systems are used in hospitals and ambulatory surgical centres to extract fluids produced during surgery. A separator is installed in the surgery room to separate fine particles from the largest. If the surgery room is too small, the vacuum system may also be alternatively installed remotely.
In recent decades the food and beverage industry has undergone generalized changesfrom small to medium and large businesses. The resultingindustrialization of food processing has created many applications using vacuum pumps and compressors.
1. Bottles filling - machines in beer factories
2. Chocolate production
Machine manufacturing is closely linked to production and processing of plastics. Plastic manufacturers develop and produce optimized plastics for a range of purposes. From these, the processor makes high-quality products that are used in almost all industrial sectors, from automotive and telecommunications to food processing industry. Machine...
Circular and flat knitting machines
In the manufacturing of technical textile, textile dirt is produced. This dirt is collected by means of a vacuum tank with a side channel blowers.

Wastewater treatment / Oxygenation of activated sludge tanks; to reduce space requirements and costs of the wastewater treatment plant, an increasing number of active sludge tanks is being created. The introduction of oxygen is extremely important for the purification of wastewater. Blowers to provide the required pressure for maximum performance o...
Vacuum is mostly employed in the metallurgical field, however there are specific applications where air pressure is also necessary. Pumps / dry compressors are mostly used.
4. Oxidation prevention
In the production of bricks, tiles, porcelain and technical ceramics, a leading quality brand consists in a product free from air pockets. When produced, ceramics containing those pockets can be destroyed in the oven and, in extreme cases, may even cause the destruction of the whole lot. This quality defect often appears afterwards in bricks, durin...
Solvent recovery: waste water contaminated with solvents should be treated for environmental reasons. The simplest method consists in vacuum distillation, here the lower part evaporates at the boiling point and then is condensed. The wastewater is then transported elsewhere to be used afterwards.
Food packaging: air and its oxygen content can have harmful effects on the quality and durability of fresh foods. Therefore many processes need vacuum. The classic vacuum application in this field is vacuum packaging. Before sealing, a vacuum pump removes the air from the package. Vacuum pumps are used in many packaging machines for industrial use,...
The aeronautic industry uses machines requiring a good performance combined with good resistance and a precise final result. In GriÃ±o Rotamik we work to fulfil these requirements and we have wide variety of products for many of the different applications required by this sector.
Compounds consist of two or more components which are glued together and pressed by vacuum system into an aluminium bag.

5. Degassing and debubbling
1. Drying of electronic components: electronic components, such as printed circuit boards, are dried and cleaned with compressed air.
2. Electronic components, such as transistors, capacitors, etc. are inserted on the plates. The handling and positioning is performed by means of vacuum pipettes.
For this process, we have...
