A dental air compressor pressurizes atmospheric air for use in procedures. Standard compressors are not suitable for this purpose because they may not meet health and safety standards. Dental firms can choose from an array of models designed for small, medium, and large practices with a variety of features.
The operation of an air system requires more than just an ability to turn the right switches. One of the most important aspects of the whole operation is the maintenance of the compressor and various other components, because this ensures long life and efficiency for an air system. Unfortunately, compressed air maintenance mistakes are often made by operators who’ve only familiarized themselves with the basic workings of the equipment.
Common mistakes in compressed air maintenance include failure to assess energy costs and the impacts of contamination and condensation. These mistakes alone can lead to inefficiency and parts failure that can result in losses in the tens of thousands over the course of a given year. Further compressed air maintenance mistakes include a lack of attention to secondary components and a failure to properly train all members on staff of the finer nuances of compressor operation.
Compressed air should always be oil free. Nonetheless, oil serves as a necessary evil in the process of air compression. As such, the process has its share of potential consequences. As the air is compressed, oil is used for the purposes of cooling, lubrication, and sealing. Unfortunately, up to half of the degraded oil can pass through the system in vaporized form, especially when temperatures are high. The system itself can also draw unburned hydrocarbons, which condense once cooled. When acidic oil vapors mesh with moisture in the compressed air, corrosive buildup forms along the air receivers and valve cylinders.
It must be noted that dental oilless air compressors are not contaminant-resistant compressors. In other words, the inlet valve of an oil-free compressor cannot magically filter out airborne contaminants from ambient air. Just as with an oil-lubricated system, an oil-free compressor needs filtration to keep water, dirt, unburned hydrocarbons, and other impurities from the compression process.
Some manufacturers offer refurbished units which have been carefully serviced before sale. These units are similar to those that are new, but have a lower price because they’ve been gently used. It may also be possible to rent a unit, which can help defray the startup costs for a dental practice. The equipment needed to start offering services to patients can be substantial, making it expensive to start a new business.
