Dental air compressor is vital to our dental practice. We should know more about different dental compressors. When looking for compressed air for your dental practice it is important that you get the best possible air quality and that your dental compressor provide you with the air you need to operate your practice. As a dentist you focus is on the patient and you just want know that you buy the best solution for your dental business. And there are many considerations for selecting dental compressors.
The air that is produced by the compressor is used directly in human mouths. They will inhale the air and swallow any contaminations that is within the compressed air. Of course, the compressor and the compressed air must meet the highest possible standards!
In the old days, dentist had no other choice than to buy a oil-lubricated compressor and use filters in the compressed air line to filter out any oil in liquid or vapor form. But, with filters you can never be 100% sure. Filters will get old and require replacement in time, before they deteriorate. Nowadays, a whole range of oil-free compressors is available on the market. Oil-free compressors have the big advantage that they are 100% oil-free, so there is zero chance of oil in the compressed air system.
To properly size a compressor, you need to know your air consumption and the capacity of the compressor. Consumption is usually determined by how many operatories are in use at a time. Capacity is the compressor output in cubic feet per minute (cfm), and can usually be found in product literature.
The key point is that two compressors may put out the same cfm, but the one with the lower duty cycle cannot run as much without reducing its service life. Duty cycle varies widely among compressors, so ask your supplier about it.
Compressed air quality depends on the inlet air and what the compressor adds to it. Both oil-less and lubricated compressors are used in dentistry. Both require particulate filters to remove any airborne dirt and dust. With a lubricated compressor, the system must also include reliable coalescing filters to ensure patient safety.
Dental compressors have “heads,” with each one housing one or more pistons. Some models employ a single head, while others use a multihead design. A common misunderstanding is that a machine with multiple heads has built-in backup. When a multihead compressor has a malfunctioning pump, it may not be able to continue running on another head.
Manufacturers make choices in design and materials to meet target price points, so quality varies widely. Following are some points to consider when comparing compressors.
Heads should be made of quality materials and designed to remove heat. Finned cylinders, large cooling fans, and filters are important features. Components should be designed to be serviced, not replaced. For example, antifriction coatings like Teflon are widely used to reduce piston wear.
Though it is often hard to quantify up front, your experience has probably shown that good quality dental equipment pays for itself. In the long run, quality compressors last longer, with less frequent repair and lower service costs.
