A good source for compressor recommendations is your local Patterson equipment specialist or service technician.
The key factor — often overlooked by doctors — is number of users, according to Wittenberg. “It’s better to meet your user needs or be a little bit over than to have less and risk problems later,” he said. A compressor system that is the right size for your practice is more efficient and will last longer.
Oil-less vs. lubricated
There are two types of dental air compressor: oil-less and oil-lubricated. If maintenance is not routine at your office, an oil-less compressor may be the better choice.
Air from an improperly maintained lubricated compressor can become more contaminated over time. Oil vapor acts much like bad cholesterol in the body: components will become clogged or damaged. This oil vapor can negatively impact health, dental instruments and restorations. In addition to demanding regular maintenance, oil compressors require scheduled oil changes. Since they expel oil constantly, oil levels must be checked regularly.
Oil-less compressors also require routine maintenance, including replacing filters. Wittenberg advocates oil-less models. “These will be the industry standard,” he said. “The new mechanics are better and last longer, and there’s very little maintenance.”
Wittenberg said some oil-less compressors may be slightly noisier, but generally these units are housed in a soundproof room or in the basement where noise is not a factor. Soundproof compressor covers are also available. Several of the newer oil-less designs are actually quieter than oil-lubricated counterparts.
Price vs. value
The next important issue is price. Reviewing the benefits and the recommended size compressor for your practice will help you determine which is the best value.
Lubricated compressors cost less. Although in the long run, the cost of oil and wear on handpiece turbines, if the compressor is not properly maintained, may make oil-less compressors more cost-effective. Remember to ask if the compressor you’re thinking about buying comes complete and ready to install.
