Maintenance of dental equipment is imperative for a successful dental practice. Maintaining the equipment used in dentistry not only helps to avoid unexpected problems, but it can also aid in enhancing the equipment's life. Whether the equipment is utilized on a daily, weekly, or monthly basis, it all requires maintenance. Hereby we are sharing our 3rd Blog on Maintenance Series, i.e. “Maintenance of Compressors”. In case you missed our 1st two blogs, “Maintenance of Dental Handpieces” & “Maintenance of Dental Chair”, you can refer to our website.

Dental Practices depend solely on the dental air compressors for the functioning of most of the basic dental equipment, starting from a dental chair to a dental handpiece. In such a case investing again and again in a new dental air compressor can be inappropriate for a dental professional.

The performance of the dental procedures is considered excellent when the air quality provided by the dental compressor is hygienic and pure. As dental air compressors must meet stringent hygiene standards, their use is carefully monitored. This is to avoid exposing the patients to various pathogens while performing dental procedures that could lead to infections in a healthy individual.

How Does the Dental Air Compressor Work?

Dental Air Compressor is equipped with a Storage tank, piston and air filters, etc. The air enters through the air inlet and gets compressed that converts to pressurized air. The pressurized air is now filtered. This is accomplished with the help of an integrated filtration mechanism that is built into the dental air compressor. The filtration mechanism eliminates all types of contaminants, producing clean, dry, and hygienic air. This hygienic pressurized air is driven through a hole in the tank for storage for further use of much air-driven dental equipment in the clinic.

Problems Faced by Dental Professional When Compressor breaks down:

As dental professionals solely depend upon dental compressors that provide pressurized air for the dental equipment to function. When it breaks down, he may face several issues in the dental clinic, i.e.

  • Dental Chair won’t work due to which basic dental procedure will be hampered
  • Dental handpieces won’t work
  • Dental Chair won’t work due to which basic dental procedure will be hampered
  • Dental handpieces won’t work
  • 3-Way syringe won’t work
  • Delivery unit stops working
  • Scalers won’t function

Mistakes that reduce the life of the Dental compressor:

Mostly the maintenance of the dental compressor is done by the assistant in the dental clinic. There are a few very few known mistakes, done by the assistant, that reduces the life of the dental compressor.

  • Not draining the stored air on a daily basis
  • Not getting it serviced at least once in a year
  • Monthly checking of air filters and air leakage by the service engineer
  • Not switching off the Compressor while leaving the clinic
  • Filters not getting cleaned timely

Tips to Maintain the Dental Air Compressor: 

  • Drain Stored Air Daily:

The drain air in the compressor may induce the growth of many pathogenic organisms of remained for a longer duration. The Tank drain valve should be opened and the stored air should be released on the daily basis.

  • Moisture check in the Tank:

Every 90 days, the moisture in the storage tank should be checked. The presence of moisture can lead to the growth of many compressor-bred microorganisms.

  • The dryer/ Air Filter Check:

The dryer or Air Moisture filter help in providing dry air by eliminating the moisture from the compressed air. Hence the dryer should be replaced once a year for smooth functioning of the air filter/dryer.

  • Proper Ventilation Check:

The dental air compressor, as it takes the environmental air, there is a risk in placing the dental air compressor near the drainage system or the suction system. Hence, it is essential to check for the proper ventilation of the dental air compressor.

  • Check for the Electricity Connections:

Before leaving the dental clinic, the main power switch of the dental compressor needs to be turned off for increasing the efficiency of the dental compressor.

  • Annual Servicing of the Dental Air Compressor:

Annually the dental compressor should be checked by the service engineer and the issues like leakage, holes, air quality, air pressure, the flow rate should be checked. The filters/ dryers should be changed.


Every dentist’s top goal is keeping patients free from all types of pathogenic organisms, and dentists are legally mandated to service and test air compressors for increasing air quality once a year. The time it takes to pressurize the tank determines the compressor's efficiency. Unicorn Denmart’s dental air compressors are built to provide years of unchallenging, efficient, and continuous operation for an uninterrupted dental practice, while certain Dental spare parts do need to be serviced on a regular basis. By following the maintenance Tips properly and setting up a servicing schedule with our skilled and certified service engineers will help you to avoid unplanned problems.
