When clean, hygienic, sterile Dental or medical Compressed air is needed, you Should use the compressor without oil
with filtration system and air drying. The emulsion of water and oil, produced by a
normal lubricated compressor, will notably affect the efficiency of the dentist's rotary instruments;
in addition, given that the air is also used to dry up preparations before Dental cementation, traces of this
emulsion can also prevent proper cementation. This problem becomes more serious when the air
is used in a sterile environment. A sterilizing filter can be inserted only if the air is dry. The use of Dental oil
compressors, combined with filtering systems to trap moisture and emulsified oil, is less safe, more
complicated and will probably end up being more expensive than a Dental oil-less Air compressor.
