The DryAir Filter from DCI is a practical and effective solution to one of dentistry's most persistent problems, contaminated compressed air. Moisture and oil in the air supply can damage handpieces and interfere with dental procedures. The DryAir Filter eliminates oil vapor, water condensate and particulate contamination from the compressed air supply. Wet air is expensive. Moisture in the air supply can break down the lubricants that protect the precision bearings in dental handpieces. Rotating at 350,000 rpm, handpieces don't last long when the lubrication fails. That means costly repairs and expensive down-time. And that's not all. Oil vapor and moisture in the air are inevitably deposited onto the tooth surfaces, interfering with etching and bonding procedures that are so important in dentistry. The DryAir Filter employs a two-step process to condition the compressed air as it enters the dental unit. A replaceable filter element traps oil vapor and particulate contamination, while a unique venturi process eliminates water by converting condensate back into gas, assuring clean, dry air at the point of use.
