The maintenance sprays support the daily use of your instruments, guaranteeing you impeccable maintenance, optimal operation, and an extended service life.

Supported handpieces include turbines, contra angles, and handpieces. Compatible with a 6-pin, 4-hole, or 5-hole connector. 1-year warranty on unit; however, if unit is purchased at the same time as Bien-Air electric contra angle attachments, the warranty of the attachment will be extended to 2 years.
