More Dent BR-414B-M 4-Hole Air Micromotor

The More Dent BR-414B-M air micromotor is a low-speed metal rotary motor equipped with a standard 4-hole pneumatic connection. Designed for restorative procedures and prosthetic adjustments in the dental practice, this instrument connects directly to the hose of your dental unit to drive contre-angles and straight handpieces equipped with external irrigation lines. The instrument operates under a working air pressure adjusted between 0.22 and 0.30 MPa, delivering a continuous rotational speed exceeding 18,000 rpm. Its internal metal drive mechanism maintains a measured acoustic noise level below 65 dB during operational trimming, drilling, or polishing phases at the dental chair. External irrigation routing provides direct supply of cooling liquid via dedicated external tubing to the head of the attached contre-angle or handpiece. This pneumatic micromotor remains compatible with all standard low-speed rotary instruments manufactured according to standard universal coupling dimensions.
