Pneumatic lubricator GM.4

Reliable and robust Easily refillable Modern, light and robust, the Montabert line oiler features a large capacity that works in any position and can be easily refilled. Oil flow supply is instantaneous and constant and easily regulated. Owing to its original design, it does not drain when stopped. When used with a medium size rock drill, the pressure loss is so low that it cannot be measured by normal means.
