Lubricators are often used to extend the life of expensive pneumatic equipment. The lubricator introduces the correct amount
of lubricating oil into a system, reducing wear and tear. The two basic types of lubricators are oil fog and micro fog.
Oil fog lubricators have a green indicator and have larger oil droplets. These are ideal for a single-point operation allowing lubrication
only horizontally or downhill. Micro-fog lubricators have a red indicator and a fine oil mist for lubrication. They are are recommended for
most applications and can lubricate points even uphill.
