The Streamliner DC automatic single point lubricator offers maintenance professionals the ability to keep equipment properly lubricated. The key to the high degree of reliability with the Streamliner DC is the innovative, fully-adjustable gas generating power source. The power source generates gas that creates a consistent pressure on a piston which gradually and continuously dispenses the lubricant contained in the chamber. Delivery time is easily set with a simple twist of an allen key on top of the unit. The dispensing time of the Streamliner DC is variable between one and twelve months allowing complete control over the amount of lubricant being applied. Comes pre-filled with Mobilith SHC 100. Environmentally friendly.
