The Perma Star Vario is an electromechanical single point lubricator which delivers optimal lubrication to machine elements such as bearings and chains.  The perma Star Vario single point lubricator provides a reliable alternative to manual lubrication and has many advantages when compared to gas type lubricators.
The key differences between the perma Star Vario and gas type lubricators are listed below: 

• Grease dispensing from the Star Vario is controlled via a battery powered mechanical drive system which delivers measured volumes of grease at precise intervals.
• The rate of grease dispensing is independent of ambient temperature and can be varied by means of simple-to-apply settings.  Refer to Table 1 below.
• The higher pressure output from the Star Vario facilitates flexibility for remote mounting options.
