Air/Oil Minimal lubrication is a relatively new technology that has been used successfully to substitute costly Oil Re-circulation and non environmentally-sound Mist Systems.  I

t has provided excellent results both in terms of performance and total system cost. 

It is ideal for use on Bearings, High Speed Bearings, Gears and also in certain circumstances on Guides. It is particularly suited to Spindle Lubrication. 

In the past, excessive oil has been used often only to ensure that the ‘system is working’. This oil generates heat and has to be collected away from the lubrication point. 


High Speed Bearing Lubrication


Industrial Autolube has applied these units in a number of high speed applications with tremendous results, lowering some bearing temperatures by as much as 100F -  38C.  The reduction in oil consumption is huge where a liter can last for up to 2 weeks on some 4 bearing applications!

Dropsa has taken the ‘minimal lubrication’ concept one step further with the VIP4Air that can achieve ultra-low volume oil discharge and at the same time provide electronic monitoring (using a custom designed differential flow sensor integrated into the unit). 

This allows true minimal lubrication by applying micro-amounts of lubricants at more frequent intervals whilst giving positive feedback that oil is correctly being injected and mixed into the air stream. 

The VIP4Air System contains all components necessary to achieve and monitor optimum minimal Air/Oil Lubrication.
