Preventative Maintenance

Preventative maintenance will save down time and money.  One of the advantages of air motors is that they can be safely serviced by a competant mechanical fitter.  If motors are not maintained correctly, the resulting damage will be far more serious than the small amount of time invested to keep them in good condition.

Lubrication
The correct lubrication is important.  Good air motor oil should be resin free, emulsify water and include a rust inhibitor.
Many manufacturers offer lubrication free motors, but the fact is that if lubrication is not used, the maintenance intervals will be higher and the air must be very clean and dry.  Any dirt or water contaminants will severely affect the motor if lubrication is not used.

Regular Maintenance
It is a good idea to strip and inspect the gears, vanes and bearings in line with the manufacturer's recommendations. Depending on the model, Deprag recommend a service after approximately 500 to 2,000 hours of use and then a regular service interval determined. 
A collapsed bearing or dried out grease can result in expensive damage to the gears, as well as the inconvenience of unscheduled machinery down time, so it is important to keep on top of this.

Access to the Motor
Given that regular maintenance is recommended, how easy is it to get the motor out of the machine for servicing?  And how long does it take to service the motors?  Deprag offer a range of motors where the vanes can easily be changed without removing the motor from the machine or pulling the motor apart.
