Replacing your air dryer is important to protecting your investment down the road. Donaldson experts explain three reasons why.

The efficiency of an air filter actually improves as dust loads up on the surface of the filter, so it gets better as it gets used.

When operating equipment in wet weather conditions, it is common for excess moisture to be drawn into the air intake system.

Pre-cleaners greatly reduce the dirt reaching the air cleaner, resulting in extended filter life. There are many different types of pre-cleaners for different applications; we can help you find the right one.

Many Donaldson air cleaners are designed to be fitted with a safety filter as an optional extra for that added peace of mind.

While new Donaldson air filters provide good engine protection, a Donaldson air filter that has been in service for a period of time works even better than a new one.

Many Donaldson air cleaners are supplied with a small rubber Vacuator™ Valve. This simple device is often overlooked but is critical to the correct operation of the air cleaner.
