Air Filter Safety Radialseal

Why choose Donaldson Safety Filters?

Safety filters have 2 functions: to act as a backup to the primary filter and to protect the engine during primary filter servicing

• serve as a backup filter in case of primary filter damage or improper installation.
• Prevent contaminants from entering the clean side of the air intake system during primary filter servicing.
• Designed to plug rapidly if contamination finds it way past the primary filter, alerting operators about an issue.
• We recommend that you replace safety filters with every third primary filter change unless there has been a failure of the primary filter.

What is a safety filter?

Many Donaldson air cleaners contain two filters. The larger one is the outer or primary filter. The role of the primary filter is to remove contaminant in the air coming from the intake system as it passes through the air cleaner.

Often a smaller filter is either inside, or sometimes after, the larger primary filter. We often refer to this smaller filter as a secondary or inner filter. We prefer to call this smaller filter the safety filter as this better describes its role.

The safety filter usually uses a different type of media from the primary filter. The media is more open for lower restriction and is less efficient, meaning it won’t plug on exhaust soot and oil fumes but will still stop small, engine damaging, dirt and dust particles. Depending on which air cleaner the safety filter is designed for, they can have a pleated construction similar to the primary filter, or can be a ‘slim line’ design often found in smaller air cleaners where space is limited.

With less contaminant holding capacity, the safety filter will plug rapidly on engine damaging particles that find their way past damaged primary filters. This alerts the operator that both filters need to be changed when the restriction level reaches the designated service point. If the safety filter is not changed at this time, the maximum restriction level will be reached very quickly
