P119374 AIR FILTER, SAFETY

Safety filters have two 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 its way past the 
primary filter, alerting operators about an issue.

• Recommend that safety filters are replaced with every third primary 
filter change unless there has been a failure of the primary filter.
