Donaldson Filtration X002277 Informer Air Cleaner Restriction Gauge Kit

The Donaldson X002277 Informer is a precision air cleaner restriction gauge designed to continuously monitor air filter performance and maximize filter service life. This reliable gauge provides accurate readings measured in inches of water vacuum, eliminating the guesswork from filter maintenance and preventing premature filter replacement.

Key Features:

• Visual indicator with clear window that turns red when maximum restriction is reached
• Provides precise readings showing remaining filter life
• Measures restriction in inches of water vacuum (25" limit)
• Top-mounted reset button for easy operation
• 1/8-27 NPT thread for universal compatibility
• Highly resistant to vibration, breakage, weather, corrosion, dust, and dirt
• Ensures dependable, reliable filter restriction readings

This restriction gauge helps reduce maintenance costs by enabling filter replacement based on actual restriction readings rather than visual inspection or arbitrary schedules. Visual inspection alone is inadequate for determining filter service life—filters that appear dirty may still contain substantial remaining capacity. The Donaldson Informer ensures you get maximum utilization from each air filter while maintaining optimal engine performance and protection.
