Air Cleaner Filter Vacuator Valve for Donaldson
The Air Cleaner Filter Vacuator Valve P158914 is a replacement dust unloader cap designed for Donaldson air cleaner systems. This vacuator valve automatically ejects dust and water from the pre-cleaner bowl without allowing unfiltered air into the intake. It is a direct replacement for the OEM P158914 part number.
Overview
This vacuator valve is a flexible rubber cap that attaches to the bottom of an air cleaner pre-cleaner assembly. It operates by opening under the force of falling dust particles to discharge them, then sealing shut to maintain intake vacuum. This air cleaner filter vacuator valve is essential for keeping the main filter element clean and maximizing service intervals.

- Self-cleaning duckbill design requires no maintenance.
- Directly replaces Donaldson part number P158914.

On-The-Job Use

Good To Know
Q: How do I know when to replace the vacuator valve? A: Replace it when the rubber becomes stiff, cracked, or fails to close completely, which may show as dust buildup around the pre-cleaner outlet. Regular inspection during air filter service is recommended.
Q: Can this valve be used on any air cleaner? A: It is specifically designed for Donaldson systems that accept the P158914 style vacuator valve. Verify the mounting neck diameter and retention method to ensure a correct fit.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
