Filtration Performance & Engine Protection
The Donaldson P551402 boasts 99% filtration efficiency at 21 microns, tested to ISO 16889 standards, making it ideal for protecting SDMO GEM 600 generators and compatible engines. Its cellulose media effectively traps dirt, metal shavings, and sediment, preventing premature wear to critical engine components.
It features a bypass valve with dual setting ranges: 2.2 bar (32 psi) for low range and 2.7 bar (39 psi) for high range. This valve activates during filter clogging, ensuring uninterrupted oil flow and preventing engine damage from oil starvation. Additionally, its full-flow design ensures all engine oil passes through the filter for maximum protection.
Consequently, the P551402 minimizes costly engine repairs and unplanned downtime—critical for generator operations relying on continuous power. Its consistent performance builds trust among maintenance teams, while its ISO 16889 compliance guarantees reliability for industrial and commercial applications.
