Diesel Generator Set Spare Parts Filters

ZTA Power Generator Filter Series

Our filter series covers the three essential filtration needs of diesel generator sets. Each filter is manufactured to meet or exceed OEM specifications, using high-quality filter media, precision-threaded housings, and corrosion-resistant surface treatments.

Diesel Filter (Fuel Filter)

The ZTA Power Diesel Filter is engineered to remove contaminants from diesel fuel before it reaches the high-pressure injection system. It uses a multi-layer filter media with water-separation capability to protect sensitive fuel injectors and pumps.

Air Filter

The ZTA Power Air Filter prevents harmful dust, sand, and particulate matter from entering the engine's combustion chamber. It uses a high-capacity pleated media design that maximizes filtration surface area while maintaining optimal airflow.

Lube Oil Filter

The ZTA Power Lube Oil Filter removes metal wear particles, soot, and oxidation products from engine lubricating oil, protecting bearings, turbochargers, and cylinder walls from abrasive damage.

Why Filter Quality Matters for Your Generator

Using low-quality or incorrect generator filters can cause fuel injection system damage, excessive engine wear, reduced power output, and catastrophic engine failure. A single batch of contaminated fuel passing through a substandard diesel filter can destroy a high-pressure fuel pump, resulting in repair costs exceeding $5,000 USD for a 500kW generator set. Investing in OEM-grade filters from a trusted manufacturer is the most cost-effective insurance for generator longevity.

Risks of Substandard Filters

ZTA Power Quality Commitment

Every ZTA Power filter undergoes a rigorous quality control process:

1. Raw material inspection — Filter media density, thickness, and permeability tested upon arrival

2. In-process quality checks — Pleat count, adhesive bond strength, and dimensional accuracy verified during production

3. Finished product testing — Each batch is sample-tested on our in-house generator test bench for flow rate, pressure drop, and filtration efficiency

4. Batch traceability — Every filter carries a laser-etched batch number for full production traceability

Our filters are manufactured in compliance with ISO 9001:2015 quality management standards and meet the technical requirements of Cummins and Perkins engine specifications.

Generator Filter Replacement Schedule

The standard replacement schedule for diesel generator filters follows industry maintenance guidelines: lube oil filters should be replaced every 250-500 operating hours or at every oil change, diesel fuel filters every 500-1,000 hours, and air filters every 500-1,000 hours depending on environmental dust levels. For standby and emergency generators compliant with NFPA 110 standards, all filters must be replaced annually regardless of operating hours to ensure readiness during power outages.

Standard Maintenance Schedule

Important: Operating environment significantly affects filter life. In dusty environments (construction sites, mines, deserts), air filter replacement may be required every 250 hours. In high-humidity environments, fuel filter water draining should be performed daily.
