Selection notes for field service
Use this guide as a purchasing checklist, not as a substitute for sample confirmation. Where machines share the same platform, confirm the exact engine, hydraulic circuit, fuel system or compressor stage before placing a bulk order.
- Confirm the OEM number or cross-reference from the old filter, maintenance book or equipment plate.
- Compare height, outside diameter, inside diameter, thread or gasket position before approval.
- Match the media requirement to dust load, fuel cleanliness, oil mist separation or hydraulic cleanliness.
- Request clear product photos, sample packing and carton marks before repeating orders.
- For OEM projects, confirm logo file, label language, carton size and annual forecast.
