Air Filters

Key Product Features

Backup safety protection barrier

Installed inside the primary air filter SA7912. If the outer main filter is damaged, loose or improperly mounted, this safety element prevents dust, sand and abrasive debris from directly entering engine intake, avoiding turbocharger, cylinder liner and piston severe wear and costly overhaul.

Maintenance anti-contamination function

During primary filter disassembly and replacement, it isolates external dust from flowing into clean air pipeline, effectively prevents secondary pollution in maintenance process.

Stable low airflow resistance design

Optimized pleat layout ensures sufficient air supply for diesel engine, avoids power drop and incomplete combustion. The compact structure maintains low differential pressure during long continuous operation.

Anti-vibration reinforced construction

Metal end cap structure resists continuous vibration of excavators, loaders and stationary equipment, prevents media deformation and air bypass under harsh working sites.

1:1 interchangeable aftermarket spare part

Perfect dimensional match with original air cleaner housing, fully compatible with genuine assembly requirements. Disposable element; cleaning and repeated reuse are prohibited after saturation.

Application Fields

Construction machinery: Excavators, wheel loaders, bulldozers

Mining & quarry: Mobile crushing & screening equipment

Industrial equipment: Large stationary screw air compressors, diesel generator sets

Agricultural heavy machinery: Large tractors and harvesters

Brief Overview

It serves as the last protective barrier of diesel engine intake system to avoid catastrophic engine damage caused by main filter failure. Suitable for high-dust working environments such as construction sites, mines and workshops, it is essential routine maintenance consumable for industrial machinery and air compressors.
