For Sinotruk T7H/A7 Shacman X3000/X5000 SITRAK G7 Truck Parts Fusheng Air Compressor Air Filter 2116040158 Air Filter
| Attribute | Specification |
|---|---|
| Formal Name | Air Intake Filter Element for Screw-Type Air Compressors |
| Function | Filters particulate contaminants from ambient air entering compressor systems |
| System Application | Pneumatic systems ONLY (air brake reservoirs, air suspension, pneumatic tools) – NOT engine intake |
| Core Components | - Filter media: Multi-layer cellulose/synthetic blend (450 g/m² basis weight) - End caps: Polyurethane ( Shore A 85) - Support core: Perforated steel mesh (0.8mm thickness) - Gasket: NBR rubber (Shore A 70) |
| Operating Principle | Airflow → Pre-filtration stage → Depth filtration → Clean air delivery to compressor |
| Critical Feature | Water-repellent coating (prevents media saturation in high-humidity environments) |
 |  |
| Parameter | Value | Tolerance |
|---|---|---|
| Outer Diameter | 152.4 mm (6.00 in) | ±0.2 mm |
| Inner Diameter | 88.9 mm (3.50 in) | ±0.15 mm |
| Height | 177.8 mm (7.00 in) | ±0.3 mm |
| Filtration Efficiency | 99.5% @ 5μm | - |
| Dust Holding Capacity | 1,200 g | - |
| Pressure Drop (New) | 1.8 kPa @ 2.8 m³/min | ±0.2 kPa |
| Max Operating Temp | -40°C to +80°C | - |
| Service Life Indicator | Pressure drop > 5.0 kPa | - |
✅ Key Clarifications:
NOT FOR ENGINE INTAKE: This is a pneumatic system filter (for air brake reservoirs), NOT for diesel engine air intake (common marketplace error).
2116040158 ≠ Engine Air Filter: Engine air filters have different dimensions (typically larger) and filtration requirements (ISO 5011 Class 1 vs. Class 3 for pneumatic).
TRUCK APPLICATION CONTEXT: Used in air brake compressor systems (not engine), primarily on:
Heavy trucks with air brakes (e.g., Sinotruk T7H, Shacman X5000)
Construction equipment with pneumatic systems
| Compressor Model | Valid Applications | Exclusion Warning |
|---|---|---|
| Fusheng SA Series | ✔️ SA+04, SA+06, SA+08, SA+11 (all kW variants) ✔️ Requires 152.4mm OD filter | ❌ Not for GA Series (different mounting) |
| Truck Air Systems | ✔️ Sinotruk T7H/A7 (WABCO brake system) ✔️ Shacman X5000 (Knorr-Bremse system) | ❌ Not for hydraulic brake systems |
| Other Models | ✔️ FAW J7 air brake systems ✔️ Shacman X3000 (2018+ models) | ❌ NOT for engine intake (e.g., ISG12 engine) |
| System Type | Compatibility | Critical Note |
|---|---|---|
| Air Brake Reservoir | ✔️ Full compatibility | Filters air BEFORE entering reservoir (prevents moisture accumulation) |
| Air Suspension | ✔️ Compatible | Must meet ISO 8573-1 Class 2 for particle count |
| Pneumatic Tools | ✔️ Compatible | Ensures clean air for sensitive tool mechanisms |
| Engine Intake | ❌ Incompatible | Incorrect filtration efficiency (causes engine damage) |
| Feature | Technical Rationale |
|---|---|
| Water Repellency | Hydrophobic coating prevents media saturation (critical for truck air brake systems in wet conditions) |
| Dust Holding Capacity | 1,200g capacity ensures 6,000–8,000 km service intervals in normal conditions |
| Pressure Stability | Maintains <5.0 kPa pressure drop until end-of-life (vs. 3.5 kPa for inferior units) |
| Thermal Stability | Operates at -40°C to +80°C without media degradation (meets ISO 16750 requirements) |
| Failure Mode | Media saturation → Increased pressure drop → Moisture ingress → Brake system corrosion (82% of field failures – Fusheng FR-2022-067) |
