CUMMINS
4318214 Air Compressor (COMPRESSOR,AIR) is a single-cylinder air brake pump assembly with cross reference number 3104324, professionally matched for Cummins M11, ISM11 and QSM11 series diesel engines1688阿.... As the core air supply component of vehicle braking system, it compresses air continuously to provide stable pressure for truck brake, clutch and auxiliary pneumatic equipment.
This air compressor effectively solves common faults including slow air charging, insufficient brake pressure, abnormal running noise, air leakage and compressor seizure caused by aging cylinder, worn piston and damaged sealing components. It guarantees reliable braking response for heavy-duty vehicles under full-load and long-distance driving conditions.
Thickened Cast Iron Integrated Shell
High-strength cast iron one-piece casting, strong compression and shock resistance, resistant to long-term engine vibration and high-temperature baking, no shell crack or deformation.
Precision Internal Compression Structure
Fine grinding piston and cylinder matching, small internal clearance, high air compression efficiency, fast gas storage speed, effectively avoid brake lag during frequent braking.
Multi-Layer Integrated Sealing System
High temperature resistant oil seal and air seal prevent air leakage and engine oil entering air circuit, reduce maintenance frequency and extend service life.
Excellent Heat Dissipation & Temperature Adaptability
Optimized heat dissipation structure keeps stable performance from -40℃ ~ +135℃, no pressure attenuation under continuous high-load operation.
Anti-Corrosion Internal Channel Treatment
Anti-rust coating inside air passage avoids scale accumulation, keeps smooth air circulation and stable output pressure all year round.
Dual Part Number Universal Matching
Standard mounting interface compatible with 4318214 and cross reference 3104324, perfectly fit Cummins M11 engine installation position, plug-and-play without modification.
Strict Factory Full Performance Test
All compressors pass air pressure test, continuous operation aging test, tightness leakage test and noise detection, stable batch quality for repair shops and logistics fleets bulk procurement.
