High-dust holding capacity cellulose media ensures 99.9% filtration efficiency.
Fully compatible with Donaldson P181191, Fleetguard AF4838, and HiFi SA 14788.
Features corrosion-resistant expanded metal liners and high-density polyurethane seals.
Product Overview: Engineered for Extreme Environments
Engine air intake systems in construction and mining environments face constant exposure to abrasive silica dust. The AYREST A147202 (Primary) and A147203 (Secondary) filter set is engineered to provide a multi-layered defense for high-displacement diesel engines.
The primary filter utilizes deep-pleated media to capture the bulk of airborne contaminants, while the safety (secondary) element protects the engine during primary filter service or in the event of primary seal failure. This combination significantly reduces internal component wear on turbochargers and cylinder liners.

Our manufacturing process focuses on pleat stability and structural integrity, ensuring the filter does not collapse under high vacuum pressure. The radial seal technology provides a leak-proof fit outperforming standard axial gaskets.
Technical FAQ
Q: How do I know when to replace the A147202 air filter?
A: Air filters should be replaced when the indicator reaches the manufacturer's limit (typically 25") or during scheduled maintenance. Visual inspection is not recommended.
Q: What is the function of the A147203 secondary filter?
A: It is designed to protect the engine during primary filter replacement or damage, ensuring no dust enters the intake manifold while the housing is open.
Q: Can I clean these filters with compressed air?
A: Not recommended. Compressed air can create micro-tears in the media. Replacing the element is the only way to guarantee 99.9% efficiency.
Q: Is this filter compatible with Komatsu PC200-6 excavators?
A: Yes, it is a direct replacement for the Komatsu 600-181-1202 series, ensuring identical fitment and performance.
