Technical Product Description
The Critical Function of the PA2806 Air Filter
An air filter is a primary engine defense component designed to intercept airborne contaminants-such as silica dust, soot, and carbon-before they reach the combustion chamber. The PA2805 and PA2806 series are high-capacity radial seal filters specifically engineered for large-displacement industrial engines. By maintaining a low initial restriction and high filtration efficiency, the PA2806 ensures the optimal air-to-fuel ratio required for isochronous operation in standby power systems.
Solving Intake System Pain Points
- Reducing Abrasive Wear: The PA2806 utilizes deep-pleat technology to trap micro-dust particles down to the micron level, preventing "cylinder scuffing" and piston ring failure.
- Eliminating Seal Leaks: We use high-elasticity polyurethane (PU) end caps that maintain an airtight seal throughout the entire maintenance cycle, preventing "dirty air" bypass.
- Overcoming OEM Availability Issues: Sourcing branded filters like Caterpillar 3I0021 or Sdmo 330560300 can involve long lead times. AYREST provides a technical equivalent that matches original specifications.
Why Choose AYREST as your Filter Supplier?
Material Science: We utilize specialized synthetic-blend media that resists moisture-induced pleat collapse, common in humid Southeast Asian and coastal environments.
TCO Optimization: Our filters offer an equivalent service life to OEM parts at a significant cost reduction, lowering the Total Cost of Ownership (TCO) for fleet managers.
Reliable Consistency: With 15 years of experience, we employ strict OEM Benchmarking to ensure every batch meets Donaldson and Fleetguard performance standards.

Frequently Asked Questions
Q: How do I know when to replace my PA2806 air filter?
A: Replacement should occur when the intake restriction indicator reaches the red zone or during scheduled maintenance every 500-1,000 hours.
Q: What is the benefit of the radial seal design in the PA2806?
A: It utilizes a flexible urethane end cap for a high-compression airtight seal, providing a larger surface area and reducing air bypass risks.
Q: Can the PA2806 replace the Donaldson B120376 exactly?
A: Yes. AYREST PA2806 is engineered to the exact technical dimensions (267mm D1, 304mm H1) ensuring 100% interchangeability.
Q: Does moisture affect the performance of this air filter?
A: Our filters use resin-impregnated fibers which enhance water resistance, preventing pleat collapse in humid or rainy environments.
