MS290 Air Filter: The "High-elastic Dust-proof Foam Core" of Heavy-duty Chainsaws

The MS290 Air Filter is the "high-elastic dust-proof foam core" of heavy-duty chainsaws like Stihl MS290, designed for high-load logging scenarios. Its filter core uses 30PPI high-elastic polyurethane foam, with 30% better pore toughness—it fits tightly with the intake cavity to intercept wood chips and dust, while maintaining shape during high-frequency chainsaw vibration to avoid "air leakage short-circuit".

The reinforced ABS housing is modified for drop resistance, with an impact strength of 15J, withstanding bumps and drops in outdoor operations; the metal fasteners have 20% deeper engagement, no loosening due to vibration after installation. Compared to traditional paper air filters, its washable feature extends a single filter’s service life to 800 hours, reducing comprehensive costs by 65%.

Whether for high-intensity logging in forestry or heavy pruning in gardening, the MS290 Air Filter provides long-term clean intake protection for heavy-duty chainsaws with "high-elastic sealing + impact resistance + washable" performance, being the core component of high-load outdoor operations.
