Description
Overview:
This Fleece Air Filter is a genuine Stihl spare part designed for selected professional chainsaws, including the MS 201 and MS 201 C. It uses a dense fleece media bonded to a rigid polymer frame to provide reliable filtration while maintaining smooth airflow to the engine. The filter captures fine dust and debris before they reach the intake, helping to protect cylinder, piston, and carburettor components and to keep performance consistent in tough, dusty conditions. Built to Stihl's OEM specification (No. 1145 140 4401), it fits correctly in the airbox and seals firmly to prevent bypass. Ideal for routine maintenance or as a like‐for‐like replacement, it helps your saw start cleanly, idle reliably, and run efficiently throughout the job.
Key Features:
- Genuine Stihl part for assured fit, performance, and durability
- OEM reference: 1145 140 4401 for accurate identification and ordering
- High‐efficiency fleece media captures fine dust and chips to protect the engine
- Rigid, orange polymer frame maintains shape under vibration and repeated use
- Positive sealing edge helps prevent unfiltered air bypass
- Supports stable airflow for reliable starting and steady idle
- Long‐lasting construction suited to regular site work and forestry conditions
- Simple access under the saw's top cover for a quick swap during servicing
- Direct replacement for the original filter on compatible MS 201 series models
- Genuine status reduces risk of poor fit or premature wear seen with copies
Typical Applications:
Routine servicing and replacement on Stihl MS 201 series chainsaws used in arboriculture, forestry, grounds maintenance, landscaping, and construction site work. Suitable for dusty environments such as felling, pruning, snedding, firewood processing, and general property maintenance where clean intake air is essential for consistent engine performance.
