Description
Overview:
This air filter is a flat, white, non-woven fleece element designed to keep dust and debris out of small two-stroke engines. It measures 61 x 56 x 8 mm and is an aftermarket replacement for Stihl outdoor power tools such as the HS 45 hedge trimmer and FS 55 brushcutter. The dense filter media maintains good airflow while trapping fine particles to protect the carburettor and cylinder. Used as part of routine servicing, it helps engines start reliably, idle smoothly, and run at the correct mixture. It replaces Stihl reference 4140 124 2800 where specified and fits neatly in the original airbox without modification. Suitable for domestic users, trades, and grounds teams who need consistent performance from their equipment.
Key Features:
- Precision size: 61 x 56 x 8 mm for a snug, leak-free fit in the OEM airbox
- Aftermarket replacement compatible with Stihl 4140 124 2800 (41401242800)
- Durable non-woven fleece media for effective particle capture with stable airflow
- Helps protect carburettor and engine internals from dust ingress
- Supports easier starting, smoother running, and more consistent tuning
- Simple, tool-free fitting on most listed machines
- Lightweight, rigid enough to handle regular servicing and replacement cycles
- Cost-effective maintenance part for regular filter changes
Typical Applications:
Used during routine servicing of line trimmers, brushcutters, hedge trimmers, and Kombi engines to restore airflow and protect engine components. Common in garden care, landscaping, grounds maintenance, facilities management, and hire fleets where reliable running and reduced wear are important.
