Compatible Stihl Trimmer Models

This 25-piece air filter set fits Stihl grass trimmers and brush cutters including the FC55, FS38, FS45, FS46, FS55 and HL45 models. It replaces the original equipment manufacturer part numbered 4140 124 2800. The pack supplies enough filters for multiple routine service intervals on two-stroke petrol engines.

Sustained Engine Protection

Under continuous cutting load, the filter media traps dust and debris before they reach the carburettor, maintaining consistent airflow to the two-stroke engine. Clean intake air prevents lean-running conditions that cause overheating and power loss during extended use. Regular replacement keeps compression stable across long working sessions.

Maintenance Schedule Limits

A clogged filter restricts the air volume required for correct fuel mixture, so the practical limit is the interval between inspections. Heavy dust or dry grass environments shorten that interval significantly. The 25-unit quantity allows operators to swap filters on site without delaying work when the element becomes saturated.

Questions about this item

Will the 25-piece pack of air filters keep the Stihl FS55 running cleanly during all-day landscaping work?

Each filter is built for 2-stroke petrol engines such as the FS55, trapping dust so the carburettor stays clear through long cutting sessions.

Do I need a specific Stihl trimmer model for these 25 filters to fit, or will they work on any brand?

They are direct replacements for Stihl models FC55, FS38, FS45, FS46, FS55 and HL45, matching OEM reference 4140 124 2800.

Can I use these filters on an older Stihl FS38 that I have kept for backup jobs?

Yes, the FS38 is listed among the compatible models, so the filters will seal correctly on that older unit.
