Description
Overview:
This Sponge Pre-Filter is a genuine Makita component for petrol disc cutters, designed to sit ahead of the main air filter to intercept coarse dust and debris. Made from durable foam sponge, it helps protect the engine by reducing particulate ingress and maintaining consistent airflow in demanding, dusty environments. It is engineered for a precise fit on Makita models such as the DPC6200 and DPC6400, ensuring reliable sealing within the air box. Regular replacement or cleaning of the pre-filter supports smoother running, better filtration performance, and longer service intervals. OEM No. 394 173 031. Suitable for professional site use and DIY jobs where concrete, masonry, or asphalt cutting generates heavy airborne dust.
Key Features:
- Genuine Makita part for assured compatibility and fitment
- Foam sponge construction traps larger particles before the main filter
- Helps protect the engine and maintain steady airflow under heavy dust loads
- Supports longer main filter life and consistent performance
- Straightforward to install; no modifications required
- Can be gently cleaned and re-used if in good condition (inspect regularly)
- Stable shape for a positive seal inside the air filter housing
- Suited to harsh site conditions typical of disc cutter use
Typical Applications:
Used on Makita petrol disc cutters working in high-dust environments, including concrete and stone cutting, roadwork, landscaping, and demolition. Ideal for routine servicing to keep the intake system clear, protect engine internals, and help the machine start and run reliably across daily site operations.
