FAQ - Frequently Asked Questions
A1: The outer filter (Primary) stops 99% of large dust particles, while the inner filter (Safety) protects the engine in case the primary filter is damaged or during a filter change. Replacing them as a set ensures 100% airtight protection and prevents fatal dust from entering the combustion chamber.
A2: For typical construction sites or mining zones with high dust levels, we highly recommend inspecting the filter every 100–250 operating hours and replacing it immediately if the restriction indicator light turns on, or if the filter paper becomes excessively clogged with soot.
A3: Yes! We are a professional industrial filtration manufacturer supporting global B2B trade. We offer bulk packaging (individual boxes or pallet packing), support private label OEM services, and provide reliable global sea/air freight. Contact our sales team today for a factory-direct quote!
