With the Milwaukee ptfe flat filter, you maintain consistent suction power and optimal airflow during demanding sanding, drywall, and grinding jobs. The durable ptfe membrane delivers a 99.9% filtration efficiency, reliably capturing fine dust and preventing airborne particles from escaping through the vacuum exhaust. Its non-stick coating reduces clogging, while the washable design allows you to rinse it easily with water to extend its service life. Flexible integrated gaskets create an airtight seal inside your Milwaukee as 30 lac or as 30 mac dust extractor, ensuring a clean and safe working environment on every jobsite.
