Scope of delivery 1 quality filter cassette (no additional locking mechanism). Insert the lid and close it; the vacuum cleaner's suction creates the secure seating of the filter unit. Key benefits Easy installation: no extra clamps or locks required—simply insert and close the lid for immediate, secure operation. Effective dust capture: designed for dry vacuuming of dust classified as L and M (light to medium dust loads). Motor protection and airflow: innovative, airpermeable filter material provides a large surface area for dust collection while maintaining sufficient airflow to protect the vacuum motor and preserve suction power. Better exhaust air quality: the filter reduces particle release into the environment, improving the cleanliness of circulating and exhaust air. Maintenancefriendly: replacing the cassette regularly keeps suction performance and reduces strain on the engine. Function and performance Purpose: designed for dry vacuuming only; collects light to medium dust (dust classes L and M). Material and structure: advanced filter material with porosity and a large dustcollection surface for efficient filtration without severely restricting air intake. Performance effect: balances filtration efficiency and air permeability to maintain suction, prolong motor life, and limit exhaust emissions. Compatibility and use Fits into the filter seat of compatible vacuum cleaners; no additional locking parts required. Verify that the cassette matches your vacuum's filter seat dimensions and design. Practical applications Workshop cleanup: collecting sanding dust, wood shavings, and small debris from carpentry and woodworking tasks. Renovation and construction: vacuuming plaster dust, drywall dust, and other lighttomedium renovation residues. Light industrial or commercial cleaning: handling routine dust removal where L and M class dust is encountered. Maintenance recommendation the filter cassette regularly to maintain full suction power, exhaust filtration, and reduced motor workload. Follow your vacuum manufacturer's guidance for replacement intervals.
