Condition: used, Year of construction: 2016, functionality: fully functional, machine/vehicle number: 16501575, volume flow: 4,800 m³/h, input voltage: 380 V, power: 2.5 kW (3.40 HP), Equipment: type plate available, The resulting dirt particles, emulsion and oil mist, as well as smoke, are captured directly at the source and passed through the individual filtration stages. The separated liquid collects at the bottom of the unit and can be returned to the machining center via the siphon. In the first filtration stage, larger particles are retained by an aluminum pre-filter to protect the downstream high-performance fleece filters. The second filtration stage removes the majority of fine emulsion and oil mist. This stage consists of an aluminum frame equipped with a G4 filter mat and an F5 filter mat according to DIN 24185 / EN 779. The filter mats must be replaced depending on the degree of contamination. The third filtration stage consists of a large-area HEPA filter of class H13. A consistently high filtration efficiency of 99.95% at a particle size from 0.3μ DOP is ensured here. Type testing in accordance with DIN EN 1822-1 H13 allows the filtered air to be returned to the workspace. Lhodpfx Ajyz Sn Njqvog

Condition: new, Year of construction: 2026, The air filter for the ZP7500 sweeper is a key component of the filtration system, responsible for effectively capturing dust, fine particles, and small debris generated during operation. Its use significantly reduces airborne dust, resulting in improved operator comfort and a cleaner working environment. During sweeping, contaminants are not only collected by the brushes but also drawn into the machine along with air. The air filter ensures these particles are effectively trapped, preventing fine dust from being released back into the surroundings. In practice, this means more efficient and “dust-free” cleaning—especially important in warehouses, production halls, and enclosed spaces. Lodpfx Aqsyvp Tfovohg A large filtration surface area and properly structured filter material allow for the effective capture of even very fine particles. Modern sweepers often use panel filters, which offer high performance and ease of use—frequently equipped with shaking or cleaning systems that help maintain consistent efficiency. The filter also serves a protective function for the machine’s components—it prevents contaminants from entering the suction system and other working parts, reducing the risk of failure and extending the machine’s lifespan. An additional advantage is easy access and quick replacement, allowing the machine to be kept in optimal condition without unnecessary downtime. Regular inspection and cleaning of the filter are key to maintaining maximum sweeper performance. Key benefits: effective reduction of dust during operation improved air quality in the working environment high efficiency in filtering fine particles protection of machine components from contamination extended lifespan of the sweeper easy maintenance and quick replacement The air filter is an essential component for ZP7500 sweeper users who expect maximum cleaning efficiency while maintaining high comfort and safety—especially in dust-intensive environments.
