Product catalog summary
Overview
This document outlines the technical specifications and usage guidelines for post-filters used in industrial air filtration systems, focusing on oil mist and dust filtration. These filters enhance air quality by capturing pollutants through various mechanisms.

Specifications
Two main types of post-filters are detailed: Hepa cartridge post-filters and activated carbon post-filters. Hepa filters come in F9 (95% efficiency) and H13 (99.95% efficiency) models, suitable for fine mists and smoke. Activated carbon filters are designed to adsorb odors and gases, featuring a surface area exceeding 950 m2/g.

Applications
These filters are recommended for machining processes that generate oil mists and dust, such as cast iron processing and pressure die-casting. They can be paired with centrifugal air filters to purify air contaminated by dust, vapors, and smoke.

Maintenance
Regular maintenance is crucial, with Hepa filters requiring replacement approximately every 1000 hours. The replacement frequency for activated carbon filters varies based on pollutant characteristics and the working environment.

Technical Characteristics
The document provides technical data, including maximum air flow rates, filtration efficiency, total filtering surface area, and net weight for various models. Clipper models, for instance, have air flow capacities from 600 m3/h to 3200 m3/h, with filtering surfaces between 5.5 m2 and 15.5 m2.

Installation and Usage
Filters can be installed horizontally or vertically. Specific instructions for replacing active carbons in cylindrical containers are provided, highlighting the importance of correct procedures to maintain efficiency.

Conclusion
Post-filters are vital in industrial air filtration systems, designed to improve air quality by capturing a wide range of pollutants. Proper selection, installation, and maintenance are essential for optimal performance.
Specifications and Functionality
The document describes a filtration system with filters and a large expansion chamber for pollutant separation through fluid expansion and deceleration. It is suitable for grinding, shaving removal machines, and washing machines, effectively separating sprays, water droplets, emulsions, and oil.

Filter Options
Two filter options are available: FM, a washable metal filter for rough filtration, and FSM, a combination of synthetic and metal for finer filtration. An attachment is included for discharging separated fluids.

Installation and Configuration
The system can be installed vertically or horizontally, near the aspirator, machine tool, or on existing tubing. Its adaptable configuration is beneficial in centralized systems to reduce pollutant accumulation in tubes. The two versions differ in fluid flow direction.

Dimensions and Models
Dimensions for different models, including TWIN DARWIN, are provided, with specifications for both metallic and synthetic filters.

Italiano English Deutsch CLIPPER 100% INCENERIBILE burnable BRENNBAR F9 > 95% H13 > 99,95% Post-filtro a cartuccia Idoneità Hepa cartridge post-filter Uses Kartuschen-Nachfilter Anwendung Le particelle inquinanti vengono trattenute da questo post-filtro in fibre sintetiche grazie ai seguenti principi filtranti: diffusione, inerzia e intercettazione diretta. E’ indicato in tutte quelle lavorazioni che producono una particolare tipologia di micro-nebbie di olio intero o emulsionato miste a polveri di materiali conduttori (es. lavorazioni su ghisa, pressofusione ecc..). Il nostro post-filtro è disponibile in vari modelli con due diversi livelli di efficienza: F9 (95%) e H13 (99,95%). Quest’ultimo è in grado di trattenere anche fumi. Può essere usato in combinazione con tutte e tre le tipologie di aspiratori (turbina, mono e doppia centrifuga). This hepa after-filter retains polluting particles thanks to the following main filtration effects: diffusion inertia and direct interception. It is recommended for those machining processes producing fine mists from neat or soluble oil mixed with dusts (especially of conducting materials: e.g. cast iron processes, pressure die-casting etc.). Our after-filter is available in various models with two different levels of efficiency: F9 (95%) and H13 (99,95%). The H13 is also able to retain smokes. The after-filter can be used in combination with the three kinds of air filters (turbine single and double centrifuge). Dieser Endfilter ist geeignet für alle Bearbeitungen, bei denen ein spezieller Mikronebel aus gemischten, emulgierenden oder reinen Ölen und Staub entsteht, der auf leitende Materialien zurückzu-führen ist (z. B. Gusseisen-, Pressguss-Bearbeitungen). Unser Endfilter ist in verschiedenen Modellen mit zwei unterschiedlichen Leistungsniveaus erhältlich: F9 (95%) und H13 (99,95%). Mit dem H13 Filter kann auch Rauch filtriert werden. Endfilter Clipper kann mit den drei Technologien (Turbine, Eizelzentrifuge, Doppeltezentrifuge) montiert werden.
