Dust, fume and mist extraction
Protect your operators and the environment from harmful emissions & improve indoor air quality in the workspace

dust, fume and mist extraction solutions for industrial applications

Almost all industrial manufacturing processes generate emissions in form of dust, fume, smoke or mist. These emissions need to be captured from the process before they are released into the ambient air and spread to the workspace. Using a well-balanced extraction system provides the needed protection for employees, combined with an efficient filtration equipment that will yield low energy consumption and supports preservation of the environment.

At Camfil, we realise each industry has to deal with its own unique set of challenges and concerns when it comes down to protect operators, processes and the environment from harmful emissions. Industrial manufacturers have to address issues such as workplace exposure limits, combustion and explosion, cross-contamination or local legislation around health, safety and environment.

Filter elements for industrial extraction systems

Filter elements are the integral component of any dust collector or mist separator and affect the separation efficiency as well as the energy efficiency of the entire extraction system. Camfil´s high-quality filter elements are available with different filter media, each providing special properties to ensure best filtration performance on various applications and emissions as well as an optimised filter life.

Also available: retrofit filters in different length, diameters and with different flanges to perfectly fit into the most common industrial dry dust and fume extraction systems on the market.

Consultation is a matter of trust

We would be glad to get to know you personally in an initial consultation or at an on-site appointment to learn more about your specific manufacturing processes, the emissions to be extracted and the installation environment in your facility. Based on this information, we will provide you with a non-binding tailor-made offer for one of our extraction systems that meets the requirements of the respective application. Ask us!

filtration technologies Camfil offers

Dry filtration solutions are used in different industries such as metalworking, food and beverage or pharma and perform on a wide variety of challenging industrial applications, handling harmful, combustible dust and fumes including fine, fibrous, abrasive or heavy dust loads.

The so called dust and fume collectors are cleanable filtration solutions which are mostly used when the concentration of the air pollution in a facility is at or above 0.05 mg/m³ and a stationary filter leads to short filter life.

Dry dust and fume collectors utilise filter elements to separate airborne particles from the airstream. The filters get cleaned by a pulse of compressed air and the particles are discharged to a collection bin.

Camfil´s dust and fume extraction systems provide a near-limitless variety of configurations and airflow capabilities which is why the units are easily adaptable to specific work environments and spatial conditions. For example, the dust collectors can be tailored with optional explosion protection or containment systems in order to provide the necessary required safety.

Wet filtration is mostly used on industrial processes which release dust and other particles that are difficult or impossible to handle with dry filtration solutions like explosive, combustible, sticky or fibrous dusts.

While dry dust and fume collectors are equipped with filter elements to collect particles from the airflow, wet filtration systems use water as filter media. The functional principle of the so called wet scrubbers make use of the principle of mass inertia, through which the particle-laden process exhaust air is integrated into fine water droplets, thereby increasing the mass of the particles and thus safely separated. Afterwards the cleaned air can be returned back into the production or out of the facility. The collected waste water and the filtered solid substances have to be divided and disposed of correctly via appropriate waste streams. 

Wet scrubbers can be classified according to design features or method of liquid feed. The selection of the scrubber type is application-specific and depends on the required air volume, the pollutants to be separated, the particle size and the dust load in the process exhaust air.

Camfil offers Venturi and Vortex wet scrubbers. Whereas Venturi scrubbers are the best solution to handle fine particles with high dust loads, Vortex scrubbers are used to remove coarse particles with light to medium dust loads from exhaust gas streams.

Depending on the application and the processed material, machine tools use different liquids as emulsion, oil or MQL for cooling the tools within the machine, to clean the workpiece during the processing procedure or for chip disposal. As those metalworking fluids are injected with high pressure together with the speed of the tools, the fluids vaporise and create coolant mist inside the working area of the machines. 

Before opening the doors for changing tools or workpieces, the coolant mist has to be extracted from the working area of the machine. This is mandatory to protect the workers occupational health, to eliminate safety risks and to control the indoor air quality.

Machining mist collectors can be used as centralised or decentralised extraction solutions or for direct machine tool integration. Due to the latest filter technologies, Camfil┬┤s industrial mist collectors combine the advantages of filtering separators and coalescence separators and provide best filtration efficiencies together with low energy consumption and long filter lifetimes.
