Industrial filters: clean air for working environments

Cartridge filters: compact and high-performance

For the filtration of fine and dry industrial dust, Coral offers compact and ultra-efficient cartridge filters. Thanks to their technical peculiarities, specially designed by our engineers, they offer: alarge filtering surface area in a small space, low pressure drop, automatic cleaning through pneumatic systems (counter-blow or vibration) and easy replacement. These industrial filters are the ideal solution when it is necessary to manage centralized facilities, such as those for welding, laser cutting, machining and industrial painting.

Industrial bag filters: for heavy-duty applications

In more demanding contexts, where significant amounts of slag and dust are generated, our company offers bag filters. Recognizable by their high robustness, they also have the following features:

• Extensive modularity for large-scale installations
• Resistance to high temperatures and aggressive environments
• Long operating life with reduced maintenance requirements

Because of their components, these products can be used in carpentries, cement factories, mills, biomass and waste treatment plants. 

Electrostatic filters: for fumes and aerosols

To perform proper extraction of very fine particles (such as oil fumes, metal mists and fine dust), Coral offers its air filtration systems based on the electrostatic principle. These solutions employ an electric field created by high-voltage electrodes, which ensures more than 90 percent collection of polluting particles and, at the same time, limits the formation of ozone.

The main advantages of using these industrial filters are:

• High efficiency on submicron particles
• Minimum pressure drop
• Regenerable metal structure
• Suitable for continuous and high contamination cycles

Due to their technologically advanced design, these systems are ideally suited for use in metalworking plants, CNC machining centers and precision mechanical industries.

Industrial water filters: for explosive or adhesive dusts

Water filters take advantage of a liquid flow to capture dust and sticky or flammable substances. Specifically, the water comes into direct contact with the pollutant particles, absorbing them and preventing their propagation into the environment. This method ensures deep and safe cleaning, as the harmful component is incorporated directly within the water droplet.

Filters of this type are perfectly suited for activities such as grinding, polishing, and processing aluminum, magnesium, or other combustible powders.

The main advantages are:

• High safety in the presence of sparks or explosive materials
• Consistent efficiency even with sticky particles
• Low maintenance due to liquid-solid separation system

Atex filters: for environments with risk of explosion

For environments with explosive hazards or where flammable materials are used, our company has developed ideal solutions to ensure maximum operational safety for the customer. Compliant with Directive 2014/34/EU, our industrial filters are made with a reinforced explosion-proof structure, capable of containing any damage that may occur during dust handling.

The systems are also equipped with grounding of conductive components, reducing the risk of potential electrical overloads. To handle potential sparks, the filters incorporate anti-spark systems and pressure relief valves. Designed to suit different applications, the filters are fully compatible with ATEX zones 20, 21 and 22. Our ATEX filters are intended for the chemical, food, pharmaceutical, metallurgical and wood industries.

Coalescing filters: elimination of oily mists and aerosols

Coalescing filters are used to separate airborne liquids such as oils and emulsified vapors, providing a viable alternative for air extraction. They work by aggregating droplets until they fall by gravity. Advantages:

• High efficiency in liquid-solid separation
• Protection of downstream equipment (compressors, valves, pumps)
• Ideal for compressed air systems and emulsion mists

Widespread in manufacturing environments with machine tools, lathes and milling machines.

Industrial activated carbon filters: vapor and odor abatement

Activated carbon filters are used foradsorption of gases, volatile organic compounds(VOCs), solvents and odors. Activated carbon traps pollutant molecules due to its porosity. Main advantages:

• Effective neutralization of chemical compounds
• Large active surface area
• Easy replacement of filter cartridges or modules

Ideal in chemical laboratories, paint booths, solvent processes and exhaust air treatment.
