Cartridge Dust Extractors

Self-cleaning cartridge filter Extractor

Cartridge Dust Extractors by Dena AFS. The great advantage of the self-cleaning cartridge filter consists in the compact overall dimensions in relation to the large filtering surface available. The extensive customization and the different types of filtering materials make it possible to cover almost all the problems that can be solved with this type of filters. The self-cleaning cartridge filter was created as a valid alternative to traditional sleeve filters. As such it allows, for the same dimensions, a filtering surface that is several times greater.

Uses of the self-cleaning cartridge filter

One of the many advantages of the cartridge filter consists in the compact overall dimensions. In particular in relation to the large filtering surface available. The wide modularity and the different types of filtering materials make it possible to solve almost all the problems that can be addressed with this type of filter. Cartridge dust extractors collectors were designed as an alternative to traditional bag filters. This is because they allow, for the same size, a 20 times greater filtering surface.

MODEL GIC-ATEX/GIM ATEX BLAST PANEL

DESCRIPTION & SPECIFICATIONS:

The GI-ATEX model bag filter is an autonomous dust filtration system. Equipped with automatic cleaning with compressed air, specifically for the filtration and relative separation of medium, fine and impalpable dust. The automatic cleaning system using compressed air jets allows the pressure drops to be kept almost constant. The filter is protected with a venting system designed and installed based on the characteristics of the dust and the place in which the machine is installed. This type of filter allows, in combination with special compartmentation systems, to avoid the explosion of the filter and pipes.

Principle of operation

In the GI-ATEX bag filter the dusty air enters directly into the dust collection hopper. Thanks to the combined effect of the reduction of air speed and flow distribution, a part of the dust precipitates directly into the hopper, the remaining part deposits on the external wall of the filter elements.

The very permeable material of the filter bags allows gas to pass through. However not dust, which gives the filter its main filter layer. It is essential to carry out correct removal to guarantee optimal filtration efficiency and low pressure drops. This is balance is achieved through the DENA PULS-JET system. A jet of compressed air, accumulated in a special tank, is injected cyclically inside the sleeves. Thus creating a violent counter current shaking wave capable of detaching and precipitating the particles deposited on the external wall of the sleeves.

Construction details

The bag filter is made of very thick galvanized sheet metal and is complete with support legs, inspection doors and dust collection hopper.

MODEL GI C-C

DESCRIPTION & SPECIFICATIONS:

The dusty air is introduced into the lower part of the hopper through the mouth connected to the panel.

The coarser dust contained in the sucked air already undergoes an initial reduction and falls into the collection hopper due to the notable reduction in speed.

Passing the hopper, the dust passes through the filter cartridges, passing from the outside to the inside, thus depositing the impurities in the collection hopper. During work, the filter is always kept in perfect efficiency through a cyclical counter-current cleaning system.

A jet of compressed air, accumulated in a special tank, is quickly injected inside the cartridges, creating a violent countercurrent shaking wave capable of detaching and precipitating the particles deposited on the outside of the cartridges. The double clapet valve will discharge the dust cyclically.

Construction details of the GIC cartridge dust collector filters

The GIC cartridge dust collector is made entirely of thick galvanized sheet metal, suitably worked and treated, to ensure its durability over time.

MODEL DEPRO

DESCRIPTION & SPECIFICATIONS:

The Depro Dena cartridge filter for air purification is equipped with automatic cleaning with compressed air, specifically for the filtration and relative separation of medium, fine and impalpable dust. The automatic cleaning system allows you to keep the pressure drops almost constant and therefore the suction constant.

Operating principle of cartridge filters

The dusty air is introduced below the filter cartridges through the mouth connected to the hopper. The dust contained in the sucked air precipitates into the collection container due to the notable reduction in speed, and is subsequently conveyed to the filter cartridges passing from the outside to the inside, thus depositing the impurities in the collection hopper.

During work, the filter is always kept in perfect efficiency through a cyclical counter-current cleaning system. A jet of compressed air, accumulated in a special tank, is suddenly injected inside the cartridges, creating a violent counter current shaking wave capable of detaching and precipitating the particles deposited on the outside of the cartridges.

MODEL CFO-TC

DESCRIPTION & SPECIFICATIONS:

Industrial processing operations produce fumes that must be extracted in order to enjoy a healthy working environment that complies with regulations.

There are as many system options as there are industrial operations. It is important to design and create tailor-made solutions for the extraction of different fumes; in the metalworking sector, for example, it is necessary to capture the fumes as close as possible to the polluting source, as required by community legislation. Whatever the industrial sector in which you operate, Dena Aspirazioni is able to create tailor-made fume extraction systems. All Dena branded systems are characterized by ease of installation and reduced maintenance.

Fume extraction and filtering unit

The fume extraction systems, however different they may be, are all made up of a filtering unit composed as follows:

filter module – made of aluminum profiles, with double-walled panels;
prefilter – composed of pleated fabric, essential for blocking particles with larger grain sizes;
pocket filter – to filter the smallest particles;
electrical panel – for controlling the engine, made according to EU standards.

Welding fume extraction

One of the most delicate industrial processes in which fume extraction is necessary is welding. Obviously, welding exposes operators to various risk factors.

The resulting smoke is a mixture of different chemical components that varies according to the material being welded. As such some of them are particularly harmful and must be extracted with care to preserve the health of the welders from respiratory diseases and more.

The extraction of welding fumes usually occurs through mobile purifiers connected to centralized extraction systems. They are perfect systems for workshops where the work is spread across multiple points distant from each other, but above all with few operators. If there are many operators, the advice is to install a centralized fume extraction system with multiple arms or extractor hoods .
