CARTRIDGE FILTERS
for industrial filtration
CARTRIDGE FILTERS
Cartridge filters represent the optimal solution for industrial applications characterised by moderate concentrations of dust and fine particles.
With proper design and maintenance, industrial cartridge filters ensure high and consistent performance over time, contributing to improved production efficiency and enhanced workplace air quality.
Each system is engineered following a thorough technical assessment to guarantee maximum performance, full operator safety, and compliance with applicable regulations. Ease of maintenance and seamless integration with existing installations make cartridge air filtration systems the ideal choice for a clean, safe, and efficient working environment.
CARTRIDGE FILTER OPERATION
Contaminated air enters the filter through a settling chamber or tangential inlet and, through decantation or cyclonic effect, is pre-separated from the heavier particles.
These particles fall directly into the hopper below, where they are collected and discharged through a screw conveyor or rotary valve, ensuring a continuous and controlled discharge process.
The remaining airflow, containing finer particles, then passes through the filter cartridges from the outside to the inside, allowing effective filtration and the release of purified air through the filter outlet.
To maintain cartridge efficiency, the filter is equipped with an automatic reverse pulse cleaning system: short pulses of compressed air are injected inside the cartridges, facilitating the removal of deposited particles and extending the service life of the filtering elements.

HORIZONTAL CARTRIDGE FILTERS
Industrial horizontal cartridge filters represent one of the most widely adopted solutions in industrial air filtration, thanks to their compact design and ease of maintenance.
The horizontal configuration of the filter cartridges allows for optimal space utilisation and enables quick, safe replacement, even in installations with restricted access. This type of cartridge filtration system is particularly suitable
- Facilities with limited technical space;
- Installations where easy and fast maintenance is essential;
- Applications involving fine and dry dust particles.
Horizontal cartridge filters provide high filtration efficiency and are equipped with automatic pulse-jet cleaning systems, ensuring continuous, reliable operation and long-term performance.
STAINLESS STEEL CARTRIDGE FILTER
Per applicazioni in ambienti aggressivi o dove è necessaria la massima resistenza alla corrosione, i filtri a cartuccia in acciaio inox rappresentano la soluzione ideale.
This type of filter is especially suitable for industries such as
- Chemical and pharmaceutical industries;
- Food processing environments;
- Installations operating at high temperatures or high humidity levels;
- Applications involving abrasive or corrosive dust.
Stainless steel cartridge filters ensure long service life, hygiene, and durability. They can also be manufactured in ATEX-certified versions for use in explosive or hazardous atmospheres, meeting strict safety standards.
ADVANTAGES OF CARTRIDGE FILTERS
Thanks to their compact design and large filtration surface area, cartridge filters offer important advantages:
- High efficiency: up to 99.92% filtration efficiency (B.I.A. certified);
- Compact design: ideal for installations with limited space;
- Large filtration surface area: up to 20 times larger than traditional bag filters;
- Energy and cost savings: reduced maintenance requirements and compressed air pulse-jet cleaning technology significantly lower operating costs;
- Flexibility: modular design and a wide range of filter media to suit all industrial applications;
- ATEX certification: versions available for explosive or flammable dust environments.

These filters are used across a wide range of industrial sectors, including:
FAQ
When is it preferable to choose a cartridge filter instead of a traditional bag filter?
A cartridge filter is the ideal solution for collecting fine, dry and low-density dust when installation space is limited. Thanks to their pleated design, filter cartridges provide a significantly larger filtration surface than filter bags within the same footprint. This makes them the optimum choice for applications such as powder coating, thermal cutting (laser and plasma), sanding, and chemical and pharmaceutical manufacturing processes. Conversely, bag filters remain the preferred industrial solution for coarse, hygroscopic or high-temperature dust.
How does the cartridge cleaning system work and how is its efficiency monitored?
Our cartridge filters are equipped with an automatic reverse pulse-jet cleaning system. An electronic controller continuously monitors the pressure drop (differential pressure) across the filter cartridges through dedicated sensors. When the differential pressure reaches the preset threshold, the system releases a high-pressure pulse of compressed air inside the filter cartridges, dislodging the accumulated dust cake, which then falls into the collection hopper. This ensures continuous operation without production downtime while optimizing compressed air consumption.
Are your cartridge filters suitable for handling explosive dust or installation in ATEX classified areas?
Absolutely. For potentially explosive dusts—such as metal, wood, food-processing or plastic dust—our cartridge filters are specifically designed and configured in full compliance with the ATEX Directive 2014/34/EU.
The safety configuration includes:
- Antistatic filter media (e.g. aluminized polyester) to prevent electrostatic charge build-up.
- Certified explosion vent panels and explosion relief systems to mitigate overpressure.
- ATEX-certified electrical components, valves and properly grounded steel construction suitable for the specific hazardous area classification.
Which filter media are available and how can the correct one be selected for a specific application?
The selection of the filter media depends entirely on the chemical and physical characteristics of the contaminant to be collected.
We use several types of high-quality technical filter media, including:
- Standard Polyester or Cellulose – ideal for general-purpose dry and non-aggressive dust.
- PTFE Membrane (Teflon®) – recommended for extremely fine or agglomerating dust, providing excellent dust cake release during pulse cleaning and filtration efficiencies approaching 99.9%.
- Oil- and Water-Repellent Treatments – suitable for air streams containing traces of moisture or oily substances that could prematurely clog the filter media.
Our engineering team carefully evaluates the operating conditions of each system to identify the most suitable filter media and maximize filter service life.
How often should filter cartridges be replaced and what are the signs of wear?
There is no standard replacement interval, as cartridge service life depends on operating hours, dust loading and contaminant characteristics. Under normal operating conditions and with proper maintenance, filter cartridges typically last between 4,000 and 8,000 operating hours (approximately 1–2 years).
The main indicators that replacement is required include:
- Permanently high differential pressure, even immediately after pulse-jet cleaning.
- A noticeable reduction in extraction airflow at the capture hoods or extraction points.
- Visible dust emissions from the exhaust stack, indicating possible damage or perforation of one or more filter cartridges.
