In our range of cartridges any model can be modified in size according to the needs of our customers.

It is the user’s responsibility to determine the suitability of the product required for a specific use and its adaptability to their own use procedures.

These cartridges have been designed to create a coalescence effect, the dirty gas passes through the filter element from the inside to the outside, the solid particles are retained inside the filter element thanks to a pre-filter while the liquid particles are agglomerated by the filtermedia. The force of gravity then makes them flow to the bottom of the vessel, where they are eliminated by purge valves.

Each of our products is rigorously checked during the processing stages and tested at the end of the production cycle, where the marking operation takes place for product identification and subsequent packaging.

The pleated filter media gives the cartridge a high filtering surface and a low pressure drop and consequently a longer operating period.

These cartridges have a very high filtering capacity and are used for the filtration of air or technical gases.

The multilayer that composes them makes them capable of stopping tiny solid particles down to 0.1 microns.

They are supported by adequate protections that guarantee high differential pressures.

To obtain efficient filtration, low speeds must be considered when designing the vessel to allow the fabrics to work at their best.

Furthermore these cartridges have coalescing power for the separation of oil / water from gas.

These new generation cartridges have a very high filtering efficiency and protect equipment such as gas turbines where dust that can damage the moving parts is not allowed.

The new generation fabrics, BIA-USGC certified, used in the construction, provide for a Teflon treatment of the filter media which ensures absolute resistance of the material to high temperatures, traction and cutting of the fabric, also giving it a valid coalescing power.

Appropriate shatterproof protections guarantee very high differential operating pressures.

They have a filtering capacity of 5 microns (standard).

The filter fabric is BIA-USGC certified and is thermo-stabilized on the inlet side for better dust detachment.

Direction of filtration (standard) from outside to inside.

At the request of the customer when there are high pressure differences, the cartridge is internally armored with a reinforcement cage.

These new generation cartridges have a filtering efficiency of 5 microns.

The filtering fabric that composes them is impregnated in a chemical solution containing fluorinated resins and PTFE.

This treatment gives it protection from chemicals, acids, protection from hydrolysis, greater durability, the cartridge is made water-repellent and creates a coalescence effect that gives it better release thanks to the non-stick action.

To allow efficient filtration of the biogas, the cellulose impregnated with resins and reinforced with polyester fibers is pleated to obtain a greater filtering surface and therefore a greater accumulation of particles. The filter media is supported both internally and externally by galvanized iron protections, they have been designed to provide the filter element with a flow surface compared to other types of materials.

These cartridges can be cleaned with low pressure compressed air in an emergency to make them reusable.

However, the pores of the filter will still be clogged with dirt particles, and the cartridge will still need to be replaced in the short term.

Activated carbon filters, unlike most filters that capture solid particles and create a differential pressure, are intended to remove liquid impurities. The absorption of the molecules by the carbon does not cause a significant change in the differential pressure.

The major impurities retained by coal are: Amine, Glycol, Water, Oli, Selexol, Sulfinol.

They are preceded by a pre-filter to stop solid particles that could compromise the efficiency and life of the carbon and it is usually recommended to also insert a filter downstream to keep the possible leakage of tiny particles of carbon. All charcoal filters contain 100% virgin granular activated carbon made from charcoal which undergoes a high temperature steam activation process. This process maximizes the absorption zones for high and low molecular weight impurities.

MATERIALS

The materials that compose them guarantee a maximum operating temperature of 150 ° and a flow rate (recommended) of 4.92 Ipm per carbon filter. Different models are built depending on the vessel in which they will be mounted (see button under the product photo).

Bronze filters are filter elements that have good resistance to sea water and can be used in the hydraulic field.

The bronze filters are obtained from a mixture of powders placed inside a mold, subsequently heated in a controlled atmosphere oven, by sintering.

Sintered stainless steel filters are the ideal choice for applications and processes where high resistance to corrosion and high temperatures (up to 450 ° C) is required. Through the use of stainless steel it is possible to obtain filters with a maximum external diameter of 200 mm and a maximum length of 1,000 mm.

The molding takes place at room temperature, while the sintering process takes place at high temperatures in a neutral atmosphere.
