"g" series cartridges for natural gas
These cartridges have been used for about 40 years for the filtration of natural gas and hydrogen in decompression cabins. The standard filtration degree is 5 microns, new studies and tests have allowed us to expand the range with new materials and filtration grades.
The “G” series cartridges are used to filter natural gas and hydrogen in decompression cabins.
The effectiveness and safety of use of these cartridges, their high pleated filtering surface, allows the filtration of all the dust and mechanical particles that come into contact with the filter media.
The standard filtration degree is 5 microns, new studies and tests have allowed us to expand the range with new materials and filtration grades.
disc filters
In recent years, the advent of new generations of gas meters has made it necessary to create new interflange filters to protect the sensitive parts of the meters (pistons, rotors, etc.). The passage of dirt particles can in fact damage the moving parts and the measuring chambers.
TECNO FILTRI SRL leader in the natural gas filtration sector, has designed and built these interflange discs using suitable materials to create a product of absolute quality able to meet the needs of customers.
FILTER CARTRIDGES FOR REFINED PETROLEUM PRODUCTS, CHEMICAL SOLVENTS AND SEA WATER
These cartridges have been developed to allow the filtration of solid particles present in petroleum refining derivatives.
They are completely produced in 316L stainless steel and used for amines, fuel oils, alcohols, gasolines and sea water.
COALESCENT FILTER ELEMENTS
Filter elements designed and studied for the removal and separation of contaminants such as: oil, solid particles, and hydrocarbon vapors, present in the air and gas, ensuring a residual vapor up to 0.01 mg / m³.
The continuous search for new filter media has allowed us to optimize our cartridges by giving them a high filtering power capable of retaining impurities down to 0.01 micron.
TFJ COALESCENT FILTER CARTRIDGES
TFJ 536 cartridges are used in the forced filtration of natural gas and air and are responsible for the elimination of solid and liquid particles.
They have a great capacity of accumulation of pollutants and a great resistance to crushing by means of the high resistance internal protection.
The sense of filtration occurs from the outside to the inside and are available with filtering capacities from 1 – 3 – 5 microns.
DEDUSTING CARTRIDGES
These filter cartridges are used for the separation of dry impurities suspended in the air and are mainly used in dedusting, but they can also be found in blowers, vacuum pumps and air compressors.
The attention and care in the choice of materials and the high professionalism of the staff make it possible to create high quality filter cartridges.
vpz and zpz series cartridges for biogas
These cartridges were created to meet customer needs for natural gas and biogas filtration. Biogas are a mixture of various types of gases, mainly composed of methane, produced by bacterial fermentation in anaerobic (absence of oxygen) organic residues from plant or animal residues.
CARBON CANISTER
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.
ACTIVATED CARBON CARTRIDGES
Activated carbon cartridges are designed to remove liquid impurities in gas treatments.
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.
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.
sintered filters
Alongside the production of filter cartridges, to be close to customer needs, our company also offers pressure control devices for pilot plants and a wide range of sintered filters.
The latter are characterized by narrow tolerances, and by a wide range of stainless steel and bronze filters.

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.
COALESCENT FILTER ELEMENTS
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.

CARBON CANISTER
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.

sintered bronze filters
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
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.
