PTFE filter housings for air and gas filtration

For applications with 1/8" and 1/4" lines

PTFE filter housings

PTFE filter housings

COGA (Contec gas and air filters) filter housings were designed for applications with 1/8" and 1/4" lines for which PTFE material must be used. The FF111 housing system is especially good for applications in which reaction time is important.

Standard COGA housings have NPT connections and FKM seals. Other seals, such as those with BSPT and BSPP connections, are also available as an option. Because of PTFE's properties, the housing is reinforced with a stainless steel ring on the filter head.

FAQs

PTFE is the abbreviation for “polytetrafluoroethylene”. PTFE is a linear polymer composed of fluorine and hydrocarbons. This semi-crystalline fluoroplastic has an extremely strong bond between the carbon and fluorine atoms. Colloquially, this plastic is often referred to by the trade name Teflon, owned by DuPont. PTFE is highly heat-resistant.

Its outstanding thermal and chemical resistance make PTFE one of the most versatile plastics in air, gas, and liquid filtration. In the Contec filter range, PTFE is used in membrane filters, cartridge filters, and the filter housings themselves.

PTFE filter housings offer extremely high chemical resistance to acids, bases, and solvents. They are characterized by high temperature resistance (up to 150°C), hydrophobic properties, durability due to low friction and abrasion resistance, and ease of cleaning. PTFE filter housings are ideal for sterile and gas filtration.

PTFE is the material abbreviation for “polytetrafluoroethylene”. Colloquially, this plastic is often referred to by the trade name Teflon® from DuPont. PTFE is a linear polymer composed of fluorine and hydrocarbons. This semi-crystalline fluoroplastic features an extremely strong bond between the carbon and fluorine atoms. PTFE is highly temperature-resistant.

Due to their extremely high chemical resistance, temperature resistance (up to 150°C), and hydrophobicity (water-repellent properties), Contec PTFE filter housings are primarily used in the chemical industry, pharmaceutical production, semiconductor manufacturing, and gas and air filtration. Contec PTFE filter housings are ideal for aggressive solvents, acids, alkalis, and sterile applications.

Drain valves on filter housings are used for controlled emptying, pressure relief, or condensate drainage. This allows the housing to be emptied, for example, before a filter change, or for contaminants to be drained without having to interrupt the filtration process.

Depending on the application, drain valves range from simple manual valves to automatic systems. Common types include manual drain valves, automatic float-type drain valves, electronic solenoid valves, and pressure relief valves.

The PTFE filter housing essentially consists of the upper housing (head) and the lower housing (sump/cup), which together enclose the filter element. Between the head and the sump is a gasket, the material of which varies depending on the filter medium. The filter housing is supplemented with connections (inlet/outlet), brackets, etc.

PTFE filter housings offer a wide range of connection options, primarily as female threads in inch sizes ranging from 1/8 to 3". Typical connection types include inch threads (BSPP, BSPT, NPT).
