PTFE Filter Housings

The PTFE housings are designed especially for use in high chemical resistance and low adsorption applications. They accept disposable fluorocarbon elements for coalescing and particulate service, and sintered PTFE elements for particulate filtration only. The housings come standard with Viton O-rings, however Kalrez is recommended for the best chemical resistance.

A Pyrex glass bowl version is available which allows at-a-glance monitoring of the filtration process.

The assemblies may be utilized in gaseous or liquid filtration by simply installing the appropriate element. PTFE elements are recommended for liquid service with an outside to inside flow pattern so that the integral support core provides added strength and element life can be visually monitored.

Please keep in mind that the maximum pressure is 100 PSIG and the maximum temperature is 300°F regardless of O-ring material. We also offer exotics such as Monel, Hastelloy, Titanium and others which provide higher temperature and pressure ratings.

At the heart of our filter products is the filter element. Choosing the correct element insures proper results for your specific application:

Disposable Microfiber Elements

Disposable Microfiber Elements are most commonly used since they offer exceptional filtration, high flows with minimal pressure drops, and excellent chemical compatibility. These are ideal for use in sample conditioning, instrumentation, CNG, and Emission/Environmental service.

  • For Coalescing (liquid removal) and particle collection use our grade “C”. We recommend starting with the 70C which is rated at 95% efficient at 0.01 micron which provides outstanding filtration, at high flow rates.
  • For Particle removal only use grade “K”. We recommend starting with the 70K which is rated at 95% efficient at 0.01 micron which provides outstanding filtration, at high flow rates.
  • For Particulate removal above 300°F (150°C) use grade “S”.

Sintered PTFE

Sintered PTFE elements are used where only pure PTFE may contact the sample. They should be used in our PTFE series of housings based on the stainless steel models. Model 122P, 122PG, 130P, 130PG, 132P, 132PG, 142P.

Standard microns available: 3 and 25.

Sample Conditioning Filters

  • For Aggressive Service
  • Use Either Microfiber, or PTFE Filter Elements
