FINITE

FINITE coalescing filters are designed to remove oil aerosols, water droplets, and particulate matter from compressed air. They are available in ratings such as 1 micron and 0.01 micron, with flow capacities up to 170 scfm. FINITE activated carbon filters use carbon media to target hydrocarbon vapors and odors, typically with a 3 micron rating and flow capacities around 105 scfm. In practice, a coalescing filter is often installed upstream of a carbon filter to remove bulk contaminants first, extending the carbon media's service life. Selection depends on the specific contaminants present and the required air quality.

FINITE sterile compressed air filters are available with 3/4 in NPT and 1 in NPT connections. Flow capacities range from 105 scfm to 170 scfm, depending on the model and filtration rating. For example, the SN3L-AUN carbon filter has a 3/4 in NPT connection and 105 scfm capacity, while the SN4L-10DSN coalescing filter has a 1 in NPT connection and 170 scfm capacity. When selecting a filter, match the connection size to the existing piping and confirm that the flow capacity meets or exceeds the system's maximum demand at the expected operating pressure.

Maximum operating temperature varies by FINITE model. Some units are rated to 175°F, while others are rated to 250°F, 350°F, or 450°F. Maximum operating pressure is up to 250 psig on select models, such as the SN4L-10DSN and SN4L-10CUN. Always verify the specific model's ratings against your system's operating conditions. Operating above the rated temperature or pressure can compromise filter integrity and performance. If your application requires higher ratings, review the full FINITE catalog for models with appropriate specifications.

To select a FINITE replacement element, identify the existing housing model or the original element part number. Key parameters include connection size (3/4 in or 1 in NPT), filtration rating (100 micron, 3 micron, 1 micron, or 0.01 micron), flow capacity, and maximum operating temperature. The element must match the housing's design to ensure proper sealing and flow. If the original part number is not available, provide the housing dimensions, connection type, and application requirements. 3G Electric can help cross-reference available FINITE SKUs to the required specifications.

Yes. FINITE manufactures sterile compressed air filters with stainless steel construction, which supports cleanliness and corrosion resistance. These filters are used to remove oil aerosols, water droplets, particulate matter, and hydrocarbon vapors from compressed air systems. Models with 0.01 micron coalescing ratings are available for applications requiring very fine filtration. Stainless steel housings are compatible with many industrial environments and can be cleaned or replaced as needed. For sterile applications, consider the full filtration train, including coalescing and carbon stages, to achieve the required air quality.

A FINITE water separator, such as the SN4L-100WSUA, is used to remove bulk moisture and larger particulate from compressed air. It has a 100 micron filtration rating and a 1 in NPT connection, with a flow capacity of 170 scfm and a maximum operating temperature of 120°F. Water separators are typically installed at points where condensate accumulates, such as after the compressor and intercooler, to protect downstream coalescing and carbon filters from excessive liquid loading. They are part of a multi-stage filtration approach that extends the life of finer filters.
