Questions buyers ask
What pressure, flow and temperature is it rated for?
This unit is rated for 3,000 PSIG maximum working pressure with 630 SCFM capacity at 100 PSIG differential pressure. The listing does not specify a temperature rating; ask the seller for the minimum and maximum operating temperature range, which varies with seal material.
What gases is it compatible with, and has it been oxygen cleaned?
The listing identifies applications including CNG, LNG/NGL, and general industrial gases but does not specify gas compatibility limits or oxygen cleaning status. Ask the seller whether this unit has been oxygen cleaned and obtain documentation if your application requires it, including verification of materials compatibility and cleaning procedures for your specific gas service.
What materials are the wetted parts?
The housing is constructed from 316L stainless steel with standard Viton O-ring seals. The listing does not specify the filter element material; the referenced 51-230-70 CS coalescing element would have its own wetted materials that should be confirmed with the seller if chemical compatibility is critical to your process.
What should I inspect before putting it into service?
Since this is listed as new 2020 stock, verify that all O-ring seals remain pliable and undamaged. Confirm the housing interior is clean and free of storage contamination, check that NPT threads are undamaged, and pressure test the vessel per your site procedures before introducing process gas.
