Our positive seal spring loaded elements were born from the need to provide high efficiency filtration in compressed gas systems with substantial vibration and/or high pressure swings during start up. The “SL” elements have a stainless steel helix welded to base to ensure a stable fit, while a double O-Ring provides a leak tight seal for peace of mind filtration.
Many of our “SL” elements come with a final stainless steel outer mesh element for a completely encapsulated particulate or coalescing filter – ultimate reliability that has been field tested. These are available across our product line, and we also produce retro-fit kits for propriety brands.

Because high durability stainless steel filters have a tremendous amount of adsorptive stainless steel surface area the surface will adsorb or capture H2S, mercaptans, and other sulfur compounds; making analyzers like CEMS (continuous emission monitors) ineffective. Sulfur adsorption can hold up accurate CEMS measurements by up to 90 minutes or more.
Bubblers are used on some environmental systems as part of the calibration process, which is called an interface check. The operator passes a known concentration of gas through the water-filled container (bubbler). This humidifies the gas so the analyzer may read it. It is typically done before each test to ensure that the analyzer is working properly. The operator will compare the analyzer’s reading with the known concentration to make sure they are equal.
