Our low-pressure stainless steel housings are ideal for gas analysis, emissions, CEM and sample process filter applications where continual monitoring is required. Although all the stainless steel housings eliminate the monitoring capabilities, they do provide a cost effective filter solution to systems requiring all stainless wetted parts.
The housings have minimal annular volume to reduce lag time and carry over. The 1/4″ drain port in the base, also allows these housings to be utilized as by-pass and slipstream filters.

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”.
Stainless Steel 5-Layer Mesh Elements
Stainless steel elements (SS) are designed for the filtration of heavily contaminated gas samples, CNG, and liquid streams since they are recleanable by back flushing or ultrasonic cleaning. Standard microns available: 0.5, 1, 3, 10, 25, 50, 100, and 200.
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: 3,10, and 25.
Sintered Polyethylene (PEL)
Sintered polyethylene elements (PEL) are used only in non-corrosive applications to remove bulk contaminates. Standard micron sizes available: 10, 25, and 75.
