All three are sintered or pleated-mesh stainless steam filter elements with the same 1/5/25 µm absolute retention grades. They differ in end-cap construction, filter area, maximum Δp and operating temperature — not in what they remove.
Weldless sintered 316L. Bonding material Plastic Steel; > 150 °C: welded end caps. The standard choice for culinary and clean steam. The range is −20 °C to 210 °C.
Identical sintered 316L element to P-GS, but with welded end caps. Welded end caps for temperatures above 150 °C. Filter medium and end caps are made of stainless steel. Solid-particle filter — no pre-separator, no condensate function. Regenerable by ultrasonic bath or back-flush.
Pleated stainless wire mesh, same 1/5/25 µm absolute retention as P-GS/P-GS VE. Three times the filter area (0.18 m²) and twice the maximum Δp (10 bar). For high-flow, heavy dirt-load, pulsed or high-pressure steam duty. Regenerable by ultrasonic bath or back-flush.
All three filter to the same absolute grades. The decision is about construction, temperature and duty cycle.
