Paint Strainer & Spray Gun Filter Screen in 304 Stainless Steel (AISI 304 (1.4301)) is used for straining paint, coatings and inks at the spray gun, pump inlet and cup so lumps, skins and grit do not block tips and spoil the finish. The alloy gives good general corrosion resistance in atmosphere and fresh water and is essentially non-magnetic (annealed), with a practical service limit of approx. +450 °C continuous.
