FILTRA VIBRACION, S.L manufactures a wide range of laboratory sieves with diameters from 60 to 600 mm, with top quality AISI 304 or AISI 316 stainless steel for the frame, AISI 304 for the perforated plates, and AISI 316 for the metal meshes, providing excellent durability and high resistance to corrosion.

They are all manufactured in strict compliance with UNE, ISO, ASTM, AFNOR, BS, etc. national and international regulations. The FILTRA Quality Management System for the manufacture of these sieves is certified by TÜV NORD, in accordance with UNE-EN ISO 9001:2000 regulations.

They are manufactured in two pieces, allowing the mesh to be changed when it has deteriorated or does not meet the regulations. The interior sieve surface is totally flat to prevent the accumulation of residue and dirt. Cleaning is very fast and easy.

In addition, we can make a specific and deeper test in our laboratory, accredited by ENAC, which certifies the conformity of the metallic meshes and perforated plates according to the manufacture standards.
