  • Inclination of the screen compared to the vertical: 15°.
  • Spacing from 12 up to 60 mm.
  • Frame is made with metal plates with a thickness of 3‐4 mm.
  • Gear‐motor shaft and crowns are manufactured in micro alloy steel.
  • Translation chains type rollers chains are manufactured in stainless steel AISI 304 or AISI 316.
