A strong, light construction: a welded carbon-steel body. Every unit passes strength and tightness tests. Water velocity is up to 0.5 m/s in the branches and 0.1–0.2 m/s inside the body.

Carbon steel, welded construction — strong and light.
Checked for strength and tightness.
No more than 0.5 m/s — sized per the table.
0.1–0.2 m/s: air and sludge have time to separate.
