Floor Return Inlet — Stainless Cover (TBN02)

TBN02 is a return inlet recessed into the pool floor that distributes filtered water evenly upward from the floor. Its body is made of white ABS plastic and its cover of stainless steel with a chrome front face; Ø50 mm and Ø63 mm diameter options suit installations with different pipe sizes.

The cover can be chosen in AISI 304 (TBN02) for standard chlorinated water, or AISI 316 (TBN02-316) for pools using salt electrolysis, seawater or thermal water. The body is highly resistant to UV light and chlorinated water, and the AISI 316 version also to salt water. The connection complies with the DIN ISO 228 BSPP (DIN 259) parallel thread standard.

Floor return, especially in overflow pools, lets water sweep the entire volume upward from the floor before reaching the overflow channel; it reduces dead zones and helps distribute disinfectant evenly through the pool. The number and layout of inlets are designed according to the circulation flow rate and the hydraulic design principles of EN 16713-2 / TS EN 15288.
