Floor Return Inlet — Full ABS (TBN01)

TBN01 is an economical, entry-level floor return inlet made entirely of ABS plastic. It is recessed into the pool floor and contributes to water circulation by distributing filtered water upward from the pool floor.

The acrylonitrile butadiene styrene (ABS) body is lightweight and resistant to UV light and chlorinated water. The white body colour gives a clean look that matches the pool floor. The connection complies with DIN ISO 228 BSPP (DIN 259), the widely used parallel (cylindrical) thread standard for PVC pipe and nipple connections in pool pipework, sealed with a gasket.

For projects that want a stainless cover with a chrome front face, the TBN02 series can be chosen. The number and distribution of floor return inlets are determined by the circulation flow rate and pool geometry using the hydraulic design principles of EN 16713-2 / TS EN 15288.
