AstralPool Basic NL is a complete counter-current system for concrete pools with a polished AISI-316L stainless steel front cover and a 5.5 HP three-phase pump. With a 60 m³/h stainless suction inlet and a multi-directional water-air nozzle it produces a current adjustable between 27 and 40 m³/h, and it is supplied with a power control box.
Basic NL is a counter-current kit built into concrete pools that lets swimmers train without moving along the pool. The front cover and all visible parts are polished AISI-316L stainless steel; the adjustable water-air return nozzle also provides a massage effect alongside the current.
The system consists of an AISI 316 stainless steel water-air return nozzle, an AISI 316 stainless steel suction inlet rated at 60 m³/h, a 5.5 HP pump and a power control box. The flow can be adjusted between 27 and 40 m³/h; the system runs on three-phase power and is operated from the poolside with an on/off button.
The nozzle set is interchangeable with the 11499 and 11014 nozzle sets. The optional 65535 stainless steel grab handle allows the swimmer to hold position against the current while exercising.
