This is the genuine Bosta replacement air suction unit (diagram part No. 23) for the STP series counter-current swimming system. It controls the volume of air drawn into the water jet, allowing users to fine-tune the intensity and feel of the counter-current flow directly at the nozzle panel.<\/p>\n
Designed exclusively for Bosta STP series counter-current systems, including the STP-2200, STP-3000, and STP-4000 variants. Always verify your model’s exploded parts diagram before ordering, as this component is specific to position No. 23 in the STP assembly.<\/p>\n
Using an authentic Bosta air suction unit ensures correct airflow regulation and a precise fit within the front cover panel assembly. Third-party alternatives may not seal or regulate correctly, potentially degrading jet performance or causing air leaks that affect swimming comfort and system efficiency.<\/p>\n
This unit is located in the front cover panel of the STP system alongside the nozzle and pneumatic switch. Replacement is straightforward for a qualified pool technician familiar with the STP assembly; correct reassembly ensures the air-to-water mixture remains fully adjustable for the end user.<\/p>","protected":false},"excerpt":{"rendered":"
