APTA is due to enlarge the possible choice of the right linking of the inlet valve with the electric mounting boxes which are in the rest of the house (Bticino, Vimar, Legrand, Gewiss, etc.).

The APTA CONTACT is endowed with electrical contacts in order to start the central suction by inserting the flexible hose (code AC073-AC084) in the inlet valve or through the interrupter which is placed on the curved fitting of the hose (code AC046-AC050)

N.B. All the inlet valves type APTA CONTACT are supplied without electric mounting box.
