AUP 21 automatic flushing system for urinal

AUP 21 is an automatic flushing system, delivered as individual set which can be assembled into the majority of the urinals intended for self-priming siphon. Delivery of AUP 21 includes complete material for water connection (corner valve, hoses, electromagnetic valve with sieves, sealing ring with the connecting hose for water jetting) and for electric connection (cable for the connection to source of power supply 12V, 50 Hz – AUP 21 or battery holder with 4 x AA batteries for the battery version AUP 21.B). The whole assembly is very easy.
The electronics scans and assesses processes in the trap and upon the result it directs the device to flush. Only one litre is enough to flush the bowl urinal. If somebody approaches the bowl urinal without using it, the control electronics does not react. It prevents needless flushing in the case of incidental short-term entrance (passing by the bowl urinal, etc.). After 24 hours of no activity, the bowl urinal automatically flushes.

AZP Brno will offer following urinals with this type of flushing system: GOLEM AUP 5-II, NOVA AUP 27, GOLF AUP 28 and APOLLO AUP 29.
The flushing system AUP 21 is intended for social facilities where the user’s comfort and the maintenance of hygiene is required at maximum water savings.
