Thank you for your question. The Delta Rectangular Aerator, Set Screw RP75408 already comes with the Ara Lavatory 567LF-LPU faucet. To reduce the flow rate to .5 GPM @ 60 PSI, you would just need the Delta Flow Restrictor RP73837, installed in the valve. Please review the below Parts diagram for this faucet.
