Step 5: Stream type and flow
Choose the right one for your needs
Laminar stream straighteners produce a 
crystal clear and non-splashing stream (no 
mix water/air). 
When the water pressure is too low to produce 
a aerated or laminar stream, a spray device is 
used to produce a miniature shower pattern 
to provide full coverage of the hands during 
washing. Recommended for use in bathroom.
Aerated stream introduces air into the water 
stream to produce a larger white stream, soft to 
the touch and non-splashing. Aerated stream are 
the usual choice for residential faucet.
90% of faucets use regular 
size aerators, while less than 
10% (lavatory faucets) use 
small size aerators.
