Cache Aerator Sizing Guide Video 

1) Determine faucet aerator housing size

For standard (non-cache) aerators

The edges from the flat side of the coin should still be visible from the top when the coin is placed underneath an aerator. 

For cache aerators (hidden aerators) 



2) Determine if you need male or female (if you need a housing)

NRG carries Dual threaded aerators that will fit both male & female standard size faucets.

3) Choose stream type and flow rate

New Resources Group offers aerators in a variety of stream types and flow rates to suit different applications.  

Aerated stream

Aerators introduce air into the water stream to produce a larger and whiter stream soft to the touch and non-splashing. Aerators are the usual choice for residential faucet applications. NRG water saving aerators come in low flow rates to provide maximum savings.  Our aerators. 

Laminar stream

Laminar stream straighteners produce a non-aerated water stream. Ideal for high flow applications or health care facilities (no mix water/air) NEOPERL® laminar spout-end devices deliver a crystal clear and non-splashing stream.

Multiple Laminar Spray 

When the flow rate is too low to produce an aerated or laminar stream a spray device is used to produce a miniature shower pattern to provide full coverage of the hands during washing. Great use in kitchens. Sprays are recommended for use in public lavatories. 

Flow performance

Water & Energy Conservation products cover a wide range of flow rates to meet the needs of residential, commercial and institutional faucet applications. The EPA recommends aerator cleaning every six months and annual replacement.

Water & Energy Conservation provides quality low flow water & money saving aerators and products.
