American Standard 1.0 gpm/3.8 L/min Pressure-Compensating Vandal-Resistant Aerator With Key - AMS-M922996

It flows 1.0 gpm (3.8 L/min), and it is pressure compensating, so that rate holds steady instead of climbing on high-pressure lines or dropping off on weak ones. For a facility standardizing restroom lavatories on a low-flow spec, that consistency across floors and risers is the point of the pressure-compensating design rather than a plain 1.0 gpm insert.

A standard aerator unscrews by hand or with pliers, which is how they walk out of school, park, and transit restrooms. The M922996 is a vandal-resistant type that requires a key to install or remove, and the key ships with it. For property managers and MRO buyers dealing with repeat aerator theft or people pulling them to defeat the low-flow spec, that key-only removal is the fix.

Yes, the key is included with the aerator. You do not have to source a separate tool to install it. Keep one spare key with the maintenance kit, since without it the aerator cannot be pulled for cleaning or descaling.

Faucet only. The M922996 is a lavatory faucet aerator, threading into the end of the spout. It is not a shower flow restrictor and is not intended for showerheads or hose bibbs.

That is the usual reason for buying it. Swapping an older 2.2 gpm aerator for this 1.0 gpm pressure-compensating unit cuts the delivered flow at the spout without touching the faucet body or the supplies, which is the cheapest route when a building is chasing a water-use reduction across a lot of lavatories. Because it is the vandal-resistant style, occupants cannot back it out and put the old one in.

Chrome, ordered under manufacturer part number M922996-0020A. On a vandal-resistant aerator only the outer rim shows once it is threaded into the spout, so chrome reads as a neutral match against most brushed and polished lavatory faucets in a commercial restroom.
