AM120

This is the factory replacement propeller assembly for the DA-20 Display Aerator. The propeller is the component that actually lifts water into the display plume, so a worn, chipped or fouled unit shows up first as a shorter, lopsided spray and reduced flow before it becomes a service problem. Swapping the assembly restores the original spray pattern and circulation without replacing the whole aerator.

Assemblies are offered to match each DA-20 motor size, and the correct one is chosen from the size options on the listing rather than being universal across the range. Pick the option that matches the horsepower rating of the motor on your aerator - the part numbers differ by size and the assemblies are not interchangeable between them.

One important limitation: these propellers are specific to the DA-20 display aerator. They do not fit AquaSweep units or de-icers, which use a different propeller of their own. If you are not certain which model you have, check the motor nameplate for the horsepower rating before ordering.

No fixed warranty term is published for this item. It is covered against defects in materials and workmanship on arrival, so contact Adventure Motion support with your order number and photos if it arrives faulty or does not match what you ordered, and we will confirm coverage and handle the claim.

Normal wear and consumable service life are not covered, and neither is damage from installation outside the stated compatibility or operating conditions.

Which size do i need?
Match the assembly to the horsepower of your aerator's motor. five options are offered - 1/3 hp, 1/2-1 hp, 1 1/2 hp, 2 hp and 3 hp - and the sizes are not interchangeable, so check the motor nameplate if you are unsure.
Will this fit an aquasweep or a de-icer?
No. these assemblies are for the da-20 display aerator only. aquasweep units and de-icers take a different propeller.
Why would the propeller need replacing?
Propellers wear, chip or get fouled over time. the usual signs are a shorter or uneven spray and noticeably less water being moved than when the aerator was new.
Does replacing it change the aerator's performance?
A correctly matched assembly returns the unit to its original spray pattern and flow rate. it does not alter the motor's horsepower, voltage or amp draw.
