Does this aerator come with a control panel?
Only the three-phase models. The 3.3AF and 5.3AF include a CA-3235 panel. Every single-phase model - 2400AF, 3400AF, 3400HAF, 4400AF, 4400HAF, 8400AF, 3.1AF and 5.1AF - ships without one.
If you are buying single-phase, budget for a control panel separately.
What size surface aerator do I need?
Size on surface acreage and average depth. As a working rule from our own installs, plan on roughly 1 to 1.5 HP per surface acre for meaningful oxygen transfer.
Send us your acreage and depth and we will confirm before you order.
What is the difference between the 3400AF and the 3400HAF?
Voltage. Both are 3/4 HP single-phase, but the 3400AF runs on 120V and the 3400HAF on 240V. The same applies to the 4400AF and 4400HAF at 1 HP.
The H prefix is the tell. Check the supply at your power source before ordering - it is a different unit, not a plug swap.
Surface aerator or diffused aeration?
Depth decides it. Surface aeration works the top few feet and covers a wide area per horsepower. Diffused aeration lifts the entire column.
Under about eight feet a surface unit is usually enough. Deeper than that, look at diffused aeration.
What warranty applies?
Two years on the 2400, 3400 and 4400 series. Three years on the 8400AF and every 3 HP and 5 HP model.
Because we are an authorized dealer running our own repair centre, warranty work stays in Canada.
Can I run it through a Canadian winter?
A surface aerator is not a de-icer, but paired with a thermostat panel it can keep water moving as temperatures drop.
If ice prevention around a dock is the actual goal, a purpose-built de-icer is the right tool.
