AER GD

Low speed surface aerator

Specifically designed for fixed or Float mounting which allow impeller immersion to vary in accordance with flow levels and associated oxygen demand. Ideal for Oxidation Ditches and Pocket ASP’s.

Components

1.1 – 160KW Motor Sizes

40- 130rpm geared drives

4+6 Blade, LH + RH impellers

Epoxy coated MS, SS or FRP impeller options

Advantages

Maintains aeration efficiency and can be operated at variable speeds
Ideal for activated-sludge systems with baffles or draft tubes for deep tanks
Aerobic digestion processes unscreened plants
High oxygen transfer intensive mixing
Easy access and maintenance robust design

Options

Four impeller options – 4-blade, to produce circulation in oxidation ditches, and 6-blade, for higher efficiency: LH or RH.
Fixed bridge/platform mount or floating
Vertical operation only
One x Surface drive
Fixed or minimal WL variation
