AC Tanks are designed to be ergonomically friendly for the installer. Our exclusive in house head design is dimpled “inward” to allow for plenty of easy hand clearance. When combined with a sturdy, recessed steel handle, our tanks help installers avoid a potential “knuckle-busting” injury when moving tanks into their final locations.
