External float drains mount below air receivers, separators, dryers and filters to discharge condensate automatically without power. A float inside the drain body lifts the valve as condensate collects and reseats it once the body has emptied, so compressed air is not vented in normal service. Ultramax Systems groups the range into receiver and separator drain kits, which include ball valves and strainers and discharge up to 600 L/hr, compact float drains for filters and drip legs, and genuine Omega Air AOK float drains, including stainless steel and 50 bar high-pressure models. All are simple to install and service, and are held in Australian stock.
