An Auto Drain for Filter is an essential component used in compressed air systems to automatically remove accumulated moisture, oil, and contaminants from air filters. It helps maintain clean, dry air flow, ensuring efficient performance and longer life of pneumatic equipment. Auto drain valves are commonly installed at the bottom of air filters (FRL units), moisture separators, and air receivers. These drains eliminate condensate without manual intervention, reducing maintenance efforts and preventing system damage caused by water accumulation. They are available in mechanical (float type) and automatic timer-based versions, depending on application requirements.
