Kaeser Eco-Drains prevent the water, oil, and dirt trapped by compressed air tanks, moisture separators, dryers, and filters from building up and contaminating your product and expensive equipment. Controlled by reliable capacitance sensors, these energy-saving drains remove contaminated condensate but not valuable compressed air. The robust aluminum housing and patented pilot air-controlled valve technology ensure many years of reliable service when subjected to harsh condensate. Other features include dry contacts for central alarm signaling, LEDs, and a test button. For more information visit www.kaeser.com or call (800) 777-7873.
