PneumaticPlus SAD402 Series Water Trap Valve, Automatic Drain, Metal Bowl with Sight Glass, 10 Micron Automatic drain for removing accumulated liquid from a compressed air system 1/4" NPT or 1/2" NPT Female Thread ports for use with existing air piping Float Drain with 1/4" Tube Connection (Push-to Connect Fitting) Metal Bowl w/ Sight Glass 10 Micron Element Float-style drain for automatic liquid discharge without electricity Manufactured In Korea, 1 Year Limited Warranty PneumaticPlus SAD402 Series Water Trap Valve with Automatic Drain offers a cost effective solution for filtering particulate and moisture in your airline. The SAD402 Series uses a 10 Micron Element as the standard filter element and utilizes an automatic float drain for liquid discharge and is suitable for removing accumulated liquid from a compressed air system. It does not require electricity or consume air flow for operation. The SAD402 comes in either a 1/4" NPT or 1/2" NPT female inlet and requires a minimum air flow of 400 L/min for operation. It has a maximum drain discharge rate of 400 cc/min, an operating temperature range of 23 to 140 degrees F, and an operating pressure range of 14.5 to 145 pounds per square inch (psi). This automatic drain is suitable for use in compressed air applications such as in a machine shop or assembly line. Compressed air filters remove pollutants and submicronic contaminants from clean air in compressed air handling and preparation systems. Clean compressed air provides and controls energy, conveys materials, and is critical to the safe operation of equipment in many industries. Compressed air filters remove particulates (dirt), oil, water, and oil vapor. They can be combined with other units, integrating with either a regulator, which controls excess pressure for better performance, or a lubricator, which adds oil mist to the air, or both. Compressed air filters are used in a wide range of applications, including food processing, electronics, heal
