1-LDC—A See-Thru Body So You’ll Know When It’s Working Benefits You Can See Reduced maintenance Efficient operation Stainless steel internals mean corrosion resistance and reduced maintenance. Simple ball float mechanism discharges only when liquid is present so it doesn’t waste air. Positive seating Free-floating valve mechanism assures positive seating so it prevents air loss. There are no fixed pivots to wear or create friction, and wear points are heavily reinforced for long life. See-thru body means you can observe changing conditions as they occur. See a problem in the making—instead of having to deal with it after the fact. In-line repairability Corrosion resistance Liquid Drainers In-line connections and an O-ring seal make for quick, easy repairs without dismantling piping. Just unscrew and remove the body for maintenance. Long-lasting polysulfone body and reinforced nylon cap weigh less than 20% of cast iron liquid drain traps. Rugged polysulfone resists corrosion and provides long, trouble-free service life. Reduced need for cleaning Recessed dirt pocket gives dirt a place to accumulate away from the valve seat. Valve seat is 1-1/4" above the dirt pocket. Compared to other ball float drain traps, the Armstrong 1-LDC reduces dirt fouling and needs less frequent cleaning. Simplified installation Optional horizontal or vertical inlet with horizontal outlet eliminates the need for extra fittings. Makes installation in existing systems easier. Vertical inlet is 3/4" to accommodate air venting. Requires no electricity. NOTE: The Armstrong 1-LDC is not recommended for extremely dirty systems or those with heavy oil carryover. The drain trap should not be used in an environment where there are high levels of ketones or chlorinated or aromatic hydrocarbons. Designs, materials, weights and performance ratings are approximate and subject to change without notice. Visit armstronginternational.com for up-to-date information.

1-LDC—A See-Thru Body So You’ll Know When It’s Working Now, you can literally see what you’ve been missing—the early warning signs of a drain trap or system problem. Since you’ll know the operating condition of a drain trap, you won’t waste time and money scheduling maintenance that isn’t needed. In other words, you will be able to react to a condition before it becomes a problem. Moisture in a compressed air system causes a variety of problems— everything from dirt fouling and potential corrosion to water hammer. Getting the water out—automatically, reliably—builds greater efficiency into...
