Armstrong See-Thru Drainer (Liquid Drainer/Air Trap)
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 system problem.
Since you’ll know the operating condition of the drainer, you won’t have to 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.
A simple ball float mechanism requiring no electricity to operate, the new Armstrong 1-LDC discharges condensate automatically only when air/gas are present.
That means no air/gas loss as with manual venting.
An Inside Look
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.
Simple ball float mechanism discharges only when condensate is present so it doesn’t waste air/gas
Free-floating valve mechanism assures positive seating so it prevents air/gas loss.
There are no fixed pivots to wear or create friction, and wear points are heavily reinforced for long life.
Stainless steel internals mean corrosion resistance and reduced maintenance.
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 resist corrosion and provide 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.
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.
Compare… and Save the Difference
Seeing is really believing—especially when you compare the Armstrong see-thru drainer with manual venting.
Measure the differences in the time and money you can save with a more efficient
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.
