"Expect many enjoyable experiences!" David M. Armstrong
Did you know: Humidification is the process of adding moisture to the air.
Free-Floating Lever Dual Gravity Drain Traps
Armstrong free-floating lever dual gravity drain traps are identical to Armstrong’s 2-LD, 3-LD and 6-LD, except float weights are modified to make them suitable for draining water from a light liquid. If you wish to use them for draining any liquid with a specific gravity other than 1.00, consult the Armstrong Application Engineering Department.
Floats for dual gravity drain traps are weighted with quenching oil, which, in the unlikely possibility of float failure, may be dispersed through the system. If this is a hazard, consult the Armstrong Application Engineering Department.
