What is the difference between air and drain traps?
Air traps are used to remove condensate from the ends of air piping, from receiver tanks, etc. Some models have larger orifices to facilitate the removal of high viscosity condensate with entrained oil or scale. As corrosion resistance is not of particular importance, trap bodies are typically constructed of cast iron. Drain traps, as defined by TLV, are traps which are available in two forms – for air or non-flammable, non-toxic gas applications. Drain traps are used to remove condensate from air or non-flammable, non-toxic gas systems requiring a tight seal. For this reason, TLV drain traps employ 3-point seating to provide a tight seal even under low condensate load conditions. Products constructed of materials suitable for use on high pressure lines are also available.
