4IN AL EXHAUST/CONDENSATE ELBOW

Condensate is a common byproduct from the operation of refrigerators, freezers, and ice machines. Condensation occurs when water is changed from it's gaseous form (water vapor) into liquid as it passes over the evaporator coil. Typically this can occur when warm air comes into contact with cold surfaces where water droplets will form. A condensate drain system is the exit route for this moisture as is collects in condensate the pan, and out through the condensate drain line.

An elbow is installed between two lengths of pipe (or tubing) to allow a change of direction, usually a 90° or 45° angle; 22.5° elbows are also available. The ends may be machined for butt welding, threaded (usually female), or socketed. When the ends differ in size, it is known as a reducing (or reducer) elbow.

An exhaust or exhaust system is used for venting gases from cooking equipment. The exhaust is part of a system designed to vent hot gases, steam and smoke from a stove, oven or boiler to the exterior or into a supplemental vented hood . An exhaust my be vertical or channeled, ensuring that hot gases flow smoothly by drawing air into and out of the combustion system through convection, or they may be fan forced.
