Two Exhaust Runs
trying to deal with the problem of exhausting a two motor system
with two 2 inch exhaust pipes coming out of the unit from the same side, and wandering if there is an alternative to the two individual lines having to be run seperately? When is there going to be made a special coupling or adaptor to deal with this problem or do you know of one? how about a 3 inch cover for a drainage pipe with the same flapper as the two inch?
Hello, just to start, please remember to keep an exhaust run on any central vacuum to around 15 feet to prevent back pressure. When it comes to two motor units with two exhaust ports, we feel it is more convenient to use the pipe, fittings, and vents already available for and easy to use with an installers supply of materials. Run the lines neatly together and use two vents as the pipes separate as they reach their exit points. Having said that, there is not a fitting for combining two runs into a single larger one. But we have heard of installers getting creative with 4 inch and drilling holes in a cap for the two runs. Also using 4 inch dryer duct and filling the space with foam.
