[Shop-talk] air line system install

[Pat Horne]

Don’t know specifically on air lines, but sewer line recommend fall is 1/4”/foot with 1/8”/foot being the flattest slope. Remember that this slope is based on solid waste flow. 
My air lines are hard copper with a slope of 1-1/2” in 20 feet. Even if the line is level, opening up the drain on the air line should produce enough flow to pull the water out of the lines. 

Peace,
Pat

I’m planning the airline system install in my new shop.  It will be
a circle pattern so that it will wrap round the entire room near
ceiling height.  Is anyone familiar with the recommended pitch
or incline recommended for water (condensate) drainage to the
designated vertical drops for line blowdown?
