compressed air drip leg 2

[kszyho100]

Hi
I just wonder if it is necessary to design drip leg for water residues before air preparation block (filter/regulator w manual drain + lubricator).
Compressor is equipped with a refigerant air dryer. All piplines are in heated rooms.

The refrigerated dryer would lower the dew point down to ~40 F (likely highest) and since you are in a heated room, the temperature should not go below that - so no condensation should form inside the piping.

No drip leg.

Yes drip leg.

The dryer will work most of the time. The drip leg is useful for upset conditions in the dryer and for removing sediment or other contamination.

The cost of having to install a drip leg later on if if the equipment malfunctions or performance degrades is alot greater than installing it initially.

Yup.... stick a drip leg at the far end of the system. Put a blowdown valve at the bottom

Its cheap and effective...
