Compressor room Flexibles Compressor room should be : Large for an easy maintenance : Insulated and with a good aeration Flexibles will allow to : Move easily the different machines : Stop vibrations transmission Global piping network design

Main drain Adapted tank Tank will be well adapted : Compressor flow in L/mn

Main drain Adapted tank Tank will be well adapted : Compressor flow in L/mn : 3 = tank volume in liters Main drain and valve : Drain can be at the tank or down the ring inlet : Will eliminate the first condensates before coming in the piping Global piping network design

Isolating valves Bucled main ring Buckled main ring : Better flow at any point

Isolating valves Bucled main ring Buckled main ring : Better flow at any point of the network : Pression is equal along the pipe. Isolating valves : Allow a ring portion isolation for maintenance or modifications Global piping network design

Air drops : Adapted diameter (20 mm is advised) : A good number of

Air drops : Adapted diameter (20 mm is advised) : A good number of drops will avoid too many flexibles on the floor. Global piping network design

1) Flow calculation : CV x 7 = M 3/h KW x 10 =

1) Flow calculation : CV x 7 = M 3/h KW x 10 = M 3/h 2) Pipe lenght : Mesure the maximum lenght between the air inlet and the furthest air drop. 3) Pipe diameter : Line lenght Pipe diameter (mm*) (*) SCFM x 1, 7 = m 3/h Piping network calculation

Wall supports Expansion flexibles 1) Wall supports : Each 3 meters 2) Main line

Wall supports Expansion flexibles 1) Wall supports : Each 3 meters 2) Main line : Don ’t forget expansion flexibles for lenght more than 40 - 50 m 3) Drops : Blow chips before mounting the couplers or others accessories The mounting
