airlines and couplings

[brightspark]

using pressurised sandblast pots take a large quantity of air to run .using inadiquate airlines filters and couplings to the pot reduce the cfm delivered if u are using pcl couplings the bore on these are only 3/16th use the next size up which is 9/32 a lot larger .then u can use 1/2inch delivery hose. using the gear through 2 water seperators one on comp tank and one on the pot further reduces cfm the best way is take a supply of other end of tank with the larger coupling direct to pot using only one water seperator on the pot its self .doing a few tests i ran the pot using a 3mm jet the comp kept pressure at 90 psi constant using small fitttings and seperators .at the nozzle they didnt seem to be a lot of power. lack of cfm not pressure .on increasing the size of fittings pipes and only one water trap. i retried the setup the pressure decreased from 90psi to 82 psi but the volume well increased by a large amount proving that the restricted pipes were the cause



[/ATTACH][/ATTACH] here are a few fittings shown in photos ive set comp at 120psi max so i dont use regulator in case anyone notices hope this helps anyone having problems. forgive my composition

Good stuff. I've just hooked up my two comps but mainly have the 1/4" PCL, and some of the Euro ones that are a bit bigger. We'll see how that goes, looking to up them all to the Euros at least but will try with what I've got for now.

short strait pipes larger bore double fitting on the end one larger than other so u have both sizes. i use a smaller 4 ft long tail plugged in with pcl fittings on for smaller things easier to pull and move about
