Hosco has provided Static wire air hoses to provide added layers of ground protection for spray guns or other air powered devices. In addition, we have added grounded hoses using conductive layers of thermoplastic hoses to accomplish this as well and increase flexibility, weight and other ergonomic factors. Hosco supplies 5/16” or 8mm ID hoses most commonly but has other sizes available as special order. X1 is the strongest most robust hose with a continuous static wire, X2 is also a continuous static wire using lighter weight thermoplastic, and there X4 hose configurations using graphite impregnation to insure static level grounding. Grounding of items in the spray zone is critically important and should consist of three layers of safety, which are: the part being sprayed should be grounded, the person or spray station should be grounded, and the spray device should be grounded. Grounding the spray device can and should be done in three ways, which are thru the spray gun, thru the spray operator, and thru the electrostatic power supply and cable if applied electrostatically.
