West System Vacuum Bagging Materials 885 6 Venturi Generator . Vacuum bagging is a clamping system used for laminating a wide range of fabrics, core materials and veneers. It offers many advantages over conventional clamping. For repairs and composite construction, it uses atmospheric pressure to deliver firm even clamping pressure over the entire surface area, regardless of the type or quantity of material being laminated. By laminating over simple molds, composites can be molded into a wide range of functional shapes. 879 Release Fabric Economical Release Fabric is a tough, finely woven nylon fabric treated with a release agent. It is used to separate the absorber, breather and vacuum bag from the laminate in vacuum bagging operations. Excess epoxy bleeds through and is peeled from the cured laminate along with the Release Fabric. It's also used in hand lay up applications to allow more squeegee pressure and protect the lay up from contamination. Peels easily and leaves a smooth textured surface, ready for bonding or finishing. Not recommended for post cure temperatures over 120F 49C. Available in 60 wide x 2 yd., and 10 yd. rolls also in 60 x 9 sheets. 881 Breather Fabric Breather Fabric is a lightweight, polyester blanket that provides excellent air passage within the vacuum envelope while it absorbs excess epoxy. Available in 45 wide x 2.7 yd., and 10 yd. rolls. 882 Vacuum Bag Film Clear, heat stabilized, modified nylon resin film. Can be used at temperatures up to 350F 176C for typical composite cure cycle times. A tough, stretchable film for high vacuum pressures. Available in 60 wide x 2 yd., and 20 yd. rolls. 883 Vacuum Bag Sealant Mastic tape sealant for airtight seals between vacuum bags and molds. Easy to work around difficult angles, patching small leaks in the vacuum system. Available in 12 wide x 25' roll. 885 Vacuum Bagging Kit A complete starter kit for room temperature repairs and small laminating projects up to 13 square feet. The kit includes 32 page manual on ''Advanced Vacuum Bagging Techniques.'' Instructions. Venturi vacuum generator. Vacuum cups. 14'' I.D. vacuum tubing 10'. Vacuum gauge. Junction ''T'' barbs 2. Release fabric 15 sq. ft.. Breather fabric 15 sq. ft.. Vacuum bag film 15 sq. ft.. Vacuum bag sealant 25 sq. ft.. The venturi generator develops over 20 inches Hg mercury of vacuum 10 psi. It is designed to run off of conventional shop air compressors delivering at least 65 psi at 3.5 SCFM. At 0 inches Hg it will evacuate 2.2 SCFM. The operating range is 40 psi 100 psi.
