Vac-Reg Vacuum Regulator

Vac-Reg has been designed to provide accurate, controlled vacuum for parts that use honeycomb core. Vac-Reg is a small in-line unit that is easy to use. Each part in the shop can be independently regulated using Vac-Reg. It uses standard 1/4 inch male NPT fittings and will accept AQD 500TF, Airlock 450TF & 550TF quick disconnect fittings.

Core movement is a serious problem in the manufacture of composite parts. Full vacuum, removing all the air in the core cells after the lay-up is a part of the problem. The larger the pressure difference between the air in the core and the outside atmosphere, the greater the chance of core movement. Controlling the amount of vacuum inside the core cells is key to preventing core movement. Major aerospace companies limit the vacuum over core assemblies to 0,34 bar, prior to cure. This eliminates core movement, adhesive "pillowing" and core crush possibilities. Vac-Reg can also be used as a means of regulating vacuum in the resin infusion application where full vacuum is not desirable with some resin systems such as polyesters.

Note: Vac-Reg is an inexpensive reference gauge for shop use only.
