Data Sheet VAC-REG
Vacuum regulator
Hi DESCRIPTION
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 5O0TF, Airlock 450TF & S50TF 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 10 in. Hg (34 kPa), prior to cure. This helps eliminate core movement and core crush. 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.
@ BENEFITS
+ Dial in the right vacuum level for your application.
+ Small and portable, Vac-Reg can be easily carried in tool bags.
+ Simple gauge provides indication of vacuum level and highlights any leaks present.
