Vacuum Bagging Supplies for the Amateur and Professional
Vacuum Bagging Pressure Kit
Simple, Effective Kit Runs Off-Shop Compressors

FIG 5541

This complete starter kit will handle repairs and small laminating projects up to 13 square feet
and can be powered by conventional shop air compressors that deliver as little as 60 psi at two
static cubic feet per minute. A key element of the kit is the Venturi vacuum generator developing
more than 10 psi and removing more than one static cubic foot of air per minute. Vacuum pres-
sure makes it possible for an entire schedule of laminate materials to be laid up at one time and
will hold all in place at any angle or attitude. This method provides firm, even clamping pres-
sure over the entire surface area. It also allows rapid cure with a small application of heat.
Vacuumed laminates are uniform, strong and have greater fabric density than friction or gravity-
held laminates. This inexpensive, easy to use kit converts standard shop air to vacuum, making
the vacuum bagging advantages readily available at any repair yard or shop.
