Pressure Systems (pressure chambers and compressors) offer the optimal method for creating molds and resin castings that are truly bubble free.
Vacuum Systems (vacuum chambers and vacuum pumps that pull 29 inches of mercury) are used to remove the air from high viscosity materials like silicone rubber before pouring. They are also ideal for vacuum degassing liquid plastics for making bubble free castings.
Versatile Unit for Pressure Casting Liquid Rubber and Liquid Plastics. Recommended Pressure for Pressure Casting is 60 psi. Pressure pot can be pressurized to 80 psi.
12.5" (31.75 cm) diameter opening X 15.25" (38.74 cm) Tall
This easy to use vacuum chamber is tough aluminum and can accommodate up to a 5 gallon pail. The lid is made from shatter resistant acrylic and features a rubber gasket that creates a positive, air tight seal for maximum vacuum. Includes hose. Easy to read gauge let's you know if your vacuum pump is pulling the required 29" of mercury.
