Romanoff Investo-Vac: Combined Vacuum Investment & Casting Station The Romanoff Investo-Vac is the ultimate all-in-one solution for jewelry manufacturers, combining a heavy-duty vacuum table and a high-performance vacuum casting machine into a single, streamlined unit. This compact station allows users to mix investment and cast metal using a single, powerful vacuum source, making it the ideal choice for studios requiring a high-detail workflow in a space-saving footprint. Precision Investing Side The investing section features a spacious 20" x 20" rubber mat working area (expandable up to 25" x 25"). To ensure ease of use and safety, the heavy bell jar is managed by an overhead boom and pulley system with an integrated counterweight, allowing the operator to raise and lower the jar with minimal effort. Bell Jar Dimensions: Approximately 16 1/4" (ID) x 19.5" (OD). Internal Clearance: 7.25" side wall height with a 14" center height. Activation: Vacuuming begins instantly upon pressing the left-sided foot pedal. High-Power Casting Side The casting chamber utilizes a double vacuum chamber system to provide the operator with maximum pull. This design allows the first chamber to build pressure once the pump is active. When the gauge reaches the desired level, a second foot pedal activation opens the mechanical solenoid, delivering a "fast and hard" vacuum pull as metal is gravity-poured into the flask. Integrated Power: Built-in 21 CFM heavy-duty oil vacuum pump. Flask Versatility: Includes adapter spacer rings for standard 4" diameter flasks (up to 10" length). Maximum Capacity: Removing the spacer ring accommodates flasks up to 6" diameter x 9" height.
