The Romanoff 1.5 HP Vacuum Machine is the premier high-output system in the series, engineered for the most demanding jewelry manufacturing environments. Refined through years of field-tested experience, this unit offers peak 1.5 HP suction power and outstanding durability. It is the definitive choice for shops that vacuum large batches of invested flasks and require the highest level of vacuum-assisted casting performance available at a reasonable price.

Elite Industrial Engineering

Housed in a totally enclosed cabinet, the 1.5 HP model is built to protect its heavy-duty motor from the high-production rigors of the casting floor.

  • Oversized Aluminum Jiggle Plate: Features a thick, industrial-grade jiggle plate that provides powerful, uniform vibration to ensure every bubble is purged during degassing.
  • High-Accuracy Monitoring: Equipped with an oversized, easy-to-read 0-30" vacuum gauge for absolute precision in atmospheric control.
  • Clear System Visibility: A built-in glass indicator provides a constant view of the oil level and condition, allowing for proactive pump protection.

Built for Maximum Uptime

This 1.5 HP unit is designed for shops that cannot afford downtime, featuring advanced moisture management and simplified maintenance access.

  • Advanced Purge System: Includes a high-performance purge valve to vent moisture and prevent oil contamination, maintaining critical suction power over long shifts.
  • Full-System Access: The removable back cover allows technicians to reach the entire machine interior for rapid oil changes and routine servicing.
  • Massive 1.5 HP Output: Provides the significant torque and air-pull needed to reach deep vacuum levels instantly, even when handling the largest industrial-sized flasks.

The Ultimate Professional Casting Standard

For high-volume production of silver and gold, the Romanoff 1.5 HP machine provides the necessary strength to eliminate porosity and ensure flawless surfaces. By combining a heavy-duty aluminum vibration system with a motor designed for rapid-fire cycles, this machine handles oversized jewelry trees and high-volume ring production with ease. It is a refined workhorse that ensures your investment is perfectly degassed and your vacuum-assisted pours are dense and homogeneous, cycle after cycle.
