Anlet CT4-50LE Roots Vacuum Pump with 2 HP Baldor Motor

The Anlet CT4-50LE is a robust Roots-type mechanical booster vacuum pump designed for enhancing the performance of primary vacuum systems in industrial settings. Manufactured by Anlet Co., Ltd., this pump achieves an ultimate pressure of 20 Pa and a design pumping speed of 177 m³/min, making it suitable for applications requiring high throughput and efficient gas evacuation, such as semiconductor processing, chemical vapor deposition, vacuum drying, and metallurgy. It features a water-cooled design to manage heat during operation, ensuring longevity and consistent performance. Paired with a 2 HP Baldor-Reliance Super-E electric motor (1.5 kW output) via a belt drive, it operates at 1653 r/min for the pump, providing reliable power transmission. Key benefits include oil-free operation to prevent contamination, compact footprint for easy integration, and low vibration levels. Compared to similar Roots pumps from competitors like Busch or Leybold, the Anlet model offers superior energy efficiency and easier maintenance due to its simple rotor design. Drawbacks may include the need for a backing pump and external cooling water supply (2 L/min), which could increase overall system costs and complexity. This unit appears new or in excellent condition, ideal for demanding vacuum environments.
