Leybold developed the TRIVAC L, a new model of the two-stage rotary vane vacuum pump designed to generate pressures in the rough and fine vacuum range in industrial and research applications. This model offers a balance of performance and efficiency, providing an outlet that is suitable for both vertical and horizontal alignment, making it ideal for use in analytics, pharmaceuticals, and coating carrier materials for semiconductor or solar technology. In production environments with high humidity, the patented three-stage gas ballast improves water vapor tolerance. Available in different pumping speed classes, the pump is equipped with a standard drain valve and a sight glass for monitoring oil level.
