Frequently Asked Questions
Q
What is the vacuum extraction rate range available in the LGB series?
The LGB series offers a wide range of vacuum extraction rates, from 10 L/S (LGB-10) up to 400 L/S (LGB-400), making it suitable for both small-scale and large industrial vacuum applications.
Q
Do all LGB models operate at the same speed?
Yes, all models in the LGB series operate at a consistent speed of 2900 rpm, ensuring stable and reliable vacuum performance across the entire product range.
Q
Which LGB models require cooling water, and how much is needed?
Models LGB-10, LGB-15, and LGB-20 do not require cooling water (0 L/min). Starting from LGB-50, cooling water is required, ranging from 8 L/min for the LGB-50 up to 30 L/min for the LGB-400.
Q
What is the limiting pressure for all LGB series models?
All LGB series models share a uniform limiting pressure of 5 Pa, which indicates a high level of vacuum performance suitable for demanding industrial and scientific processes.
Q
How do I select the right LGB model for my application?
Selecting the right model depends primarily on your required vacuum extraction rate and available power supply. For smaller systems with lower power budgets, models like LGB-10 to LGB-20 (1.1–2.2 KW) are ideal. For high-throughput industrial use, LGB-300 or LGB-400 (30–37 KW) are recommended.
Q
Is the LGB series suitable for continuous operation?
Yes, the LGB series is engineered for continuous and stable operation. The consistent speed of 2900 rpm and the cooling water system (on larger models) help maintain optimal operating temperatures for long-term, uninterrupted use.
