1. What the C-Series Multistage Blower Is All AboutC-Series multistage centrifugal blowers are designed for industries that need strong, steady, and clean airflow. Instead of using just one impeller, these blowers use several stages to build pressure step by step. This makes the air output more powe
1. What a Vacuum Gauge Really Does1.1 Why Vacuum Gauges MatterA vacuum gauge is a small but very important tool. Its job is to show the pressure or vacuum level inside a system. By giving clear and real-time readings, it helps prevent equipment damage, production failures, and safety risks. If the p

1. What Makes the 2BV Series Special1.1 Strong Performance with Gas and SteamThe 2BV water ring vacuum pumps are designed to handle gas and steam with ease. They can reach a vacuum level of up to 97%. And when transformer oil is used as the working liquid, the vacuum level can go even higher—up to
1. What the NSRH Roots Blower Is All AboutThe NSRH Roots blower is a strong, steady, and reliable machine used to move air in many industries. It delivers a constant air flow, works for long hours, and stays stable even when system pressure changes. Because of its strong structure and simple working
1. What the 2BX Relief Valve Is All AboutThe 2BX series relief valve is a simple but very important part used with side channel blowers. Its main job is to keep the system safe by releasing extra pressure when things get too high. Because it works with both pressure and vacuum systems, it fits many
Arotary bloweris a small but powerful machine that moves air or gas by using a spinning rotor and sliding vanes. You’ll often find it in places where steady airflow, low noise, and compact size are important. Compared with other blowers, a rotary blower is simple, efficient, and easy to
1. Introduction to Pneumatic ConveyingPneumatic conveying is a modern material-handling technology that uses airflow within a pipeline to transport bulk solid materials from one location to another. It has become an essential solution in many processing and manufacturing industries, especially where
