Are you planning to upgrade your vacuum system or purchase a new blower for your machinery? Choosing the right side channel blower (also known as a vortex vacuum pump or ring blower) is critical.
A mismatched blower can lead to poor machine performance, high energy consumption, or even equipment failure. With so many models available—single stage, double stage, high pressure—how do you make the right choice?
At Jinan Golden Bridge, we have helped hundreds of clients worldwide optimize their air systems. In this guide, we break down the top 5 factors you must consider to select the perfect model for your application.
The most important rule in selecting a blower is understanding the relationship between Pressure (Vacuum) and Airflow (Volume). Generally, these two parameters work inversely:
High Airflow applications: If you need to move a lot of air (e.g., for aquaculture aeration or drying systems), prioritize airflow volume (m³/h).
High Pressure/Vacuum applications: If you need strong suction or holding force (e.g., for CNC router hold-down or pneumatic conveying), prioritize pressure (kPa/mbar).
Pro Tip: Don’t just look at the maximum rating. Look at the performance curve. The operating point should be in the middle of the curve, not at the extreme limit.
One of the most common questions we get is: "What is the difference between a single stage and a double stage blower?"
Single Stage Blowers: Have one impeller. They generate high airflow but lower pressure. They are compact and cost-effective for general ventilation and aeration.
Double Stage Blowers: Have two impellers. The air is compressed twice, resulting in much higher pressure (almost double that of a single stage) but with slightly lower airflow.
Rule of Thumb: If your required pressure exceeds 20-30 kPa, a double-stage blower is usually the safer and more efficient choice.
Are you buying this machine for local use, or will you export your equipment to the USA, Europe, or Southeast Asia?
Frequency: China and Europe use 50Hz, while North America and parts of South America use 60Hz. A blower running on 60Hz will spin faster and offer higher performance than on 50Hz.
Voltage: Ensure the blower supports the local voltage stability.
At Jinan Golden Bridge, our blowers feature wide-voltage and dual-frequency motors. This means the same unit can often be used globally, making inventory management easier for machine builders.
Where will the pump be installed? The environment dictates which accessories you need to protect your investment.
Dust & Debris: If the air contains dust (e.g., in a wood workshop or factory), you must install an Air Filter at the inlet. Dust is the #1 killer of vortex pumps.
Noise Sensitivity: While side channel blowers are quieter than Roots blowers, they still generate noise. If installed indoors (like in a hospital or lab), consider adding an external Silencer.

Finally, look at the construction details. Not all blowers are built the same. A high-quality blower ensures 24/7 continuous operation without overheating. Key features to look for (which are standard in our products):
100% Copper Wire Motors: Ensures stable conductivity and heat resistance.
Bearings: High-quality bearings extend the lifespan of the pump significantly.
Die-cast Aluminum Housing: Provides excellent heat dissipation and corrosion resistance while keeping the unit lightweight.
Selecting the right side channel blower doesn't have to be complicated. By focusing on your pressure/flow requirements and considering the installation environment, you can ensure long-term efficiency.
