what is ring blower ？
Introduction to Blowers

A ring blower (also named Side Channel Blower or Regenerative Blower) provides maximum pressure upto 60mbar to 1050 mbar( 6Kpa to 105 Kpa) , maximum vacuum 60mbar-730mbar (6Kpa to 73 Kpa), maximum airflow 50-2350 m3/h and maximum motor power 0.2KW to 25 KW(34 HP),

ring blower is widely used in the fileds of Plastic pellet conveying(or plastic injection molding machine particles feeder), vacuum lifting. Wastewater treatment aeration, food processing machine, agriculture,foam molding, pneumatic conveying system, printing machine,packing machine,textile. when the pressure or the vacuum is too excessive for centrifugal ventilators or when a compact construction type is required. Ring(Side) channel blowers will additionally produce much less noise than centrifugal or radial ventilators with equal pressure, once the right measures are taken.

What is the difference between the Ring Blowers / Side Channel Blowers / Regenerative Blowers...?

Actually, the names stand for the same blower, just different description in different industries/ areas.

Ring Blowers / Regenerative Ring Blowers / Side Channel Blowers / Regenerative Blowers / Turbine Blowers / Vortex Blowers / Vacuum Blowers / Medium Pressure Blowers /High Pressure Blowers / High Vacuum Blower / Ring Compressor / Lateral Channel Blowers refer to the exact same blowers.

Working Duty: S1 Duty

No Maintainance, only change bearings when needed.

Differences between Single stage , double stage, three stage regenerative / Ring/ Side Channel Blowers

Classification of regenerative /Ring/Side Channel Blowers:

The regenerative /Ring/Side Channel Blowers can be divided into single impeller(single stage), doube impellers(double stage), and three impellers(three stage) . As the name suggests, it is defined by the number of built -in impeller. At the same power:

Pressure: Single stage Blowers< double stage Blowers < three stage Blowers

AirFlow: Single stage Blowers< double stage Blowers < three stage Blowers

Weight and volume: Single stage Blowers< double stage Blowers < three stage Blowers

Price: Single stage Blowers< double stage Blowers < three stage Blowers

Single stage Blowers means that there is only one impeller inside, the outlet and the inlet of single stage blower are generally parallel, and the amount of air volume is smaller than Doubl Stage Blowers, and can meet the work on food machinery, pharmaceutical machinery, material conveyor, printing machinery, industrial vacuum equipment, woodworking machinery, plastic machinery, textile machinery and other equipment;

Features of double stage ring blower and single stage ring blower:

1. Stable operation and easy installation (small models need to be placed properly when running, the vibration is very small, generally no need to install anti-vibration devices, easy to install);

2. Resistant to load changes and stable air volume (for example, if the pressure of the sewage treatment aeration tank changes, the load will change, but the air volume will change little with the pressure change).

3. Equipped with an air chamber to diffuse air smoothly (all models are equipped with an air chamber to prevent air pulsation and diffuse air smoothly);

4. The material is strong, the structure is ingenious, and the performance is high (all the ring blowers are made of materials, the structure is ingenious, durable, high performance, and there are few failures in long-term use).

How does Ring Blower work?
Working Principle of Regenerative Ring Blowers/ side channel blower.

Ring blowers may be the least understood technology in the field of air handling equipment today, but when system parameters fall within the ring blower range, it may be the most economical way to generate pressure or vacuum.
Side Channel Blower, Turbine Blower, Vortex Blowers, Ring Compressor, Vacuum Blower,High Pressure Blower, High pressure /Vacuum Blower, Lateral Channel Blower, Etc.

A flow rate of 2050 m3/h , maximum vacuum of 730 mbar,and maximum pressure of 1040 mbar are all provided by the maximum capacity currently being manufactured.
The RING BLOWER's basic design features a balanced radial impeller that is directly motor-driven, housed in a housing with tight tolerances, supported by bearings, and sealed with seals.
Most commonly, pressure diecast aluminum alloy impeller and housings are in demand because they offer durable yet lightweight machinery. The majority of inlet and outlet ports have threads and a silencer. The impellers and housings for multiple stage units are all different.
Approximately 2900 RPM is the impeller's normal speed. Due to its fundamental design, a RING BLOWER has many advantages for engineers, one of which is the absence of maintenance and monitoring requirements.

As the only moving component, the impeller is "wear-free" because it never makes contact with the housing channels. The only wearable components are self-lubricating bearings. BLOWERS OF RINGS RING BLOWERS is without oil and simple intake/exhaust valving structure and easy operation .
Additionally, the majority of blower brands have dynamically balanced impellers and can be mounted in any plane, resulting in minimal vibration. Discharge air from a "non-positive displacement" compressor/vacuum pump is clean and pulsation-free, which is a crucial factor, especially for plant controls or instrumentation use.

The main features of the Rexblower RING BLOWER are :

1. High pressure, large air volume, low noise, light weight
2. Aluminum alloy material, greatly reducing the weight and achieving the purpose of light weight
3. Fully closed external fan type aluminum frame motor, special shaft design, suitable for long-term use
4. Special blade design, high pressure, large air volume, low noise and long life
5. Special air volume adjustment damper, high air volume control stability, easy operation
6. Complete range of styles, large inventory, fast delivery

Why choose Regenerative Ring Blowers/ side channel blower?
The difference between the Ring Blowers and the centrifugal blower

The difference between the Regenerative Ring Blower and the centrifugal blower is that the impeller consists of dozens of blades, and it is similar to the impeller of a huge gas turbine. The air in the middle of the impeller blades is affected by the centrifugal force and moves to the edge of the impeller, where the air enters the annular cavity of the pump body and recirculates in the same way from the starting point of the blades. The circulating air flow generated by the rotation of the impeller also leaves the air pump for use with extremely high energy.

Quickly understand the high-pressure ring Blower

High-pressure ring Blower, also known as high-pressure regenerative blower and high-pressure side channel blowers, are widely used in industry and agriculture, covering infrastructure, environmental protection, automobile industry, electroplating industry, textile, food machinery, and packaging industries.

Main Feature

The high-pressure vortex ring Blower (ring Blower, regenerative blower, side channel blower) is a new type of air source generating equipment. It uses high-strength, fatigue-resistant high-quality aluminum alloy as the main material. It has the characteristics of compact structure, small size and light weight. The high-pressure vortex fan adopts a special motor directly Coupled type, without any speed change mechanism, because of its simple structure and direct transmission form, it not only has low noise, low energy consumption, but also has the advantages of stable performance and convenient maintenance, and the air source delivered is water-free, oil-free, and warm. It is unmatched by other air source generating equipment. In general, high-pressure Blower have the following characteristics:
1. It has dual functions of blowing and sucking, one machine can be used for both suction and blowing;
2. Running with less oil or no oil, the output air is clean;
3. Compared with centrifugal Blower and medium pressure Blower, the pressure is much higher, often more than ten times that of centrifugal Blower;
4. The pump body is one-piece die-casting, and the anti-shock mounting feet are used, which is easy to install and easy to use;
5. Compared with similar Blower, its operating noise is lower, just like the ultra-quiet high-pressure ring Blower launched by Rexblower ring Blower:
6. Maintenance-free use; its wearing parts are only two bearings, basically no maintenance is required within the warranty period;
7. The mechanical wear of the high-pressure ring Blower is very small, because there are no other mechanical contact parts except the bearing, so the service life is of course very long, and it is no problem to use it for 3 to 5 years under normal circumstances;
8. Easy to install and easy to use!
