Side channel (regenerative) blowers

Side channel blowers (also called ring blowers, regenerative blowers, Vortex blowers and sometimes even turbine blowers) are the first choice for applications requiring large volumes of clean, dry air at low pressures and vacuums.

Side channel blowers serve as air delivery, aeration and vacuum equipment.
The same blower can be used for either vacuum or air delivery applications.

Side channel blowers can also function as vacuum pumps or vacuum blowers. They can generate significantly higher pressures than industrial fans. They are used for both vacuum and pressure applications. A side channel blower generates lower air flow than, for example, centrifugal fans, but delivers over a wide air pressure range. They are a low noise choice (compared to positive displacement blowers).

Factors to consider for blower selection are mainly on the discharge side include outlet pipe diameter and distance, bends and elbows, application (such as medium viscosity (e.g. water) & depth), altitude and air release nozzles or release mechanism.

On the intake side, blocked air filters can affect the blower delivery.

Goorui Series 1 side channel or regenerative blowers
Air blowers from 400 watt to 2200 watt with low and medium pressures.
GHBH series 1 side channel blowers
Goorui Series 3 side channel or regenerative blowers
Two stage blowers like the model 2R3 easily outperform their single stage equivalents, so are the preferred blower in this range.
Goorui Series 3 side channel or regenerative blowers
Goorui Series 5 side channel or regenerative blowers
Here we start getting to the larger blowers, with the 3kw GHBH 2R5 capable of 150m3/h at 200mbar.
Goorui GHBH series 5 side channel blowers
Goorui Series 7 side channel or regenerative blowers
The GHBH 2R7 is a versatile blower with 7 motor options and up to 570 mbar pressure capability. The GHBH AR7 delivers about 350m3/h at 40mbar.
Goorui Series 7 side channel or regenerative blowers
Goorui Series 9 side channel or regenerative blowers
Series 9 blowers are the biggest in this range with up to 20kw motors, 2000m3/h and over 500mbar capacities
Goorui Series 9 side channel or regenerative blowers
Goorui Series GHBG single-stage side channel or regenerative blowers
The GHBG range of two stage blowers incorporate specialized engineering design that enables very high pressure capacities. One is three-stage and capable of 1050 millibar pressure.
Goorui Series GHBG two-stage side channel or regenerative blowers
Goorui Series 2 side channel or regenerative blowers
400 watt and 700 watt single stage and two-stage side channel blowers.
Series 2 side channel blowers
Goorui Series 4 side channel or regenerative blowers
The most popular in this range, the GHBH 2R4, is a two-stage blower with an amazing 420mbar maximum pressure.
Goorui GHBH series 4 side channel blowers
Goorui Series 6 side channel or regenerative blowers
The GHBH AR6 is an interesting blower capable of 230m3h at 100mbar. This blower can work as an air extractor where long pipes require an added pressure capability.
Goorui Series 6 side channel or regenerative blowers
Goorui Series 8 side channel or regenerative blowers
The GHBH series 8 blowers have air capacities between 200 and900 m3/h, with a maximum pressure of 600 mbar (250m3/h)
Goorui Series 8 side channel or regenerative blowers
Goorui Series GHBG single-stage side channel or regenerative blowers
The GHBG range of single stage blowers incorporate specialized engineering design that enables small blowers to have very high pressure capacities.

Two stage versus single stage blowers



The "2R" coded blowers are two-stage blowers. They have two impellers, that enable the blower to maintain pressure over a wider pressure range. A two stage blower is more efficient at higher pressure ranges compared to a similar kilowatt single phase blower. Two-stage regenerative blowers deliver more pressure or vacuum than a single-stage blower of the same kilowatt - at  the generally used upper end of their performance curve. Open the Series 7 range of blowers and compare the performance of the various 2.2kw blowers. Above 150mbar pressure, the 2R7 outperforms every other blower on this chart, so it the the range we tend to stock.
