Side channel blower (regenerative blower) installation


For electrical installation, ensure that a qualified electrician does the wiring connections and electrical box, as this requires a full knowledge of single phase, 3-phase and motor connections. Air plumbing may need a qualified plumber for some applications.

Blower installation - general procedure

We have some video links below

In relation to this video, many water aeration applications do not use a pressure release valves or gauge as illustrated. This is however the professional and perfect way to install a blower. The blower is cooled by its own airflow, so the volume of air released must be within the range of the blower pressure versus air flow curve.

The air intake filter prevent large items like stones, insects or lizards getting sucked in and damaging the impellor. Once the fan impellor is damaged (e.g.broken vane), the unit becomes unbalanced.

If in a highly dusty environment, then a different filter to the standard MF filter is needed. A filter morel like a generator or tractor filter needs to be installed. For example in a coal mine, coal tar type grease can collect around the impellor is a good, fine particle filter is not used.

General installation for hot tub or Jacuzzi

Instead of non-return valves and large bends as in this video, place the blower above the water level. This is to prevent back siphoning of water into the blower when there is a power failure or the blower is switched off. Water flowing into the blower can damage the blower. Non-return valves can fail and leak, so ae not the safest solution.

The blower diameter for the delivery line depends on the size of the blower in use the distance to the point of use and is of a diameter to minimize friction losses in the pipe line.

With three-phase blowers the motor can run backwards if the phases are incorrect. Switch the two outside phases to reverse the blower direction. As stated, a qualified electrician should do the installation for the blower warranty to remain valid.

Main Goorui air blower applications

Ecotao will advise on and select an air blower according to your specific need and application.

Aquaculture, aquaponics, hydroponics
Aquaculture aeration
Aquaculture aeration
Positive displacement blowers
These blowers have a capacity for very high volumes and pressures up to 1 Bar.
positive dislpacement blower
12 volt and battery-powered blowers
Direct current blowers for battery and solar applications, ranging from 1.5 volt to 48 volt. These are often used in solar applications.
Diaphragm compressor blower, DC, 12 volt
Dental suction of water vapours
Venting of moisture and fine water particles
Dental suction
Small tank blowers
Diaphragm-type compressor blowers delivery relatively good pressures at low volumes suited to smaller tanks and systems with flow requirements between 10 and 200 liters per minute.
LP100 Waterfall diaphragm blower
Screw compressors and high pressure blowers
Some applications require air delivery at pressures over 1 Bar. These require equipment such as screw compressors for high volume, high pressure air delivery.
