Roots and ring blowers

We supply a range of roots and ring blowers. For most aquaculture applications a ring blower is sufficient, but where higher volumes and or pressures are needed, we have roots blowers to service this function.

Examples of ring blower applications:

• Medium sized shrimp/fish hatchery
• Printing
• Biogas boosting
• Painting
• Dust collecting

Examples of roots blower applications:

• Large shrimp hatchery
• Pneumatic conveying system (food, mining etc.)
• Combustion air supply for cement kiln
• Waste water treatment
• Biogas boosting
• Various industrial factory applications

Silent 220 volt ring blower

Ring blowers can perform both an air delivery and vacuum function. For both, there is a maximum volume and a maximum pressure, so you need to select your blower knowing your usage as pressure and volume needs to fall within these two parameters. This type of blower is also referred to by other names such as Regenerative blower, Ring Compressor, Side channel blower or Vortex Blower.

Here, the one blower on the red line deliver a maximum volume of 80 m³ per hour and a maximum pressure of just over 120 mbar. At 120 mbar, it will deliver 20 m³/hr. Therefore, first calculate the depth (pressure) you will work at and then determine the air volume that you require.

A range of capacities and 220 volt and 3 phase, 380 volt models are available. These blowers require no maintenance and do not use oil. Deliveries from 0.6 m³/min to 25m³/min are available. In terms of kilowatts these range from 0.15 Kw to 15 Kw. Pressure delivery as mm H₂0 (milliliters of water head) ranges from 500 mm to 3,500mm. Current amperage ranges from 1.2 to 47 Amp.

Applications and advantages

Ring blowers are suitable for all those applications requiring considerably higher pressures than that which can be achieved using centrifugal fans. Side channel exhausters are used in all those applications requiring an operating vacuum higher than the one achievable by a fan, but not as high as to require the use of a vacuum pump. The rotating parts are not in contact with the casing. There is therefore no friction during operation and thus no internal lubrication is necessary. The gas moving through the machine therefore remains uncontaminated and completely oil-free. The main feature are:

• easy installation
• low noise level
• no vibration and therefore complete dynamic stability
• minimal maintenance
• Simple Maintenance
• 100% Oil Free Air
• Suitable to environment protection
• Small size
