Twin-screw blowers hold some significant advantages over rotary-lobe blowers, particularly in terms of energy efficiency.
RLR (minus height: 25px; border-width: 32px; )
To improve the efficiency of equipment that uses air blowers for low-volume flows (300 to 5,000 m³/hr), engineers need to look beyond lobe-style blowers. These blowers are widely used in applications such as wastewater aeration, pneumatic conveying, and mixing, and designs have evolved from two to three-lobe designs, mainly to reduce discharge pulsations. But in regards to energy efficiency, lobe blowers have not seen significant improvements over the past 50 years.

Screw compressors, on the other hand, rely on internal compression — as opposed to external compression in lobed blowers — and this dramatically improves efficiency and can produce sizable energy savings. They also run quieter, vibrate less, and are more reliable. Here’s a look at the theoretical and practical details. As the rotors turn, air is drawn through the inlet side and forced out the outlet port against system pressure. There is no change in the volume of the air within the machine.
