What is the S and A Logo?

he main shape of our logo is based on a cross section of a bilobe impeller; the primary functioning component of a blower.
The impellers (two in total, also known as rotors) rotate within an air tight casing: this motion causes air to be displaced via the inlet/outlet ports.

There are other impeller profiles in existence, such as trilobe (3 lobe) impellers but we thought that the bilobe would better suit the design.
