Let’s take a look at our Hybrid Blowers. Hybrid refers to two different types of positive displacement (PD) blowers. Those two types are the screw impeller and the twisted tri-lobe impeller PD blowers. The purpose of this tech memo is to illustrate the differences and define the proper application range of each.
The best feature of both types of blowers is that they do not surge.

This memo compares aeration basin options for WWTPs up to 2.0 MGD, noting that while SBRs were once cost-effective, reduced supplier competition and higher lifecycle costs now make conventional treatment more favorable.
This memo compares APG NX and ABS HST turbo blowers, highlighting APG’s superior efficiency (7–11% higher), U.S.-based manufacturing and service, and simpler installation. In contrast, ABS units require more piping and HVAC runs, adding hidden construction costs and requiring taller ceiling clearances.
