Teams selecting blower packages in Wastewater Treatment and Food & Beverage often face the same issue: airflow, pressure, vacuum, noise, controls, and enclosure details are scattered across many documents. Early decisions slow down. Layout planning drifts. The Blower Packages Comparison Chart brings the IQ, IQ‑RB, and GD IQ‑HE families into one view so you can compare operating ranges and package characteristics without digging through multiple datasheets. It helps you focus on the right family before spending time on performance curves and detailed engineering. 

Three Gardner Denver blower packages displayed side by side: the IQ Package on the left, the IQ‑RB Package in the center, and the GD IQ‑HE Package on the right, each shown as full enclosure units.

What This Comparison Chart Helps You Do

Use the infographic to quickly evaluate three core package families from Gardner Denver and understand how each supports specific airflow, pressure, and vacuum requirements. Each family covers different operating envelopes and duty styles. The chart highlights these distinctions so you can narrow your options early. 

Why Selection Can Be Challenging

Across both Wastewater Treatment and Food and Beverage industries, teams often face the same three challenges: 

  • Scattered specifications — airflow, pressure, vacuum ranges, sound, serviceability, and controls are rarely in one place.
  • Overlapping options — multiple blower package families can meet similar operating points, but with different energy profiles, enclosure designs or maintenance requirements.
  • Decision delays — uncertain selection leads to longer project cycles, delayed layouts, and slower quoting.

The blower packages comparison chart simplifies all of this, helping you quickly identify which Gardner Denver blower family best aligns with your pressure, flow, duty cycle, space and sound requirements. 

How The IQ Blower Package Families Differ

IQ Package: compact, quiet and built for controlled environments 

The IQ package fits applications that need a compact enclosure, low noise, and straightforward control. Operations that run equipment near occupied areas gain the most from its sound profile and organized layout. 

Capabilities: 

  • Airflow up to about 1,500 cfm
  • Pressure up to 15 psig
  • Vacuum up to 17 inHg
  • Sound levels often near 60–65 dBA depending on setup

Where it applies 

  • Packaging lines and process air in Food & Beverage
  • Backwash systems, polishing loops, or side‑stream aeration in small wastewater processes
  • General industrial air and vacuum where space is limited

Why teams pick Gardner Denver the IQ Blower Package 

  • Front‑panel access simplifies routine tasks
  • Smart Controller covers key monitoring functions
  • Useful in noise‑sensitive or space‑restricted locations

IQ‑RB Package: Higher airflow for low-pressure and vacuum services

IQ‑RB extends into higher flow ranges with a tri‑lobe RBS design suited for steady, continuous duty. It offers predictable performance where systems require stable air supply and low maintenance interruptions. 

Capabilities: 

  • Airflow up to about 5,500 cfm
  • Pressure up to 15 psig
  • Vacuum up to 15 inHg
  • Fixed‑speed operation optimized for consistent output

Where it applies 

  • Aeration, EQ basins, and DO‑focused processes in wastewater systems
  • Low‑pressure pneumatic conveying in Food & Beverage, including grains, sugar, or additives
  • Centralized vacuum systems with steady demand

Why teams choose IQ‑RB: 

  • Dual‑splash lubrication and long‑life bearings support long service intervals
  • Enclosure and controls layout support predictable operation
  • Suited for environments where durability and stable output matter most

Gardner Denver IQ‑HE Package: Higher pressure and reduced energy consumption

The Gardner Denver IQ‑HE package supports higher discharge pressures with a screw‑type rotor profile aimed at reducing energy use during long‑duration operation. Facilities that manage significant blower energy spend often start here. 

Capabilities: 

  • Airflow up to about 5,625 cfm
  • Pressure up to 36 psig
  • Screw rotor profile focused on energy performance
  • AirSmart 2 Controller for advanced monitoring and control

Where it applies 

  • Wastewater aeration systems running at higher pressures
  • Dense‑phase or long‑distance pneumatic conveying in Food & Beverage
  • Process air applications that require tighter control and frequent demand changes

Why teams choose IQ‑HE: 

  • Energy‑focused design supports lower long‑term operating cost
  • Higher pressure range offers greater design flexibility
  • Strong match for plants using VFD or variable‑flow strategies

How to use the Blower Packages Comparison Chart in Project Planning

Use the chart as a first screen before detailed sizing: 

  1. Identify airflow, pressure or vacuum requirements, duty cycle, sound considerations, and available space.
  2. Compare your duty with the operating ranges in the chart.
  3. Match your application type with the package characteristics: 
    1. Wastewater Treatment: aeration pressure, DO stability, enclosure, control strategy
    2. Food & Beverage: sound in packaging zones, material wear in conveying lines, hygiene considerations
  4. Narrow to one or two package families.
  5. Move into datasheets and performance curves for exact sizing and selection.

This sequence helps teams reduce rework, shorten planning cycles, and avoid spec drift. 

Who the Gardner Denver Blower Package Comparison Chart Helps Most

  • Engineers handling early design work for wastewater aeration or Food & Beverage process air
  • Maintenance teams standardizing blower equipment across multiple sites
  • OEMs and system integrators developing packaged systems for aeration or conveying
  • Sourcing teams comparing package families from the same supplier
