IQ‑RB Product Brochure

Customers looking for predictable air performance, reduced equipment footprint, and simplified service usually land on the same question: which package checks all three boxes without inflating project costs? The IQ‑RB brochure answers that directly.

Access performance curves, dimensional drawings, maintenance features and model specifications across all five IQ‑RB frames.

Overview: What the IQ‑RB Series Delivers

The IQ‑RB Series is built for high efficiency and low noise in a footprint engineered to free up floor space. Capacity reaches 6000 CFM, with pressure capability to 15 PSI and vacuum to 15 inHg. Every model in the line is built on the same idea: strong airflow without service complexity. 

The package uses the Gardner Denver RBS tri‑lobe blower, inverter‑duty motors, sealed mechanical gauges, removable access panels, and a patented noise‑reduction enclosure. Front‑facing serviceability cuts downtime and makes the unit approachable for operators of all levels.

Key Features

Performance

  • Tri‑lobe RBS blower for stable flow at high speed
  • Fixed‑speed or VFD‑ready variable‑speed configurations
  • Dual splash lubrication on drive and gear ends for long service life
  • Helical timing gears for smoother, quieter operation
  • High‑strength shafts and reinforced bearings designed for 100,000‑hour life under severe duty 

 

Noise Reduction

  • Double‑insulated sound enclosure
  • Tunable inlet filter/silencer
  • Discharge silencer and tri‑lobe pulsation reduction
  • Typical operating sound levels under 80 dBA across most models 

 

Maintenance

  • All service tasks accessible from the front
  • Quick oil changes with front‑mounted fill and drain hoses
  • Visible oil level gauges that can be checked while running
  • Automatic belt tensioning and streamlined belt replacements
  • Mechanical gauges for filter restriction, discharge pressure and temperature 

 

Compact Construction

  • Significantly reduced package dimensions
  • Side‑by‑side installation capability
  • Single‑piece cast‑iron cylinder for thermal stability and internal clearance retention
  • Ribbed impeller case for heat dissipation 

Model Range

Five frames support airflow needs from 150 to 6000 CFM, with horsepower ranges from 3 HP up to 600 HP. Detailed performance data for each model, including pressure and vacuum ratings, motor BHP, and noise levels, are provided in the brochure.  

Technical Resources Included in the Brochure

The downloadable asset includes: 

  • Full performance tables (pressure and vacuum) across all models
  • Dimensional drawings for frames 1 through 5
  • RPM vs. sound level charts
  • Component diagrams and enclosure details
  • Motor sizing information
  • Operating conditions used for performance ratings (14.7 psi, 68°F, 36% RH)

Frequently Asked Questions

The package combines double noise‑insulated panels, a patented tunable inlet filter/silencer, helical gears, and a tri‑lobe rotor design that reduces pulsations at the source. These elements collectively lower radiated sound without enlarging the enclosure.
