HeliFlow® Series

The Gardner Denver HeliFlow® Series integrates helical tri-lobe rotor technology to help reduce pressure pulsation and operating noise compared with similar-sized straight-lobe blowers. Available models provide airflow up to 4,500 CFM, pressure up to 18 psig, and vacuum up to 17 inHg. 

Why Choose HeliFlow® Twisted Tri-Lobe Technology?

Reduced Pressure Pulsation 

The HeliFlow rotor profile introduces air more gradually throughout the compression cycle, creating a smoother pulse profile than conventional lobe blower designs. Reduced pulsation can help support stable system operation and more consistent airflow delivery. 

 

Quieter Operation 

Discharge pulsation is a primary contributor to blower noise. HeliFlow technology reduces pulsation and can reduce operating noise by approximately 4 to 7 dBA compared with similar-sized straight-lobe blowers.  

HeliFlow Rotors

Robust Industrial Design 

HeliFlow blowers incorporate solid helical tri-lobe rotors, large-diameter shafts, oversized spherical roller bearings, and a one-piece cylinder design to support demanding industrial operating environments. 

 

Designed for Industrial Applications 

HeliFlow technology is used in applications where reduced pulsation, lower operating noise, and reliable blower performance are important selection factors.

Twisted Tri-Lobe vs. Straight Tri-Lobe Blowers

A twisted tri-lobe blower uses a helical rotor profile to create a smoother transfer of air throughout the compression cycle. Compared with similar-sized straight-lobe blowers, HeliFlow technology reduces pressure pulsation and can reduce operating noise by approximately 4 to 7 dBA.

Common Blower Challenges and How Gardner Denver Helps

Excessive Blower Noise

Operating noise can be a concern in facilities where equipment is located near personnel or other critical operations. 

How Gardner Denver Helps 

The HeliFlow helical rotor profile reduces discharge pulsation, which can reduce operating noise by approximately 4 to 7 dBA compared with similar-sized straight-lobe blowers.  

 

Pressure Pulsation and System Vibration

Pressure pulsation can affect overall system stability and contribute to vibration throughout the air handling system. 

How Gardner Denver Helps 

The HeliFlow rotor profile produces a smoother pulse profile than conventional lobe blower designs, helping deliver more consistent airflow. 

 

Matching Technology to the Application 

Industrial applications often have different requirements for airflow, pressure, vacuum, noise levels, and installation conditions. 

How Gardner Denver Helps 

Gardner Denver offers multiple blower technologies and local distributor support to help identify a solution that aligns with application requirements. 

 

Balancing Performance and Noise Reduction 

Facilities often need strong blower performance while minimizing sound levels. 

How Gardner Denver Helps 

Twisted tri-lobe technology helps deliver both reliable airflow and lower operational noise within the same blower platform.  

Frequently Asked Questions

A twisted tri-lobe blower is a positive displacement blower that uses helical three-lobe rotors to move a fixed volume of air or gas through the blower. The helical rotor profile is designed to reduce pressure pulsation compared with conventional lobe designs.
