How does a regenerative blower work?
The impellers in the G-Series machines are mounted directly on the motor shaft for contact free compression. Maximum operational reliability, even at high differential pressures, is ensured by the arrangement of the bearings outside the compression chamber.Air/gas is taken in through the inlet and enters the side channel. The rotating impeller imparts velocity energy into the air/gas in the direction of rotation. Centrifugal force in the impeller blades accelerates the air/gas outward, increasing pressure.Kinetic energy is imparted with every rotation resulting in further pressure increase. The side channel narrows at the rotor, sweeping air/gas off the impeller blades and discharging it through the outlet silencer where it exits the blower.
The regenerative revolution - Volume flow up to 520 cfm and differential pressure up to 420 in. H₂O. With its significantly expanded range of performance and lower noise levels, the regenerative technology can now be used in completely new fields of application that were previously unimaginable. They deliver 40,000 operating hours between service and are virtually maintenance free.

Industrial bi-lobe, tri-lobe, twisted tri-lobe and helical screw blower technology for pressure and vacuum applications. CompreVac supplies Gardner Denver blowers, complete blower packages, parts and service for Canadian industry.
One manufacturer offering multiple positive displacement blower technologies. CompreVac supplies bare blowers and engineered packages together with application engineering, controls, repair and field service.
Positive displacement blowers move a fixed volume of air or gas through the machine with each rotation. They are widely used where continuous airflow is required against a predictable pressure or vacuum differential.
Gardner Denver offers one of the broadest industrial blower portfolios, including straight bi-lobe, solid tri-lobe, twisted tri-lobe and helical screw designs.
That range allows CompreVac to select blower technology around the actual airflow, pressure, vacuum, efficiency, noise and operating requirements of the system rather than forcing every application into one design.
From traditional roots-style blowers to high-efficiency screw machines, Gardner Denver provides multiple ways to meet industrial air and gas demands.
Bi-lobe, tri-lobe, twisted tri-lobe and helical screw designs are available.
Multiple ranges support positive-pressure and industrial vacuum applications.
Select an individual blower or a complete engineered blower package.
CycloBlower screw technology provides an efficiency-focused alternative to straight-lobe designs.
Choose from complete intelligent packages, traditional lobe blowers, low-pulsation tri-lobe technology or energy-efficient helical screw machines.
The Gardner Denver IQ package combines a positive displacement blower with enclosure, controls and system components in a compact engineered package.
Sutorbilt Legend is Gardner Denver's versatile bi-lobe blower platform, available in numerous sizes and configurations for pressure and vacuum applications.
DuroFlow blowers use solid rotors and heavy-duty construction for demanding industrial environments where durability, mounting flexibility and reliable continuous operation are priorities.
RBS blowers use three-lobe rotor geometry with robust construction and internal feedback porting for efficient, lower-noise positive displacement operation.
TriFlow combines three-lobe impeller geometry, internal feedback porting and heavy-duty construction to provide dependable pressure or vacuum performance with reduced pulsation.
HeliFlow uses solid helical tri-lobe rotors and tuned porting to reduce pressure pulsation, helping lower discharge noise while maintaining heavy-duty positive displacement performance.
CycloBlower uses helical screw compression for higher efficiency, reduced pulsation and quieter operation compared with many conventional straight-lobe blower designs.
CycloBlower H.E. uses a patented 3 × 5 helical screw rotor profile designed around energy efficiency for higher-pressure industrial blower applications.
There is no single positive displacement blower design that is ideal for every application. The correct technology depends on required flow, pressure or vacuum, energy use, noise limits, gas conditions and duty cycle.
Positive displacement blowers are widely used wherever continuous, reliable pressure or vacuum airflow is required.
Diffused aeration, agitation and biological treatment air systems.
Dilute or dense phase transport of powders, pellets and bulk materials.
Conveying and process-air applications in cement and mineral processing.
Clean air delivery for conveying and selected industrial food processes.
Industrial gas movement and process-air applications requiring reliable flow.
Centralized pressure or vacuum systems serving machinery and production equipment.
Gardner Denver provides one of the broadest positive displacement blower portfolios available, allowing the blower technology to be matched to the operating requirements of the process.
CompreVac supplies Gardner Denver bare blowers and complete packages together with application engineering, controls, replacement equipment, parts and field service.
For a new installation, CompreVac can evaluate airflow, pressure or vacuum, duty cycle, piping losses, filtration, noise requirements, energy use and control strategy as part of the complete blower system.
A positive displacement blower moves a defined volume of air or gas through the machine with each rotation. The blower then operates against the pressure differential created by the connected system.
Gardner Denver offers straight bi-lobe, solid tri-lobe, twisted tri-lobe and helical screw blower technologies, as well as complete blower packages.
A bi-lobe blower uses two-lobe rotors, while tri-lobe designs use three-lobe rotors and porting intended to reduce pulsation and improve noise and performance characteristics.
A screw blower uses helical screw rotors to internally compress air before discharge. This can improve efficiency and reduce pulsation compared with traditional straight-lobe blowers in suitable applications.
The Gardner Denver industrial blower portfolio spans small machines through very large units. Published literature lists bi-lobe designs up to approximately 26,000 CFM depending on model and operating conditions.
Traditional lobe blower ranges commonly operate up to about 15 PSI, while CycloBlower screw technology extends the available pressure range. The CycloBlower H.E. literature lists pressure capability up to 36 PSI.
