Find the Positive Displacement Blower for Your Flow, Pressure, Efficiency, and Process Requirements
If your blower is undersized, inefficient, noisy, or difficult to maintain, the effects can show up quickly in process performance and operating cost.
Lewis Systems helps industrial facilities compare positive displacement blower technologies based on the conditions that matter most: required airflow, pressure or vacuum, duty cycle, energy use, noise, available space, and maintenance requirements.
Whether you are replacing an aging blower, adding capacity, or specifying equipment for a new process, our team can help you identify the Gardner Denver solution that best fits the application.
What Matters When Selecting a Positive Displacement Blower?
The best blower is not always the model with the highest airflow or pressure.
Lewis Systems helps evaluate the factors that affect performance and total operating cost, including:
Flow & Pressure Requirements
How much airflow does the process require, and at what pressure or vacuum level?
Duty Cycle
Will the blower run intermittently or continuously?
Energy Use
For continuously operating equipment, blower efficiency can have a significant impact on long-term operating costs.
Noise & Pulsation
Applications near operators, occupied spaces, or sensitive downstream equipment may benefit from technologies designed to reduce pulsation and sound.
Installation & Footprint
Available floor space, mounting orientation, piping, and access for service can influence the best configuration.
Maintenance & Reliability
Lubrication design, bearing life, service intervals, and access to replacement parts should all be considered before equipment is selected.
