Low-Pressure Blowers

Commercial, industrial, and building operations often rely on compressors to generate consistent and controllable air flows. Low-pressure blowers generate low-pressure air for applications that don’t operate at high pressures, such as fermentation, aeration, and pneumatics. These blowers work by creating a vacuum with a rotor or impeller. Once air rushes into the vacuum, centrifugal forces act on the air to increase the stream’s speed and volume. The airflow is targeted and discharged at a slightly elevated but still low-pressure level. At Buykaeser, we provide our clients with high-quality, low-pressure blowers that provide consistent streams of compressed air. Learn more about the applications of low-pressure blowers, their advantages and disadvantages, and how to find the right unit for your applications.

Applications of Low-Pressure Blowers

Low-pressure blowers offer a consistent flow of fresh air that can be used across a wide range of commercial and industrial applications. Some of the most common use cases for these systems include:

  • Aeration: Blowers provide closed systems with streams of air for controlled growth of bacteria or consistent fluid aeration in operations like wastewater processing.
  • Fermentation: Blowers can provide a fresh stream of oxygen to yeast fermentation systems. The continuous stream of air reduces inconsistent growth, disruption, and risks of spoilage. A blower for each tank allows for control over the fermentation environment.
  • Pneumatic conveying: Push-style pneumatic conveyors can move bulk goods smoothly and efficiently with low-pressure blowers. The systems move bulk goods from one location to another to facilitate continuous processing.
  • Heating and cooling: Industrial production centers can cool or heat up materials at a controlled rate by blowing a continuous stream of treated air across the materials until the right temperature has been reached.
  • Additional applications

Advantages of Low-Pressure Blowers

Low-pressure blowers offer several different advantages, including the following:

  • Low energy consumption: These blowers are energy-efficient. Investing in a low-pressure blower is also more efficient than using high-pressure blowers in applications that don’t require that volume of air generation.
  • Low-maintenance: Low-pressure blowers are oil-free and do not require continual maintenance, cleaning, or lubrication.
  • Long-lasting: Because of their solid construction and low maintenance demands, blowers can have long lifespans before replacement is required.
  • Quiet: Low-pressure blowers generate very little noise during operation, allowing for a quieter and safer work environment.

Disadvantages of Low-Pressure Blowers

However, low-pressure blowers do have some limitations. This includes generating low volumes of air. While this is an advantage in use cases that don’t need large volumes or high air pressures, it can make them a poor fit for other applications.

Choosing the Right Low-Pressure Blower

There are a variety of low-pressure blower systems on the market. Consider these factors to ensure you purchase an appropriate system:

  • Type: Low-pressure blowers come in lobe, screw, multistage, and turbo varieties, and each one is ideal for different environments and needs.
  • Energy consumption: Choosing variable speed drive (VSD) units can considerably reduce energy consumption and your energy bill.
  • Specs: Determine the volume of air, the required pressurization levels, and maximum allowable noise levels.
  • Maintenance: Different units offer different lifespans, degrees of required maintenance, and installation requirements.
  • Cost: Consider both the initial purchase price and the potential ongoing costs for operation, maintenance, and energy.

One of the most important considerations is size. Not only does the unit need to be compact enough to fit in the available space, but it also needs to be big enough to generate the right amount of air (without being so big that it’s wasteful).

Types of Low-Pressure Blowers

Different low-pressure blowers use different mechanisms for drawing in and expelling air. Some of the most common types are:

  • Axial blowers: These units use rotating blade systems to pull in air, pressurize it, and expel it.
  • Centrifugal blowers: Centrifugal blowers use an impeller rather than rotating blades.
  • Rotary lobe blowers: These units feature rotating lobes inside the blower.
  • Rotary screw blowers: This is an energy-efficient option. They have incredibly energy-efficient SIGMA profile rotors that use up to 35% less energy. Kaesar’s screw blowers combine high-efficiency blower components with an efficient transmission system and high-performance drive parts. These units comply with ISO 1217 standards.
