  1. By drying containers more quickly and reliably, air knife systems can help improve production line speed and output, leading to increased revenue for the brewery.
  2. Air knife systems are more effective at drying containers than compressed air systems, which reduces the need for manual labor—saving breweries money on labor costs and allowing employees to focus on other tasks.
  3. Air knife systems can help to reduce downtime on the production line, due to their reliability, ease of maintenance, and consistent performance. This can improve overall productivity and reduce costs associated with downtime.
  4. More thorough drying ensures that containers are clean and ready for filling, reducing the risk of contamination or spoilage and associated costs.
  5. Finally, air knife systems can help reduce waste from throwing out containers that are damaged by water, such as cardboard boxes, saving breweries money on materials and disposal costs.


Upgrading to a Craft Brewery Air Knife System can save money, improve consistency and customizability, provide quieter operation, and achieve more thorough drying of containers.


Q: How loud is a blower compared to compressed air?

A: Blowers used in Republic’s Craft Brewery Systems operate between 70-85 dB. When coupled with an external silencer and/or sound enclosure, centrifugal blowers can be up to 50% quieter than air compressors. Additionally, Republic air knives are designed to produce a low-volume, high-velocity stream of air, reducing noise levels even further. This air stream is a vast improvement compared to traditional compressed air systems, which can disrupt the work environment and cause hearing loss over time.


Q: How do I remove condensation from a bottle before labeling or printing?

A: An air knife and blower system is the most efficient and cost-effective way to remove condensation and moisture from a surface and ensure proper adhesion of labels and printed ink from date coders.

Air knives work by directing pressurized air into a uniform gap, which creates a laminar flow pattern capable of shearing away moisture, dust, or other contaminants without mechanical contact. Powered by the steady flow provided by a centrifugal blower, air knives are the fastest and most thorough way to dry a surface, remove particulates, and prepare it for labeling and printing.


Q: How many passes does it take to completely dry cans or bottles with an air knife?

A: Craft Brewery Air Knife Systems are designed to achieve a dryness level of 99.9% or higher, ensuring your containers are ready for filling.

Compared to traditional compressed air systems, which can leave moisture behind in hard-to-reach areas, Craft Brewery Air Knife Systems are more effective at removing moisture from all container surfaces. This helps to ensure that the containers are fully dry and ready for filling, reducing the risk of product spoilage and meeting or exceeding industry standards for product quality.


Q: Can I dry all sides of the cans or bottles?

A: Republic Air Knife Systems are designed to dry every surface of the cans and bottles. The air knives are strategically placed to ensure that every part of the container is thoroughly dried, including the bottom and hard-to-reach areas.

The location of the air knives and direction of airflow can be customized based on the unique needs of each brewery’s production line.

For example, placing an air knife at the bottom of the container can ensure that any remaining water droplets are removed before the container is filled with beer or other liquids. Similarly, placing air knives in hard-to-reach areas, such as the top of bottles, can ensure that all sides of the container are thoroughly dried. The placement of air knives can also be optimized to ensure optimal drying performance based on the container size, shape, and production line speed. For instance, if the production line speed is high, air knives may need to be placed closer together to ensure that containers receive sufficient drying time.


Q: Can I customize an Air Knife System to fit my brewery’s unique canning or bottling line?
