Agriculture

Compressed air plays a vital role in modern agriculture by improving efficiency, automation, and precision across a variety of farming operations. It is used in tasks ranging from planting and harvesting to animal care and equipment maintenance. Common applications include:

• Material Conveying
  Compressed air is used to transport grains, seeds, and feed by mixing air with the material to facilitate smooth, efficient movement through pipes or systems—reducing manual labour and contamination risks.
• Farm Equipment Operation
  Pneumatic systems power equipment such as automatic seeders, fertilizer spreaders, and crop sprayers. For example, compressed air assists in automated lettuce planting and precision planting technologies.
• Milk Production
  In dairy farming, compressed air is used to operate milking machines, control valves, and cleaning systems, ensuring hygienic and consistent milk extraction.
• Greenhouse Automation
  Pneumatic controls regulate ventilation, misting, and irrigation systems within greenhouses to maintain optimal growing conditions.
• Livestock Care
  Compressed air is used in systems for feeding, manure handling, and automated cleaning to improve hygiene and reduce labour.
• Pneumatic Tools and Maintenance
  Air-powered tools are widely used in farm maintenance tasks such as repairing equipment, maintaining tractors, and inflating tyres.
• Crop Spraying
  Compressed air is utilized in precision spraying systems for pesticides and fertilizers, ensuring even coverage and reducing waste.

Dairy industry - milking

In addition to transporting the milk, the vacuum used in milking systems performs other tasks as well, such as attaching onto the udder and holding the weight of the milking claw assembly to the teat.

Evisceration

Before any further processing can take place, fish and molluscs must be gutted and cleaned. Worktables are outfitted with suitable vacuum nozzles that extract the entrails from the fish. A central vacuum system then pipes the combination of liquid and coarse particles through a filter where they are separated for proper disposal. The same is possible in the poultry sector.

Fish farms

In fish farming pneumatic conveying systems are used to feed the fish. These pellets are susceptible to damage and valuable feed can be lost during pneumatic conveying of feed pellets from the feed barge to the sea cages. Using variable speed drive side channel blowers avoid this complication while at the same time taking up only a quarter of the space needed for other technologies. Minimum maintenance and very low noise and vibration levels are further key features.

Pond aeration

The water's oxygen content can be substantially increased using gas ring blowers or liquid ring pumps, which in turn increases the number of fish that can be kept in a pond twofold or even threefold.

In this process air is drawn from the atmosphere and forced through an inlet into the tube aerator. It is then diffused into the water through tiny openings and rises in fine bubbles. The oxygen in the water causes the fish to grow and multiply more rapidly and significantly increases the yield.
