For the highest hygiene standards
Clean, controlled air is essential for quality and safety in food production. From product handling to equipment control and hygiene-critical zones, air ducts must meet uncompromising standards. Our components are purpose-built for the food industry and fully compliant with VDI 6022 – ensuring reliability, hygiene, and peace of mind.
Hygienic, safe, and compliant with standards
In food production, air technology quality is critical for product safety, process reliability, and regulatory compliance. Air ducts do more than move air – they power pneumatic controls, transport delicate products, support cleaning, and enable efficient drying of equipment and packaging. Every airflow can influence the end product, so hygiene, material integrity, and flawless engineering are non-negotiable.
Highest standards for materials and workmanship
In food processing, only materials that pose no risk to product quality may be used. That’s why our air duct components are predominantly made of stainless steel V4A (1.4404) – a material renowned for exceptional corrosion resistance, durability, and hygienic properties. Compared to conventional stainless steel (e.g., 1.4301), V4A offers significantly better protection against aggressive cleaning agents, saline environments, and high humidity – conditions commonly found in the food industry.
We also place great emphasis on surface quality. Smooth, pore-free surfaces prevent residue and microorganism buildup, enabling fast and thorough cleaning. This not only ensures hygiene but also reduces downtime and maintenance costs.
Hygiene standard for HVAC systems
A key standard for hygiene requirements in air ducts is VDI 6022. This guideline defines clear requirements for the planning, construction, operation, and maintenance of ventilation and air-conditioning systems, particularly in hygiene-sensitive areas such as food production. Its goal is to minimize the microbiological load in the air, thereby protecting human health and product quality.
Our products fully comply with VDI 6022 requirements. This means:
- Material compliance: All materials used are suitable for hygienic applications and meet requirements for corrosion resistance, cleanability, and chemical stability.
- Hygienic design: Our components are designed to avoid dead spaces, gaps, or hard-to-reach areas. This prevents biofilm formation and simplifies cleaning.
- Maintenance-friendly: Easy disassembly and reusability of our connectors enable regular inspection and cleaning – a key aspect of VDI 6022.
Wide spectrum
- Dairies and cheese factories: Compressed air is used here for valve control, conveying dairy products, or cleaning equipment. The hygienic design of air ducts is crucial to prevent cross-contamination.
- Meat and sausage processing: In this area, corrosion resistance requirements are particularly high, as aggressive cleaning agents and animal fats put heavy stress on materials.
- Bakeries and pasta production: Air ducts are used here, among other things, for conveying flour and other bulk goods. Dust explosion protection and hygienic design are essential.
- Beverage filling and confectionery production: Here, the purity of compressed air is especially important, as it can come into direct contact with packaging or even the product itself.
