Clean air for clean kitchens

In professional kitchens, large amounts of fats, vapors, and odors are generated daily – a real challenge for any ventilation system. With our high-quality products and system solutions for airtight air ducts, you ensure safe, hygienic, and efficient air exchange. Whether restaurant, large-scale kitchen, or food truck: we offer the right solution for every gastronomic environment.

Clean, safe, and reliable

In gastronomic operations, air ducts are a key component for hygiene, safety, and efficiency. The requirements for these systems are particularly high: extreme temperatures, grease-laden exhaust air, and aggressive cleaning processes directly affect the materials and components used. This is exactly where our products come in.

We supply air duct manufacturers, system builders, and specialist companies for cleaning and maintenance with high-quality individual components specifically developed for use in ventilation systems for the foodservice industry. Our product range includes air duct profiles, fastening elements, sealants and tapes, and other accessories that stand out for their reliability and durability.

Special attention is given to material selection: For applications in gastronomy, metallic components made of stainless steel (1.4404) are recommended. This material offers excellent corrosion resistance and significantly facilitates cleaning, which is crucial in environments exposed to grease and oil.

Our products comply with common international standards and guidelines and can therefore be used worldwide in professional ventilation systems. We do not see ourselves as manufacturers of air ducts but as a reliable partner for supplying the necessary individual parts.

With our many years of experience and technical expertise, we support our customers in realizing powerful and compliant ventilation systems – for a safe and clean kitchen environment.

Challenges in gastronomy

Air ducts in kitchen environments are exposed to special stresses:

  • Grease- and oil-laden exhaust air
  • High temperatures and humidity
  • Cleaning and disinfecting agents
  • Strict hygiene requirements

Our products are specifically designed for these demands and ensure permanently airtight, hygienic, and maintenance-friendly air distribution – even under extreme conditions.

Your benefits with our solutions

Maximum airtightness

Our components enable the construction of airtight systems in accordance with the highest standards. This reduces energy losses, prevents the escape of grease-laden exhaust air, and protects adjacent components from contamination and corrosion – a crucial factor for the operational safety and longevity of your system.

Hygienic design

All materials and sealants used are suitable for use in hygiene-critical areas. They are easy to clean, resistant to aggressive cleaning agents, and comply with the requirements of VDI 6022.

Material resistance to fats, oils, and cleaning agents

Our sealants, sealing tapes, and profiles are specifically designed for the conditions in kitchen environments. They remain dimensionally stable and fully functional even under continuous exposure to grease-laden exhaust air, water vapor, and cleaning chemicals – ensuring safe operation at all times.

Flexible application for rectangular and round air ducts

Whether standard size or custom solution – our products can be flexibly adapted to your structural conditions. They are suitable for rectangular and round air ducts, for new installations as well as for retrofits or refurbishments during ongoing operations.

FAQ

We offer a wide range of components such as air duct profiles, mounting brackets, support rails, sealants, sealing tapes, flexible connectors, screws, and other accessories for the manufacture and installation of air ducts.

No, we do not manufacture air ducts. Our customers – usually ventilation or plant engineers – produce the air ducts themselves and use our products for their construction and installation.

Yes, many of our components are specifically designed for use in grease-laden exhaust air. They are robust, corrosion-resistant, and support hygienic, easy-to-clean air distribution.

Our components enable airtight, smooth, and easy-to-clean air duct systems – ideal for kitchen areas where hygiene regulations must be met.

Yes, many of our components are also suitable for visible installations – for example, in modern gastronomy concepts with open ceiling design or an industrial look.

Everywhere where cooking, frying, and steaming takes place

Our solutions for airtight air ducts are used in a wide range of gastronomic environments – everywhere greasy exhaust air is generated and the highest standards of hygiene, safety, and efficiency are required.

  • Large kitchens in hotels, hospitals, and canteens: High-performance exhaust systems for kitchens with heavy workloads – hygienic, durable, and low-maintenance.
  • System catering and quick-service restaurants: Standardized, flexible solutions for chain operations with high throughput and changing requirements.

Sealants

In gastronomic establishments, the highest standards for hygiene and air quality apply. To seal air ducts safely and permanently, special sealants are used that comply with the strict requirements of VDI 6022. The products Gebhardt-MAXX, Gebhardt-PLAST, and Gebhardt-MASTIC provide a reliable solution for this purpose.

Sealants

EPDM sealing tape

In the foodservice industry, hygienically flawless air distribution is essential. EPDM sealing tapes provide a reliable solution for sealing between air duct components. The elastomer material is highly resistant to moisture, temperature fluctuations, and cleaning chemicals – ideal conditions for use in kitchens and other sensitive areas.
