The ventilation specialists at Lufttechnik Gransee GmbH plan, design, produce and install systems for process air, ventilation, and environmental technology.

The basic components for these top-grade dust removal, exhaust extraction and bulk goods handling systems are provided by JACOB’s easy-to-install pipework system, with its outstanding series production quality. The company’s expertise ranges from standard solutions through to complex special constructions. These are manufactured using modern technical equipment in a production area measuring more than 3,000 square metres.

Increasingly, Gransee is establishing itself within the JACOB group as the preferred location for customised production and larger diameters.

This specialisation is to be further developed whilst JACOB Porta Westfalica focuses more on series production alone.
Gransee’s specialised performance is to be the vanguard with respect to group synergies.

Proven and dependable in-house products are a further core competency of Gransee’s individual and small-lot production.

Project references covering 20 years of market experience underline the company’s expertise in providing solutions for plant component construction, and especially for ventilation systems.
Lufttechnik Gransee offers a wide spectrum of sizes, special sizes, types of metal, and quality grades.


With its customised components and small-scale series, Gransee has established a strong economic position in niche markets. The company uses small-lot production and individuality to its advantage in a market where the large series-production companies have difficulty in competing due to their high level of automation. Versatile and quick, creative and competent, efficient, practical and experienced.
The customer receives what large series production companies are no longer able to provide: a tailored response to the individual wishes and requirements of the customer.
