Agricultural machine

Karl Barth AG Ventomat Typ SE-1-100-4p

Dry hay, biomass, or a drying container with a user-defined air volume, instead of running a fan at full speed and incurring the associated costs.

This Karl Barth AG Ventomat SE-1-100-4p was purchased in December 2025 and used for approximately four months. It operates perfectly and is offered as a complete, ready-to-use system, including more than just the fan: a factory-configured 5.5 kW Invertek Optidrive E3 frequency inverter with disconnect switch, duct cone and reducer, plus a free 10m Ø400mm fabric hose. Original purchase price approximately CHF 8,507.

Only one unit available – sold as a complete set with the inverter, ducting accessories, and hose. Once sold, it's gone.
Best for: hay drying, biomass drying, drying containers, and agricultural ventilation where controlling air volume is preferred over continuous full-speed operation.
Not suitable for: corrosive or heavily dust-laden air streams, or ATEX zones unless independently verified.

What the specifications mean in practice:
• 5.5 kW motor, 4 kW rated fan output – sized for continuous hay/biomass drying, not short bursts.
• Factory-configured Invertek Optidrive E3 inverter – adjusts air volume to the crop and its moisture content, reducing energy consumption.
• Inverter in IP66/NEMA4X enclosure with disconnect switch – can be mounted in a dusty barn without a separate control cabinet.
• Duct cone 222/563 to D400mm and D750/D600mm reducer – connects to existing ductwork without requiring custom fabrication.
• 10m Ø400mm flexible fabric hose included – allows flexible positioning of the fan and ducting to where needed.
• Painted sheet metal, single-suction Swiss-made (Karl Barth AG) – durable and locally supported.

Complete package includes: Ventomat fan, Invertek Optidrive E3 5.5kW inverter with disconnect switch, duct cone 222/563 to D400, duct reducer D750/D600 with flange ring, and a 10m Ø400mm fabric hose – all at no extra charge. Purchasing and configuring the inverter alone represents a significant additional cost.
