other connection frames

Fans from this group are characterized by different connection flanges than standard ones. Blowers from the DM 02, DM 03, DM 20 series have small connections. Meanwhile, fans from the DM 140, DM 160, and DM 180 series have connection flanges corresponding to RV-2, HORNER 102, or 105 blowers. Depending on the model, they have steel or aluminum housings and inlet shutters or outlet flaps also called terminators. A wide range of electrical connections makes them applicable in many branches of industry, especially when equipping boilers with heating devices that require air supply during the combustion process.
