Ideal for hot air recirculation up to 350 °C helps save energy and costs High air volume possible The RBR short for RADIAL BLOWER RECIRCULATION Leister medium-pressure blower – also known as radial blower or radial fan – can withstand air temperatures of up to 350 °C on the inlet side due to its design. It is therefore particularly suitable for setting up hot air systems – together with the DF-R double- flange air heaters and other accessories. Such hot air systems “recycle” the hot air from the process and thus make a significant contribution to energy and cost savings. This environmental protection is perfection.
