The LHS 410 DF-R air heater (DF stands for Double Flange, the R stands for Recirculation) is a compact double flange air heater from Leister that recycles hot air with ease. It offers an even higher air volume than the LHS 210 DF-R. Due to its particularly small design, it can be easily integrated into industrial systems where space is limited. Connecting the power supply is also very easy thanks to the well thought-out design.
