Leybold DURADRY DD 450 – the high-performance model with high water vapour capacity

The DURADRY DD 450 delivers 450 m³/h peak pumping speed at < 1 × 10⁻² mbar ultimate pressure. Its 11 kW motor draws 11 kW at full load and 6.0 kW at ultimate pressure. At 34 kg/h, the water vapour capacity is ten times that of the smaller sizes; the manually adjustable gas ballast goes up to 130 l/min. The frame measures 1445 × 567 × 763 mm and weighs 570 kg; it is connected via DN 100 ISO-K and DN 63 ISO-K.

Robust and quiet

Hermetically sealed system without oil leakage, stainless steel cooling system, protected shaft seals and bearings, and a noise level below 64 dB(A) with silencer – the DD 450 is designed for demanding industrial processes with high gas and vapour loads.

Typical applications

Crystal pulling systems, large-area coating, battery drying, plasma cleaning and solar production.
