Atlas Copco AWD 800 S – two-stage for low inlet pressures
The AWD 800 S delivers 862 m³/h at 50 Hz and 1032 m³/h at 60 Hz (dry air) and reaches 33 mbar(a). It is supplied without motor; it is intended for 30 kW at 50 Hz or 50 hp at 60 Hz. Inlet and outlet DN 100, dimensions 1235 × 480 × 818 mm (L × W × H), weight 490 kg.Direct replacement for SIHI LPH
The AWD S range (since 2025) replaces the earlier AWD 200 to 1680 and, according to Atlas Copco, is fully compatible in dimensions and performance with the SIHI LPH range – the AWD 800 S fits in place of a SIHI LPH75320.Applications
Two-stage for continuous operation below 200 mbar(a) – especially vacuum distillation, drying, degassing and evaporator duty.Variants of the AWD 800 S
Ehrler & Beck supplies the AWD 800 S as a stainless steel fitted version (grey cast iron with stainless steel impeller), entirely in SS 304 or in SS 316L.Features of the AWD range
