Serie GEA Grasso M
Serie GEA Grasso M
The GEA Grasso M series comes in eight sizes with a swept volume ranging from 231 to 870 m³/h / 136 to 512 cfm (at 2,940 rpm).
La integración del filtro de succión y la carcasa del acoplamiento simplifica el montaje del paquete. La extraordinaria eficiencia energética de estos compresores se basa en su capacidad infinitamente ajustable, combinado con su rango Vi variable extendido (relación de volumen interno). La velocidad variable entre 1.000 y 6.000 rpm asegura un amplio rango de funcionamiento y una máxima eficiencia con carga total y parcial.
