Handbook of Air Conditioning and Refrigeration, 2/e > AIR SYSTEMS: COMPONENTS—FANS, COILS, FILTERS, AND HUMIDIFIERS
Because of the 90° turn of the airflow after the impeller , both total pressure and total efficiency are lower than those of a backward - curved fan , and the sound power level is greater.

ESDU 79037 B - A guide to fan selection and performance.
Within the centrifugal fan envelope, the range of pressure coefficient is achieved by varying the impeller blade angles, i.e. backward - curved blades give the lowest pressure coefficients, radial blades give intermediate values and forward-curved, the highest.

Proceedings of the XIII International Congress on Electricity Applications
For example, for a fan total pressure of 1200 Pa, fans with forward curved blades result in a SFP of3 kW/(m3/s) whereas backward curved impeller fans achieve a SFP as low as 1.8 kW/(m3/sy7.
