New sickle impellers

has launched a range of sickle impellers into the

market. Designed specifically to meet the demands of the

, the sickle impellers can reduce noise by up to 4db.

The new sickle range was developed to satisfy the increasing demand for noise reduction in all areas of industry. The design of the sickle impeller reportedly creates a larger pressure at a lower RPM. This is due to both the leading point of the blade which ‘pierces’ the air first and the thin trailing edge that reduces drag, delivering significant noise reduction and increased efficiency.

The initial sickle range includes Z and W type impellers; the 1Z and 2Z are specifically designed for the heat exchange and engine cooling markets, whilst the 1W and 2W are targeted at the larger diameter refrigeration and fan markets. Two smaller diameter fixed pitch H types will be added for the heat exchange and fan markets in the first quarter of 2006.
