William Alldays Alcosa RB

Impeller Sizes: 400–760mm | Max Flow: 6,500 m³/h | Max Pressure: 12.5 kPa | Blade Type: Radial

The William Alldays Alcosa RB is a centrifugal fan featuring a radial bladed impeller, designed for medium flow rates at medium to high static pressures. Impeller sizes range from 400mm to 760mm diameter, with performance up to 6,500 m³/h and pressures to 12.5 kPa. The radial blade profile makes it particularly well suited to handling dusty, fibrous, or contaminated airstreams where blade fouling must be minimised, as the open geometry resists build-up and is easy to clean.

Radial blades are highly resistant to build-up of dust, fibres, and sticky materials due to their open geometry. This makes the RB ideal for extraction of contaminated air, woodworking dust, or other particulate-laden airstreams where other impeller types would clog or become unbalanced.

The RB achieves flow rates up to 6,500 m³/h and static pressures up to 12.5 kPa, positioning it in the medium-flow, medium-to-high pressure category — suitable for industrial extraction, process ventilation, and pollution control systems.

Impeller diameters range from 400mm to 760mm, covering a practical span of duties from smaller workshop extraction systems to larger industrial process ventilation installations.
