Waste Water Blowers & Control Systems
Howden’s single and multi-stage centrifugal blowers provide low volumes of air at high pressure, packaged complete with control systems, for waste water treatment duties.

In Africa Howden’s Type RRC centrifugal blowers are directly coupled to two-pole induction motors, offering a cost-effective, efficient and quieter alternative to positive displacement blowers. Our blowers are supplied in a wide range of corrosion, abrasion and temperature resistant materials to meet the specifications of the individual customer.

Key benefits

• Uninterrupted operation through a variety of flows
• Wide flow range
• Integrated control system

Standard features

• Efficient
• Robust construction

Howden’s centrifugal blowers are fitted with inlet inducer vanes, inlet radial valve controls and optional variable vane diffuser controls to operate at very high efficiency over an extremely wide flow range.

Our blowers incorporate fully-fabricated impellers and casings, providing for an extremely wide range of readily welded material options for construction. Impeller inlet and stationary inlet cones are machined to ensure optimum aerodynamic performance, and each impeller stage is fitted with a set of inlet control vanes that provide high efficiencies over wide operating ranges.

Our engineers can customise each blower’s control system for specific customer requirements and performance demands.

Maintenance is simplified and our units do not demand any special skills other than those normally associated with fain maintenance and service.

Howden offers turnkey electrical control and automation products that are engineered for the customer’s process specifications. We manage the complete automation of large projects, from the tender stage, through to final commissioning.
