Hoffman & Lamson multistage centrifugal blowers are very durable, reliable and efficient machines. In the event of an unfortunate process upset or other unplanned event, having a spare centrifugal rotor assembly on site will minimize downtime and facilitate a quick repair time, ensuring that your process will be back up and running in short order.
Using our OEM parts, Hoffman & Lamson can supply a spare rotor assembly with an impeller configuration designed to match your existing aerodynamic performance.
Every rotor assembly includes:
Two-dimensional shrouded cast aluminum impellers or fabricated impellers are individually balanced and keyed onto the shaft. The complete assembly is then balanced to achieve smooth operation with the lowest vibration levels in the industry. If your machine has a balance piston design, the piston is included as art of the rotor and is balanced with the complete rotating assembly.
