CONTINENTAL Multi Stage Centrifugal Blower

Blower performance as shown with standard air @ 68°F, 14.7 PSIA and 36% RH.

Capacities depict blower performance, direct driven, at a speed of 3600 rpm.

Blowers are typically driven by a direct coupled, 3600 rpm electric motor. Special drives include V-belt arrangements, steam turbines, gear-box, gas engine, and variable speed electric motors. Special drive arrangements are available upon request.

Machines may be piped in parallel for increased volume requirements.

Machines may be piped in series for increased pressure or vacuum requirements.

Blower or exhauster capacity may be regulated by means of an inlet butterfly valve or a variable speed driver

Design Features

 Casing: Cast iron or cast aluminum housings, held securely by steel tie rods. Sections are standard with internal and/or external drains

Shaft: Polished carbon steel or stainless steel for corrosive gas applications Impellers: Cast or fabricated high strength aluminum, available in radial or backward curved vane configurations

Bearings: Outboard mounted, grease or oil lubrication, sized for minimum 10 year bearing life. Optional water cooled bearings are available

Seals: Carbon/graphite rings, single for air or double for gas applications, purge capability available

Baffle Rings: For improved airflow into the impeller eye, resulting in higher efficiency and improved performance

Balance Piston: Used to absorb up to 75% of the axial thrust load in blowers operating at higher flows and pressure ratios

Bearing Housing: Cast iron housing with labyrinth seals to protect lubricant from contamination

Cooling Fans: Models 77 and larger incorporate cast aluminum cooling fans to assist heat dissipation
