• Read and follow all instructions in this manual. If you have any questions, consult your Spencer Representative. • Use appropriately rated lifting equipment for installation, removal or disassembly of heavy components. Standard Overhung Design These Spencer blowers are multistage centrifugal units which handle air and other gases, working either as blowers or exhausters. They increase the pressure of the incoming air or gas by guiding it from one stage to the next through diffusers. They are centrifugal because the flow through the blower is turned perpendicular to the axis of rotation. The...

Each Spencer blower is carefully balanced and tested at the factory. For optimum performance, it must be handled with care during unloading and installation. Check the shipment for damage upon arrival; file any claims with the shipper and notify Spencer. Moving of this equipment is the customerʼs responsibility and should be performed or directed by experienced riggers using accepted rigging practices and safety precautions. The blower/ motor assembly can be lifted and relocated with a forklift, overhead crane or hoist. Always use lifting equipment rated for the loads involved. Consideration...

To regulate (throttle) blower volume and/or pressure, a butterfly valve may be installed—preferably on the inlet. A valve may also be installed on the discharge as an isolation valve. Spencer blowers will accept a filter or filter silencer, typically on the inlet, and a silencer, typically on the discharge. Inlet filtration is recommended for pressure applications. Orient the check valve during installation to equalize loading on the valve shutters. Usually, the hinge post of the check valve should be installed perpendicular to the blower shaft. If the check valve is installed in a horizontal...

Laser systems have significant advantages such as reduced maintenance costs and energy consumption; prolonged life for bearings, seals and couplings; decreased bearing temperatures and lower vibration levels. Many laser systems also identify and measure soft foot conditions. NOTE: Consult an alignment specialist if laser equipment is not available. Use a flange-type gear coupling for both 1800 and 3600 RPM motors. Do not use a sleeve-type coupling. Sleeve bearing motors have a specified end play. End play limits and the magnetic center (where motor will run) should be scribed on the shaft by...

Before operating a new blower for the first time, review its installation and setup to be sure that no steps have been overlooked. • Is there any damage from transportation or installation? Packing Box Carbon Ring • Have all packing, shipping materials and tools been removed? • Is the inlet filter in place? • Are isolation pads in place? • Is the piping connected and supported? • Are flexible connectors in place between blower and piping? • Are safety guards in place? • Is the coupling aligned within tolerances and lubricated? (4BOB & 4BOH blowers only) Mechanical Seal Shaft seals at both the...

A blower in surge produces a rush or pulsating rhythmic air sound caused when airflow into or out of the blower is restricted. In addition to its characteristic noise, surge may be detected by power or pressure fluctuations. Surge is destructive because it is accompanied by excessive temperatures and aerodynamic forces that will ultimately cause mechanical failure. A surge condition is simply eliminated by increasing the airflow either into the system or to a bypass or vent. Various surge control devices are also available from Spencer—see page 5. NOTE: If a blower surges violently at startup,...

NOTE: More bearing failures are caused by overgreasing than lack of lubricant. Always add grease sparingly. CA UTION: Us e Chevr on SRI #2 g rease.
