  • Page 7: Specifications

    Specially ordered blowers with nonstandard construction, or with rotor end clearances greater than shown within the Assembly Clearances table, will not have the operating limits specified here. Contact your Tuthill Vacuum & Blower Systems sales representative for specific information. NOTE Special attention must be paid when a blower has a higher than standard ambient suction temperature.

  • Page 8: Installation

    5. INSTALLATION 5.1 GENERAL DANGER The blower is not intended to be used with explosive products or in explosive environments. The blower is not intended to be used in applications that include hazardous and toxic gases. Consult the factory for support. DANGER It is the responsibility of the installer to assue that proper guarding is in place and compliant with all applicable regulatory requirements.
  • Page 9 NOTE In the event that your unit sustains damage while being shipped to your facility, do not return it to the factory without first obtaining shipping instructions from us. Protective covers and plugs should not be removed until the connection is being made. Mount the blower on a flat, level surface.

  • Page 10: Location

    (See the Motor Drives section for more information.) Blowers from Tuthill Vacuum & Blower Systems are internally and externally treated after factory assembly and testing to protect against rusting in normal atmospheric conditions prior to installation. The maximum period of internal protection is considered to be up to 6 months under average conditions, provided closing plugs and seals are not removed.

  • Page 11: Soft Foot

    Figure 4 - Illustrations of Soft Foot 5.2 SAFETY Tuthill Vacuum & Blower Systems recommends the use of relief valves to protect against excessive pressure or vacuum conditions. These valves should be tested at initial start-up to be sure they are properly adjusted to relieve at or below the maximum pressure differential rating of the blower.

  • Page 12: Lubrication

    5.3 LUBRICATION Every blower from Tuthill Vacuum & Blower Systems is factory tested; oil drained and shipped dry to its installation point. Both oil reservoirs must be filled to the proper level before operation. The blower incorporates pressure lubrication with an integral oil pump, pressure relief valve, filter and oil-to- coolant heat exchanger.

  • Page 14: Frequently Asked Questions Regarding Lubrication

    5.3.2 FREQUENTLY ASKED QUESTIONS REGARDING LUBRICATION What is the functional detriment if the “wrong oil” is used? The lubricant is selected based on bearing and gear speed, and operating temperature. Too light of a lubricant increases wear by not separating the sliding surfaces and it will not remove the heat adequately.

  • Page 15: Lubrication - Integral Pressure

    5.4.3 OIL FILTER The oil filter is self-contained. With every oil change, change the oil filter element and it’s shell gasket, both available from Tuthill Vacuum and Blower Systems in Springfield, Missouri, or from any authorized distributor or service center.

  • Page 16: Piping Connections

    5.5 PIPING CONNECTIONS WARNING Pipe loading on the blower should be negligible as pipe loading can cause distortion of the blower. Use proper supports and pipe hangers to assure that there is no loading. NOTE Remove the protective covers from the inlet and outlet ports and inspect for dirt and foreign material.

    5.6 MOTOR DRIVES Two drive connections commonly used are direct drive and V-belt drive. 5.6.1 DIRECT COUPLED When installing the motor directly to the blower, align shafts to coupling in accordance with the coupling manufacturer’s instructions. Blowers shipped with motor directly coupled and mounted on a common base have been aligned prior to shipment and normally no further alignment is necessary.

  • Page 22: Stopping

    WARNING The blower can generate excessive noise, hearing protection is required while the unit is in operation. CAUTION Do not touch hot surfaces. The upper limit of the blower operation is º F ( º C). Do not touch the blower while it is in operation and assure blower is cool when not in operation.

  • Page 23: Shutdown

    However, due to the wide variations in mineral content, pH, and chemical content of water that can be injected, Tuthill Vacuum & Blower Systems cannot be responsible for damage which may result should this build-up occur. Units should be inspected regularly to determine any problems.

  • Page 24: Maintenance

    3. For extended shutdown, inject a small amount of a light lubricating oil such as 3-in-One or a spray ® lubricant such as WD-40 into the inlet of the blower just prior to shutdown. (3-in-One and WD-40 are ® registered trademarks of WD-40 Company.) The lubricant will provide an excellent protective coating on the internal surfaces.
