  • CB Blower (Buffalo, New York) Ventilation Fan
    CB Blower Co. have supplied the ventilation systems and fans for many tunnels in Europe, and North America, as well as providing fans for tunnels in other parts of the world. Typical tunnel ventilation applications include:

    • longitudinal ventilation with jet fan, injector or extraction,
    • transverse ventilation of road tunnels,
    • semi-transverse ventilation of road tunnels,
    • jet fans for longitudinal tunnel ventilation,
    • skid mounted wet dust extractors to keep dust levels low during tunnel construction
  • Turbo Pressure Blower and Radial Fans
    In the past, the OEM purchased the necessary fan equipment then mounted it on its gas turbine generators. These generator sets were then shipped to job sites all over the world and installed in coastal areas, jungles, deserts and other extreme locations (even water-based applications like cruise ships and oil rig platforms). A key requirement for these applications is that the fans need to be exceptionally corrosion resistant to withstand these severe environmental factors.
  • Vaneaxial Fans from CB Blower
    CB Blower Vane Axial Adjustable Pitch Fans are used in applications where demands vary with system or seasonal change. Blade pitch is manually set to increase or decrease performance. Blades are easily adjustable externally at the hub. Available in compact direct drive models.
  • Ventilation Blower
    Based on the specific process, CB Blower products can be customized to meet the most demanding mining applications including underground ventilation, dust control systems, mineral processing, and for cooling major components in engines, braking systems and drilling equipment. CB Blower designs its fans with a number of special features such as custom motors-flex connectors, C-Damper actuators, explosion proof motors and a wide range of abrasion resistant, spark resistant and high temperature construction features. Transportation tunnels and mining tunnels must be properly ventilated — both during their construction and in ongoing use. The aerodynamics involved in ventilating these tunnels can be very intricate and require special attention to detail, especially when lives are at stake.
  • Air Handling Blower Fan
    Industrial air systems balance the required humidity of the plant air by humidifying the air during the dry seasons and dehumidifying the air when conditions are more humid. This is accomplished by using re-circulated heated or chilled water that is sprayed into the air. Buffalo Blower fans are used to draw air through these air washer systems and typically provide adjustable pitch axial fans in the range of 2.5" to 4" static pressure. Regardless of the size of your operation and system requirements, CB Blower Co. is capable of manufacturing virtually any size fan or blower to meet your exact specifications. Air strippers are used on drum filters for removing material build up on the filter. The vacuum nozzles on the filter remove the fiber / particulate which are then disposed of or used for reclaiming the material. The fans used in this particular application require higher pressure at a relatively low airflow along with a radial blade design for handling the material. Because of these factors Buffalo Blower model ORB incorporates radial blades with a backplate to prevent long stingy material from collecting around the shaft.
  • Ventilation System Design
    AMCA International defines system pressure loss as "the sum of the static-pressure losses due to friction, shock, dissipation of velocity pressure at the system discharge, and the static-pressure differences between the entry and discharge openings of an air system. The static pressure a fan must overcome is dependent on many variables, only some of which the design engineer can control. The location of equipment often is determined by the architect and, therefore, limits the engineer's options.
  • CB Blower Ventilators PRVA
    CB Blower Canada PRV Power Roof ventilators provide clear evidence of the continued leadership of Buffalo Blower Canada in the engineering development and manufacture of ventilating fan packages for industrial and commercial ventilation. CBC Company axial roof fans cover sizes ranging from 15" to 84" wheel diameters with capacities from 2000 CFM to 200,000 CFM.
  • Ventilation System Calculating
    Air Movement and Control Association (AMCA) International defines system pressure loss as "the sum of the static-pressure losses due to friction, shock, dissipation of velocity pressure at the system discharge, and the static-pressure differences between the entry and discharge openings of an air system. The static pressure a fan must overcome is dependent on many variables, only some of which the design engineer can control. The location of equipment often is determined by the architect and, therefore, limits the engineer's options.
  • Industrial and Industrial Air Handling Units
    Air-handling Units for Make Up Air and Space Pressurization Applications have the following features:

    - Outlet Temperature is usually monitored with a probe mounted near the outlet of the unit.

    - Discharge Air Temperature is set at the control panel or using a remote control station.

    - Gas input is “modulated” using a butterfly valve, actuator, and controller.
  • Commercial Air Make Up Units for Indoor Air Control
    Ventilating Fan Co. is a distributor and engineering representative for Direct-Fired Make-Up Air Systems for air temperature control at large industrial plants.
  • Practical Methods of Ventilating
    Exhaust fans are usually located near the area where heat-producing machinery is found in the industrial building. This has the very practical advantage of exhausting this superheated air near its source and preventing a heat build-up in other areas. If side wall locations are to be utilized for air intake or exhaust, it is desirable to consider the prevailing wind direction during the summer season. If the ventilation system can be oriented to take advantage of prevailing winds, the efficiency of the system may be increased considerably, Systems that incorporate roof exhausters are usually not affected by a prevailing wind.
  • Gas Fired Industrial Makeup Air Units
    Gas Fired Pressurization Units move large quantities of air at low temperature differentials (usually 50° or less), which is a strategy to minimize temperature stratification in the large spaces they are employed to heat. The equipment is typically mounted on the roof of the facility or at grade on elevated supports to ensure that the supply air is delivered high. The high air delivery allows for a longer “throw” of the air, thereby requiring less equipment to cover the required floor area. The most common fuel is natural gas, however, units can be converted to burn propane. There are two primary categories of gas-fired AHUs: indirect-fired and direct-fired.

  • Recommendations for Building Ventilation and Cooling
    Ventilating Fan Co. has offered a few techniques of effective building ventilation and cooling. In industrial plants where there is a high density of employees and many manual operations involved, an improvement in the environment can produce substantial benefits in terms of increased production, reduced errors, and a decline in complaints and absenteeism among employees. In other circumstances, the attentiveness of an audience or student group may be a factor that spells success or failure.
  • Residential Electric Steam Humidifiers SKR
    The recommended indoor relative humidity (percentage of moisture in the air) level is 35%.
  • Electrical Steam Humidifiers with Steam Distribution Blower Unit
    Humidity not only affects your home itself, but also a wide variety of contents. Low humidity is the main cause of static electricity in a home. Dry skin and dry carpets are great for creating the friction required to send sparks from you fingertips into anything you touch. With all the highly sensitive electronics equipement (from stereos and tv's to computers) in homes today, static electricity can be a major threat. It doesn't take much of a spark to harm that expensive piece of electronics.
