Fans Performance Curves   By: Oleg Tchetchel
The fan curve presents fan performance. It is one of the most useful tools available during the fan selection process. While multi-rating tables are convenient (see page 12), performance curves offer additional information such as - how much reserve pressure head exists between the design pressure and the peak static pressure, the maximum power the fan might draw, and the efficiency of operation.(read entire article)

Fiberglass Blowers   By: Oleg Tchetchel
FRP Pressure Blowers are designed for highly corrosive application to handle acid vapors, and organic and inorganic chemical fumes that are highly corrosive to metal at temperatures up to 250 F. Applications include scrubber systems, odor control systems in wastewater treatment plants, laboratory exhaust systems, metal finishing and chemical-process industries. Fiber-reinforced-plastic pressure blowers are made from chemical grade polyester or vinyl ester resins and reinforced with glass or fiber. Additional surface veil is available depending on the application. Capacity range of FRP Pressure Blowers is from 0 to 8,000 CFM and static pressure range is up to 40 WG.(read entire article)

Fiberglass Pressure Blower   By: Oleg Tchetchel
Potential applications for FRP fans include any process in which corrosive fumes must be captured, moved, cleaned, or vented. FRP fans are most often used in fume-scrubber systems where the scrubber itself may be constructed of FRP or an exotic alloy, but where FRP is the preferred fan material. Galvanizing and etching processes often have FRP exhaust hoods and ducts, and many of the fans used to convey fumes in such systems are also built of FRP. Waste water treatment plants and laboratory exhaust systems are other applications for which FRP fans are being used with increasing frequency.(read entire article)

Forced Draft Fans And Blowers   By: Oleg Tchetchel
Forced ventilation is a method of control indoor air quality. Excess humidity, odors, and contaminants can often be controlled via dilution or replacement with outside air. However, in humid climates much energy is required to remove excess moisture from ventilation air.(read entire article)

Frp Industrial Blower Fan   By: Oleg Tchetchel
All polyesters and vinyl esters are corrosion resistant to some degree. Industrial process applications involve a wide variety of corrosive gas streams. Selecting the best materials of construction for air handling equipment can be difficult. This article provides information about the corrosion resistance of the resins used to manufacture standard FRP fans.(read entire article)

High Temperature Exhaust Ventilator Fan   By: Oleg Tchetchel
Generally speaking, emergency smoke evacuation fans may never be used, but they must be installed and be capable of exhausting high temperature air and smoke in the event of a fire. In contrast, high temperature process ventilation requires continuous duty exhaust of high temperature air, fumes or particulate. Both application types are uniquely different requiring special construction and system design considerations. In this article, we will examine both types of exhaust applications, looking first at the emergency smoke exhaust category. Since emergency smoke exhaust deals with lifesafety issues, there are governing bodies in place that identify and regulate specific design and performance standards. The administration and organization of the various governing bodies is subject to modification based on the needs of the industry. Currently, four such agencies are Industrial Risk Insurers (IRI), Southern Building Code Congress International, Inc (SBCCI), the National Fire Protection Association (NFPA), and Underwriters Laboratories, Inc. (UL). IRI insures properties all over the world based on an informational manual, which details the construction requirements that belt drive emergency heat and smoke exhausters must meet in order to be covered by IRI.(read entire article)

How To Increase Blowers Performance   By: Oleg Tchetchel
The proper design of the ventilation system plays a large role in achieving the overall desired performance. Visual inspections often reveal some easily rectified problems that can significantly impair performance. If the system has not been properly maintained, clogged filters or obstructed coils will reduce airflow. The greater the obstruction, the greater the loss in airflow. Any leaks in the ductwork will contribute to reduced performance, especially leaks around plenum bulkheads that can lead to recirculation of air. Worn flexible connectors are a common source of leaks and should be inspected regularly. If the damper linkage is out of adjustment, the damper may not be opening completely, thereby reducing performance. If inlet dampers are used, make sure they are installed so that the air is pre-spun in the same direction as wheel rotation. For all dampers, make sure there is sufficient clearance for the blades to open and close completely without hitting the ductwork or other system components. Last, for systems with either pneumatic or electric controls, make sure damper actuators are operating properly. Sharp changes in the direction of airflow at either the fan inlet or outlet will disrupt the flow through the fan and impair performance. If it is impossible to straighten the ductwork entering and leaving the fan, the use of inlet boxes and turning vanes can minimize performance losses.(read entire article)

How To Ventilate Big Building   By: Oleg Tchetchel
Power roof ventilators of the type manufactured by Canadian Blower are very similar in basic design to the wall fans. Size and capacity closely parallel the wall fans. One of the most popular Canadian Blower PRVs is the upblast exhauster. This unit utilizes air velocity to expel rain or snow that may try to penetrate into the structure. When the unit is not in service, butterfly dampers effectively seal the opening against the weather. Because of the straight through air flow design, this is the most effective and efficient PRV available.(read entire article)
