Energy Recovery Ventilator   By: Oleg Tchetchel
HVAC system designers have realized the benefits of using Energy Recovery Ventilators (ERVs) in commercial and institutional buildings. However, as with many newly adopted technologies, questions of how best to apply this product are being raised. One application issue in particular is whether to apply an ERV as a stand alone unit on its own curb, or as a bolt-on accessory to a rooftop air conditioning unit.(read entire article)

Explosion Proof Fan Blower   By: Oleg Tchetchel
Industry areas such as chemical, pharmaceutical, and various industrial processes have explosive environments that require the equipment to be specially constructed to minimize the risk of gas or dust ignition. Fans are one of the items of industrial equipment that have potential to ignite either gas or dust from either sparks caused by contact of the fan wheel and housing, or because of fan motors with high temperatures, inadequate gas / dust ingress protection, or inadequate construction.(read entire article)

Fiberglass Blower And Fan   By: Oleg Tchetchel
When fiberglass is the selected material for an air-handling system, it is logical that the fan also be made of FRP. For example, the acids used in the pickling of stainless steel are necessarily those that attack stainless steel. In such a system, the acid resistant tanks, fume control hoods, ducts, air and gas scubbers, and fans are often made of FRP because FRP resists acid corrosion and costs less than metal alloys having comparable resistance.(read entire article)

Fiberglass Blower And Ventilators   By: Oleg Tchetchel
Fiberglass and PVC 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)

Frp Blowers Fans   By: Oleg Tchetchel
Where the user is unsure of the nature of the chemicals involved, or of the corrosive effect of the combination of chemicals involved, it is advisable to insert resin test coupons, as well as coupons of possible alternate materials of construction, into the gas stream for observation. All polyesters and vinyl esters are corrosion resistant to some degree.(read entire article)

High Temperature Exhaust Fan Ventilators   By: Oleg Tchetchel
SBCCI is a not-for-profit organization of government officials from the United States and several foreign governments, which serves a strong leadership role in the delivery of model building codes. The purpose of the NFPA can be summarized into three main categories. First, NFPA promotes the science and improves the methods of fire protection and prevention, electrical safety, and other related safety goals. Secondly, it obtains and circulates information on these subjects. And thirdly, it secures the cooperation of its members and the public in establishing proper safeguards against loss of life and property. The fourth organization is Underwriters Laboratories, Inc.. UL is a non-profit, independent organization that maintains and operates laboratories for examination and testing of devices, systems and materials to determine their relation to life, casualty hazards and crime prevention. UL has three safety standards that apply to emergency smoke exhaust products. UL 705 is concerned with the mechanical and electrical construction to insure safe operation. All electrical components (motor, wiring, switches, enclosures, etc.) must be ULlisted. UL793 is concerned with the lifting mechanism for the butterfly dampers and the fusible link. In order for a product to be listed in the UL Directory under ŇPower Ventilators for Smoke Control Systems, it must meet the requirements of both UL 705 and UL 793. Additionally, UL must witness a full-scale test of a fan operating for the required time at the specified elevated and temperature.(read entire article)

How To Ventilate Large Areas   By: Oleg Tchetchel
One of the main components of many ventilation and cooling systems is the wall-mounted exhaust fan. A mounting panel attaches the fan to the inside face of a wall opening. An automatic or motor-operated wall shutter is mounted on the outside face of the wall to provide weather protection when the fan is not in operation. These wall exhausters are available in a wide range of sizes and capacities. Chicago Blower Canada has models with blade diameters from 7" to 84". Capacity ranges from 250 cubic feet per minute (CFM) to approximately 100,000 CFM from a single fan. Fans of this type are quite efficient, dependable and require relatively little maintenance. Minor disadvantages may relate to their wall location. This location may result in interference with operations of the building, may cause damage to the fan itself or it may be a possible disturbance to personnel working in the proximity of the fan.(read entire article)
