 Canada Blower Co. now offers gas-tight and zero leakage fans and blowers for containment of hazardous organic and inorganic compounds in industrial process plants and other critical applications. Special construction and shaft sealing devices are available for blower service requiring zero or minimal gas leakage into and out of casing. Canada Blower has a lot of experince with gas-tight and zero-leakage construction on fans and blowers, including: multistage lip shaft seals; Buna-N, Viton and Teflon seals; mechanical shaft seals; special fan housing gasketings; single and double carbon ring seals; hermetically sealed blowers; magnetofluidic and ferrofluidic seals; and packed stuffing boxes with barrier liquids and purgeable seals. Click our website for major selection Specific code welding processes and special fan design features are used too - to ensure complete gas tight integrity. As an intermediate step between standard fan design and air-tight design, Canada Blower offers a few stages of low leakage construction on fans and blowers - for industrial customers calling to minimize leakage fans due to the presence of toxic or corrosive gases in the airstream. As some system requirements are more stringent than others, and since some of the necessary modifications can be rather expensive, a few levels of Low Leakage Fan Construction are offered to choose from: 1) Heavy gauge housing construction with solid housing drive side, Neoprene Gasketing, and Viton, or Buna-N Rubber lip type shaft seal. 2) Full face sheet gasketing, Red Silicone or White Nitrile. 3) Contiunuosly welded fan housings; 4) Gas-purged mechanical shaft seals in lieu of lip seals - for greater sealing capability at the shaft hole opening. In order to achieve a proper sealing, the mechanical shaft seal should be purged. The recommended purge pressure is 2 to 5 PSI above the process gas pressure. Lip seals are furnished with two seal elements, each with a stainless steel spring for maintaining surface contact. The seal assembly is lubricated with" neverseeze". Mechanical seals are double or triple carbon ring seals mounted in a carbon steel housing. The seal housing is furnished with two purge ports. To ensure proper fan sealing, Soap Bubble or Chalk / Kerosene tesing of the blower assembly is performed. This ensures that continuous weld has completely sealed the housing seams (liquid tight). Zero leakage and gas tight fans and blowers could be used in the following industries: * Pollution Control * Pulp and Paper Industry * Printing and Converting * Chemical Plants * Power Generation * Research and Development * Petroleum * Food Processing * Paint and Ink Industries

 

 

Fans and Blowers

Illinois Blower Illinois Blower
Pulp and Paper Industry

Severe, corrosive Pulp and Paper environments require rugged, well built equipment. Whether you need a blower to handle non-condensable gases, sulfur dioxide or for other process and conveying needs, contact us to provide a durable, dependable unit for your specific application.

High-Tech / Research & Development

Research and Development applications frequently demand critical parameters such as absolute zero leakage (hermetically sealed) blowers or the ability to handle wide pressure and temperature extremes. Whether you are working with cryogenic temperatures down to -300 degrees F or at system pressures above 120 PSIG, Illinois Blower has the experience to meet your needs.

Pollution Control/Environmental System

Illinois Blower designs and builds fans for critical Pollution Control requirements; especially in harsh corrosive environments. We have experience with steam jacketed blowers for sulfur service, special alloy units for very corrosive gases and gas tight, zero leakage blowers for critical containment applications.

Power Generation Industry

We understand that expensive down time cannot be tolerated. Illinois Blower manufactures reliable, heavy duty, low maintenance, forced and induced draft fans, cooling blowers and ventilation fans specifically for the Power Generation industry.

Petro-Chemical Industry

Illinois Blower provides a wide range of heavy duty centrifugal blowers to the Petro-Chemical industry. Typical applications include fans for gas tight sulfur and benzene service, co-generation duty or high temperature induced draft fan use. We can meet stringent end user and API specifications.

Our Custom Uniblock Bearing

As part of Illinois Blowers commitment to excellence, we have designed our own heavy duty Uniblock bearing specifically for blower requirements. This unit, when used in critical applications, can extend bearing life, reduce vibration and eliminate bearing misalignment. For increased reliability, provisions exist to add vibration and speed monitors, temperature detectors or internal space heaters.

When a single centrifugal fan within the system cannot deliver sufficient airflow and pressure or if the fan is too large to install in the desired space, then multi-stage fan systems are used as an alternative for single fan system. Two or more separate centrifugal fans can be operated either in series or in parallel arrangements to serve specific requirements of industrial applications. When an increased volume or pressure becomes necessary for a process applications, multiple fans systems can be used either in series or parallel operation rather than simply replacing the original fan with larger capacity. Using centrifugal fans in multiple fan arrangements offer greater flexibility in unit sizing and also reduce the system noise.

Centrifugal fans in series operation

In series operation, fans are installed in series close to each other like in push-pull arrangement, so that the first fan in series supplies air pressure into the inlet of the second fan. If the fans have the same system resistance, then together they produce a greater pressure difference.In series operation, each fan will have different inlet pressures. Since the first fan pressurizes the gas before supplying it to the inlet of the second fan, there is an increase in the specific weight of the gas at the inlet of the second fan. Accordingly, the second fan in series will experience greater pressure differential across the system and draws greater shaft power than the first fan. The air pressure doesn't simply double when two fans with the same capacity are operated in series arrangement. However, by arranging two fans in series, the static pressure capability of a given airflow can be increased. Since the individual performance of each fan is not the same, the fans will handle the same mass flow of air but not volumetric flow rate. Series blowers arrangement is suitable to high resistance systems, that have long ducts or large pressure drops across system components. When fans are coupled in series, it is not advisable to run one fan with the other off as the pressure drop across it will make the other fan inefficient.

Centrifugal fans in parallel operation

Unlike ventilators in series operation where typically two fans are involved, parallel operation use multiple fan systems arranged together side by side. In parallel arrangement of two fans, each fan is selected for half of the design flow rate. Parallel configurations are feasible for systems with large changes in air / gas moving requirements. When fans are in parallel, the combined performance of fans will result in increase in the volume of airflow.

The higher the system resistance, the lesser will be the gain in airflow rate. Hence, parallel configurations are generally not recommended for high-resistance systems. Parallel arrangements are suitable for applications where fans can operate in a low resistance almost in a free delivery condition. To achieve better efficiency, fans in parallel system must be properly sized, should start simultaneously and brought up to speed at the same rate. For controlling the airflow requirement, fans in parallel can utilize additional equipment such as dampers, variable speed drives or variable inlet vanes.
