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
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.

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 -
customers calling to minimize leakage fans due to the presence of toxic
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
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
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
* Food Processing
* Paint and Ink Industries
Fans and Blowers
|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
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.
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.
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
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
