A
new high pressure MVA series mixed flow in-line ventilators finally
resolves
the problem of pushing air through high resistance and long ventilation
ducts.
Mixed Flow fans are an excellent choice for return air, supply, or
general
ventilation applications where low sound is critical. As compared to
similarly
sized tubular centrifugals and vane axials, a mixed flow fan will be
5-20
dB quieter! In addition, the mixed flow wheel is extremely efficient
and
will cut down on operating expenses.
Unique features of the MVA Mixed Flow Fans include:
- Universal Mounting System that allows the unit to be field rotated at
the
job site
- Compact design with standard slip-fit duct connections for ease of
installation
- UL/CSA listing for electrical is available
- Continuously welded housing with a standard powder paint finish
suitable
for indoor or outdoor applications
- A complete three plane vibration test of all assembled fans prior to
shipment
The feature that
differentiates
a Direct Gas-Fired Heating System from other types of heating equipment
is
its burner system. A “trough” or “line” burner is installed directly in
the
supply air stream. Combustion products are introduced into the building
space
during operation.
The key advantages are simplicity and efficiency. No heat exchanger is
required.
This eliminates component installation and maintenance costs. With no
heat
transfer losses, the unit is nearly 100% efficient.
The primary disadvantage is the introduction of waste products into the
airstream.
For this
reason, both ANSI Z83.4/CSA3.7 and ANSI Z83.18 standards state:
“Heaters
covered by this standard are intended for use in industrial and
commercial
applications.” ANSI Z83.18 states further that: “Heaters covered by
this
standard are not intended for use in any area containing sleeping
quarters."
Carbon Monoxide and Nitrogen Dioxide are the primary pollutants. These
are
limited to no more than 5.0 PPM for CO and 0.5 PPM NOX, a fraction of
OSHA
allowable Permissible Exposure Limits(PEL’s).
Buffalo Fan Co. distributes
new
style of Low Profile Positive Pressure Ventilators that have been
designed
to fit in tight compartments ans small spaces without scarificing
performance
or features. These compact ventilation blowers are available is both
gasoline
driven conviguration and with 115/230V single phase electric motor.
The Positive Pressure Blower is a high volume fan use to pressurize a
burning
structure, in case of fire, in order to force the smoke out. Positive
Pressure
Blowers are portable, gasoline powered fans, most of which utilize a
5.5
horsepower engine. The theory of positive pressure ventilation is based
on
the principal of even pressure distribution. Once a structure is
pressurized,
air and smoke can be forced out through any opening (similar to
escaping
from an inflated baloon).
Electric smoke ejectors (negative pressure ventilation) can be used for
smoke
removal but this has proven to be inferior to positive pressure
ventilation.
What makes Positive Pressure Ventilation superior to negative pressure ?
* The risk of injury from the engaged structure is reduced while
placing
the fan in operation.
* Positive pressure ventilation is faster to set up and requires fewer
personnel.
* The Positive Pressure Blower has a self contained power source, while
electric
fans require cords and adaptors.
* Smoke and heat is removed from all levels of the structure unlike
negative
pressure which can result in localized extraction.
* Quicker results. After initial knockdown, positive pressure
ventilation
can be initiated and will show immediate improvements in the interior
conditions.
* It allows replacement of contaminants with vital cooler, cleaner air
-
especially in sealed or windowless buildings. It's also very effective
in
large and compartmentalized buildings, warehouses, schools, etc.
* Quick results allow firefighters faster entry due to lower heat
levels
and improved visibility.
NISCO Fan Co. has been developing 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.
NISCO 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.
Specific code welding processes and special fan design features are
used
too - to ensure complete gas tight integrity.

Canadian Blower Co. is an engineering distributor of plastic and
fiberglass
fans and blowers for industry applications where aggressive media must
be
moved. Plastic fans include polypropelene, PVC, PVDF, fire retardant
and
UV resistant PPs.
Applications for Corrosion and Chemical Resistant Fans include:
* University, Medical Research, Defence Labs, Fume Hoods OEMs,
Pharmaceutical
Labs
On most campuses there is a certain number of fume hoods that are
used
for various acids testing to break down materials for analysis. HCl and
Perchloric
Acid are the ones used most commonly. Fume hoods and Chemical resistant
fans
are needed.
* High Technology Semiconductors, PCBs, and Photonics
Chip makers use acids to clean metal before they mount thin film
on
the metal upon which they lay circuitry.
* Printed Circuit Board Industry
FRP fans are frequenly used for clean rooms.
* Waste water and Sewage Treatment Plants
Hydrogen Sulfide builds up (H2S) in sewage plant facilities and
causes
an odor problem that has to be treated. Depending on the size of these
stations
corrosion resistant fans are needed. This gas can also be very volatile
and
will require explosion proof motor and static grounding of the fan
housing
by graphite impregnation that Northen Industrial Co. can provide too.
* Salt Air and High Humidity Environments
Any facility near the salt air is also a good place for plastic
fans
and the humidity will eat through metal fans.
* Steel and Wire Manufacturing
As the steel comes in and sits at these plants impurities and
scale
develop on the steel or the wire that needs to be cleaned off before
the
wire or steel can be properly worked with. Acid baths are needed for
this
and the corrosive fumes coming off these aced baths are highly
corrosive...
* Stainless Steel and other Metal Production Facilities
In tha annealing and Pickling process acid baths are used to
strip
scale off the steel after the annealing process that smoothed out grain
patterns
that may have formed during the annealing process. Later on acids are
used
again to support oxidation.
* Chemical and Petrochemical Industries
* Jet Engine and Power Plant Turbine Manufacturing or Servicing
Molted Salt tanks are often used here to descale metals coming
out
of hot furnaces. Pickling and cleaning of titanium which is used in Jet
engine
parts also utilize acid baths as does nickel plating.
* Electroplating and Metal Finishing
These industries use fiberglass fans and fume scrubbers.
* Scrubber OEMs and Designers
FRP fans are standard components in fiberglass srubber designs.
* Industrial Galvanizers
* Printing Press Service Shops
* Chromatography
* Food Processing
Often in the food processing industry they wash equipment down
with
acids and other corrosives. Also they use fans for the humidity that
builds
up from the drying process of foods.
* Pulp and Paper Industry
Pulp and paper manufacturers are very wide users of fiberglass
and
other plastics fans for their boilers, exhaust and filtration systems.
Canadian Blower fans are the finest quality blowers available for
efficient
movement of corrosive, humid, or polluted air, gases, and fumes. These
fire-retardant
and corrosion-resistant plastic fans are specially designed and
especially
suited for hostile applications where coated metal blowers typically
corrode.
Northen Industrial fans are proven thoughout the world and clearly
recognized
for superior quality, reliability, and efficiency.
High-efficiency impellers result in low power consumption, operating
costs,
and quieter operation. All metal hardware is completely sealed from
exposure
to corrosion by incapsulating into FRP or plastic; the steel support
frame
and motor base are powder coated with a corrosion-resistant finish. In
addition
to being highly resistant to chemical corrosion, PP fans are
self-extinguishing
and will not support combustion.
Canadian Blower fiberglass fans housings are manufactured from premium
grade,
fire resistant resins that provide excellent corrosion resistance in
most
chemical environments. Northen Industrial FRP impellers are made of
premium
vinyester that combines corrosion resistance with structural integrity
under
the stress of rotation.
