Cyclone Dust Collectors for Air Cleaning
Canadian Air Systems Co. is an engineering company for dust collecting systems. Dust collection equipment is available in numerous designs utilizing a number of principles and featuring wide variation in effectiveness, initial cost, operating and maintenance expense, space, arrangements and material of construction.
The following factors determine selection of dust collection equipment:
* Concentration and particle size of contaminant;
* Degree of collection required;
* Characteristics of air or gas stream;
* Characteristics of contaminant;
* Methods of disposal.
Depenging on above factors, the following Canadian Air Systems dry type dust collectors can be utilized:
- Cyclone Dust Collectros
Cyclone Collectors are frequently applied for the removal of coarse dusts from an air stream, as a pre-cleaner to more efficient dry or wet dust collectors and / or as a separator in product conveying systems using an air stream to transport material. Principle advantages are low cost, low maintenance and low pressure drop (in order 0.75" to 1.5" WG), but this type dust collector can not be used for collection of fine particles.
- High Efficiency Centrifugal Collectors
Have been developed whereby higher centrifugal forces are exerted on dust particles in a gas stream. Improvement in dust separation efficiency has been obtained by 1) increasing velocities through a cyclone shape dust collector, 2) utilizing a skimmer or other design feature, 3) using a number of small diameter cyclones in parallel and 4) placing units in series in some unusual applications.
- Dry Type Dynamic Precipitators
In this collector, dust is precipitated by centrifugal force on to specially shaped blades on an exhauster wheel and then conveyed through a dust circuit in the fan casing to the dust storage hopper.
- Louver Type Dust Collectors
Centrifugal forces can be applied to a particle by a rapid change in direction of air flow by series of plates set at an angle to the air stream. Coarse particles traverse the air stream and will project back to the dirty air side by the forces that can be produced from such an impact.
- Settling Chambers
Dust is ettled out in a large chamber when conveying velocities are reduced to the point where the particles are no longer conveyed. Extreme space requirements and the presence of edde currents to nullify the effective velocity mean that settling chamber type of dust collectors can be used only for removal of extremely coarse particles.
- Potable Unit Collectors
To fill the need for dust collection from isolated, portable or frequently relocated dust producing operations, a number of unit collector designs are availbale having capacities in the range of 200 to 1,000 CFM. Featuring small space and designed to recirculate the air, collectors of this type have been used extensively, especially in the metal working industry.
A stationary Cyclone Type Dust Collector is one of the most popular choices for industrial users due to it low initial cost and simple maintenance.
Cyclone dust collector provides a simple and economical means to most medium to coarse dust collection applications. The centrifugal action and gravitational forces are the basic plinciples of its operatrion. The dust laden air enters the dust collector through ahigh velocity inlet forcing the dust particles to the collector wall in spiral motion. This, together with gravitational pull, forces the concentrated dust downward and out of the dust outlet, while the cleaned air travels upward via the inner vortex and out the air outlet on the top side of the dust collector.
For abrasive or corrosive applications, special cmaterials of construction are available, such as abrasion resistant carbon steel, stainless steel, special alloys, rubber liners, etc... Many sizes and arrangements of cyclone dust collectors are available from Canadian Air Systems to meet specific capacities and space requirements.

Did Billy Bishop establish a Canadian Air Force?
I am doing an essay for World War 1, and I was wondering if he was the person who established the Canadian Air Force.
