Dust Collectors and Dust Collector Filters Specifications

Help with Dust Collectors and Dust Collector Filters specifications:

Collector Unit

	Filter Only
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
	Collector Type
	Your choices are...
	Ambient		Ambient units are free-hanging systems for use when applications limit the use of source-capture arms or ductwork.
	Collection Booth		Collector booths require no ductwork, and allow the worker great freedom of movement. They are often portable.
	Downdraft Table		A downdraft table is a self-contained portable filtration system that removes harmful particulates and returns filtered air back into the facility, requiring no external ventilation.
	Source Collector / Portable		Portable units for collecting dust, mist, fumes or smoke at the source.
	Stationary		Stationary collectors, such as a baghouse.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Filtration / Separation Technology

	Process
	Your choices are...
	Dry		Dry-type air pollution control systems rely on absorption for removal or neutralization of gases that may be corrosive, poisonous or otherwise deleterious to the environment.
	Wet		Wet-type pollution control systems incorporate liquids - often water - into the process either by forcing the processed gases through a bath or by addition to the gaseous stream.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
	Separation / Filtration System		Systems for fine removal may only contain a single filtration system, such as a filter bag or cartridge. However, most units utilize a primary and secondary separation and filtration system.  Furthermore, some units may have third and fourth-stage filtration. All separation and filtration systems used within the unit should be specified.
	Your choices are...
	Bag-type Units (Baghouse)		A baghouse is an air pollution abatement device used to trap particulate by filtering gas streams through large fabric bags typically made of glass fibers or fabric.
	Cartridge-type Units		Filter cartridges are made out of a variety of synthetic fibers and  collect sub-micronic particles without creating an excessive pressure drop in the system. Filter cartridges require periodic cleaning.
	Cyclone (Centrifugal) Separators		A cyclone separator is an apparatus for the separation of fine particles suspended in air or gas by centrifugal means.
	Electrostatic Precipitators		Electrostatic precipitators are a type of air cleaner, which charges particles of dust by passing dust-laden air through a strong (e.g., 50-100 kV) electrostatic field. This causes the particles to be attracted to oppositely charged plates so that they can be removed from the airstream.
	Impinger System		Impinger systems are a device in which particles are removed by impacting the aerosol particles of a liquid.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
	Collector Filter Cleaning
	Your choices are...
	Automatic Shaking (Vibrating)		Automatic (e.g., continuous or timed) shaking action provides a back and forth motion. The shaking action aids separation by spreading the material around the filter or bouncing the material.
	Manual Shaking		Manual shaking action provides a back and forth motion. The shaking action aids separation by spreading the material around the filter or bouncing the material.
	Pulse-jet		Pulse-jet blasts of air dislodge particles and clean the filter.
	Reverse Air		In the reverse-air technique, air is blown back through the filter material to remove dust. The compartment must be periodically shut down for the cleaning technique to remove the material from the surface of the fabric filters.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Performance Specifications

	Efficiency		The efficiency with which the filter system controls or eliminates contaminants.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Minimum Particle Size Filtered		The minimum particle size that units are capable of filtering.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Airflow		Airflow is the velocity of the air stream created.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Applications and Features

	Applications
	Your choices are...
	Abrasives		Abrasives are substances for grinding, honing, lapping, superfinishing, polishing, abrasive blast cleaning, pressure blasting, peening or barrel finishing. Abrasives include natural materials such as broken up nutshells, sand, garnet, emery, corundum and diamonds, and electric furnace products like aluminum oxide, silicon carbide, and boron carbide, as well as glass and various metallic abrasives.
	Cleanroom		The unit is designed specifically for cleanroom applications.  Most cleanroom vacuums will be equipped with a HEPA filter or better.
	Coolant / Oil Mist		Units are capable of filtering coolant smoke and mist from metal finishing and forming processes, and machining oil mists.
	Explosive Media		The unit is capable of filtering explosive dusts, mists or fumes.
	Fine Powders		Fine powders can include carbon black, talc, pigments, oxides and plastic compounding dusts.
	General Cleaning		The unit is designed for general cleaning applications.
	Non-free Flowing		Collection of non-flowing or sticky powders and dusts.
	Metalworking Chips / Fluids		Collecting metal scraps poses a potential health hazard to fabricated metal workers due to the oils, lubricants and coolants that must be collected with the metal. Once picked up by an industrial vacuum cleaner, these metalworking fluids (MWFs) emit harmful aerosols that may contaminate the working environment, damage nearby equipment and make floors slippery.
	Reclaim / Recycle		The unit is designed to reclaim, recycle or recover materials for reuse.
	Toxic Media		The unit is capable of filtering toxic materials such as dust, mist, fume or smoke from the air.
	Welding Fumes		The unit is designed specifically for the collection of welding fumes or dust; these may include flux recovery systems.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
	Features
	Your choices are...
	Continuous Duty		Continuous duty units are rated for 100% duty cycle (i.e., constant use).
	HEPA / ULPA Filters		High-efficiency particulate air (HEPA) filters are replaceable, extended-media, dry-type filters in a rigid frame with a minimum particle collective efficiency of 99.97% for a 0.3 micron particle, and a maximum clean filter pressure drop of 2.54 cm (1 in) water gauge when tested at rated air flow capacity. Ultra-low penetration air (ULPA) filters are extended media dry filters in a rigid frame that have a minimum particle collection efficiency of 99.999 percent for particles greater than or equal to .12 micron in size.
	Instrument Panel		The unit is equipped with an instrument panel for user operation.  The instrument panel may be equipped with an alphanumeric keypad, gauges, safety switches, on-off switches or timer controls.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
