Application



	Your choices are...
	Clean Air / Gas		Fan / blower designed for all clean supply air and exhaust applications.
	Cooling		The fan's primary function is cooling.
	Corrosive Gases		Fan capable of handling corrosive gases used in petrochemical plants and chemical processing operations.
	Dirty Air / Gas		Fan / blower designed for heavy industrial airstreams, erosive gases or airstreams with particulates.
	Forced Draft		Forced draft refers to the movement of air under pressure. Forced draft fans "force" air.
	Induced Draft		Induced draft refers to the movement of air by means of an induced partial vacuum. Induced draft fans "draw" air.
	Light Solids / Dust		Fan / blower designed for dust collection, grinding-booth exhaust, scrubber exhaust, and other light dust media.
	Material Handling		Material handling fans are used to move bulk solids in material handling applications. A common material handling application is pneumatic conveying.
	Powders		Fan / blower is designed for material handling such as granulated solids and powders.
	Smoke		Fan / blower designed for smoke exhaust.
	Ventilation / Exhaust		The fan's primary function is ventilation or exhausting
	Other		Any other material / gas not covered by the above options.
	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.

Material



	Your choices are...
	Aluminum		The fan is constructed primarily from aluminum.
	Cast Iron		The fan is constructed primarily of cast iron.
	Composite		The fan is constructed primarily from composite materials. Composite materials are often fiber reinforced plastic or fiberglass. Fiberglass is a composite material made by embedding glass fibers in a polymer matrix.
	Plastic / Polymer		The fan is constructed primarily from plastic or polymer.
	Steel		The fan is constructed primarily from steel. Most of the steel produced in the world is carbon steel.
	Stainless Steel		The fan is constructed primarily from stainless steel.
	Other		Other unlisted material of construction.
	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.

Fan / Blower Type


	Fan / Blower Type:
	Your choices are...
	Forward Curved (Centrifugal)		Blades are curved forward in the direction of rotation; requires low speed to move air.
	Airfoil (Centrifugal)		Highly efficient centrifugal blower / fan; name is derived from the shape of blades.
	Backward Inclined (Centrifugal)		Blades are curved backward from the direction of rotation; the blades are flat and of single thickness.
	Radial Blade (Centrifugal)		Typically utilized for material handling (e.g., dusts, light powders etc.) due to blade strength; blades are radial to the fan shaft ("paddle" wheel).
	Radial Tip (Centrifugal)		Similar to radial blade; the blade tips are radial to the fan shaft. The blades themselves gradually slope towards the direction of wheel rotation.
	In-line (Centrifugal)		Cylindrical housing where wheel is generally an airfoil or backward inclined blower / fan.
	Propeller / Panel		Basic propeller type fan design.
	Tubeaxial		Cylindrical housing with propeller type fan.
	Vaneaxial		Cylindrical housing with outside diameter of blade tips fitting closely within housing - typically highly efficient with high-pressure capacity.
	Other		Any unlisted or proprietary configuration.
	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.

	Drive Options:
	Your choices are...
	Direct Drive		Electric motor is coupled directly to fan / blower shaft for direct power transmission.
	Belt Drive		Fan / blower is powered by belts and sheaves or pulleys. Typically one sheave will be mounted on an electric motor and the other on the fan / blower, and the two are connected by belts.
	Search Logic:		Products with the selected attribute will be returned as matches. Leaving or selecting "No Preference" will not limit the search criteria for this question; products with all attribute options will be returned as matches.

	*Fan / Blower Class (if Applicable):*		A numerical description of the class of construction for the fan. There are three classes recognized by the Air Movement and Control Association (AMCA). Typically, the larger the class number, the greater minimum performance and price as well.
	Your choices are...
	Class I		Fan / blower meets Class I AMCA requirements.
	Class II		Fan / blower meets Class II AMCA requirements.
	Class III		Fan / blower meets Class III AMCA requirements.
	Search Logic:		Products with the selected attribute will be returned as matches. Leaving or selecting "No Preference" will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Features


	Explosion Proof?		Motor housing is explosion proof to withstand an explosion of a specified gas or vapor which may occur within it or the housing is designed to prevent the ignition of the specified gas or vapor surrounding the machine by sparks which may occur within the machine casing. Sometimes abbreviated as TEFC-XP (Totally Enclosed Fan Cooled, Explosion Proof).
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

	Dampers / Louvers?		A mechanical device which acts to regulate the volume of air transported by the fan / blower.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

	Inspection / Access Doors?		Door(s) mounted on fan / blower to provide access to the fan interior for maintenance and inspection.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

	Portable / Rolling?		Fan / blower is either small and portable or is part of a movable assembly with wheels, handles etc.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
