Performance

	Maximum Air Flow		Maximum air flow is typically rated in cubic feet per minute (CFM).
	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.
	Maximum Static Pressure		Maxim static pressure is typically rated in H20 inches.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.
	Maximum Sound Level		Maximum sound level is usually measured at 3 ft.
	Search Logic:		All matching products will have a value less than or equal to the specified value.

Electrical

	Motor Voltage		Motor voltage is the voltage required to operate the device.
	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.
	Operating Current		Operating current is the current required to operate the device.
	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.
	Nominal Power		Watts (W) are equal to 1 Joule (J) of energy per second. Horse power (HP) is equal to 746 W.
	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.
	Motor Type:
	Your choices are...
	50/60 Hz AC		Motors that operate at 50 to 60 Hz AC include single, multiphase, universal, servo, induction, and gear motors.
	400 Hz AC		Fans and other components that operate at 400 Hz AC are primarily used in aerospace applications.
	DC		DC motors are commonly used in variable speed and torque applications.
	Brushless DC		Brushless DC motors use internal non-contact sensing devices to activate external commutating electronics. Brushless DC motors have armature windings on the stator and the field on the rotor.
	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.

Blower / Fan Configuration

	Blower / Fan Type:
	Your choices are...
	Axial Fan		Axial fans move air parallel to the axis of the fan and provide relatively high flow rates and low pressures.
	Tube Axial Fan		Tube axial fans feature a cylindrical housing with a propeller type fan.
	Vane Axial Fan		Vane axial fans feature a cylindrical housing with an outside diameter of blade tips that fit closely within the housing. This design is highly efficient and provides a high-pressure capacity.
	Centrifugal Blower (Radial)		Centrifugal or radial blowers move air perpendicular to the blower axis and provide relatively low flow rates and high pressures. Air enters around the center of the fan and exits around the outside.
	Crossflow Blower (Tangential)		Crossflow or tangential blowers move air tangential to the axis of the fan and provide relatively high flow rates and low pressures. They are designed for places that cannot fit a standard, high-airflow fan.
	Multistage Blower		Multistage blowers produce very high static pressures at a low flow rate. They are also used to produce a vacuum.
	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.
	Bearings:
	Your choices are...
	Ball / Roller		Ball bearings are used to provide smooth, low friction motion in rotary applications. There are three basic types of ball bearings: radial, angular contact, and thrust.
	Sleeve / Bushing		Sleeve bearings or bushings are used to constrain, guide, or reduce friction. These bearings are also called journal or plain bearings.
	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.

Dimensions

	Thickness:		Thickness is measured along the axis of the fan or blower.
	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.
	Diameter:		Diameter measures the size of the fan blades or blower wheel.
	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.
	Casing / Enclosure Dimension:		The casing or enclosure dimension applies only to ducted or closed devices. This is the maximum area if the device is not square.
	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.

Features & Options

	Features & Options
	Your choices are...
	Locked Rotor Protection		Locked rotor protection prevents motor damage caused by locked rotors at the rated voltage for at least 72 hours.
	Over Temperature Protection		Oven temperature protection automatically turns off the power supply when critical temperatures are exceeded. Power is automatically restored upon recovery to acceptable temperatures.
	Variable Speed / Flow		Devices are designed for variable speed operation.
	Fault Detection		Low speed warning detectors are available for fault detection.
	Integral Controls		Integral controls are mounted on the device.
	IC / PCB Cooling		Devices are designed for integrated circuit (IC) and printed circuit board (PCB) cooling. This includes IC chips.
	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.
