Performance Specifications
   Air Flow Rate       Air flow rate is the rate at which air moves within or between zones. 
   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.
   Static Pressure       Static pressure is the pressure that exists when an equal amount of air is supplied to and exhausted from a space. 
   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.
   Media Temperature       Media temperature is expressed as a range. 
   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 Diameter (Fan or Blower Wheel):       The diameter of the fan, or the diameter or maximum dimension of the blower outlet. 
   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.

Product Form
   Style       
   Your choices are...         
   Forced Draft       Forced draft refers to the movement of air under pressure. Forced draft fans and blowers are so named because they "force" air to move. 
   Induced Draft       Induced draft refers to the movement of air by means of an induced partial vacuum. Induced draft fans and blowers "draw" air. 
   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
   Design Configuration       
   Your choices are...         
   Axial       Axial fans include propeller vans, vane axial fans, and tube axial fans. With these designs, the fan blade circulates parallel to the air flow. 
   Positive Displacement / Rotary Lobe       Positive Displacement (or rotary lobe) fans consist of multiple co-rotating, serpentine shafts that mesh to move air and gases in a controlled manner. The shafts mesh so tightly that backflow is prevented.  Typically, bi-lobal fans and tri-lobal are used to recirculate gases in process equipment when environmental consistency is required. 
   Centrifugal       Centrifugal fans include products with many different blade configurations. Examples include forward curve, backward curve, air foil, backward incline and radial tip. With centrifugal fans, the fan blade rotates perpendicular to the air flow. 
   Crossflow       Crossflow fans draw air from the full radial inlet site of a rotating vane and expel the air on the opposite side through a smaller orifice. Crossflow fans find use where plenum space is small and where a concentrated stream of air is desired. 
   Other       Other unlisted design configurations. 
   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       Direct drive devices directly couple an electric motor to the fan or blower shaft for direct power transmission. 
   Belt Drive       Belt drive fans and blowers are powered by belts and sheaves or pulleys. Typically, one sheave is mounted on an electric motor and the other on the fan or blower. The two sheaves are then 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)      The fan or blower class is a numeric value that describes the device's compliance with requirements from the Air Movement and Control Association (AMCA). Typically, fans and blowers with a larger class number provide greater minimum performance but cost more.
   Your choices are...         
   Class I       Fans and blowers meet Class I AMCA requirements. 
   Class II       Fans and blowers meet Class II AMCA requirements. 
   Class III       Fans and blowers meet 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
           
   Your choices are...         
   Dampers / Louvers       Dampers or louvers are mechanical devices that regulate the volume of air transported by the fan or blower. 
   Explosion Proof       Explosion-proof fans and blowers are designed to withstand the explosion of a specified gas or vapor within the motor housing and/or machine casing. Sometimes, these devices are designated as as TEFC-XP (Totally Enclosed Fan Cooled, Explosion Proof). 
   Inspection / Access Doors       Fans and blowers have mounted doors to provide access to the interior of the fan for maintenance and inspection.  
   Wall / Panel Mount       Wall or panel-mounted fans have mounting brackets or flanges for wall installation or exhaust. 
   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.

Environment
           
   Your choices are...         
   Clean Air / Gas       Fans and blowers are designed for all clean-supply air and exhaust applications. 
   Corrosive Gases       Fans and blowers are designed to handle corrosive gases used in petrochemical plants and chemical processing operations. 
   Dirty Air / Gas       Fans and blowers are designed for heavy industrial air streams, erosive gases, or air streams with particulates. 
   Light Solids / Powder / Dust       Fans and blowers are designed to move granular materials such as grain, pellets, and powders, as well as other particulate matter such as soot, contaminants, and light solids. These fans and blowers are pneumatic. 
   Smoke       Fans and blowers are designed for smoke exhaust. 
   Other       Other unlisted environments.
