Applications
Back to Top
|
| ||
| Your choices are... | |||
| Air Handling Units / HVAC | Air Handling Units and HVAC (Heating, Ventilating and Air Conditioning) systems incorporate fans, such as plenum fans and duct fans, to move air in buildings and enclosed environments. | ||
| Exhaust Ventilation | Exhaust fans draw air out of a building or workspace that may be contaminated with smoke, noxious gases, fumes, and other undesirable components. | ||
| Materials Handling / Pneumatics | Material handling and pneumatic systems contain fans used to propel granular materials such as plastic resin pellets, grains, and powders. Such systems move these materials between storage containers and to production equipment. | ||
| Personnel (Mancooler, Box Fans, etc.) | Fans for personnel and workspace use, such as Mancoolers, box fans and pedestal fans, are especially advantageous where a welcome draft of air is required to give comfort to personnel in hot locations. | ||
| Pressure / Pressurization Blower | Pressure blowers (or pressurization blowers) are used in applications, such as positive pressure building (where entry of outside air or dust is detrimental) and cleaning drying equipment, where a positive pressure is required downstream from the fan. Typically, the blower resides in an enclosure designed to give a common mounting platform for a blower and its electric motor. The enclosure can be mounted on vibration isolators and maybe referred to as a unitary base or vibration isolation base. | ||
| Product / Process Cooling | Process cooling fans are designed for use in large scale industrial process equipment such as heat exchangers, cooling towers, process dryers, and where high throughput over long durations in challenging environments is required. | ||
| Other | Other unlisted or specialty mounting arrangement. | ||

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. | ||

| ||
| 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. | ||

| ||
| System | |||
| Your choices are... | |||
| Bare (No Motor, Controls) | Bare fans and blowers consist of products that include items such as fan blades, bearings, mountings, and enclosures. Bare fans and blowers require a power system, such as an electric motor, and a user-provided control system. | ||
| Packaged (Complete System) | Packaged fans and blowers are fully-functional products that only require electricity or a similar power resource for operation. | ||

| |||
| 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. | ||

| |||
| 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. | ||
