Air Circulator

A unit that creates air movement within a given space.


The Air Movement and Control Association International, Inc. is a not-for-profit international association of the world’s manufacturers of related air system equipment – primarily, but not limited to: fans, louvers, dampers, air curtains, airflow measurement stations, acoustic attenuators, and other air system components for the industrial, commercial and residential markets.


Unit of measurement that expresses the strength of current of electricity.


ASHRAE 62.2 is a minimum national standard that provides methods for achieving acceptable indoor air quality in typical residences. The standard has three main components: Whole House Ventilation, Local Exhaust, and Source Control. The recommendations that follow are for most common conditions, extreme conditions require additional consideration. To learn more click here.

Blower Wheel

Also referred to as the fan blade. Spins to generate ventilation power within the unit.


British Thermal Unit. Unit of measure of heat transfer.

California Title 24

“The Energy Efficiency Standards for Residential and Nonresidential Buildings were established in 1978 in response to a legislative mandate to reduce California’s energy consumption. The standards are updated periodically to allow consideration and possible incorporation of new energy efficiency technologies and methods.” As it pertains to ventilation, it provides minimum standards for the performance of the products that may be used, especially when a light combination unit is to be a part of the installation.


Cubic Feet per Minute. Unit of measure for how much air is exchanged in one minute of time.

Charcoal Filter

Filter used to eliminate odor from the air passing through it. Needed is cases where air will be recirculated back into the living area.

Combination Filter

Filter that combines a grease filter and a charcoal filter in one.

Contractor Pack / Project Pack

Method for packing a fan for Contractor installation. First package contains the “housing” or “can” portion while the second package contains the “MBG” (motor/blade/grill) or “trim” portion.


Offers a choice of ducting options within the same unit. Most Air King convertible fans can be ducted either vertically, horizontally, or ductless.


Underwriters Laboratory. UL is the trusted source across the globe for product compliance. Benefiting a range of customers – from manufacturers and retailers to consumers and regulating bodies – we’ve tested products for public safety for more than a century.

dB A

Unit for expressing the relative intensity of sounds on a scale from zero for the average least perceptible sound to about 130 for the average pain level.


Method of ventilation that draws air into the unit, filters it and recirculates it back into the room.

Duct free / Ductless

A unit that recirculates the air back into the living area. Generally some type of odor filter is needed to operate. No duct work is needed with a unit that is ductless.


A government-backed program helping businesses and individuals protect the environment through superior energy efficiency.

ETL – Intertek

ETL (Electrical Testing Laboratories) was founded by Thomas Edison in 1896 and in their words, “Intertek provides quality and safety services to businesses across the globe. We help our customers improve their products, assets and processes to make them more successful in their chosen markets”.


Energy efficient lighting option.

Fusible Link

Used in the Air King Ceiling Radiant Dampers, the fusible link is two pieces of metal joined together that will release when the temperature reaches 212°, breaking the link and allowing the curtain to seal off the ducting.

GFCI Circuit

Ground Fault Circuit Interrupter. Switch utilized for high voltage electrical shock protection.

Grease Filter

Filter used to catch grease and other contaminates from entering the unit. Most commonly used with range hoods.

Hanging Brackets

Used to mount certain Air King exhaust fans. They attach from one ceiling joist to another ceiling joist and allow the installer to position the exhaust fan between them.

Horizontal Exhaust

Exhaust that enters into the duct work on the horizontal plane (out the side or the back of a unit).


The Home Ventilating Institute – HVI – is a non-profit association of the manufacturers of home ventilating products. HVI offers a variety of services including, but not limited to – test standards, certification programs for airflow, sound, energy performance for heat recovery ventilators, market support and three annual meetings to discuss common industry issues. Through a Certified Ratings Program, HVI provides a voluntary means for the residential ventilation manufacturers to report comparable and creditable product performance information based upon uniformly applied testing standards and procedures performed by independent laboratories. Together these activities help to promote the health and growth of the home ventilation while providing consumers with valuable information and confidence in their choices.


Common household lighting option.

Infinite Speed Control

Controls the speed of the motor. The user has the ability to set the unit at any desired speed level.

Keyhole Slots

Mounting system for installing units where the mounting screws or nails can be put into place and then the unit is lifted over the screws and slid into place.


The mission of the international nonprofit NFPA is to reduce the worldwide burden of fire and other hazards on the quality of life by providing and advocating scientifically-based consensus codes and standards, research, training, and education. Established in 1896, NFPA serves as the world’s leading advocate of fire prevention and is an authoritative source on public safety. In fact, NFPA’s 300 codes and standards influence every building, process, service, design, and installation in the United States, as well as many of those used in other countries. NFPA’s focus on true consensus has helped the association’s code-development process earn accreditation from the American National Standards Institute (ANSI).


Low wattage light feature. Air King products that have this feature utilize either a 4 Watt or 7 Watt bulb.


When used in the description of an Air King Air Circulator, it is the ability of the fan’s head to move from side to side providing a larger coverage area.
