![]() Green Building Council) and IECC (International Energy Conservation Code). Are air curtains effective?Ībsolutely! Air curtains have been in the United States for over 65 years and back by many trusted organizations such as ASHRAE (American Society of Heating Refrigeration Air Conditioning Engineers), AMCA (Air Movement & Control Association), USGBC (U.S. MARS LoPro 2 (LPV2), Quiet Pro (QP10 ), Standard 2 (STD2), Phantom (PH10) Series.īERNER Commercial Low Profile (CLC08), Architectural Low Profile (ALC08), Commercial High Performance (CHD10), Architectural High Performance (AHD10), Architectural Recessed 12 (ARD12) Series. Here is a list of series that work well in a residential setting: Exposure to noise louder that the Environmental Protection Agency (EPA) safe noise level of 70 dB over 24 hours will damage hearing. The National Institute of Occupational Safety (NIOSH) states that for a 115 decibel (dBA) sound, the exposure is just 28 seconds. What is dBA?Ī decibel (dB) is a unit of measurement for sound, A-weighted decibels, abbreviated dBA, are an expression of the relative loudness of sounds in air as perceived by our ears. The Mars LoPro Series 36” is only 53 decibel (dBA). Here is a list of units that are extremely quiet. ![]() The good news is that Air Door Distributors sells units that are super quiet for residential applications. Some air curtains can be perceived as noisy especially in back door restaurant applications as these units need to be extremely powerful to ward off flying insects into kitchen areas. In this lower setting, making sure that air hits the floor is creating the seal needed. Simply dial up for insect control when needed and dial down for temperature control. Insect control does require more air flow then just just temperature control and that is why we suggest using a variable speed control. Again, the downward force of the air creates a seal from contaminants from entering. Unheated air curtains are perfect for those who are using the air curtains for summer months for insect control and temperature control over open doorways. We add either Electric, steam or hot water coils to the air curtain to create comfort and a secondary heat source. Whenever we move air across the body, this is called wind chill which makes the air feel colder than it actually is. Heated air curtains also known as heat curtains are ideal for those who are concerned primarily for temperature control. The difference with air curtains is that they concentrate air downward to create an invisible shield between spaces. How do air curtains work?Īir curtains are similar to fans in that they generate a controlled stream of air.
