Powered Aire's Food Service commercial line of air curtains is ideal for restaurant customer entrances,school cafeterias, bars, concession trailers, dumpster areas, walk in coolers and countless other applications. They are constructed of stainless steel with a black intake screen and beveled edges for an aesthetically pleasing look. All commercial units are similar, so if several models are used in conjunction with one another at several openings, the building will maintain a certain symmetry. Most models are available with several heating options, including electric heat, (natural gas, hot water and steam available by contacting the factory).

What’s an Air Curtain?


Air curtains create a laminar airflow that is projected over the opening of a doorway. This "curtain" of air acts as an invisible barrier that won't let air flow through it. Conditioned air from the inside of the door that would normally escape when the door is opened is instead diverted back inside when it hits the wall of air. The air seal also keeps the outside air from entering. This can be beneficial for several reasons, including lowering heating and cooling costs, stopping insects from entering, and keeping airborne particles and contaminants out of a particular area.

An aire curtain is most often used to separate one environment from another. It does this by creating a "curtain" of moving air that is projected over the opening of a doorway. The wall of air acts as an invisible barrier that will not allow air to flow through it. Typically, the aire curtain is mounted over a doorway on the inside, as a result, the air pulled into the intake of the unit is from the conditioned environment. This air is accelerated and forced through a narrow discharge along the length of the aire curtain creating a laminar airflow. The discharge angle can be adjusted using the provided turning vanes to achieve optimum performance. As the discharge angle increases, the air has to travel further until it hits the floor. Since the velocity of the air decreases as it gets further away from the aire curtain, if the discharge angle is too large the aire curtain won't be able to stop much wind from entering near the floor. If the discharge angle is too small, the air leaving the unit will not have enough horizontal force to stop a significant gust of wind from entering. Usually the ideal discharge angle for maximum wind-stopping capability is around fifteen degrees.

When the discharged air reaches the floor it splits, forcing some air outward and some inward. This is why when a unit is used for climate control, it should be placed on the opposite side of the doorway from that of the air that is to be kept out. For example, if it is winter and you are trying to keep cold outside air from entering a building, the aire curtain would be placed on the inside so that it is blowing warm air. When the warm air hits the floor, some is leaked to the outside and some is blown back inside. If the unit was on the other side of the opening, some of the cold air that you are trying to keep out would be blown inside, defeating the purpose. If the unit is to be used for insect control, the aire curtain can be mounted on the outside of the doorway as long as the discharge is adjusted so the air is blowing back toward the outside. In this situation it doesn't matter if some of the outside air is blown inside after it splits at the floor. This air should already be free of insects because they will not fit through the intake screen.

Typical Food Service Applications

Food Service Entrances - Satisfy Local Health Codes - Our (RBT) Restaurant Bug Tested Model is ETL Sanitation Listed for Standard NSF37. With the RBT air curtain mounted seven feet above the finished floor, it will keep insects, dust and other debris from entering the sanitary environment through doors. These units are ETL listed for indoor/outdoor operation.

Restaurant Entrance - With the heavy flow of traffic in and out of casinos, banks, health spas, and bars maintaining the conditioned air and providing customer comfort are major concerns. Our Restaurant Customer Entrance aire curtains, when placed above entry doors, will prevent conditioned inside air from escaping and extreme hot or cold outside air from entering. In turn this will provide substantial energy cost savings and provide unparalleled customer comfort.

Recess Mount- Restaurant Entrances - Often, due to obstructions and aesthetics, aire curtains are mounted above the ceiling tile. Powered Aire can supply a nozzle extension to keep the air uniform until it passes through a linear slot diffuser (supplied by others). An architecturally pleasing return air grille (supplied by others) is utilized to allow the aire curtain to draw the conditioned air from the space and allow access to the unit for maintenance.

Restaurant Drive Thru Windows - The Restaurant Mini Power Series is often used on restaurant drive thru windows. While the door is open and closed continuously, the aire curtain prevents exhaust fumes, insects and hot or cold air from entering the building while at the same time preventing conditioned indoor air from escaping.

Bakeries/Rising Rooms - Tamperproof aire curtains are often supplied to bakery facilities for use on doors in areas where sanitary conditions are a concern.

Dairy Operations - Aire curtains are used in dairy operations to prevent insects and other contaminants from entering the sanitary processing areas through doors.

Restaurant Delivery Doors - The Restaurant Bug Control Series is often used above the restaurant's back delivery door. The unit is mounted above the door on the outside of the building to prevent insects and odors from entering the building. These units are rated for outside operation.

Open Boardwalk Restaurants/Shops - The Restaurant Bug Control Series is often used on boardwalk's restaurants. The aire curtains allow the doors to be left open, which will attract business, without letting bugs and unconditioned air enter the establishment.

Zoos & Amusement Parks - Our low profile food service unit can be mounted above concession stand windows at zoo, amusement parks, and food court trailers to prevent insects from entering the buildings and contaminating food products. The aire curtain will also keep conditioned air inside and non-conditioned air outside.

Trash Compactors - Powered Aire's aire doors are effective at containing foul odors. For example, four air curtains can be placed in a box formation above a trash compactor in an open area and the odors will not leak to other parts of the facility.

Advantages

SPECIAL PLENUM DESIGN
RCE, RBE, RIT, RCC, & RBT

The use of plenums in our aire curtains makes the air flowing out of the discharge more uniform across the entire length of the nozzle. Most of our competitors aim the discharge of each blower directly down and the air flows right out of the nozzle. These blowers cannot be placed directly beside each other since the return air enters from the sides. There are also motors in between the blowers spreading them out further. When the blowers force air directly out of the discharge of the air curtain, there will be dead spots wherever there are spaces between the blowers.
In Powered Aire's units, the air coming out of the blowers is pointed toward the back of the aire curtain. Here it fills a specially designed plenum. When the plenum is pressurized, the air is then forced out evenly across the entire length of the plenum discharge.

Another benefit of this design is a reduction in the noise level. Some of the noise generated by the turbulent air being discharged from the blowers that can be heard in our competitors' models is absorbed by the plenum. The air discharged from the plenum is more evenly dispersed across a larger cross-section, drastically lowering the sound pressure levels.

STAINLESS STEEL AND COMPETITIVELY PRICED
RMP, RCE, RBE, RIT, RCC, & RBT

Another advantage of using Powered Aire air doors is that every aire curtain we manufacture is constructed of stainless steel. We still remain competitive with other manufacturers who make their units out of plastics, painted steel, or aluminum by avoiding costs associated with expensive molds, disposing of chemicals, maintaining a paint booth, extra labor, and being environmentally friendly. Along with being corrosion resistant, stainless steel also gives our air doors an aesthetically pleasing look. The reflective properties of the metal allow our aire curtains to blend in with the architecture by mirroring the color of their surroundings.

NO EXTERNAL MOUNTING HARDWARE
RMP, RCE, RBE, RIT, RCC, & RBT

Another advantage of Powered Aire aire curtains is the way our units are mounted. Each unit comes with integral top and wall mounts so that for standard installations no external hardware needs to be installed or purchased.
