Air Curtains manufactured by experts !

Air curtains provide a controlled stream of air across a building entrance or doorway to separate interior atmosphere from exterior environment. Air curtain’s airstream prevents cold, hot, or humid outdoor air, as well as insects and dust, from infiltrating the inside the building. This is why Air Curtains are considered as the first line of defense for employee safety.

Although air curtains require power to run the blowers and fan heaters, Air Curtains save much more costs by reducing drive-thru time, window wind fume hazard, providing low-first cost and low total cost as well as additional energy savings in energy battle.

Canada Blower Air Curtain Comstruction typically an air curtain will incorporate double width blower, belt, or direct driven, heating / cooling coils, or a gas fired coil, electrical controls, such as door plunger switch, speed controller, disconnect switch, and others, and mounting accessories, such as mounting brakets for suspended, or verhead mount.

Design Consdierations: To properly design an air curtain application the airstream must hit the floor with enough velocity to create a stable split right at the doorway. Design criteria for selection of proper air curtain for a given application include height and width of the door opening, intended usage, required characteristics of the airflow, which are combination of velocity, volume, and uniformity and the proper balance between each.

Once an air curtain is activated, it creates a split which uses the internal pressure to resist infiltration of temperature, rain, wind, debris, insects, etc. among the conditioned indoors and unconditioned outdoors air.

Typical applications for Canada Blower air-curtains include Commercial various entrances, loading doors, hotels, hospitals, stores, public facilities, and other commercial buildings, and other applications, such as Food service, where all aluminum, or all stainless steel air curtains are utilized .

While Canada Blower air curtains have been commonly used for decades to separate environments in the workplace, perhaps now is the time safety professionals should consider them to help eliminate industrial/commercial doorway accidents as well as keep restaurant drive-thru employees safe from CO poisoning and wintertime temperature extremes.
Typical applications include various entrances, loading doors, hotels, hospitals, stores, public facilities, and other commercial buildings, and other applications.

ILG Canada Blower air curtains are supplied with optional easy mounting trim key.

The American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE) has established a general guideline of 20 cubic feet of outside air per minute/per person for an office environment. This is a sufficient amount of air to dilute building contaminants and maintain a healthy environment. Indoor air quality complaints increase significantly in offices that are not supplied sufficient outside air.

Indoor Air Quality (IAQ) is an increasingly important issue in the work environment. The study of indoor air quality and pollutant levels within office environments is a complex problem. The complexity of studying and measuring the quality of office environments arises from various factors including:

- Building floor plans are frequently changing to accommodate increasingly more employees and reorganization.
- Office buildings frequently undergo building renovations such as installation of new carpet, modular office partitions and free-standing offices, and painting.

Many of the apparent health symptoms are vague and common to both the office and home environment. Guidelines or standards for permissible personal exposure limits to pollutants within office buildings are very limited.

Many times odors are associated with chemical contaminants from inside or outside the office space, or from the building fabric. This is particularly noticeable following building renovation or installation of new carpeting. Out-gassing from such things as paints, adhesives, sealants, office furniture, carpeting, and vinyl wall coverings is the source of a variety of irritant compounds. In most cases, these chemical contaminants can be measured at levels above ambient (normal background) but far below any existing occupational evaluation criteria.

Various building studies indicate that the most likely sources of this problem are - poor ventilation, poor thermal conditions, too high or low humidity, emissions from office machines, copiers and other building contaminants and poor ergonomic layout of workstations.

Air enters office buildings or spaces through both mechanical ventilation systems as well as naturally through leaks around windows, doors, etc. Newer, larger buildings which are highly energy efficient due to sealed windows and heavy insulation primarily depend on mechanical ventilation. Older, small, and low occupancy office buildings can be adequately ventilated through natural sources which include air leakage through opened windows and doors, as well as through cracks in the windows and walls, and other openings.

In a modern office building, the heating ventilation and air conditioning system is designed to keep occupants comfortable and healthy by controlling the amount of outside air that is added to the building atmosphere, filtering both incoming and recirculated air to remove particulates and controlling the temperature. The HVAC system includes all heating, cooling, and ventilation equipment serving a building: furnaces or boilers, chillers, cooling towers, air handling units, exhaust fans, ductwork, filters, steam (or heating water) piping. A ventilation system consists of a blower to move the air, ductwork to deliver air to the room, and vents to distribute the air. A good ventilation design will distribute supply air uniformly to each area and especially areas with office machines. An effectively designed area will not have the supply and exhaust vent too close together because fresh air may be removed before it is adequately distributed throughout the area. Exhaust fans are often located a significant distance away from supply vents. A simple way to determine if the ventilation system is running a vent as a supply or an exhaust is by holding a tissue near the vent.] If the tissue moves, the air is being circulated and the direction the tissue is blown will determine the type of vent.

A ventilation system should provide for a comfortable environment with respect to humidity and temperature. The overall goal of climate control is to provide an environment that is not too cold, hot, dry or humid, and that is free from drafts and odors. Humidity refers to the amount of moisture in the air and extremes in humidification levels can influence how comfortable you may be. When the air is too humid, it makes people feel uncomfortable (wet, clammy) and can promote mold growth. On the other hand, low humidity conditions (which typically occur in the winter months) dry out the nasal and respiratory passages. Low humidity may be associated with an increased susceptibility to upper respiratory infections. Static electricity problems (affecting hair and clothes, particularly synthetic fibers) are good indicators of an office with low relative humidity.
