Fresh Air Intake Hoods
Titan Air offers different styles of fresh air intake hoods for use with various applications. Intake hoods are typically shipped loose for field installation
45 Degree Hood
This style of intake hood is most commonly used for outdoor mounted, horizontal configuration air handlers. This intake hood has 1 inch by 1 inch bird screen mounted in the hood face to prevent birds and large objects from entering the intake of the air handler. A variation of this type of hood is the hood/filter combination hood. This is a same style hood with the added feature of having cleanable filters mounted in the face of the hood.
Full Turn Down Hood
This style of hood is also used for horizontal configuration units and is commonly used for installations where the air handler intake is facing West or when the intake to the air handler is located high off the ground or roof. This style hood helps keep driving rain or high winds from blowing directly into the unit which can adversely affect the operation of the unit and/or allow rain or snow to get in the building. This hood style is used for either outdoor or indoor mounted air handlers. This intake hood has 1 inch by 1 inch bird screen mounted in the face to prevent birds and large objects from entering the intake of the air handler.
This hood is similar to the 45 degree hood but has the intake air filters built into the hood. This hood style results in lower overall cost and a smaller equipment footprint. Installation labor is also less than installing separate hood and filter banks. Due to the placement of the filters being near the intake, MERV type filters cannot be utilized due to possible moisture damage which leaves cleanable filters as the standard configuration. Also, due to the weight of the Filter Combo Hood, this configuration may not be available on larger equipment sizes. Generally it is limited to use in single blower units.
Vertical or Mushroom Hood
This style of hood is commonly used for indoor mounted, horizontal configuration air handlers where the fresh air must be brought in through the roof versus through a building side wall. This intake hood has 1 inch by 1 inch bird screen mounted in the face to prevent birds and large objects from entering the intake of the air handler. This style of hood typically is mounted on a roof curb.
Intake or Disharge Dampers
Intake or discharge dampers are typically shipped loose for field installation and wiring. There are various options available such as low leak features, special coatings or special construction materials such as stainless steel or aluminum. Ideally discharge dampers should be mounted at least 3 equivalent duct diameters away from the air handler.
There are various types of filters available in a V-bank or flat panel configuration There is a wide range of filters available from low grade cleanable filters all the way up to high efficiency cartridge or bag type filters Some applications require a combination of different efficiencies
When choosing higher efficiency filters, one should seriously consider the use of a backward incline or airfoil fan in place of the standard forward curve fan These specialty fans are recommended so the customer is able to get full use of the filter capacity while maintaining the same CFM level of air delivered. Forward curve fans will experience reduced performance when high efficiency filters load up. Reduced airflow could adversely affect a customer’s operation or process.
It is important for the installer to adequately support all filter sections that are shipped as loose items.
Flat roof curbs are typically shipped unassembled and uninsulated. Standard flat curbs are 18 inches high and are available for all standard unit models. Taller flat curbs, (24” high), are available for TA-109 through TA-230 unit models.
Pitched curbs that are 18 inches high are available for TA-109 through TA-230 model sizes. Taller pitched curbs are not available.
There are numerous options available for discharge diffusers. Discharge diffusers are shipped loose for field installation. The directional blades supplied with each diffuser are to be adjusted at the jobsite to direct the air where needed and then permanently fastened. Ideally diffusers should be mounted at least 3 equivalent duct diameters away from the air handler. It is important for the installer to adequately support each diffuser. Box Type Diffusers are typically used for down discharge, roof top mounted air handlers. Click here to download discharge diffuser information.
Types of diffusers available:
2 Way Diffuser
3 Way Diffuser
4 Way, Box Type Diffuser
Standard VRH Units only require a service platform on the blower section. Consult Titan Air for more information. Service platforms can also incorporate filter access on horizontal units. (Filter section must be attached to AMU). Any INDOOR hanging units must utilize a bottom cradle (by others).
