This whole house fan HV-1600GDR has two speed settings, low/high. On low the unit performs like an HV1000 with an average of 1150 cfm of air flow at its opening.  On high the HV1600 does 1600 cfm of air flow.
Unlike other systems, the HV series requires no maintenance. The fan motors of the HV1600 are of extremely high quality and are built to last.

The HV series of whole house fans are insulated and when not in use form an air tight seal between your attic and living space. There is no other unit available that boasts these levels of insulation and protection. Fan housing is now black as shown in main product picture.

As an additional quality control method, every single unit is tested and run at the factory for 24 hours prior to shipping, a commitment to excellence. 

HV1600 2 Speed Specification Sheet - Click Here To View Grille: The HV system includes a 24" x 14" white return air grille. The outside diameter of the grille measures 25 3/4" x 15 3/4". The rough opening of the grille measures 23 1/4" x 13 7/8". Controls: The HV1600 2 Speed comes standard with RF remote controls, which has a range of approximately 30'.

Wiring The HV1600-GDR:

As of 12/2005 - All HV1600 fans have a line cord for ease of installation. Simply plug it in and the fan will work with the included handheld remote control. The dedicated remote control system offers the user a simplified 110 volt powered remote control. The system includes a hand-held transmitter, which operates on a 12-volt battery (included), a receiver which has been built into the fan. The transmitter features a signal operating light that goes on when the ON or OFF buttons are depressed. The controls offer 256 unique security codes that are factory programmed into the system allowing multiple remote control units in the same room or building. The systems operating distance is 30' and is not restricted to "line-of-sight" applications because the system uses radio frequency control. It operates on the R.F. frequency of 303.875 MHz. The control is UL listed and is FCC certified in the U.S. and I.S.C. certified in Canada.

Important Facts To Consider When Sizing A Whole House Fan:

If you have done any research on whole house fans you will see a lot of sites that recommend multiplying your homes total square footage by three and that will tell you what size whole house fan you would need in air flow (CFM). Yes, that formula will work, but it is very inefficient and many times impractical. In the case of whole house ventilation for cooling purposes, bigger is not necessarily better.

In order for the whole house fan to operate efficiently and effectively, consider the below variables:

1. Fan size
3. Intake air source
4. Attic exhaust vent requirements
5. Climate differentials and peak summertime temperatures

Fan Size:

The bigger the fan the faster it will cool your home?  Not necessarily. After the first few air exchanges, the value of having a large air flow is diminished.  Yes, the air flowing into your home will be cooler, but your house will not. A home that has been in a hot environment throughout the day actually stores and retains heat. The effects of the heat permeates throughout the entire home, especially in the attic. Cooling the home is best accomplished by having a constant and continuous flow of cooler air over a longer period of time, to effectively dissipate the stored heat. A lower flow of cool air is very effective at removing the stored heat in your home.

Intake Air Source & Exhaust Requirements:

In order for cooler outside air to enter the home you must open a minimum amount of windows or doors to allow the cooler air to flow into your home. On the same note and this is very important, you must have an adequate amount of exhaust vents to allow the air pulled into your home to exhaust the warm air outside. A good rule of thumb to use is for every 1000 cfm of airflow, you need 1.3 square feet of unobstructed roof venting or 1.33 sq. ft. of net free venting.

Net Free Area Defined: For every 750 cfm of airflow, it is recommended that there be a minimum of 1.33 sq. ft. of attic venting, i.e. roof vents, gable vents, soffit vents, ridge vent. This will allow the air flow of the fan's exhaust air into the attic the ability to flow out of the home freely.   To calculate your net free area: - Count and add up your total number of vents in feet. If your vent(s) are screened take approx. 1/2 away from your total.

For example: You have four 1 sq. ft vents, and they are screened. You would have a 4 sq ft gross of venting, however since the screens will block air flow, you would need to subtract approximately 2 sq. ft of venting from your gross, giving you a 2 sq. ft net free area. Warranty: The unit comes standard with a 3 year limited warranty.

Climate Differentials & Peak Summertime Temperatures:
A whole house fan works best when evening and outside temperatures are cooler than interior temperatures.  Remember, a whole house fan brings in the outside air.  You would never run a whole house fan during the day when outside temperatures are at their highest.  A whole house fan is not air conditioning, the air it brings into your home, is only as cool as the outside air temperature.  Depending on what your average peak summertime temperatures are at, will determine what size whole house fan to purchase. 

What A Whole House Fan Is Not:  You may be concerned about indoor air quality, and that is a growing concern among modern day tightly built homes.  However, a whole house fan, is designed for one purpose - to remove heat from the home.  A whole house fan, should never be used for ventilating a tight home.  Continuous Whole House Ventilation should be accomplished with a Heat Recovery Ventilator/Energy Recovery Ventilator HRV/ERV, these devices exchange the air in a home at about .35 air exchanges per hour. They are designed to allow a balanced flow of air through the home, by allowing make up air into the home.

A properly sized and balanced whole house fan, is an effective way to cool your home and very efficient at reducing A/C costs which is associated with higher utility bills during the spring, fall and especially summer months. The whole house fans we have are the best in the industry, featuring easy installation, quiet operation, and insulated air tight sealed doors when the unit is not in operation.
