Tamarack HV1600-GR
The Tamarack HV1600-GR is a two-speed whole house fan. The HV1600-GR utilizes two speed fan motors
to minimize power consumption. The system has an automatic, motorized dual door assembly, providing an air tight seal.
It delivers up to 1600 CFM (Cubic Feet of air per Minute)
Key Features
Two-speed operation

At high-speed, you get 1600 CFM to cool your house down fast. At low speed, our unique design provides 900 CFM.
Energy efficiency
On high speed, the Tamarack HV1600-GR uses 276 watts of power — a small fraction of the energy used by an A/C compressor.
The Tamarack HV1600 whole house fan qualifies for rebates in a growing number of states and municipalities. Please check
with your local utility for more information and our rebates section for a listing.
Automatic insulating doors
A key drawback with traditional whole house fans was air leakage between the attic and living spaces. This could result
in dirty attic air entering your home, and, in cold climates, warm, and moist indoor air entering the attic and causing
water damage through condensation. Properly installed, the Tamarack HV1600-GR takes care of this problem with automatic,
insulated doors that seal tight when the fan is not in use. So attic air NEVER leaks into your living space, and warm air
never condenses in your attic. And you can just relax and not think about it.
Premium Cube Core grill
The Tamarack HV1600-GR comes with a premium high-flow grill that minimizes air movement noise through the grill. These
high-performance grills look great too, so your system looks as unobtrusive as it sounds.
Maintenance-free operation
The Tamarack HV1600-GR requires no maintenance and never requires lubrication.
3-year warranty backed by professional support
Not only are the units guaranteed for 3 years, but they’re backed by our professional technical support. If you have a
problem with your unit — or just a question — you’ll get prompt, knowledgeable responses. Guaranteed.
