Effective attic ventilation is critical for a long-lasting roof yet most homes have inadequate attic ventilation. Master Flow's SRV1 provides increased airflow over typical ridge vents, turbines and roof louvers to help reduce hot or moist air in your attic. They also eliminate electric costs by running off the sun's energy (when it is needed most). When the sun is not out, it reverts to a typical static ridge vent. You can maintain the beauty of your roof by incorporating the superior look of a shingle-over ridge vent and remove the expense and hassle of scheduling electricians.

  • Vents your attic 750 cfm for excellent airflow. Up to 25 times more airflow than typical stand-alone ridge vents and comparable to typical power vents
  • Improves your ventilation system more effectively than (and a great replacement for) roof louvers or turbine style vents
  • No-hassle operation with no extra wiring or expensive, hard-to-schedule electricians needed.
  • Low cooling costs, solar powered to reduce related energy costs
  • Provides superior aesthetics versus power roof vents (electric and current solar), turbines and roof louvers. The low-profile solar panels virtually blend into your ridge line
  • Thermostat control allows the unit to switch from a typical ridge vent to a solar powered vent for increased airflow when you need it most
  • Adjustable solar panel with tilt design for optimal solar exposure
  • Impact resistant solar panels tested to withstand hail and foreign object impact for long-lasting operation
  • Peace of mind backed by 5 year ltd. warranty with 2 year labor protection from GAF, North America’s largest roofing and ventilation manufacturer
  • ETL Approved

I have numerous large rectangular soffit vents. This unit looks like it could easily be adapted to install into one of the rectangular soffit vents. Can it? If not, is there a similar item than can be?

No, this item is designed to be installed into and in conjunction with an existing ridge vent. It will not fit in an existing roof louver opening. Please call Technical Services at 800-211-9612, M-F 8A-5P EDT, for assistance with any additional questions.

The fan installs inside the attic but additional roof decking will have to be cut. Please place this link in your browser to get the installation instructions. Please call Technical Services at 800-211-9612, M-F 8A-5P EDT with any additional questions.

Rated 4.0 out of 5 by 1 reviewer.
Rated 4.0 out of 5.0 by Interesting Solution to Widely suggested Roof System equipment. I'll start with the quality downgrade. I ordered 5 units for a 4000 sq/ft roof. One of the five was damaged with the axel having come off the spindle on the non-motor side. A second unit had a damaged bracket that made panel install not possible. The potential for worry free operation is there but I do not recommend installing the solar panels to the ridge caps anywhere that hurricanes, tornados, or winds over 60mph can be a factor. GAF has NOT wind tested the installation. So a firm and waterproof install to the roof deck is a consideration. I think the bracket attach points for the panels are the weak points for the system. Riveted nuts are attached the steel bracket that a thumb screw is placed through the aluminum frame of the panel. Add that the hole is drilled to close to the edge of of the frame and you can see this is an obvious failure point in high wind. So I suggest a sturdy install of the panel bracket to the roof deck with the hinges on the up hill side for panel tilt. Also, remember to consider cross bracing under the roof deck before selecting placement of the fan itself. There is plenty of wire so the fan and panels do not have to be closely located. Prior to installation with ridge caps sealed, the attic max temp on a 92F day was 140F. After install, but not operating max temp was 125F. Only four of the five are operating (waiting for replacement) and one has the panels installed on the wrong side (east not west). With this the max temp still has gotten to 125F still(no difference). I'm witholding a five star rating for the max temp dropping when all fans are installed correctly. June 24, 2014
