Designed for sloped roof installations on composite shingle or flat roof material. Roof slope should be such that the potential for standing or pooling water is not considered a potential problem. Surface mount models designed for most standard sloped roofs with regular or dimensional shingles.

Slim profile, 7-1/2” high, square design blends in well with angular pattern of shingles. Heavy gauge stainless steel bird and insect screen provides maximum protection from insects and animals without impeding air flow. Specially designed one-piece, 12” aluminum 5-blade fan is pitched for maximum airflow and operates whisper-quiet with no harmonic noise.

SDF-20SF-R (Remote Panel Mount)
Solar Attic Fan The Remote mount is a two-piece unit connected via a wire. It is designed so that the ventilation fan can be installed in a location that is either less visible, more convenient to reach from the roof-side, or more accessible from the attic, while the flat profile solar panel is mounted where it will receive the best opportunity for direct sunlight. Kit includes 15 of wire, but up to 50 can be added if required. AVAILABLE IN SEFL FLASH OR CURB MOUNT MODELS

SDF-20CM (Curb Mount Base) Solar Attic Fan  

Designed for curb mount installations. Generally a 2″x4″ or 2″x6″ curb box is built and flashing is attached to the perimeter of the curb box. Curb mount installations should be used on flat or very low slope roofs. Curb mount installations are also recommended for higher profile roofs, such as ceramic or concrete tile, certain metal roofs, thick wood shake, etc. The flashing materials are generally metal, but can be made of certain types of roofing materials. Care should be taken to isolate dissimilar metals and to properly waterproof the curb box to the roof. On top of the curb box, attach weather stripping or two sided foam tape. Place the SDF-20CM base on top of the curb box and fasten at least two screws on each side into the curb box.

It should be pointed out however that there are certain parameters that must be paid attention to for this installation to be affective.

Good sun exposure, preferably a  south-southwest afternoon exposure for optimum fan operation, but because the PV Panel orientation is vertical in this installation it is not 100% necessary. What is essential is proper elevation of the fan in relation to the ridgeline of the home (see diagram).  If the PV panel is allowed to fall into the shadow under the ridgeline it will stop generating power, at the precise time we’d like to see it operating at it’s strongest  AVAILABLE IN BLACK AND GREY
