Specification Checklist
• Units provide general supply (SASD) or exhaust (SAED) of low,
medium or high air volumes in commercial, institutional and light
manufacturing buildings.
• Weatherproof heavy duty aluminum housing resists corrosion
and maintains appearance.
• Deep-spun, one-piece venturi improves efficiency and
minimizes pressure losses.
• Bird screen prevents entry of birds or other potentially damaging

Installation :- All models are shipped fully assembled and ready for installation. Always inspect equipment for transit damage before accepting delivery to assure a valid claim. 

Placement :- Refer to local building codes for placement of exhaust air streams relative to supply air streams.

Mounting:- Satisfactory operation of roof ventilators requires mounting on adequately designed and constructed roof curbs. Prefabricated curbs for convenience in installation are available from ILG. Install with base of unit horizontal. Provide adequate caulking, flashing or other weatherproofing means. 

Options & Accessories

Prefabricated Roof Curbs:- Insulated roof curbs with weather-resistant continuous welded construction are available for convenience in installation for both insulated and non-insulated roof decks.

Backdraft Dampers:- Gravity or motor operated backdraft dampers are available. They are aluminum construction and designed for installation in prefabricated roof curbs.

Protective Coatings:- Ventilator units are not recommended for exhausting air of a corrosive nature. However, special protective coatings are available where units may be exposed to corrosive exterior conditions. Parts requiring painting are processed through the American Coolair multistage pretreatment system prior to the application of any coatings to insure maximum finish adhesion. These parts use a thermosetting epoxy powder paint with an average thickness of 3 mils and baked at 400° F to a smooth, hard continuous finish. Consult your ILG Industries representative for available coatings.
