No attic or other interior space for an inline fan? Go with our ASKR systems that use an exterior roof-mount fan. Similar performance and every bit as quiet. Smoke, heat, grease and odors are efficiently whisked away while you and your family and friends enjoy a peaceful, fresh-smelling kitchen.
Kit components:
Powerful S&P Exterior Fan:
These heavy-duty commercial fans are built into a weather-proof shroud so they can be placed on either flat or sloped roofs. Manufactured by S&P, the world’s biggest air movement company, these same fans are sold to restaurants and commercial builders around the world. Proven reliable in heavy-duty applications, they’ll do great in your kitchen. Specs vary by fan size; see individual PDF spec sheets below.
Duct Silencer:
Locating the fan away from the range hood makes a huge difference but we don’t stop there. This special purpose silencer acts like a car muffler, eliminating any fan noise that may be radiating down the ducting.
Backdraft Damper;
A spring-loaded backdraft damper mounts in-line just before the roofcap, automatically closing when the system is not in use to prevent outside air from funneling into the house.
These outdoor units are only available in larger sizes:
model; airflow; duct size; fits liners; for cooktops;
ASKR-42, 510 CFM, 10 inch, AHL-42, 36-42 inch
ASKR-48, 645 CFM, 12 inch, AHL-48, 42-48 inch
What is NOT included in these kits?
* Rigid duct is a commodity item that just doesn’t make sense for us to ship. It’s available in nearly any home improvement store; pick up the quantity that your installation requires. Note: Do NOT use flexible duct for kitchen installations.
* Duct tape is required to seal all the joints. You can use the generic stuff, or, order a roll or two of our favorite premium duct tape.
