Fresh Filtered Air Unit Roof Supply Fan – 10 in

Specifications

Features

• Fully welded, full-mold construction distributes rooftop vibration loads evenly across the casing without localised stress at fastener joints
• Galvanized sheet or stainless steel housing choice matched to the grease exposure level at each specific installation point above the served space
• Axial impeller profile delivers 2,100 CFM with a noise footprint low enough for rooftop units positioned directly above occupied dining or retail areas
• Compact rooftop envelope seats onto a standard duct curb without requiring an enlarged roof penetration or additional structural framing
• Direct inline connection to a standard 10-inch circular duct removes the static pressure penalty that a transition fitting would introduce at the fan inlet
• Certified under China’s Energy Saving Label program, verifying motor and impeller efficiency at the 1 HP / 2,100 CFM rated operating point
• ISO 9001:2000 quality management standard governs impeller balance tolerances, housing weld inspection, and final airflow verification for every unit prior to shipment

The 10-inch Fresh Filtered Air Unit delivers 2,100 CFM at 1 HP, sized for small restaurant kitchens, cafes, and light commercial spaces where a single 10-inch circular duct penetration covers the building’s entire fresh air allocation. Its axial impeller geometry keeps mechanical noise low enough for installations directly above occupied dining or retail zones where intrusive sound from the air supply system would affect the customer environment.

At 2,100 CFM, this unit replaces the air in a 1,000 sq ft restaurant dining area approximately every four to five minutes when paired with an equivalent exhaust system — meeting the 12 to 15 air changes per hour standard for food service occupancies without requiring a motor larger than the 1 HP class. The housing material choice is most consequential for this model size: units above light sandwich or pastry preparation accumulate far less airborne grease than those above wok stations, making galvanized steel sufficient for the former and stainless steel the correct selection for the latter.

This 10-inch / 2,100 CFM unit is the entry point of the Fresh Filtered Air Unit series. When the required supply volume exceeds 2,500 CFM or the available duct penetration diameter allows a larger connection, the Fresh Filtered Air Unit Roof Supply Fan – 12 in at 3,600 CFM and 1.5 HP is the correct next step up in this line.
