AIR DATA
1Choose operating point.Begin at 3,500 cfm.
2Find Bhp. Draw parallel HP line through the intersection found in Step 1.
3Find Total Efficiency (TE). Use 3,000 TE curve to find your operating TE.
1Find cfm at 100% WOV (6,500 cfm) from the fan curve (3,000 rpm) at selected operating point (3,500 cfm) at 5.1 in wg.
2Calculate your % WOV at operating point using equation:% WOV = (3500 ÷ 6500) x 100 = 53.8
3Find LwA value. Use the % WOV value calculated in Step 2. Locate the LwA (3,000) curve and draw a line to the right to find your LwA value of 91.5
Greenheck India Pvt Ltd. certifies that the CDB models shown herein are licensed to bear the AMCA FEI Seal. FEIT values are calculated in accordance with ANSI/AMCA Standard 208 and are based on default motor efficiencies (50 Hz IE2). FEIT values for fans with specific motors will vary slightly from those shown.

Performance certified is for installation type B: free inlet, ducted outlet. Performance ratings do not include the effects of appurtenances (accessories). Power rating (HP) does not include transmission losses. The A-weighted sound power ratings shown have been calculated per AMCA Standard 301. Values shown are for Inlet LwA sound power levels for: Installation Type B: free inlet, ducted outlet. Ratings do not include the effects of duct end correction for the outlet duct. FEI T values are calculated in accordance with ANSI/AMCA Standard 208 and are based on default motor efficiencies (50 Hz IE2). FEI T values for fans with specific motors will vary slightly from those shown.

Performance certified is for installation type B: free inlet, ducted outlet. Performance ratings do not include the effects of appurtenances (accessories). Power rating (HP) does not include transmission losses. The A-weighted sound power ratings shown have been calculated per AMCA Standard 301. Values shown are for Inlet LwA sound power levels for: Installation Type B: free inlet, ducted outlet. Ratings do not include the effects of duct end correction for the outlet duct. FEI T values are calculated in accordance with ANSI/AMCA Standard 208 and are based on default motor efficiencies (50 Hz IE2). FEI T values for fans with specific motors will vary slightly from those shown.

Performance certified is for installation type B: free inlet, ducted outlet. Performance ratings do not include the effects of appurtenances (accessories). Power rating (HP) does not include transmission losses. The A-weighted sound power ratings shown have been calculated per AMCA Standard 301. Values shown are for Inlet LwA sound power levels for: Installation Type B: free inlet, ducted outlet. Ratings do not include the effects of duct end correction for the outlet duct. FEI T values are calculated in accordance with ANSI/AMCA Standard 208 and are based on default motor efficiencies (50 Hz IE2). FEI T values for fans with specific motors will vary slightly from those shown.

Performance certified is for installation type B: free inlet, ducted outlet. Performance ratings do not include the effects of appurtenances (accessories). Power rating (HP) does not include transmission losses. The A-weighted sound power ratings shown have been calculated per AMCA Standard 301. Values shown are for Inlet LwA sound power levels for: Installation Type B: free inlet, ducted outlet. Ratings do not include the effects of duct end correction for the outlet duct. FEI T values are calculated in accordance with ANSI/AMCA Standard 208 and are based on default motor efficiencies (50 Hz IE2). FEI T values for fans with specific motors will vary slightly from those shown.
