ATZAF FF (Double width double inlet airfoil housed fan)

ATZAF FF (Double width double inlet airfoil housed fan)

FEATURES:

• Steel impeller with 10 (x2) Airfoil blades, continuously welded. Wheel diameters range from 12” to 49”.
• Galvanized inlet cone with Forefinger (patented) and housing.
• Housing spot welded up to size 18’’, with Pittsburgh closure from size 20”
• Low maintenance ball or roller bearings
• Impeller with shaft statically and dynamically balanced at G 2.5
• Trapezoidal cut-off

BENEFITS:

• Suitable for applications up to 13.5” WG SP and volumes to 130,000 CFM
• Peak efficiencies over 80%
• Easy interchangeability with ATLI models thanks to standardized dimensioning.

FOREFINGER BENEFITS:

• Increased airflow and pressure: for a required volume and pressure the fan can run at lower rpm or can be selected smaller
• More uniform flow at the fan outlet for improved filter and coil efficiency
• Wider working range with high efficiency
• Significant reduction of noise, especially in the low frequencies
