4. Air filter and silencer

At blower inlet: Series F64, provide 16 dB ~ 20 dB noise reduction and 98% removal efficiency

on 10 micron particles.

Select 4 F64-8, Air rating < 1,800 CFM

Pressure drop = 2.5 in H₂O = 0.09 Psi

At blower outlet: BMSI silencer

5. Total head loss in piping system

D H = 0.09 + 0.1 + 0.05 = 0.24 Psi
