Guard Media Plastic filter Retainer Guard, retainer: UL94-V0 Media: UL900, 30 ppi (30 pores per inch) Mounting Method 1. Attach the guard to the Fan using the mounting bolts. (There are no mounting bolts provided with the Plastic Filter. ) 2. With the media held between the retainer and the guard, hook the retainer to the guard. (The media and retainer can be one-touch mounted/ dismounted. ) 3. Use the following model number to order media only.

[. . . ] Static pressure (Ps) is generated at the front of the fan when it rotates. P Fan Same as water level P P Fan Ps P+Ps Flow rate 3. Serial and Parallel Fan Operation The characteristics of two identical Fans operated in series or parallel are determined as shown in the following diagrams. Serial Operation: Maximum Flow Rate: Q max (m3/min. ) The volume of air discharged by the Fan when the static pressure is adjusted to zero (Pa) at the flow measurement unit. Maximum Static Pressure: Ps max (Pa) The pressure difference inside and outside the Unit when the flow rate is adjusted to zero (0 m3/min. ) at the flow measurement unit. Static pressure P 2 units System impedance 1 unit Pressure increase Fan P+ Ps max. Maximum value of difference Ps max. System Impedance: The flow resistance inside a mounted Axial-flow Fan caused by the density of parts and shape of the flow path. [. . . ]
