Question

Should you mount the Finger Guard and Filter on either the label side of the Axial-flow Fan or on the opposite side depending on whether the inlet side or the outlet side is mounted facing forward?

Answer




Exhausting Air from the Outlet

As shown in the following diagram, a Finger Guard must be mounted on the front (label) side of the Axial-flow Fan to prevent an operator from being injured from outside the panel. When installing the Fan on a panel door, another Finger Guard must also be mounted on the rear side of the Fan when there is a possibility that an operator's finger might touch a fan blade from the rear of the Fan when the panel door is being opened or closed.

Taking Air in Through the Inlet

As shown below, a Finger Guard must be mounted on the rear side of the Axial-flow Fan to prevent an operator from being injured from outside the panel. Similar to the case when exhausting air from the outlet, when installing the Fan on a panel door, another Finger Guard must also be mounted on the front (label) side of the Fan when there is a possibility that an operator's finger might touch a fan blade from the front of the Fan when the panel door is being opened or closed.
