Pengenalan Produk

This taller-than-wide assembly uses an airfoil blade bank within a rigid steel frame. Its three-hour configuration and higher pressure selection distinguish it from the standard 1.5-hour square models.

Ciri-ciri Utama

Airfoil blades provide a defined passage through the open damper.
Vertical configuration fits taller shaft and partition openings.

Applications

High-rated vertical shaft penetrations
Combined compartment barriers on substantial duct routes

Solutions for Your Application

The barrier calls for a higher fire-resistance configuration.

This selection identifies a three-hour assembly rather than extending the rating of the lighter-duty model.

The duct system imposes elevated pressure on closed blades.

The model uses the higher-pressure configuration appropriate to its blade and frame arrangement.
