Greenheck WD-400 Series Bedienungsanleitung

Application and Design

The WD-400 series are non-motorized backdraft dampers which may be mounted either vertically for intake air or mounted

horizontally to allow vertical airflow down and prevent reverse airflow. The dampers are opened by air pressure differential and

closed by springs. Optional motor packs are not available.

Pressure Drop

36 in. x 36 in. (914mm x 914mm) Damper

Performance data results from testing a 36 in. x 36 in. (914mm x 914mm) damper in accordance with AMCA Standard 500-D

using Figure 5.3 for the WD-400 and Figure 5.7A for the WD-410. All data has been corrected to represent standard air at 0.075

lb/ft3 (1.201 kg/m3).

Leakage

36 in. x 36 in. (914mm x 914mm) Damper

Leakage testing was conducted in accordance with AMCA

Standard 500-D and is expressed as cfm/ft2 of damper face

area. All data has been corrected to represent standard air at

0.075 lb/ft3 (1.201 kg/m3).

Note: A 26 in. x 26 in. and a 30 in. x 30 in. WD-410 will be supplied as a Double Panel, One Section damper.

• Multiple section dampers shown below are supplied as equal size sections. Any damper that has multiple sections, both

vertically and horizontally, will require field assembly and will require additional reinforcement (not supplied by Greenheck)

to support the assembly. These larger dampers must have the additional reinforcement to give them structural stability.

• Please note that the width dimension is always taken as being parallel to the length of the blades.
