Greenheck-fan Steel Airfoil Blades SMD-301M Manuel d'utilisateur télécharger pdf

Model SMD-301M meets the requirements for

smoke dampers established by:

National Fire Protection Association

NFPA Standards 92A, 92B, 101 & 105

IBC International Building Codes

New York City (MEA listing #260-91-M)

CSFM California State Fire Marshal

Leakage (Smoke) Damper Listing (#3230-0981:104)

APPLICATION

Model SMD-301M is a leakage rated modulating smoke damper

with class I leakage. The SMD-301M serves the function of both

a control damper and smoke damper. High strength airfoil blades

insure lowest resistance to airflow in HVAC systems with velocities

to 2000 fpm (10.2m/s) and 4 in. wg (1 kPa) Model

SMD-301M may be installed vertically (with blades running hori-

zontal) or horizontally and is rated for airflow and leakage in either

direction.

UL 555S Leakage Rating

Leakage Class: I

Operational Rating

Maximum Pressure: 4 in. wg (1 kPa)

Maximum Temperature: 250ºF (121ºC)

STANDARD CONSTRUCTION

Frame: 5 in. x 1 in. (127mm x 25mm)

galvanized steel hat channel with

reinforced corners. A low profile

head and sill are used on sizes less

than 17 in. (432mm) high to

maximize free area and

performance.

Blades: Double skin airfoil shape of

galvanized steel with full length

structural reinforcement. 14 ga.

(2 mm) equivalent thickness.

Seals: Extruded silicone rubber blade

seals. Flexible stainless steel jamb

seals.

Linkage: Concealed in jamb.

Axles:

/2 in. (13mm) dia. plated steel.

Bearings: Bronze sleeve type.

SIZE LIMITATIONS:

Minimum Size:

8 in. W x 6 in. H

(203mm W x 152mm H)

Maximum Size:

Single Section - 32 in. W x 50 in. H

(813mm W x 1270mm H)

Multiple Section - 128 in. W x 100 in.

(3251mm W x 2540mm H)

OPTIONAL FEATURES:

• Galvanized steel sleeves.

• Stainless steel bearings

• OCI (Open closed indication switches)

• Electric actuators to accomplish smoke management and system

functions.

• Transitions (R, C, O)

• POC retaining angles

• Momentary Switch
