TAMCO LEAKAGE RATING

BLADE DESIGN PRESSURE LIMITATIONS

Series 9000 dampers with SP – Standard Profile, whose blade length exceeds the maximum design pressure, may be reconfigured to maintain a blade length compatible with the required system pressure by increasing the number of sections per damper and thereby reducing each damper section’s blade length. Appropriate intermediate structural support will be required for all multiple- section damper assemblies. (Refer to line 13 of the Submittal Data and to TAMCO’s Aluminum Damper Installation Guidelines.)

Example:
A single-section damper of 60”w x 36”h (1524 mm x 915 mm) at 5 in w.g. (1.24 kPa) would need to be built in two sections of 30”w x 36”h (762 mm x 915 mm).

Leakage testing was conducted by ANSI/AMCA Standard 500-D, Figure 5.4. Data are based on a torque of 10.8 in-lb/ft² (13.1 N-m/m²) and a minimum of 70 in- lb (7.9 N-m) applied to close and seat the opposed blade damper during the test. Air leakage is based on operation between 32 °F (0 °C) and 120 °F (49 °C).

The following sizes of TAMCO Series 9000 dampers with no Option or MR Option, and SP – Standard Profile were tested: 12″ x 48″ (305 mm x 1220 mm), 36″ x 36″ (915 mm x 915 mm), 48” x 36” (1220 mm x 915mm), 60″ x 36″ (1524 mm x 915 mm).

• FIG. 5.4 The test damper is located at the entrance of a plenum.
• FIG. 5.5 The test damper is located at the exit of a plenum.
• Air Performance testing was conducted by ANSI/AMCA Standard 500-D.
• Pressure drop values are based on the Flanged to Duct install type. The pressure drop will be greater for In-Duct install-type dampers.

BLADE DESIGN PRESSURE LIMITATIONS

The table above shows AMCA Figure 5.4 (intake) and Figure 5.5 (exhaust) pressure drop test results for a range of opening sizes. Pressure drop tests were conducted for each of the following:

• System Only. (No damper installed in the opening.)
• Damper & System. (TAMCO damper installed in the opening.)

The third column (Damper Only) under each AMCA Figure shows what effect the TAMCO WP dampers have on the airflow through each opening size. This is calculated by subtracting the Damper and System results from the System Only results.

Series 9000 dampers with WP–Wide Profile, whose blade length exceeds the maximum design pressure, may be reconfigured to maintain a blade length compatible with the required system pressure by increasing the number of sections per damper and thereby reducing each damper section’s blade length. Appropriate intermediate structural support will be required for all multiple- section damper assemblies. (Refer to line 13 of the Submittal Data and TAMCO’s Aluminum Damper Installation Guidelines.)

Example:
A single-section damper of 60”w x 36”h (1524 mm x 915 mm) at 5 in. w.g. (1.24 kPa) would need to be built in two sections of 30”w x 36”h (762 mm x 915 mm).

INSTALL TYPES

Thermally Insulated Damper with Thermally Broken Blades

• Always provide opening width and height dimensions, when ordering.
• The width dimension is always parallel to the blades.
• The height dimension is always perpendicular to the blades.

INSTALLED IN DUCT TYPE

• Applies to SP and NP Profiles only. Not available for WP Profile.
• The finished damper O.D. is ½” (12.7 mm) less than the opening width and height dimensions.

MINIMUM SECTION SIZE:

SP| 6½”w x 6¾”h| (166 mm x 172 mm)
NP| 6½”w x 12⁵/8”h| (166 mm x 320 mm)
MAXIMUM SECTION SIZE:
 | 25 ft²| (2.3 m²)
 | 60”w x 60”h or| (1524 mm x 1524 mm) or
 | 48”w x 75”h| (1220 mm x 1905 mm)

FLANGED TO DUCT TYPE

• For SP and NP Profiles, the finished damper O.D. is 2” (50.8 mm) greater than the opening width and height dimensions.
• For the WP Profile, the finished damper O.D. is 3.25” (82.6 mm) greater than the opening width and height dimensions.

MINIMUM SECTION SIZE:

SP/WP| 4½”w x 4¼”h| (115 mm x 108 mm)
NP| 4½”w x 10⅛”h| (115 mm x 257 mm)
MAXIMUM SECTION SIZE:
 | 25 ft²| (2.3 m²)
 | 60”w x 60”h or| (1524 mm x 1524 mm) or
 | 48”w x 75”h| (1220 mm x 1905 mm)

EXTENDED REAR FLANGE TYPE

• Applies to SP and NP Profiles only. Not available for WP Profile.

• The finished damper O.D. is 4” (101.6 mm) greater than the opening width and height dimensions.
  MINIMUM SECTION SIZE:

  SP| 4½”w x 4¼”h| (115 mm x 108 mm)
  NP| 4½”w x 10⅛”h| (115 mm x 257 mm)
  MAXIMUM SECTION SIZE:
   | 25 ft²| (2.3 m²)
   | 60”w x 60”h or| (1524 mm x 1524 mm) or
   | 48”w x 75”h| (1220 mm x 1905 mm)

• Extended Rear Flange install type dampers are not designed so that the front of the damper may be inserted into an opening, as the side frame members extend to the full height of the rear flange.

SQUARE-TO-ROUND TRANSITION

• Applies to SP and NP Profiles only. Not available for WP Profile.
• Always provide duct diameter dimensions when ordering.
• If using TAMCO Connect software to submit orders, enter duct diameter dimensions in both the width and height fields.
• Transition pieces are a minimum of 18 ga. galvanized steel for Series 9000 dampers, when ordered no option or with the SC Option.
• Transition pieces are 304 stainless steel when Series 9000 dampers are ordered with MR or SW Options.
• Transition pieces and damper are sealed together.
• Dampers are built 4” (102 mm) larger than the specified duct diameter. (Dampers are fabricated square.)
• The finished transition diameter is ¼” (6.35 mm) less than the specified duct diameter, providing clearance for the mating duct which slides over a round transition. This ensures free movement of damper blades.

MINIMUM DUCT DIAMETER:

SP| 4”| (102 mm)
NP| 8⅛”| (206 mm)
MAXIMUM DUCT DIAMETER:
 | 58”| (1474 mm)
MAXIMUM SECTION SIZE:
 | 25 ft²| (2.3 m²)
MAXIMUM FINISHED OD:
 | 62”w x 62”h| (1575 mm x 1575 mm)

NOTE:

• To reduce pressure drop, use Flanged to Duct or Extended Rear Flange install types for sizes under 9 ft² (.83 m²).
• Suitable for operation in breathable air environments within the stated temperature range.
• SP and WP dampers sized for duct openings exceeding 373/4” (959 mm) in height and NP dampers sized for duct openings exceeding 35¾” (908 mm) are equipped with a brace at mid-height to strengthen and maintain air leakage tolerances.
• Thermally insulated dampers should not be installed or stored in locations where insulation is in direct line of sight of sunlight or UV light.
