SP – Standard Profile https://l.ead.me/beFxTD

1. Extruded aluminum (6063-T5) damper frame is not less than 0.080” (2.03 mm) in thickness. Damper frame is 4” (101.6 mm) deep x 1″ (25.4 mm), with mounting flanges on both sides of frame. Damper frame has a 2″ (50.8 mm) mounting flange on the rear of the damper, when ordered as Extended Rear Flange install type.
2. Blades are maximum 6” (152.4 mm) deep extruded aluminum (6063-T5) air-foil profiles. All blades are symmetrically pivoted.
3. Blade seals are extruded EPDM. Frame seals are extruded silicone. Seals are secured in an integral slot within the aluminum extrusions. Blade and frame seals are mechanically fastened to prevent shrinkage and movement over the life of the damper.
4. Bearings are composed of a Celcon inner bearing – fixed around a 7/16” (11.11 mm) aluminum hexagon blade pivot pin – rotating within a polycarbonate outer bearing inserted in the frame. This eliminates action between metal-to-metal or metal-to-plastic riding surfaces.
5. Adjustable 7/16” (11.11 mm) hexagonal drive rod, U-bolt fastener, and hexagonal retaining nuts are zinc-plated steel. These provide a positive connection to blades and linkage.
6. Aluminum and corrosion-resistant zinc-plated steel linkage hardware is installed in the frame side, complete with cup-point trunnion screws for a slip-proof grip.
7. Dampers are designed for operation in temperatures ranging from -40°F (-40°C) to 212°F (100°C).
8. Leakage Class 1A at 1 in. w.g. (0.25 kPa) static pressure differential. Standard air leakage data is certified under the AMCA Certified Ratings Program.
9. Dampers are custom made to required size, without blanking off free area. The blade stop is set at a fixed height and is a continuous and integral part of the top and bottom frames.
10. Dampers are available with either opposed blade action or parallel blade action.
11. Dampers are available in four install types: Installed In Duct, Flanged to Duct, Extended Rear Flange, and Square to Round Transition. (See Install Types pages for details.)
12. Installation of dampers must be in accordance with TAMCO’s current on-line installation guidelines. (Printed installation guidelines are provided with each damper shipment, however all technical information available on TAMCO’s web site at www.tamcodampers.com supersedes information contained within printed versions.)
13. Intermediate structural support is required to resist applied pressure loads for dampers that consist of two or more sections in both height and width. (See TAMCO Aluminum Damper Installation Guidelines.)

PERFORMANCE DATA

VELOCITY VS. PRESSURE DROP T.A. Morrison & Co. Inc. certifies that the TAMCO Series 1000 Air-Foil Control Damper with SP – Standard Profile shown herein is licensed to bear the AMCA Seal. The ratings shown are based on tests and procedures performed in accordance with AMCA Publication 511 and comply with the requirements of the AMCA Certified Ratings Program. The AMCA Certified Ratings Seal applies to air leakage and air performance ratings. https://l.ead.me/beFxTD

FIG. 5.3 Test damper is fully ducted with a 5 diameter duct run upstream, and a 6 diameter duct run downstream.
Pressure drop values are based on Flanged to Duct install type.
Pressure drop will be greater for In Duct install type dampers.

BLADE DESIGN PRESSURE LIMITATIONS Series 1000 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).

FIG. 5.4 Test damper is located at the entrance of a plenum.
FIG. 5.5 Test damper is located at the exit of a plenum.
Air Performance testing was conducted in accordance with ANSI/AMCA Standard 500-D.
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. The pressure drop for WP TAMCO dampers is less than the pressure drop of the opening alone.
BLADE DESIGN PRESSURE LIMITATIONS

Series 1000 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 multiplesection 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).
