Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is essential for the following industrial systems and equipment:
| pressure: | Up to 25 psi differential pressure (standard), higher with reinforced designs |
| flow rate: | Dependent on damper size and blade configuration - typically rated for velocities up to 5000 fpm |
| temperature: | -40°C to 400°C (depending on material and seal selection) |
| slurry concentration: | Not recommended for abrasive slurries >5% solids by weight without special coatings |
Indicative industry ranges for design and RFQ preparation. Confirm the exact figures and applicable standard with the manufacturer before specifying.

CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
Damper frames are available in galvanized steel, stainless steel, and aluminum. Material grades include Q235B, 304, and 316L, referencing standards such as GB/T 700 and ASTM A240. The choice depends on the application environment, with stainless steel recommended for corrosive conditions.
Standard frame widths and heights range from 200 to 2000 mm, with depths from 150 to 500 mm. Custom sizes are available. Frame thickness typically ranges from 1.5 to 3.0 mm, and weight varies from 15 to 150 kg depending on size and material.
Damper frames are designed for operating temperatures from -40 to 85°C. Leakage rates range from 0.1% to 1.0%. Surface treatment includes epoxy coating of 60–120 μm thickness per ISO 12944 for corrosion protection.
Frame flatness tolerance is ±0.5 mm/m. This ensures proper blade seal alignment, which is critical for maintaining low leakage rates and reliable operation. Excessive flatness deviation can lead to seal gaps and reduced performance.
