Technical Data & Fan Selection
Catalogue selection ranges for the FRP TF/HF series and the metal TDC/TAA series, from the Winfan fan catalogues (FRP Fan Series, November 2023; Metal Fan Series, April 2023). All figures are approximate (≈), read from the catalogue performance charts. Selection data for guidance only — final selection confirmed by our engineers.

Series envelope: airflow ≈600–150,000 m³/h, static pressure ≈100–2,700 Pa. Power (kW) ratings include drive losses; performance ratings do not include system effects of fan accessories (catalogue note). Selection data for guidance only — final selection confirmed by our engineers.
Catalogue design features of the FRP series: backward-inclined impeller with logarithmic-profile, high-strength formed blades; oil-cooled bearing housing for long bearing life, easy maintenance and low mechanical noise; casing and steel-frame fasteners integrally pre-embedded during moulding, so corrosion cannot destroy the fixings; 24-hour, year-round service support.
HF Series — FRP High-Pressure Fans
| Sizes | Airflow (≈ m³/h) | Static pressure (≈ Pa) |
|---|---|---|
| HF-121B – HF-721B (11 sizes) | ≈50–100,000 | ≈400–5,900 |
For high-resistance corrosive-gas duty: wastewater deodorization, sludge drying, pharmaceutical chemicals, fibreglass production, rare-earth extraction, paper-mill anaerobic systems and acid recovery. Selection data for guidance only — final selection confirmed by our engineers.
TDC Series — Metal Centrifugal Fans (Coupling Drive)

|---|---|---|
| TDC-4.5 – TDC-18 (12 sizes) | ≈1,400–130,000 | ≈1,000–5,200 |

How to Read a Model Number
FRP Fans (TF / HF)
B TF-241 B
- Leading "B" — the complete fan set is explosion-proof. Without the B prefix, the fan is not whole-set explosion-proof (e.g. BTF-241B, BHF-301D).
- TF / HF — TF = medium & low-pressure fan; HF = high-pressure fan.
- Number — model / size (e.g. 241).
- Final letter — drive mode: B = belt drive; C = drive via coupling; D = direct drive by motor shaft.
Examples: TF-151B — medium/low-pressure fan, size 151, belt drive. HF-181C — high-pressure fan, size 181, coupling drive.
Metal Fans (TDC / TAA)
TDC-8 C
- TDC / TAA — metal centrifugal fan series; the TDC line is coupling-driven.
- Number — impeller diameter in decimetres: TDC-8 is the ≈800 mm impeller class, TAA-20 the ≈2,000 mm class.
- Final letter — drive mode: C = coupling drive, as used throughout the catalogue dimension tables (TDC-4C to TDC-18C; TAA-3.2C to TAA-20C).
Full per-size performance curves and dimension tables for all eight outlet directions are available in the catalogue — ask our engineers for the pages for your selected size.
A Note on the 12,000 Pa Figure
The maximum pressure of up to 12,000 Pa quoted on this page refers to Dingyu's custom ultra-high-pressure FRP fans — a separate, made-to-order line for ultra-high-resistance tail-gas systems. It is not part of the standard HF catalogue series above, whose selection envelope tops out at ≈5,900 Pa. If your system resistance is in that range, talk to our engineers about a custom selection.
