What this manufacturer offers
Jiangsu Yuhang HVAC Equipment Co., Ltd. describes itself as a manufacturer of ventilation and smoke-control equipment in Jingjiang. Its official address is No. 8 north of the old Sanyuan Bridge, Gushan Town, Jingjiang. The catalogue separates fans, dampers, fresh-air equipment, silencers, air outlets and heat exchangers. Its short company introduction supplies a production focus and corporate values, but not a dated plant inventory or output figure.
The fan catalogue is more useful for defining a project scope. It includes the HTFC cabinet centrifugal family, HTF axial family, induction fans, GXF and SWF mixed-flow families, and PYHL fire-related mixed-flow equipment. Individual families have different descriptions and thermal claims. A temperature-duration statement for HTF or PYHL is not a rating for the selected HTFC cabinet fan.
The separate damper publications identify actuation and signal functions. Those functions can inform a coordinated equipment schedule, while the precise fan duty, selected damper construction and project control logic still need their own documents.

03 / PROJECT REVIEW
Yuhang: coordinate fans and dampers without merging their ratings
Three fan families that require separate selections
The manufacturer's fan index distinguishes these constructions. It also lists induction, GXF and SWF equipment; the following comparison focuses on the three families with explicit ventilation/fire-related descriptions. (Source 3.)
HTFC: cabinet centrifugal
The page describes dual ventilation/smoke-extraction use and claims compact form, low noise and high-temperature resistance. It supplies no numerical airflow, pressure, sound or temperature-duration schedule. Select the full size/configuration before accepting those qualitative claims.
The index names HTF(GXZ/GYF), lists buildings and garages as intended applications, and prints its own 280°C/30-minute claim. An electric control box and silencer are described as optional, rather than confirmed HTFC accessories.
The catalogue describes a high-temperature motor and dedicated motor-cooling system, together with its own 300°C/60-minute statement. That construction and claim need a matching report if required for the order.
The HTFC parameter tab currently leaves the duty unresolved
Both the product description and detailed-parameter interaction were inspected. The latter displayed no numerical table or curve. The visible product image is a cabinet centrifugal arrangement; it does not establish the exact motor position, motor rating, speed configuration or outlet arrangement supplied for a project. (Source 2.)
A selected HTFC offer should therefore identify the airflow and required pressure with the pressure definition, the operating speed and electrical data, and the actual installation drawing. The source's low-noise claim also needs a numerical acoustic basis and measurement condition if noise is a design constraint. No size or duty has been manufactured from the generic family title.
Where normal ventilation and smoke extraction are both intended, request the actual selected control and operating arrangement. The phrase “one machine, two uses” alone does not prove a two-speed motor or a specified changeover circuit. The order needs the motor/speed configuration and mode sequence explicitly.
Fire-damper closure and smoke-damper opening are different functions
The fire-damper publication describes a normally open valve closing under spring force when the fusible element acts at 70°C. It also describes a closed-position output and manual close/reset-open operation. These statements concern the damper, not the fan's temperature resistance. (Source 4.)
The same site's smoke-valve descriptions refer to DC24V electrical opening, manual opening, an open signal for fan interlocking, and manual reset to close. Before pairing equipment, identify which valve function belongs to each location and obtain a selected wiring diagram. A catalogue interlock sentence does not establish the complete project's safety logic.
Fire damper: close and report closure
The reviewed source's sequence is normally open → 70°C fusible action → spring closure → closed-position signal. Confirm the exact actuator/fusible assembly and contacts on the proposed model.
Smoke control: identify opening and interlock signals
The neighbouring catalogue descriptions refer to electrical/manual opening and fan-interlock output. They are separate product functions; do not substitute the normally open fire-damper sequence without the selected model's documentation.
What the site does and does not establish about fire duty
Yuhang's catalogue says PYHL-14A underwent a high-temperature test at a named national fire-equipment testing centre. The reviewed material does not reproduce a report number, date or tested size/configuration, so that remains a supplier statement. It is not an approval covering the entire catalogue. The HTF temperature-duration statement is likewise not a substitute for the order's matched evidence. (Source 3.)
The official honours page was also opened and rendered, but displayed headings rather than readable certificate records. This is a document gap, not a conclusion that the company has no certification. Obtain issuer, number, coverage and current status for the proposed fire-related equipment. (Source 5.)
An external search located a 2022 technology-based small-enterprise list candidate containing the company name. Its original government PDFs could not be retrieved for full verification during this review. It is excluded from verified facts, and even a confirmed historical enterprise listing would not certify an HTFC fan's fire performance.
Use the manufacturer scope to build a coordinated equipment list
Yuhang's published range can support an enquiry covering the fan, duct damper, acoustic treatment and air-distribution components. Assign an exact product/configuration and document requirement to each line. A fan catalogue range should not stand in for damper contacts, and a damper actuation value should not stand in for the fan's electrical selection. (Sources 1–4.)
For the cabinet fan specifically, include the available plant-room/ceiling space, connection directions and maintenance access when requesting a drawing. Resolve the normal/fire operating arrangement and motor access using that drawing. These are project selection requirements; they are not undocumented Yuhang construction features.
The current profile establishes the manufacturer's published ventilation/smoke-control focus and the distinctions among named families. It leaves production output, selected duty and model-specific approvals open until the relevant current documents are supplied.
