Twin City Fan: Products, competitors, and EPD coverage
Twin City Fan is a pure play in air movement, with a deep catalog of fans and blowers for buildings and industry. The portfolio is broad, the paperwork less so. If projects ask for product‑specific EPDs, how ready are they to compete today?
Who they are
Twin City Fan and Blower designs and manufactures air‑movement equipment for commercial buildings and heavy industry. Their portfolio spans ventilation, process, and specialty applications across sectors like healthcare, data centers, education, food, wastewater, and energy. The company sells under the TCF brand and focuses on performance, reliability, and application engineering.
What they sell, at a glance
Twin City Fan is not a mixed materials conglomerate. They are focused on fans and related assemblies. Typical product families include:
- Centrifugal, inline centrifugal, mixed‑flow, and plenum fans
- Vaneaxial and tubeaxial fans, propeller and roof exhausters
- Laboratory and fume exhaust, smoke control, high‑temperature units
- Fiberglass reinforced plastic fans, pressure blowers, OEM specials
Across sizes, drive types, impellers, housings, and accessories, the SKU count easily lands in the hundreds, with more than a dozen distinct product categories. If you spec air movement often, you have seen these shapes before.
Current EPD coverage
As of December 25, 2025, we could not find any publicly listed, third‑party verified product‑specific EPDs for Twin City Fan’s catalog. If an internal or private declaration exists, it is not visible in common public registries. That creates friction on bids where owners or designers prefer verifiable declarations rather than marketing PDFs.
Why it matters on specs
LEED v5 draft language and many corporate procurement policies reward product‑specific EPDs, often with clear preferences in scoring. Without one, teams must use conservative default factors in carbon accounting, which can make otherwise solid products look heavier on paper. The result is fewer at‑bats on projects that track embodied carbon.
The competitive field, briefly
Several HVAC peers are publishing EPDs in adjacent product areas. Systemair lists EPDs for residential AHUs and a jet fan with validity into 2029, published through EPD Norway (EPD Norway, 2029) (EPD Norway, 2029). Swegon publishes a broad set of AHU EPDs in North America via EPD Hub, many with validity dates in 2030 (EPD Hub, 2030) (EPD Hub, 2030). Greenheck has multiple louvers with current EPDs through Smart EPD valid into 2030, which signals a ventilation‑ecosystem push specifiers notice (Smart EPD, 2030) (Smart EPD, 2030). TROX also publishes component EPDs through EPD Norway with current validity windows.
A likely best‑seller at risk
Inline and plenum fans are frequent picks for offices and data halls. When an AHU vendor walks in with a unit‑level EPD that already covers its integrated fans, the simple answer often wins the drawing. That does not mean a standalone fan cannot compete, it means the paperwork must keep pace.
Not just government work
Federal Buy Clean momentum has cooled in 2025, so do not count on it to pull demand. Private owners, higher‑ed, healthcare networks, and tech campuses still write EPD preferences into specs, and LEED‑seeking projects are not slowing down. The market signal remains strong where it counts, on actual bids.
How Twin City Fan could close the gap fast
Start with one high‑volume family, for example an inline centrifugal line with EC motors. Pick the most relevant PCR based on competitor practice in your target applications, then choose a program operator that your customers recognize. If a full year of production data is not ready, a prospective EPD can launch on a shorter data window, then be updated after twelve months of operations. A great LCA partner will make data collection painless across plants, ERP, utilities, and suppliers, and will publish cleanly with Smart EPD in the US or IBU in Europe. The lift feels heavy at first, then it becomes repeatable.
What to watch on their site
We did not find a dedicated sustainability or EPD resource hub on Twin City Fan’s website. If a page exists, surfacing it clearly with model‑by‑model coverage would help design teams move faster. That small content change punches above its weight in pre‑bid Q&A.
The commercial payoff
EPDs reduce spreadsheet penalties and keep products in contention when carbon targets are tight. One well‑timed declaration for a core fan family can unlock entire project pipelines, because it removes a reason to swap you out late. The enviromental story is real, the sales story is closer.
Frequently Asked Questions
What kinds of Twin City Fan products are most likely to benefit first from an EPD?
High‑volume inline, plenum, and roof exhaust families used in offices, education, and healthcare. These see repeated specifications, so one product‑specific EPD can influence many bids.
Do competitors in fans already publish EPDs?
Several ventilation peers publish EPDs in adjacent gear like AHUs, components, and louvers. Examples include Systemair and TROX via EPD Norway, Swegon via EPD Hub, and Greenheck via Smart EPD.
If we lack a full year of plant data, can we still publish?
Yes. A prospective EPD can start on a shorter window, then be revised once 12 months of production data are available. That keeps sales moving while the dataset matures.
Which program operators are familiar to North American specifiers?
Smart EPD is increasingly visible in the US, and IBU and EPD International are common in Europe. EPD Hub is also active in North America, particularly for HVAC equipment.
Will older EPDs hurt our chances if they are still valid?
No. Within the validity window, age rarely matters to buyers. What matters is having a current, third‑party verified declaration that removes default penalties in carbon accounting.
