Duty from the customer's GA drawing. Nothing rounded, nothing added.
A Maharashtra-based industrial-oven and furnace builder puts our fans inside the machines it ships. Oven-exhaust air movement is not a bolt-on for them — it is core to how their ovens work. When they design a build, the exhaust fan is part of the thermal answer, not an afterthought bought at the end.
Moving 57,200 CMH is one problem. Moving 57,200 CMH of hot oven-exhaust air, and holding both flow and 250 mmWC of static pressure while the fan sits in a heat stream, is a harder one. Heat changes air density, and density is what a fan trades in — so a fan that hits the numbers cold can fall short hot. The impeller and shaft have to keep their geometry and balance at temperature, run after run, without drifting off the curve.
Oven-exhaust and process centrifugal fans, engineered to this duty — made to order, not pulled off a shelf. Each fan is selected on our own fan-selection and mechanical-design software, then built to the geometry that duty demands.
Before it ships, every fan is performance-tested in-house on our 200 HP VFD test rig, to the IS 4894 / AMCA 210 method. We measure flow and pressure on the rig, not on a datasheet. That is the difference between proof and promises — you get a fan that has already run to its duty before it reaches your floor.
This is not a single order. It is a multi-year, repeat-supply line — build after build, oven after oven, the exhaust fans keep coming back to us. A fan you have to re-argue every time is a fan you do not trust; they stopped re-arguing ours a long time ago.
If you build ovens, furnaces, or any process that moves hot air, tell us the duty — airflow, static pressure, temperature, the medium — and we will tell you honestly whether we are the right fan for it. Our envelope runs to 2,00,000 CMH, 2,000 mmWC, 400 HP and 600 °C; your point sits somewhere inside it. Send us the GA drawing and let's work the numbers.

Engineered for Every Application.
No model numbers needed. Give us the operating conditions and our application engineers size the fan and quote it.
