DPT-M Silent Duct Fan

The DPT‑M Silent Duct Fan is one of those rare machines that you hardly notice — and that’s exactly the point. It delivers powerful, steady airflow with almost no noise, keeping air moving smoothly through long ducts or complex ventilation systems.

Built around a pure copper motor with precision ball bearings, it runs quietly, efficiently, and for years without complaint. The housing is slim and streamlined, making installation easy even in tight spots where every centimeter counts.

Despite its quiet operation, the DPT‑M pushes impressive air pressure capable of long‑distance air delivery — ideal for residential HVAC upgrades, office ceilings, or commercial setups that demand both strength and silence.

Energy use stays low thanks to its optimized motor design, so you get solid performance without needless power draw.

Reliable, compact, and whisper‑quiet, the DPT‑M Silent Duct Fan is one of those behind‑the‑scenes heroes that simply makes every space breathe easier.

Some fans move a lot of air — this one does it quietly.
The Acoustic Cabinet Fan was built for spaces where you need strong ventilation without the noise that usually comes with it. Each unit is made from thick galvanized steel and lined inside with 25 mm of fire‑proof sound‑insulating fiberglass (M0). The result is solid airflow with a calm, low hum instead of a constant roar.

Inside sits a forward‑curved centrifugal fan, directly driven by a single‑phase motor — simple, efficient, and reliable. The cabinet seals tightly with a removable cover, so it can work outdoors just as comfortably as indoors.

The motor is built like it means business: IP44 protection, Class B insulation, ball bearings, and built‑in thermal protection. It runs happily from ‑20 °C to +40 °C, drawing from a standard 230 V supply. There’s even a dual‑speed option for fine‑tuning performance to your system’s needs.

For projects that demand an even quieter touch, there’s a version with 50 mm fire‑rated acoustic fiberglass — the extra thickness adds another layer of calm to high‑pressure ventilation setups.

Installation is straightforward. It can be mounted any way you like — vertical, horizontal, or even upside down — thanks to its integrated feet and thoughtful design.

It’s one of those machines that doesn’t beg for attention. It just works — rugged, refined, and quiet enough to remind you that good engineering isn’t loud, it’s dependable.
