Fantech has added two new models to its TD Silent series of low noise exhaust fans.
Fantech Engineering manager Kerry Dumicich claims the TD Silent 250mm and TD Silent 315mm models were high performance, high capacity fans that were quieter than any other fan in their class.
“This breakthrough in noise reduction is due to a technically advanced design and internal construction,” he said.
“Sound waves produced inside the fan are captured by a sound-absorbent internal membrane resulting in an efficient low profile fan that operates very quietly.”
Dumicich said the TD Silent series was a real advance in acoustic technology. At three metres the TD Silent 250mm has a sound pressure of 42dBA in low speed and 47dBA in high speed. The 315mm has a sound pressure of 44dBA in low speed and 50dBA in high speed.
“The smaller fans produce even less noise, making the TD Silent series perfect for hospitals, apartments, hotels and offices where the constant sound of the ventilation system could distract the occupants,” he said.
Engineers of the TD Silent had looked at all sources of noise and provided adaptations in these two new models, such as its aerodynamic inlet to improve air flow performance and further reduce noise.
“They have created a series that is compact and ideal for installations in false ceilings where space is often restricted,” Dumicich said. “The larger fan body of the TD Silent 250 and TD Silent 315 can be easily separated from the ducting for cleaning and maintenance by removing four screws at each end of the fan.”
The 150mm and 200mm models have a sleek body manufactured from reinforced injection moulded polypropylene plastic. The larger 250mm and 315mm models are constructed from durable sheet steel finished in a protective epoxy polyester paint to provide strength and help minimise the fan’s dimensions. The larger models also feature an external terminal box which is rated at IP55.
The TD Silent series of fans is now available in 150, 200, 250 and 315mm spigot diameter models.
