S&P TTT-N Series Cylindrical Cased Axial Flow Fans

Product Overview

The S&P TTT-N Series offers robust cylindrical cased axial flow fans designed for continuous operation in demanding environments, including high temperatures up to 120°C. These fans feature a motor located externally to the fan casing, connected via a belt-driven impeller system.

The fan casings are constructed from high-grade rolled sheet steel, protected by a cataforesis primer and a durable black polyester paint finish. The drive system utilizes an industrial poly V-belt pulley system, safely enclosed within a metal protective guard. All models are equipped with diecast aluminium impellers, available with either 2 or 3 fixed blade angles, and finished in black polyester paint coating.
