Fläkt Wood's PFT axial fan combines compact size for minimum space requirements with high pressure, and high efficiency, throughout its entire operating range.
PFT is a two stage axial flow fan which develops double the pressure rise compared to that of a conventional single stage fan. The fan has two impellers mounted on a common shaft with a guide vane arrangement between the two impellers. The fans operating point is quickly adjusted to the system load demand by varying the pitch of the hydraulically adjustable impeller blades.
The PFT axial is high-pressure fan offering exceptional operating economy, a number of installation advantages, accurate and troublefree control, plus low maintenance costs.
Fläkt Wood's PFT axial fan is the optimum choice for your next forced draft or induced draft fan.
PFT fan's overall design features make it a unique axial fan and here is why:
The fan's design ensures high aerodynamic performance throughout its entire operation range.
You always choose the optimal fan for your installations due to the large range of PFT models.
No external actuator is needed.
The blades are controlled by a minimum number of moving parts, giving high reliability, low friction and long operating life.
The servo system controlling blade positioning eliminates all hysteresis problems.
The details that make PFT axial's the most economical alternative are:
The control system quickly and accurately adjusts the PFT fans operating point to meet system requirements.
Placing of the blade thrust bearings at a maximum distance from the centre of the impeller enables larger bearings to be used resulting in lower bearing load.
PFT's design principle gives you a fan of the longest possible operating life due to:
A low load bearings.
Guaranteed continuos lubrication of blade thrust bearings under pressure.
No risk for faulting the lubricant.
No corrosion risk.
We have designed from the start to operate over long periods without the need for maintenance, to keep service requirements to a minimum.
