SISW backward curved belt driven centrifugal fans

PRL-TC

General Description

SISW non-overload backward curved centrifugal fan, sizes are in accordance with AMCA 99-16.

The fans of the PRL-TC series find their main application in commercial and industrial plants of air-conditioning, ventilation, heating and filtering; they can be used as well in industrial processing (baker ovens, spray booths, driers, boilers, silos, cooling systems, etc.).

PRL-TC fans can convey clean or slightly dusty air and smoke with maximum temperature of 180ºC.

Suitable for very high capacities and high pressure:

Airflow range : 3,400 to 84,000 CMH
External static pressure : 200 to 1,400 Pa

Certification

AMCA certified performance for Air, Sound & FEG.

Construction

Volute casing: steel sheet, protected against atmospheric agents by epoxy paint.
Aerodynamically shaped inlet cone in steel sheet, protected against atmospheric agents by epoxy paint.

Impeller

Single inlet single width backward curved wheel with high efficiency at higher pressure gradient, manufactured in steel sheet and protected against atmospheric agents by epoxy paint.
For high rotational speed, versions in class III are foreseen.
Mono-block support in cast iron with ball bearings, designed for easy lubrication for L10 life more than 100,000 Hr.

Motor

Asynchronous three-phase motors according to international standards IEC 60034, IEC 60072, IP 55, class F, (continuous working at constant load), suitable to S1 service.
