PBM centrifugal fan
APPLICATIONRadial fan without housing, dedicated to clean or lightly polluted air transport.Examples of use:
∙ air handling units, ∙ drying systems, ∙ recirculation systems, ∙ spray chambers.
CONSTRUCTION ∙ directly driven radial fan, ∙ aluminium impeller with backward curved blades, dynamically balanced
according to ISO 21940-1, ∙ fan adapted to horizontal installation, ∙ aluminium fan with base elements made of steel painted grey RAL
7042, ∙ fan working temperature range from -200C to +400C, ∙ inlet cone equipped with 4 pressure measuring nipples Ø6mm evenly
distributed in inlet circumference near the impeller.
MOTOR ∙ asynchronous, three-phase, 230/400V 50Hz or 400/690V 50Hz, ∙ degree of protection IP55, ∙ insulation class F, ∙ adapted for frequency converter.
SPECIAL EXECUTIONS ∙ colour other than standard, ∙ motor with voltage and frequency of power different than standard, ∙ motor with other than standard degree of protection, ∙ fan working temperature range below -200C and above +400C.
