BLR CENTRIFUGAL ELECTRIC BLOWERS

BLR CENTRIFUGAL ELECTRIC BLOWERS

Product catalog summary

Description and Use
Centrifugal electric blowers are designed for high efficiency, capable of handling large volumes of clean or slightly dusty air at temperatures up to 60°C. They are commonly used on ships for air suction and ventilation in enclosed spaces such as bathrooms, kitchens, and engine rooms.

Construction Features
The blowers feature a spiral casing made of painted steel and a fan with steel backward curved blades that are dynamically and statically balanced.

Electric Motor
The blowers use an induction electric motor available in single-phase (230V) and three-phase (230-400V/400-690V) configurations, operating at 50Hz with protection ratings of IP54-55 and insulation class F for continuous duty (S1).

Orientation
The orientation of the blower must be specified when ordering, with options for right direction (RD) and left direction (LD), viewed from the motor side.

Performance
The document provides detailed performance specifications for various models, including voltage, power, absorption, RPM, noise level (dBA), maximum delivery (m3/min), and maximum pressure (mmH2O). For example, the BLR 40/2 A model operates at 230-400T voltage, with a power of 5 HP, and delivers up to 120 m3/min at a maximum pressure of 208 mmH2O.

Dimensions and Weights
Dimensions and weights for each model are provided, including measurements for motor support and inlet/outlet flanges. For instance, the BLR 40/2A model has dimensions of 147 mm (A) x 668 mm (B) x 655 mm (C) and weighs 96 kg.
