RL blowers are used for applications where dusty and polluted air has to be removed.
The fan is suitable for handling air up to 60°C
These fans are used in industry were great air volumes at high pressure are needed
A protection hood is required for uitside use
Composition
The casing is of a rigid construction in enamelled sheet steel, painted in epoxy RAL 5010 with a total thickness of 90µ - The strong base frame support the motor
The impeller with backward curved blades is dynamically and statically balanced grade G6.3 according to ISO 1940/1 and have efficiencies up to 85%
They have a non-overloading power characteristic which means that they can be use at free inlet duty
Totally closed squirrel-cage asynchronous motor
Protection IP55 – Insulation F
Supply: 230Vac 1ph 50Hz (Steinmetz type) - 230/400Vac 3ph 50Hz and 400/690Vac from 5.5kW motors
Accessories
