The LM series combines the typical advantage of helical fans of being able to transport air on the same axis as the impeller with the high efficiencies of a centrifugal impeller. - Ideal for 'installation on hoods and small civil and industrial extraction systems, they are characterized by low noise and discrete heads. The limited overall dimensions and normalized suction and pressure ports make the installation of this series particularly easy. Suitable for conveying clean air at a maximum temperature of 40 °C.
CIMI Srl reserves the right to change dimensional dimensions and/or performance for improvements or range changes without what is on the site being binding.
The reported data meet the following parameters:
- Tolerance on flow rate ±5%
- Noise tolerance +3dB(A)
- Air temperature 15°C
- Barometric pressure 760 mm Hg
- Air specific gravity 1.226 kg/m³
- Frequency 50 Hz
Sound pressure level was measured by omnidirectional free-field measurement at 1.5 or 3 m (depending on the product) from the fan with ducted inlet, tolerances, performance points and environments according to European standards.
