Square Inline Centrifugal Fan SILC Moduflow features
- Galvanised construction for internal or external use and no need to paint
- Motors positioned outside airstream
- Cleaner motor operation increasing lifespan
- Speed controllable
- Ideal for ducted systems
The backward curved in-line centrifugal range of fans consists of 17 duty sizes with a maximum air flow of 16m3/s and static pressures in excess of 2000 pa. The impellers are of high efficiency powder coated steel construction. Driven by Tefc. IP55. class F motors as standard. The motors are outside the ventilation airflow path. The units are capable of high temperature operation.
Always handle the units carefully to avoid damage and distortion. Care must be taken to ensure that any slings used for hoisting do not damage the casing.
Installation must be completed by competent persons in accordance with good industry practice and should conform to all governing and statutory bodies, ie. IEE,CIBSE, COHSE etc. The units can be installed both horizontally or vertically and are suitable for internal or external applications. The unit is flanged at both ends and can be bolted directly to the system duct or mounted on optionally available feet and anti-vibration mounts. The method chosen is the responsibilty of the installer.
Check that the fan details on the rating plate correspond with the supply voltage and frequency.SILC Square Inline Centrifugal F Motor overloads should be set to the full load current on the rating label. Supply fuses should be H.R.C type.
Start Up Proceedure
The single phase rotational direction is set at works and should not be altered. For 3 phase units, check that the rotation is correct; if not, interchange any two phases. The equipment should be run for approximately 30 minutes to ensure correct operation. If a fault occurs, switch off. DO NOT restart until fault has been rectified.
