SIF RANGE SIF-700/900/1200/1500/1800/1900/2000 LI/RI Extraction fan with straight blades to be used in central welding fume extraction systems or general filtration systems. It is mounted in a sound absorbing case with inspection cover either left (“LI” type) or right (“RI” type). The fan is equipped with flexible inlet and outlet adapters and placed on shock absorbers. In case it is combined with a central filter unit, the fan has to be connected to the outlet side of the filter unit. product data sheet APPLICATIONS The fan is intended to be used in the following configurations: ––multiple arm systems ––modular extraction hood systems ––push-pull systems SPECIFICATIONS Physical properties Material: • fan • housing Options and accessories Mounting frame refer to table on page 3 Silencer (straight or elbow refer to table on page 3 90°) SIF outdoor; fans suitable for outdoor installation (rainresistant) Outdoor kit consists of: • rain cover over sound absorbing case, including coupler for duct or silencer • ventilation grids provided with rain cover • seams of the absorbing case being fully sealed (except for the inspection cover) SIF outdoor • -20°C (-4°F) • 20°C (68°F) • 60°C (140°F) • steel • steel with aluminium profiles and corners Motor design Discharge position Design conditions Extraction fan in sound absorbing case - Key - Strain relief Noise level according to ISO 3746 (fan without sound absorbing case) refer to attached fan curves Noise reduction sound absorbing case Scope of supply Order information Number/package Electrical data Harmonized Tariff Code Connection voltage Insulation class Protection class Directive 2011/65/EC (RoHS) valid as of 8 June 2011 Storage conditions Ambient conditions
