Compact, portable SRF T models are designed for the connection to welding torches and capture the welding fumes directly at point of origin. The devices can also be used to extract soldering fumes. No subsequent running costs due to the filter cartridges being cleanable. A dust collection drawer enables simple disposal of gathered material. The SRF T-2 is designed for one extraction point; the SRF T-4 for two. Ideal for welding fume extraction on building sites, in shipbuilding, small-part welding work stations or in motor vehicle workshops.
