Frequently asked questions
What systems is it compatible with?
For dust extraction systems with piping diameter matching the product specifications.
Check connection diameters before purchase. Krollit provides standard accessories for main diameters (Ø100, Ø120, Ø150).
Does it reduce pressure drops?
Yes, correctly sized fittings and bends reduce losses and improve efficiency.
90° bends cause greater losses compared to gentle bends or Y-branches. Prioritize direct paths.
What material is it?
Typically galvanized sheet metal or rigid plastic material for industrial use.
Galvanized sheet metal components are suitable for abrasive dusts (hardwood), plastic ones for light dusts and standard industrial environments.
Can it be connected to extractors from other brands?
Yes, if the connection diameter matches. Check compatibility in the technical sheet.
Standard diameters are universal among European brands. For non-standard connections, dedicated adapters are needed.
What is needed for assembly?
Typically hose clamps and silicone or gaskets to ensure a seal.
For permanent metal systems, self-tapping screws and silicone sealant on joints are used. For removable systems, use screw clamps.
