Frequently asked questions
What systems is it compatible with?
For dust extraction systems with piping diameters corresponding to the product specifications.
Check connection diameters before purchasing. Krollit provides standard accessories for main diameters (Ø100, Ø120, Ø150).
Does it reduce pressure losses?
Yes, correctly sized fittings and bends reduce losses and improve efficiency.
90° bends cause greater losses than gentle curves 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 indicated 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 data sheet.
Standard diameters are universal among European brands. For non-standard connections, dedicated adapters are needed.
What is needed for installation?
Typically hose clamps and silicone or gaskets to ensure a seal.
For permanent metal systems, self-tapping screws and silicone sealing at the joints are used. For removable systems, use screw clamps.
