Frequently Asked Questions
What systems is it compatible with?
For extraction systems with piping diameter matching the product specifications.
Verify connection diameters before purchase. 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 bends or Y-branches. Prioritize direct paths.
What material is it?
Typically galvanized steel sheet or rigid plastic material for industrial use.
Galvanized steel 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. Verify compatibility in the technical data sheet.
Standard diameters are universal among European brands. Non-standard connections require dedicated adapters.
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 sealing on joints are used. For removable systems, use screw clamps.
