LORO-X Series 49 DRAINJET siphonic drainage with standard hood
Large roof areas can be drained economically and safely using high-performance siphonic drainage systems.
LORO-X rapid drainage systems with siphonic flow operate with smaller pipe diameters at higher flow velocities while achieving greater drainage capacity. The high flow velocity in the pipe also increases the self-cleaning effect.
Further application examples with detailed descriptions can be found in our LORO-X DRAINJET rapid drainage systems brochure (Aktuell 172.pdf).
LORO-X DRAINLET for gravity drainage can be found here.

LORO-X gravel guard basket for LORO-DRAINJET®/DRAINLET® flat roof drains
For roof structures with an elevated gravel layer, LORO offers a new 180 mm high gravel guard basket as a supplement to the standard height of 80 mm.
Both gravel guard baskets can be mounted on LORO DRAINLET and DRAINJET flat roof drains.
They feature an all-round slot size of 10 mm, preventing the ingress of gravel from a size of 10 mm.
Since the LORO hoods have a larger all-round slot size of 15 mm, clogging of the drain inlet openings is prevented and drainage is permanently secured.

• Suitable for DRAINLET (Series 84) and DRAINJET (Series 49) flat roof drains
• Suitable for main and emergency drainage• Protection against objects from 10 mm in size
