Series 84 DRAINLET with gravity flow

LORO-X DRAINLET flat roof drains for gravity flow are hydraulically optimised with higher discharge capacity, improved flow characteristics, smaller installation dimensions and better acoustic behaviour. Especially for the renovation of conventional flat roof drains, LORO offers a special version as a renovation drain.

Space-saving dimensions

Space-saving dimensions without a “pot” in the roof surface and a high discharge through the LORO-X hood with ventilation openings, optimised for gravity flow, characterise LORO-X DRAINLET® main drainage and emergency drainage with gravity flow.

With ventilation openings

The LORO-X hood functional part is decisive for the reliable functioning of the drainage. On the hoods of LORO-X DRAINLET flat roof drains for gravity flow, the ventilation openings above the inlet openings ensure controlled ventilation at the drain.

Clamping flange for all membranes

Among roofers and specialist dealers, flat roof drains with sealing by means of a clamping flange, consisting of a fixed and a loose flange, are increasingly popular.

Since almost all vapour barriers and roof waterproofing membranes made of bitumen and plastic can be clamped in, stockkeeping at specialist dealers is considerably simplified compared with drains with a pre-mounted connection sleeve: only one drain needs to be stocked for all waterproofing membranes!

The drain is installed recessed into the substrate so that it is flush with the level to be drained. LORO-X DRAINLET and DRAINJET drains are characterised by minimal thermal bridges, as no large "drain pot" has to be inserted into the insulation.

Main drainage and emergency drainage

The emergency drain with integrated damming element is installed at the same level as the main drain, so that elaborate structural measures for "raising" it are not necessary.

High discharge

With a discharge of up to 10 l/s, they are among the drains with high discharge capacity for gravity flow. Together with LORO-DRAINLET® emergency drains, whose use is prescribed by DIN 1986-100 for drainage systems with gravity flow, the drains, in combination with a versatile range of pipes and fittings, form a complete roof drainage system that meets the highest demands.
