Yard inlet Perfekt DN110 with vertical outlet, connection flange, 260x260mm cast iron frame, 226x226mm cast iron drain grate, water siphon and sediment basket HL616.1W/1

Stormwater drainage with performance and durability

This Perfekt yard inlet, designed for effective stormwater drainage, is suitable for both parking lots and courtyard areas. Made of durable cast iron, it guarantees long-lasting reliability even under heavy loads – B125 class allows for vehicles weighing up to 1.25 tons. The design with a vertical outlet facilitates integration with the sewage system.

Construction and functionality

The inlet is equipped with several key elements that enhance its functionality and facilitate installation:

• Connection flange: allows for a tight connection with the waterproofing layer, especially when used with the HL86 series sealing kit. This is crucial for ensuring the integrity of the system and preventing leaks.
• Adjustable height: the frame with a cast iron grate is adjustable in the range of 60-125mm, allowing it to be adapted to different installation conditions and surface heights.
• Water trap: provides effective protection against unpleasant odors – ideal for use in areas with positive temperatures.
• Sediment basket: retains larger debris, preventing clogging of the sewage system and facilitating its maintenance.
• Flow rate: the water drainage efficiency is 2.10 l/s, ensuring rapid removal of rainwater even during heavy rainfall.

Versatility and expandability

This inlet is not only a ready-made solution but also an element of a modular drainage system. The possibility of using additional elements:

• Straight and flanged extensions (HL620, HL618(H)) and drainage ring HL190 allow the drainage to be adapted to the specifics of the roof structure layers.
• The option of equipping with a heating kit HL609 enables the use of the inlet in areas exposed to freezing.

This makes the investment flexible and can be adapted to changing needs. It is also worth mentioning the possibility of tightly integrating the inlet into the waterproofing layer – a feature particularly appreciated by professionals in the implementation of construction investments.
