Diaphragm aerators ø 100/110 mm images
Diaphragm aerators ø 100/110 mm
PVC membrane vent Ø 100/110 mm for waste water drainage
This membrane aerator (also known as a vent valve or anti-vacuum valve) allows air to enter a drainage pipe when water is flowing, to prevent traps from emptying (de-aeration). When not in use, the diaphragm closes, limiting the rise of odours.
Female socket Ø 100 mm or male spigot Ø 110 mm – PVC body for gluing – NBR diaphragm – removable screw cap.
Sold individually.
Description
Introduction to the membrane aerator
When water drains away (from a sink, washing machine, shower, toilet, etc.), the falling water creates a vacuum in the pipework. Without a supply of air, this vacuum can draw water out of the traps: they empty and sewer odours rise up. The membrane aerator solves this problem: the membrane lifts to let air in, then drops back down as soon as the flow has stopped.
It is usually fitted at the end of a pipe, at the top of a downpipe or main drain, in an accessible location.

Applications
- ventilation of a PVC waste pipe or manifold with a diameter of 100 mm or 110 mm;
- installation at the end of a pipe, above connected appliances (showers, sinks, washing machines, dishwashers, etc.);
- replacement of an existing diaphragm vent of the same diameter.
ℹ️ Good to know
The 100 and 110 mm diameters refer to the external pipe diameters. The same fitting can be used in two ways: either by sliding a Ø 100 mm pipe inside it, or by gluing the vent into a Ø 110 mm female connector. The aerator must be installed vertically, with the cap facing upwards, to ensure the membrane functions correctly. Depending on your installation, check the regulations applicable to drain ventilation (DTU 60.11).
⭐ Tip from the team
Place the vent in an accessible, well-ventilated location (not inside a closed casing): it must be able to draw in air and be removed. To fit it, cut the elbow pipe to size, deburr, clean and then bond it using PVC adhesive. The cap can be unscrewed to inspect or clean the membrane.
❓ Frequently asked questions
What type of pipe is this vent fitted to?
On a Ø 100 mm PVC drainpipe (slid into the vent) or in a Ø 110 mm female connector (the vent is inserted into it). It is fitted using adhesive.
Which way round should it be installed?
Vertically, with the cap facing upwards, at the highest point of the pipework.
Can it be maintained?
Yes: the screw-on cap can be removed to inspect and clean the membrane.
What is it made of?
The body and cap are made of PVC, and the membrane is made of NBR rubber.
