Automatic air vent with magnet and filter screen IVAR.NEOVENT LHF – 6/4" F, horizontal
Code: 502329Product detailed description
IVAR.NEOVENT LHF 6/4" F (code 502329) is an air vent with a magnet and filter screen for horizontal connection with an internal thread of 6/4". The filter insert swirls the flowing water into a vortex, from which microbubbles are released. These bubbles are captured by the structure of the insert, gradually grow larger, and finally rise to the top valve NEOVENT M, which releases them. The deaerated water circulates quietly, and the system is less prone to corrosion and mechanical damage.
What it consists of
- air vent NEOVENT M with automatic and manual mode
- star-shaped air bubble separator and filter screen 800 µm, replaceable when clogged
- magnet with magnetic induction 12 000 Gauss and discharge valve for sludge removal
- brass T-piece, bracket, and deaerator body
- materials: brass CB753S and CW617N, sealing EPDM, stainless steel AISI 304
Hydraulics for size 6/4"
For this size, the manufacturer specifies a flow coefficient Kv of 57.4 m³/h and a maximum flow of 5900 l/h. The device operates at a pressure up to 10 bar and a temperature of 0 °C to +110 °C, with water or a water-glycol mixture up to 50%.
Installation
The best location is behind the heat source on the suction side of the pump, where the most microbubbles are formed. The body must always be vertical, and the pipe connections must be horizontal; follow the flow direction indicated by the arrow on the body.
Maintenance
Before inspection or cleaning, turn off the heat source, close the ball valves in front of and behind the device, and wait until it cools down – hot water can cause burns. During the heating season, remove the magnet and briefly open the discharge valve every three months to flush out accumulated dirt from the sedimentation chamber. A complete disassembly and cleaning of the filter screen under running water should be done one month after installation and then at least once every six months.
Flush the system before starting – IVAR recommends treatment with the preparation GEL.LONG LIFE 100.

Frequently asked questions
Where should IVAR.NEOVENT LHF 6/4" be installed?
Best behind the heat source on the suction side of the pump, where the most microbubbles are formed. The body must be vertical, the pipe horizontal, and the flow in the direction of the arrow on the body.
How often should the device be cleaned?
During the heating season, clean it every three months by removing the magnet and discharging through the outlet valve. A complete disassembly and cleaning of the screen should be done one month after installation and then at least once every six months.
What flow rate can size 6/4" handle?
The manufacturer specifies a maximum flow of 5900 l/h and a coefficient Kv of 57.4 m³/h. The operating pressure is up to 10 bar, and the temperature is 0 °C to +110 °C.
Can the device be used with a non-freezing mixture?
Yes, the medium can be water or a water-glycol mixture with a concentration up to 50%. The device is suitable for heating and cooling systems.

IVAR designs, develops and manufactures highly energy-efficient heating and plumbing systems. We have over 10,000 catalogue items - mass-produced products and unique items - in addition to customised systems and combinations of complex products. And it’s all “Made in Italy”.
Vision
To make life easier for our clients, our clients' customers and our employees, thanks to our ability to be constantly innovative.
Mission
To design and manufacture advanced hydronic solutions that reduce installation complexity and energy consumption.
“Made in Italy” adds value
IVAR has been producing heating and plumbing system components since 1985: valves for heating bodies, direct heat metering modules, heat cost allocators, pipes and fittings, substations for heating systems, distribution manifolds, radiant panel systems, and components for solar and geothermal systems. And it’s all “Made in Italy”.
Over 200 people are employed at our manufacturing facilities in Prevalle (in northern Italy’s Brescia province). The site has been designed to streamline our many production and operational stages.
The Italian headquarters also acts as a hub for the wider IVAR Group, set up with the goal of distributing products beyond Italy’s borders. The group now has 11 branches, in Australia, Belgium, China, Germany, the United Kingdom, the Czech Republic, Romania, Slovakia, Spain, the United States and Tunisia.
Know How
Research, development and numerous laboratory tests guarantee that our clients’ requests can be translated into new high-efficiency products.
The stages required for production take place internally, beginning with hot forming, which is carried out at our subsidiary Valmon Stampati. Our continuous implementation of projects under the Industry 4.0 initiative also allows us to take full advantage of new releases in technology and IT to improve our manufacturing efficiency.
As a company, IVAR is constantly evolving. Every day, we invest in strengthening our products, in improving our production processes and in attaining new patents and certifications.
