Automatic air vent with magnet and filter screen IVAR.NEOVENT LHF – 5/4" F, horizontal
Code: 502328Product detailed description
IVAR.NEOVENT LHF 5/4" F (code 502328) is an air vent with magnet and filter screen for horizontal connection with a 5/4" female thread. The filter cartridge sets the flowing water into a vortex in which microbubbles are released. These cling to the structure of the cartridge, gradually grow and finally rise to the upper NEOVENT M valve, which releases them. De-aerated water circulates quietly and the system is less exposed to corrosion and mechanical damage.
What it consists of
- NEOVENT M air vent valve with automatic and manual mode
- star-shaped air bubble separator and 800 µm filter screen, replaceable if clogged
- magnet with 12 000 Gauss magnetic induction and drain valve for desludging
- brass connecting tee, clip and vent body
- materials: brass CB753S and CW617N, EPDM seal, AISI 304 stainless steel
Hydraulics of the 5/4" size
For this size the manufacturer states a flow coefficient Kv of 41.6 m³/h and a maximum flow of 4300 l/h. The unit operates at up to 10 bar and at 0 °C to +110 °C, with water or a water/glycol mixture up to 50 %.
Installation
The best location is after the heat source on the suction side of the pump, where most microbubbles form. The body must always stand vertically and the pipe connections must be horizontal; observe the flow direction marked by the arrow on the body.
Maintenance
Before inspection or cleaning, switch off the heat source, close the ball valves upstream and downstream of the unit and wait for it to cool – hot water can cause burns. During the heating season, remove the magnet every three months and open the drain valve for a few seconds to flush settled dirt out of the settling chamber. Carry out complete disassembly with rinsing of the filter screen under running water for the first time one month after installation and then at least every six months.
Flush the system before commissioning – IVAR recommends treatment with GEL.LONG LIFE 100.

Frequently asked questions
Where should the IVAR.NEOVENT LHF 5/4" be installed?
Ideally after the heat source on the suction side of the pump, where most microbubbles form. The body must be vertical, the pipe horizontal and the flow in the direction of the arrow on the body.
How often does the unit need cleaning?
During the heating season, desludge it through the drain valve every three months after removing the magnet. Carry out complete disassembly with rinsing of the screen one month after installation and then at least every six months.
What flow can the 5/4" size handle?
The manufacturer states a maximum flow of 4300 l/h and a Kv of 41.6 m³/h. The operating pressure is up to 10 bar and the temperature 0 °C to +110 °C.
Can I use the unit with an antifreeze mixture?
Yes, the medium can be water or a water/glycol mixture with a concentration of up to 50 %. The unit is designed for both 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.
