Automatic air vent with filter screen IVAR.NEOVENT MM – 1/2" M
Code: 502308Product detailed description
IVAR.NEOVENT MM 1/2" M (code 502308) is an air vent valve that continuously removes air from hydraulic circuits – according to the manufacturer down to microbubble level and with very low pressure loss. De-aerated water circulates quietly, the risk of corrosion and mechanical damage is reduced and the system runs at optimum performance. The valve connects via a 1/2" male thread.
Code 502308 is supplied with a flow-deflecting insert that improves the separation of air bubbles from the system.
Design
- float-type automatic valve and manual vent valve in one body
- filter screen with 500 µm porosity and a star screen for bubble separation
- replaceable cartridge in case of clogging
- filter body adjustable by 360° rotation
- brass CW617N, EPDM seal, AISI 304 stainless steel
Three operating modes
- automatic – normal operation, the valve releases accumulated air by itself
- manual – when filling the system; the valve must be supervised during this phase
- closed – during a pressure test of the system with air
Installation and maintenance
The valve is designed for heating, cooling and domestic hot water systems with water or a water/glycol mixture up to 50 %. For correct operation, install it vertically at the highest point of the system. Carry out the first thorough cleaning with complete disassembly one month after installation, then at least once a year. Let the water cool before any work – hot heating water can cause burns. Flush the system before commissioning; IVAR recommends treatment with GEL.LONG LIFE 100.

Frequently asked questions
Where is the IVAR.NEOVENT MM air vent installed?
Vertically at the highest point of the system, where air collects. The filter body can be rotated by 360°, so it can be adapted to the available space.
Which mode should I use when filling the system and during the pressure test?
Use manual mode when filling and keep the valve under supervision. Switch it to closed for a pressure test with air and leave it in automatic mode during normal operation.
How often does the valve need cleaning?
Carry out the first thorough cleaning with complete disassembly one month after installation, then at least once a year. If the filter cartridge clogs, it can be replaced.
Can the valve be used in a system with glycol?
Yes, the manufacturer specifies water as well as a water/glycol mixture with a concentration of up to 50 %. The operating temperature is 0 °C to +110 °C at up to 10 bar.

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.
