Automatic air vent with filter screen IVAR.NEOVENT MF – 1/2" F
Code: 502309Product detailed description
IVAR.NEOVENT MF 1/2" F (code 502309) is an air vent that continuously removes air from hydraulic circuits – according to the manufacturer, even down to the level of microbubbles and with very low pressure loss. The deaerated water circulates quietly, reducing the risk of corrosion and mechanical damage, and the system operates in an optimal performance mode. The valve is connected by an internal thread of 1/2".
Construction
- floating automatic valve and manual air vent in one body
- filter screen with a porosity of 500 µm and star screen for separating bubbles
- replaceable insert in case of clogging
- adjustable filter body rotatable by 360°
- brass CW617N, sealing EPDM, stainless steel AISI 304
Three operating modes
- automatic – normal operation, the valve automatically discharges accumulated air
- manual – during system filling, the valve must be monitored during this mode
- closed – during pressure testing of the system with air
Installation and maintenance
The valve is suitable for heating, cooling and hot water supply systems with water or a water and glycol mixture up to 50 %. In order to function correctly, install it vertically in the highest point of the system. Perform the first thorough cleaning with complete disassembly one month after installation, then at least once a year. Before intervention, allow the water to cool down – hot heating water can cause burns. Flush the system before starting, IVAR recommends treatment with the preparation GEL.LONG LIFE 100.

Frequently asked questions
Where should the IVAR.NEOVENT MF valve be installed?
Vertically in the highest point of the system, where air accumulates. The filter body can be rotated by 360°, so you can adapt it to the space.
Which mode to choose during system filling and pressure testing?
Use the manual mode during filling and keep the valve under supervision. During pressure testing with air, switch it to the closed position, and keep it in automatic mode during normal operation.
How often should the valve be cleaned?
Perform the first thorough cleaning with complete disassembly one month after installation, then at least once a year. If the filter insert becomes clogged, it can be replaced.
Can the valve be used in a glycol system?
Yes, the manufacturer specifies water and a water and glycol mixture with a concentration up to 50 %. The operating temperature is 0 °C to +110 °C at a pressure 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.
