Automatic air separator - 6/4" IVAR.DISCAL 551

Product detailed description

Automatic air separators are essential components in closed heating systems, particularly in residential and commercial buildings with central heating installations. These devices are installed in radiators, underfloor heating manifolds, and boiler circuits to ensure continuous removal of entrained air. Installers working on multi-zone systems or large-scale heating networks frequently encounter the need for efficient air separation to maintain system efficiency and prevent airlocks. The device is typically mounted in vertical or horizontal positions depending on the system layout and accessibility for maintenance.

Correct installation and sizing of air separators are critical for system performance. The device must be positioned to allow free access for inspection and to ensure that air can be effectively drawn from the system. In multi-pipe systems, it is common to install air separators at key points such as the return line or at the end of each circuit to ensure complete air removal. The operating conditions, including temperature and pressure, must be compatible with the system requirements to avoid premature failure or inefficiency.

Technical parameters

Installation and connection

Installation should be carried out in accordance with the manufacturer's guidelines. The device is connected using standard 6/4" pipe threads, and it is important to verify that the thread type matches the system piping. A common mistake is incorrect orientation of the device, which can prevent proper air removal. Installers should ensure that the device is mounted in a location that allows for easy access to the air vent and that the surrounding area is free from obstructions. It is also important to check that the system pressure does not exceed the PN 10 rating to avoid mechanical stress on the device.

Compatibility and accessories

This air separator is compatible with standard heating systems that operate within the specified temperature and pressure ranges. It is typically used in conjunction with pressure-reducing valves, expansion vessels, and circulation pumps. No additional accessories are required for standard installation, but it is recommended to check the system design to ensure that all components are properly integrated. No related products are available for this model.

Technical background for designers

The operating principle of the device is based on the continuous removal of air from the system through a self-acting valve mechanism. The CW617N brass body provides good thermal conductivity and resistance to corrosion, while the stainless steel internal components ensure durability in high-temperature environments. The device is designed to integrate seamlessly into closed heating systems, and its performance is influenced by factors such as system flow rate, air content, and operating pressure. Proper sizing is essential to ensure that the device can handle the expected air load without causing flow restrictions or inefficiencies.

Service and operation

Regular inspection of the device is recommended to ensure that it is functioning correctly. Installers should check for signs of blockage or wear on the internal components and verify that the air vent is operating as intended. No specific service intervals are provided, but any visible damage or performance issues should be addressed promptly. The device requires no routine maintenance beyond visual inspection and cleaning of the vent area if necessary.

Frequently asked questions

Can this air separator be used in high-temperature radiant floor heating systems?
Yes, the device is rated for a maximum operating temperature of +110°C, making it suitable for high-temperature radiant floor heating systems that operate within this range.

Is this model compatible with stainless steel piping?
Yes, the brass construction is compatible with stainless steel piping, and no special sealing materials are required for the connection.

Can the device be installed in a horizontal position?
Yes, the device can be installed in either vertical or horizontal positions, provided that the air vent is accessible and the system allows for proper air removal.

What is the maximum pressure rating of the device?
The device is rated for PN 10 pressure, which means it can operate safely in systems with a maximum pressure of 10 bar.
