The Altecnic Dirtmag Mini™ is a compact magnetic dirt separator and strainer designed for easy installation under wall-mounted boilers, without the need for additional accessories. Despite its ultra-compact design, Dirtmag Mini does not compromise on features, performance or versatility. It combines magnetic filtration, dirt separation and flexible installation in a single space-saving unit.

Why is space becoming a challenge for heating installations?

Over the last decade, the average size of new-build homes has decreased as developers look to use space more efficiently. This has had a knock-on effect on the plumbing and heating industry, with installers increasingly needing to source space-saving products.
For installers working beneath wall-mounted boilers, every centimetre counts. A filter must fit the available space while still protecting key heating system components.

How does the Dirtmag Mini filter heating system debris?

The compact Dirtmag Mini™ combines severalfiltration and separation processes to capture different types of debris. This combined approach helps protect the boiler circulator and heat exchanger from system impurities.

The Dirtmag Mini combines:

● Magnetic separation: the powerful internal magnet captures ferromagnetic particles.
● Straining: an 800 μm mesh captures non-magnetic residues such as sand, soldering residues and sealant debris.
● Dirt separation: the collection chamber slows the system fluid, allowing smaller particles to settle.

This makes the Dirtmag Mini more than just a magnetic filter. It combines magnetic particle capture with mechanical filtration and dirt separation in a single compact unit.

Can a magnetic filter be installed horizontally or vertically?

Yes. The Dirtmag Mini is designed for flexible installation, with a special inlet that allows for horizontal or vertical installation, with angled or in-line connections as required. Its interchangeable pipe connections use a quick-fit system with fixing clips to make changing configuration straightforward.

This flexibility can be particularly useful where space around a wall-mounted boiler is restricted or where the existing pipework dictates the filter's orientation.

Is the Dirtmag Mini easy to maintain?

The Dirtmag Mini has a self-cleaning function that allows installers to drain collected debris without opening the main filter body. By removing the magnet and opening the drain cock, system debris can be flushed out using the system water.

The unit also incorporates full-bore isolation valves, making servicing easier. If the strainer screen becomes clogged with larger particles, it can be removed and cleaned separately.

What are the key features of the Dirtmag Mini?

The Dirtmag Mini has been developed to combine compact dimensions with the features installers need in a heating-system dirt separator.
● Ultra-compact design for installation in confined spaces.
● High-performance removable magnet with 1.3 T magnetic induction.
● 800 μm filter mesh for capturing non-magnetic debris.
● High-strength technopolymer dirt separator specifically selected for heating and cooling system applications.
● Horizontal or vertical installation with interchangeable connections.
● Angled or in-line configurations for greater installation flexibility.
● Self-cleaning function to simplify debris removal.
● 22 mm compression connections for use with suitable copper tube.

Where should a magnetic dirt separator be installed?

The Dirtmag Mini should be installed in the return circuit to help protect the boiler from debris circulating through the heating system, particularly during system start-up. It can be installed horizontally or vertically, provided the drain cock is positioned appropriately, and the flow direction shown on the valve body is followed.

Dirtmag Mini: The perfect choice for compact installations

When space is limited, a heating system filter needs to do more than simply fit. The Dirtmag Mini combines magnetic filtration, dirt separation, straining and self-cleaning in a compact unit designed specifically for under-boiler applications.

With flexible horizontal, vertical, angled and in-line installation options, it gives installers greater freedom when working around restricted pipework and limited installation space.

Frequently asked questions

What are the dimensions of the Dirtmag Mini?

The Dirtmag Mini is designed as an ultra-compact filter for installation in confined spaces, including beneath wall-mounted boilers.

What is the maximum working pressure and temperature?

The Dirtmag Mini has a maximum working pressure of 3 bar and a working temperature range of 0°C to 90°C. It is designed for water and non-hazardous glycol solutions, with a maximum glycol concentration of 30%.

What are the benefits of using technopolymer for the dirt separator?

The technopolymer offers high strength, crack and erosion resistance, low water absorption and reliable performance across temperature variations. It is also compatible with glycols and system additives, providing durable performance comparable to traditional metal dirt separators.
