DIRTMAG

dirt separator with magnet, adjustable for

vertical or horizontal pipe

NA5453 Series

Function

In heating and chilled water systems, the circulation

of water containing impurities may result in rapid

wear and damage to components such as pumps

and control valves. It also causes blockages in heat

exchangers, heating elements and pipes, resulting in

lower thermal efficiency within the system.

The dirt separator separates off these dirt particles,

circulating within the closed circuit system. These

particles are collected in a large chamber, requiring

infrequent cleaning, which requires simply removing

the magnet ring and opening the large drain valve

while the system is running. This device is capable of

efficiently removing particles to a very small size, with

very low pressure head loss.

The DIRTMAG

magnetic dirt separator removes

both ferrous and non-ferrous impurities continuously,

featuring a powerful removable external magnet

around the body that removes up to 100% of the

ferrous impurities, including magnetite, that can

form in a hydronic system. The DIRTMAG

has 2½

times the removal performance of a standard dirt

separator. The body of the NA5453 series separator

is made of glass reinforced nylon specifically

designed for use in heating and cooling systems. It

also is especially versatile as it can be installed on

either horizontal or vertical piping with the rotating

brass base mount.

The NA5453 series is available with conventional union NPT and union sweat union connections

and the Presscon™ press copper tail-piece with union nut that makes installation and maintenance

fast, easy and efficient. Special slots in the EPDM O-ring allows fluid to leak during system testing

if unpressed and provide a perfect leak proof seal when completely pressed. Also, models are

available with isolation inlet and outlet shutoff valves, which can be used as a dosing point to inject

chemical additives into the hydronic circuit.

These items are designed for use in closed hydronic systems. Do not use in plumbing applications. These

items do not meet the low-lead plumbing standards of U.S. and Canada.
