Function and design

Effectively catches the solid particles which are bigger than the strainer insert mesh when the meda is passing through the cylindrical insert.

Technical information

Kv_v-value applies to a clean strainer insert with a standard mesh width of 0,6 mm.

Accessories and options

The insert gaskets standard mesh width is 0,6 mm. On request, the strainer can be provided with alternative mesh sizes, such as:
0.1, 0.25, 0.5, 1.0, 1,5, 2.0, 3.0, 5,0 and 8.0 mm.

Internal and external powder-coated epoxi is used for installations with hygiene requirements for water intended for human consumption or where there is a requirement for internal corrosion protection: AT 4028BE,

For differential pressure measurement across the filter, strainer DN 15-32 connection G 1/4. DN 40 and larger have connection G 3/8. See AT 1812.

For installation in cooling systems, the filters are available with external rust-preventing, according to system AT 1012.

Installation

In a horizontal pipe the strainer should be mounted with the cover downwards. Not that the flow has to be according to the flow arrow. The strainer can be vertically mounted with a downwards flow.

A blow-out valve, e.g. AT 3535A or AT 3591, can be mounted instead of a clean-out plug for an easier purge of the strainer insert.

Maintenance and spare parts

Highly increased pressure drop across the filter indicates that the strainer insert should be cleaned.
Strainer inserts AT 4028AF and cover gaskets AT 4028AL and AT 4028BL are available as spare parts.
