Dust Filters

Dust filters have the function to stop dust particles in the gas pipeline. The fineness of the filter element determines which particles are collected. Coarse filters are mesh filters that have the function of, for example, stopping welding slag (filtering). To filter finer (dust) particles, filter fineness size 1, 3, 5 and 10 micron is required The BD-Gas dust filters are small dust filters that are very suitable for smaller gas installations. Some dust filters can be combined with a safety Relief unit.

Dust filter type DF

A DF filter is a dust filter with a filter fineness of 5-10 microns. The dust filter is available with a connection of 3/4 “, 1” BSP-Tr screwed and DN25 PN10 / 16 flanged. This type of filter can also be combined with a safety Relief unit (FOPSO).

The maximum working pressure = 8.6 (19.6) barg. Capacity up to 50 Nm3/h.

Dust filter type FL

A FL filter is a dust filter with a filter fineness of 3-5 microns. The dust filter is available with a connection of 3/4 “, 1” BSP-Tr screwed and DN25 PN10 / 16 flanged.

The maximum working pressure = 8.6 (19.6) barg. Capacity up to 100 Nm3/h.

Pilot filter

A pilot filter is often used as a dust filter for regulator equipment with fine or delicate mechanics. It is a small filter with a filter fineness of 3-5 microns. The connection is 1/4 “NPT.

The maximum working pressure = 100.0 barg. Capacity up to 250 Nm3/h.
