Regardless of presumably high efficiency, the degree of efficiency varies with two significant aspects.

These include the particle size of the contaminants and the technical specifications of the machine.

Fuel gas filter system

For most filtration units, the efficiency level varies according to the contaminant sizes.

It means that when you are dealing with an outrageously impure gas majorly comprising of fine particles, expect the efficiency of the machine to decrease.

Conversely, the effectiveness of the filter tends to increase when filtering large-sized particles.

Most importantly, to verify the efficiency of the machine always seek reference to the technical specifications of the equipment.

Despite all that, some filters will still have varying practical efficiencies even under constant application and possession of similar technical specifications.

Also, the double design structure of the filter offers a large surface area for filtration, which thus exhibiting a massive filtration scope.

Besides, the dual chambers function independently during filtration.

It, therefore, means that even if one compartment breaks down, you simply switch operation to the other standby chamber for continued service.

Normally, the duplex filter thus guarantees continuous filtration operations no matter the situation without any lapse.

Ultimately, the filter configurations do not allow any slight downtime during maintenance or basket screen cleaning.

Above all, the changeover between the chambers is a straightforward process.

You instantly change over with a single operation or by even turning the levers.

The duplex filter configurations also have got a diverter plug that allows the flow medium to flow either through the right or left chamber.

· Simplex Fuel Gas Filters

Simplex gas filter system

Unlike the duplex configurations, the simplex configuration is a type of filter that consists of one primary unit chamber for filtration operation.

The simplex structure is simple without any kind of sophistication.

Here, the fuel gas majorly flows via the single chamber while the contaminants get trapped and eliminated; after that, the pure gas proceeds.

Due to the design consideration, the filter elements are easy to remove and replace.

Also, the simplex configurations filters are also available into two major filter types, i.e., basket type filters and the Y-type filters.

Which is the Best Material for the Fuel Gas Filter?
