G3 WASHABLE POCKET FILTER

Thermo-welded synthetic fibre bag filter class G3 according to EN 779:2002 (80% ≤ Em < 90%). Available in two variants of bags (D = 360 mm and D = 500 mm) enables high dust holding capacity (DHC).

APPLICATION

Filtration of course airborne particles, in civil and industrial air conditioning systems. It is commonly also used as pre-filtration stage before the fine dust filters.

OPERATING RANGE

Maximum temperature: 90 °C (continuous operation -80°C)

Relative humidity: 100%

Recommended final pressure drop: 250 Pa

FILTER MEDIA

Layered progressive density synthetic fibre.

Filter media colour – Green

TECHNICAL INFORMATION

PERFORMANCE

• The average efficiency shall be as determined by the ASHRAE Standard 52.1 and 52.2 test methods.

• Media provides a high dust holding capacity and long service life.

• Pocket filters without a pre-filter will require replacement more frequently.

• The media incorporates a uniform high loft to provide a lower resistance to airflow.

• Available with different efficiencies and in different sizes to meet individual requirements.

• Reduction of energy costs due to low initial differential pressure

• Filters should be installed with pockets in the vertical wherever possible.

GUIDELINES WHEN SELECTING A POCKET FILTER

• Determine the ASHRAE efficiency required.

• Determine the face velocity needed to fit the system.

• Select the shortest depth possible with a pressure drop within the required range.

• Select the most economical filter based on the number of pockets per 600 x 600mm size.

• Initial and final resistance shall not exceed the scheduled values.
