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.
