Getting to know something of Bag Air Filters

Product Overview

Medium Efficiency Bag Filter is a key filtration equipment in HVAC, cleanroom and industrial ventilation systems, mainly used to intercept dust, pollen, mould spores and other particles of 1-10μm. Its efficiency range covers class F5-F9 (EN 779:2012 standard), which is suitable for medium level air purification requirement scenarios.

Core features and advantages

  • Bag structure design: the number of bags can be customised according to customers' requirements. The bag design increases the filtering area, reduces wind resistance and prolongs service life.
  • Size customisation: support non-standard size.
  • Frame material: galvanised steel, aluminium alloy or stainless steel (corrosion-resistant environment) are available.
  • Various materials available: synthetic fibre, glass fibre.

Key Application Areas

  • Commercial buildings: fresh air systems in shopping malls, hotels, office buildings, protecting the end high-efficiency filter (HEPA).
  • Industrial manufacturing: middle section filtration in automobile spraying workshop, pharmaceutical factory, food factory, intercepting dust and oil mist.
  • Medical and Laboratory: air conditioning units in hospital operating theatres and PCR laboratories, used in conjunction with HEPA filters.
  • Electronics and Semiconductor: pre-filtration of clean rooms to extend the life of FFU (Fan Filter Unit).

Selection and Customisation Guide

Efficiency Selection

F5-F6: General ventilation (e.g. schools, offices).

Maintenance and Replacement Recommendations

Replacement cycle: usually 3-6 months (depending on the environmental dust concentration).

Differential pressure monitoring: It is recommended to install differential pressure gauge, and it needs to be replaced when the resistance reaches 2 times of the initial resistance.


With its high cost-effectiveness, flexible customisation and wide applicability, the medium efficiency bag filter has become a core component in the air treatment system. Users can choose the efficiency level, size and material according to the actual needs, with reasonable maintenance programme to achieve the goal of energy efficient air purification.
