Vliesmo G4 Bag Filters Improve HVAC Efficiency for Industrial Air Quality

Core technical advantages

The G4 bag filter uses high-performance synthetic fiber media and a six-bag configuration that raises filtration surface area to 4.9 square meters. The expanded surface area increases dust-holding capacity while maintaining relatively low pressure loss throughout the service cycle, reducing system energy use.

An aluminum alloy frame provides structural durability for demanding industrial installations. The design is intended to maintain stable performance over extended operation.

Applications and selection guidance

The product is primarily used as a pre-filter in HVAC systems and industrial ventilation systems. It captures large dust particles and protects downstream high-efficiency filters, extending maintenance intervals for the overall system.

Selection considerations include the system’s maximum airflow and available installation space. The filter is available with or without a foam gasket to accommodate different sealing requirements.

Operating limits include a maximum temperature of 70°C and relative humidity up to 90%, allowing use in most indoor and industrial environments.

Maintenance and replacement

Replacement is indicated when operating pressure drop reaches 250 Pa, the recommended final resistance. A differential pressure gauge can monitor pressure across the filter and signal the need for service before airflow becomes unstable.
