Panel filters G4 (595×595×46 mm): standard sizes and applications in Russia 

The products shown in the photograph belong to the category of panel frame filters of class G4. The design with corrugated filter material (fiberglass or synthetic fabric) provides increased dust capacity with low initial resistance. A metal protective mesh is installed on the reverse side (at the air outlet), which prevents deformation of the filter element under high loads and in conditions of high humidity.

In accordance with European standards EN 779 and Russian standards GOST R 56638, the following nominal dimensions (Width × Height × Depth) are most widespread in the Russian Federation:

1.595 × 595 × 46 mm - basic universal size (24″x24″). Used in the vast majority of air handling units (ASUs) and service sections of clean rooms.

2.495 × 495 × 46 mm - a compact option for modular systems and equipment of domestic production (20″×20″).

3.495 × 495 × 46 mm - a compact option for modular systems and equipment of domestic production (20″×20″).

Due to their cost-effectiveness and effectiveness in trapping coarse dust, sand and insects, G4 filters are in demand in the following sectors:

1.Data centers and server rooms:​ Protection of precision air conditioners from dust and poplar fluff, typical for the spring-summer period in the regions of the Russian Federation.

2. Shopping and entertainment centers (SECs) and business centers:​ Maintenance of central air conditioning systems in high traffic conditions.

3.Industrial workshops in regions with harsh climates:​ Protection against the penetration of snow chips and abrasive dust in the conditions of Siberia and the southern regions of the Russian Federation.

As a manufacturer with 27 years of experience, certified to ISO 9001/14001/45001 quality management systems, we understand that standard solutions are not always suitable for upgrading old ventilation systems. The 5,000 m² plant and 30 production lines allow us to produce up to 5 million units per year. We manufacture filters according to individual drawings (for example, dimensions 600×600 mm or complex configurations), including products with a reinforced frame or special aerodynamic requirements. The presence of 19 utility model patents confirms our technical capabilities in creating reliable filtration solutions.
