Primary Skeleton Panel Filter | Two Layers’ Skeletons for High Air Flow HVAC
Engineered for high-demand ventilation, our Primary Skeleton Panel Filter features a robust two layers’ skeletons design made of galvanized steel. This unique internal skeleton support ensures the media remains stable even under a rated air flow of 4000m³/h. Specifically designed to absorb above 5μm particles, it is the ideal G3 / G4 efficiency stage for central air conditioning systems and large-scale industrial ventilation, maintaining a steady initial resistance of 50Pa.

Frequently Asked Questions
Q1: What makes the “Skeleton Type” filter different from a standard pre-filter?
-
The key difference is the two layers’ galvanized steel skeletons. This internal skeleton support provides maximum rigidity, ensuring the media stays perfectly in place even when subjected to a high air flow of 4000m³/h.
Q2: Can this filter handle large-scale industrial dust loads?
-
Yes. It is precision-engineered to absorb particles above 5μm with a certified G3/G4 efficiency. Its pleated design offers a large filter area, allowing it to manage high particulate loads while maintaining a low pressure drop.
Q3: Is the frame strong enough for heavy-duty AHU units?
-
Absolutely. We use a robust Aluminum or Galvanized steel sheet frame. When combined with the double-layer steel wire skeleton, it creates an anti-deformation cage that guarantees a long service life in industrial settings.
Q4: Will this filter help reduce my system’s energy consumption?
-
Yes. By maintaining a steady and low initial resistance of 50Pa, it allows your HVAC fans to operate more efficiently. The increased surface area from the pleats further helps in reducing overall energy costs.
Q5: What are the common sizes and thicknesses available for this model?
-
The most common industrial thicknesses are 46mm and 96mm. We also offer a range of standard dimensions, such as 595x595mm, or we can tailor the size to fit your specific system requirements.
