Superior Structural Rigidity & High Airflow Capacity
We specialize in developing filtration solutions with exceptional stability, featuring a unique two layers’ skeletons design made of galvanized steel. This robust internal support ensures that the filter media remains perfectly stable even under a high rated air flow of 4000m³/h. This heavy-duty construction makes our filters the definitive choice for large-scale industrial ventilation and demanding AHU units.
Frequently Asked Questions
Q1: What specific filtration standard does this G4 Skeleton Filter meet?
This filter is precision-engineered to absorb above 5μm particles with a certified 40% (Arrestance) efficiency, meeting the rigorous requirements for G4 Efficiency Class.
Q2: How does the “Double-Layer Skeleton” design benefit air quality control?
The high-tensile Galvanized steel skeletons provide a rigid internal cage that prevents the media from fluttering or collapsing under pressure. This ensures that all air passes through the media without any bypass, which is critical for laboratory and hospital air intake
Q3: Can this filter help maintain stable pressure in clean air conditioning systems?
Yes. It is designed to operate at a stable and low initial resistance of 50Pa. This optimized pressure drop ensures balanced system pressure while handling a high air flow capacity.
Q4: What frame materials are used to ensure durability in technical environments?
We use precision-fitted Aluminum or Galvanized steel sheet frames combined with high-quality pre-filter media. This construction provides the necessary structural integrity for clean air conditioning systems and medical facilities.
Q5: Is this filter available in custom dimensions for specialized AHUs?
Absolutely. We offer a versatile range of dimensions from 295x295mm to 595x595mm, with industrial-standard thicknesses of 46mm and 96mm, allowing for a perfect fit in various air handling units.
