Frequently Asked Questions
Q1: Can this filter handle high-velocity air without the media shedding?
Yes. This model is reinforced with a rigid aluminum net face guard designed to withstand high-velocity air pressure. This prevents media migration and ensures the filter remains stable even at its maximum rated air flow of 4200m³/h.
Q2: Will the resistance increase significantly when operating at 300°C?
The filter is designed with a very low initial resistance of 40Pa. Because it uses high-quality fiber glass or synthetic media rated for 300°C, its structure remains stable under heat, maintaining efficient airflow throughout its service life.
Q3: Why is the “Flat Panel” design important for tunnel ovens?
The flat panel design ensures uniform air distribution across the entire surface of the media. For hot air tunnels, this uniformity is critical for maintaining consistent drying temperatures and high-quality production results.
Q4: Is the filter easy to install in large-scale industrial setups?
Absolutely. It features a lightweight Aluminum frame, making it easy to handle and install even in large-scale ventilation arrays or high-altitude maintenance points.
Q5: Are custom dimensions available for non-standard equipment?
Yes. While we offer standard sizes like 595x595x21mm, we specialize in providing customized specifications to meet unique system requirements, ensuring a perfect, airtight fit for any industrial oven.
